Psychedelic Drugs are Theorized to have Aided in Human Social Evolution

 

By John M. de Castro, Ph.D.

 

“psychedelics have profound cognitive, emotional, and social effects that inspired the development of cultures and religions worldwide.” – Michael J. Winkelman

 

Psychedelic substances such as peyote, mescaline, LSD, Bufotoxin, ayahuasca and psilocybin have been used almost since the beginning of recorded history to alter consciousness and produce spiritually meaningful experiences. Psychedelics produce effects that are similar to those that are reported in spiritual awakenings, a positive mood, with renewed energy and enthusiasm. It is easy to see why people find these experiences so pleasant and eye opening. They often report that the experiences changed them forever.

 

It is not known why the use of psychedelic substances have been so widely used throughout human evolution. Natural selection suggests that the use of these substances must confer some adaptive advantage, or their use would have ceased. What exactly are those advantages is a source of active debate in the scientific community. In today’s Research News article “Psychedelics, Sociality, and Human Evolution.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.729425/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1750137_a0P58000000G0YfEAK_Psycho_20211012_arts_A ) Arce and colleagues provide an evidence backed theoretical argument regarding the role of psychedelic substances in the evolution of humankind.

 

There is substantial evidence that early hominids routinely ingested fungi including mushroom that contained psychedelic substances. Early recorded history includes description of psychedelic uses in Mesoamerican societies. Indeed, psychedelic use has been recorded in early societies in Africa, Asia, Europe, Middle East, South America, Artic and Subarctic, and Central America. This suggests that there must be some instrumental effect of these substances that enhances the survival of humans.

 

Psilocybin and related psychedelics do not have physically toxic side effects. So, they can be ingested safely. The only evident problem is a change in cognition that could open “the possibility for errors in judgment, false perceptions, distortions, and illusions that could undermine an individual’s capacity for alertness, strategic thinking, and decision-making”. But early humans learned to use these substances in particular circumstances, such as rituals,  where the consequences of altered cognition could be minimized.

 

In their favor, psychedelic substances have been shown to improve coping with stress which was likely high in early hominid development. In addition, psychedelic substances have been used throughout history for the treatment of diseases and in recent years have been found to be effective in promoting recovery from a cancer diagnosis, relieving depression, and even in smoking cessation.

 

Psychedelic substances have traditionally been used in groups particularly around rituals and religious ceremonies which would improve social bonds, group cohesion, and pro-social behavior. This would facilitate social cooperation that was essential for early hominid group survival. Psychedelic substances have also been shown to enhance creative thinking and problem solving which would be of great use in adapting to changing environments.

 

These findings and arguments suggest that ingesting psychedelic substances may have been adaptive for humans increasing their chances of survival and procreation. It seems counterintuitive that ingesting substances that for the short term may make the individual less responsive and capable in the environment could actually improve survival. But that is what psychedelic substances appear to do. In this way ingesting psychedelic substances may be adaptive and thus be promoted in evolution.

 

So, psychedelic drugs are theorized to have aided in human social evolution

 

“psychedelic drugs. By simulating the effects of religious transcendence, they mimic states of mind that played an evolutionarily valuable role in making human cooperation possible – and with it, greater numbers of surviving descendants.” – James Carney

Study Summary

 

Rodríguez Arce JM and Winkelman MJ (2021) Psychedelics, Sociality, and Human Evolution. Front. Psychol. 12:729425. doi: 10.3389/fpsyg.2021.729425

 

Our hominin ancestors inevitably encountered and likely ingested psychedelic mushrooms throughout their evolutionary history. This assertion is supported by current understanding of: early hominins’ paleodiet and paleoecology; primate phylogeny of mycophagical and self-medicative behaviors; and the biogeography of psilocybin-containing fungi. These lines of evidence indicate mushrooms (including bioactive species) have been a relevant resource since the Pliocene, when hominins intensified exploitation of forest floor foods. Psilocybin and similar psychedelics that primarily target the serotonin 2A receptor subtype stimulate an active coping strategy response that may provide an enhanced capacity for adaptive changes through a flexible and associative mode of cognition. Such psychedelics also alter emotional processing, self-regulation, and social behavior, often having enduring effects on individual and group well-being and sociality. A homeostatic and drug instrumentalization perspective suggests that incidental inclusion of psychedelics in the diet of hominins, and their eventual addition to rituals and institutions of early humans could have conferred selective advantages. Hominin evolution occurred in an ever-changing, and at times quickly changing, environmental landscape and entailed advancement into a socio-cognitive niche, i.e., the development of a socially interdependent lifeway based on reasoning, cooperative communication, and social learning. In this context, psychedelics’ effects in enhancing sociality, imagination, eloquence, and suggestibility may have increased adaptability and fitness. We present interdisciplinary evidence for a model of psychedelic instrumentalization focused on four interrelated instrumentalization goals: management of psychological distress and treatment of health problems; enhanced social interaction and interpersonal relations; facilitation of collective ritual and religious activities; and enhanced group decision-making. The socio-cognitive niche was simultaneously a selection pressure and an adaptive response, and was partially constructed by hominins through their activities and their choices. Therefore, the evolutionary scenario put forward suggests that integration of psilocybin into ancient diet, communal practice, and proto-religious activity may have enhanced hominin response to the socio-cognitive niche, while also aiding in its creation. In particular, the interpersonal and prosocial effects of psilocybin may have mediated the expansion of social bonding mechanisms such as laughter, music, storytelling, and religion, imposing a systematic bias on the selective environment that favored selection for prosociality in our lineage.

Spirituality is Related to Reduced Depression but Negative Religiosity is Associated with Suicidality

Spirituality is Related to Reduced Depression but Negative Religiosity is Associated with Suicidality

 

By John M. de Castro, Ph.D.

 

“The trouble is that just as it is hard to feel connected to other people while depressed, it is difficult to feel connected to God. A leap of trust and faith is frequently needed to be spiritual while depressed.” – Healthtalk.org

 

Depression and other mood disorders are the number-one risk factor for suicide. More than 90% of people who kill themselves have a mental disorder, whether depression, bipolar disorder or some other diagnosis. So, the best way to prevent suicide may be to treat the underlying cause. For many this means treating depression.

 

Spirituality is defined as “one’s personal affirmation of and relationship to a higher power or to the sacred. There have been a number of studies of the influence of spirituality on the physical and psychological well-being of practitioners mostly showing positive benefits, with spirituality encouraging personal growth and mental health. Spirituality may help to provide meaning and prevent suicide. But there is scant research on the relationship of spirituality and religiosity and suicide.

 

In today’s Research News article “Comparison of religiosity and spirituality in patients of depression with and without suicidal attempts.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8221206/ ) Dua and colleagues

CMCS – Center for Mindfulness and Contemplative Studies recruited 2 groups of patients both with depression and suicidal ideation and one with an additional suicide attempt. They also recruited age and gender matched healthy control participants. They completed measures of the depression, impulsivity, hopelessness, anxiety, irritability, mania, suicide severity, centrality of religion and spiritual attitudes.

 

They found that the depressed groups did not differ in purpose, hope, and organized, nonorganized religious activities and intrinsic religiosity. On the other hand, patients with suicidal ideation generally had a family history of suicide. Patients who had attempted suicide were significantly higher in hopelessness and suicide ideation and lower on social support than patients who had nor attempted suicide. They also had significantly higher levels of negative religious coping. Compared to the healthy controls the depressed groups were significantly lower in religiosity. They also found that the lower the levels of religiosity the greater the levels of suicidal ideation and the higher the number of suicide attempts. But, in the suicide attempters higher levels of ideological religiosity was associated with greater severity of suicide ideation.

 

These are interesting but correlative findings and as such causation cannot be determined. Nevertheless, the results suggest that spirituality, although associated with lower depression, is not significantly related to suicide ideation or attempts. On the other hand, negative religious coping, ideological religiosity, and low religiosity were. In other words, being religious, in general is not a problem. But adhering to the ideology or using negative religious coping are associated with suicidality.

 

Negative religious coping involves struggling with religion, questioning, guilt, and perceived distance from and negative views of god. This type of coping does not provide support in times of psychological distress and in fact may exacerbate feelings of hopelessness. Regardless, it appears that non-spiritual uses and ideas about religion and god my be associated with more thoughts about suicide and an increased likelihood of attempting suicide.

 

So, spirituality is related to reduced depression but negative religiosity is associated with suicidality.

 

“Whether your depression manifests itself as a loss of appetite, decreased sense of self-worth, lost productivity, feelings of helplessness, prolonged worry or any other symptom, spirituality can absolutely help an individual along their journey toward purpose.” – Pyramid Healthcare

Abstract

Aim:

This study is aimed to compare the religiosity and spirituality of patients with first-episode depression with suicidal ideation and those with recent suicidal attempts. Additional aim was compare the religiosity and spirituality of patients with first-episode depression with healthy controls.

Methods:

Patients of first episode depression with suicidal ideation and healthy controls were assessed by Centrality of Religiosity Scale (CRS), Duke University Religion Index (DUREL), Brief Religious coping scale (R-COPE), and Spiritual Attitude Inventory (SAI).

Results:

Patients with depression were divided into two groups based on the presence (n = 53) or absence (n = 62) of suicidal attempts in the previous 14 days. Both the patients with and without suicide attempts were matched for depression severity. Both the patient groups did not differ in terms of religiosity and spirituality as assessed using CRS and SAI. Both depression groups had lower scores on religiosity as compared to healthy controls as assessed on CRS. The two groups also had a lower score on the “sense of hope” which is a part of SAI, when compared to healthy controls. Compared to patients without suicide attempts (i.e., ideators group) and healthy controls, subjects with suicide attempts more often used negative religious coping. Total numbers of lifetime suicide attempts in the attempt group were associated with the ideology domain of the CRS.

Conclusion:

Compared with healthy controls, patients with depression have lower levels of religiosity and spirituality. In the presence of comparable severity of depression, higher use of negative religious coping is associated with suicide attempts.

Reduce Depression in Older Adults with Mind-Body Practices and Exercise

Reduce Depression in Older Adults with Mind-Body Practices and Exercise

 

By John M. de Castro, Ph.D.

 

“Complementary use of mindful exercise, such as Tai Chi and yogic meditation, can improve clinical outcomes of mood disorders in older adults-as demonstrated in brain scans, biomarkers of cellular aging, and mental health rating scales.” – Arline Kaplan

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. This includes our cognitive (mental) abilities and mood. It is inevitable and cannot be avoided. There is some hope for age related decline, however, as there is evidence that it can be slowed. There are some indications that physical and mental exercise can reduce the rate of decline. For example, contemplative practices such as meditation, yoga, and Tai Chi or qigong have all been shown to be beneficial in slowing or delaying physical and mental decline with aging and with improving depression. The research has been accumulating. So, it makes sense to pause and review and summarize what has been learned.

 

In today’s Research News article “Aerobic, resistance, and mind-body exercise are equivalent to mitigate symptoms of depression in older adults: A systematic review and network meta-analysis of randomised controlled trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8191520/ ) Miller and colleagues review, summarize, and perform a meta-analysis of the published randomized controlled trials of the effectiveness of mind-body practices, aerobic exercise, and resistance exercise on depression in older adults (over 65 years of age). They identified 69 published research studies including a total of 5,379 elderly participants.

 

They report that the published research found that in comparison to usual care, wait-list controls, or attention controls that mind-body practices, aerobic exercise, and resistance exercise all significantly reduced depression in the elderly participants. Although no significant differences were found between the practices, on average, the effectiveness of the practices were rank ordered mind-body practices followed by aerobic exercise followed by resistance exercise.

 

All three practices involve exercise. Mind-body practices include yoga, Tai Chi, and Qigong all of which provide gentle mild exercise intensity. Aerobic exercise on the other hand provides moderate intensity exercise. This suggests that the intensity of exercise is not important for the relief of depression. What does appear to be important is that exercise be incorporated into the activities of the elderly to raise mood and reduce depression. Hence, the results suggest that the depression that is common in the elderly can be ameliorated with exercise.

 

So, reduce depression in older adults with mind-body practices and exercise.

 

“Higher physical activity levels among older adults in particular may have a preventive effect on the development of depression.36 Recent findings point to the potential efficacy of exercise as a treatment of depression in older adults, in some cases with similar efficacy to antidepressants.” – Maren Nyer

Abstract

Background: Exercise has been identified as an allied health strategy that can support the management of depression in older adults, yet the relative effectiveness for different exercise modalities is unknown. To meet this gap in knowledge, we present a systematic review and network meta-analysis of randomised controlled trials (RCTs) to examine the head-to-head effectiveness of aerobic, resistance, and mind-body exercise to mitigate depressive symptoms in adults aged ≥ 65 years.

Methods: A PRISMA-NMA compliant review was undertaken on RCTs from inception to September 12 th, 2019. PubMed, Web of Science, CINAHL, Health Source: Nursing/Academic Edition, PsycARTICLES, PsycINFO, and SPORTDiscus were systematically searched for eligible RCTs enrolling adults with a mean age ≥ 65 years, comparing one or more exercise intervention arms, and which used valid measures of depressive symptomology. Comparative effectiveness was evaluated using network meta-analysis to combine direct and indirect evidence, controlling for inherent variation in trial control groups.

Results: The systematic review included 82 RCTs, with 69 meeting eligibility for the network meta-analysis ( n = 5,379 participants). Pooled analysis found each exercise type to be effective compared with controls (Hedges’ g = -0.27 to -0.51). Relative head-to-head comparisons were statistically comparable between exercise types: resistance versus aerobic (Hedges’ g = -0.06, PrI = -0.91, 0.79), mind-body versus aerobic (Hedges’ g = -0.12, PrI = -0.95, 0.72), mind-body versus resistance (Hedges’ g = -0.06, PrI = -0.90, 0.79). High levels of compliance were demonstrated for each exercise treatment.

Conclusions: Aerobic, resistance, and mind-body exercise demonstrate equivalence to mitigate symptoms of depression in older adults aged ≥ 65 years, with comparably encouraging levels of compliance to exercise treatment. These findings coalesce with previous findings in clinically depressed older adults to encourage personal preference when prescribing exercise for depressive symptoms in older adults.

Relieve Cancer-Related Fatigue in Breast Cancer Patients with Mind-Body Exercise

Relieve Cancer-Related Fatigue in Breast Cancer Patients with Mind-Body Exercise

 

By John M. de Castro, Ph.D.

 

“mindfulness has both direct and indirect effects on the fatigue of breast cancer survivors and that mindfulness can be used to more effectively reduce their fatigue.” – Kaori Ikeuchi

 

Receiving a diagnosis of breast cancer has a huge impact on most people. Feelings of depression, anxiety, and fear are very common and are normal responses to this life-changing and potentially life-ending experience. But breast cancer diagnosis is not necessarily a death sentence. Over half of the people diagnosed with breast cancer are still alive 10 years later and this number is rapidly increasing. But surviving breast cancer carries with it a number of problems. Anxiety, depression, fatigue and insomnia are common symptoms in the aftermath of surviving breast cancer. These symptoms markedly reduce the quality of life of the patients.

 

Mindfulness training has been shown to help with cancer recovery and help to relieve chronic pain. It can also help treat the residual physical and psychological symptoms, including stress, sleep disturbance, fear, and anxiety and depression. Mind-body practices such as Tai Chi or Qigong, and yoga have been shown to be effective in improving the psychological symptoms occurring in breast cancer patients. The research has been accumulating. So, it makes sense to review and summarize what has been learned.

 

In today’s Research News article “A Meta-Analysis: Intervention Effect of Mind-Body Exercise on Relieving Cancer-Related Fatigue in Breast Cancer Patients.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8275388/ ) Liu and colleagues review, summarize, and perform a meta-analysis of the published randomized controlled trials on the effectiveness of mind-body practices in relieving the chronic fatigue that occurs in breast cancer survivors. They identified 17 published randomized controlled trials that included a total of 1133 breast cancer patient. The mind-body practices employed in the published trials were yoga, Tai Chi, and Qigon.

 

They report that the published research found that mind-body practices significantly reduced the fatigue of patients with breast cancer. They further found that Tai Chi practice produced significantly greater reductions in fatigue than yoga practice and that practicing for over 40 minutes duration produces greater reductions in fatigue than shorter practice durations. Hence, the published research to date suggests that practicing yoga and particularly Tai Chi can successfully reduce cancer-related fatigue in patients with breast cancer. This is important as fatigue greatly interferes with the quality of life of the patients and their ability to reengage in normal daily activities. Mind-body practices, then, can improve the lives of breast cancer patients.

 

So, relieve cancer-related fatigue in breast cancer patients with mind-body exercise.

 

“Mindfulness-and in particular nonreactivity, nonjudging, and describing-may be a personal resource for women with metastatic breast cancer in coping with complex symptoms of this life-threatening illness.” – Lauren A Zimmaro

Abstract

Objective

This paper aims to systematically evaluate the intervention effect of mind-body exercise on cancer-related fatigue in breast cancer patients.

Methods

Databases including PubMed, the Cochrane Library, Embase, Web of Science, CNKI, Wanfang Data, and SINOMED were retrieved to collect randomized controlled trials on the effects of mind-body exercise on relieving cancer-related fatigue in breast cancer patients. The retrieval period started from the founding date of each database to January 6, 2021. Cochrane bias risk assessment tools were used to evaluate the methodological quality assessment of the included literature, and RevMan 5.3 software was used for meta-analyses.

Results

17 pieces of researches in 16 papers were included with a total of 1133 patients. Compared with the control group, mind-body exercise can improve cancer-related fatigue in breast cancer patients. The combined effect size SMD = 0.59, 95% CI was [0.27, 0.92], p < 0.00001. Doing Tai Chi for over 40 minutes each time with an exercise cycle of ≤6 weeks can improve cancer-related fatigue in breast cancer patients more significantly. Sensitivity analysis shows that the combined effect results of the meta-analysis were relatively stable.

Conclusion

Mind-body exercise can effectively improve cancer-related fatigue in breast cancer patients.

Strengthen the Brain and Improve Cognition in Older Adults with Mindfulness

Strengthen the Brain and Improve Cognition in Older Adults with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness training, with its emphasis on present-focused attention and regulation of the habitual, reflexive tendencies of the mind, has the potential to enhance cognitive control operations in the elderly and the neural circuitry associated with it.” – Ruchika S Prakash

 

The aging process involves a systematic progressive decline of the body and the brain. Every system in the body deteriorates including cognitive function (thinking ability) and motor function with a decline in strength, flexibility, and balance. There is some hope as there is evidence that these declines can be slowed. For example, a healthy diet and a regular program of exercise can slow the physical and cognitive decline of the body with aging. Also, contemplative practices such as meditation, yoga, and tai chi or qigong have all been shown to be beneficial in slowing or delaying physical and mental decline. Research has found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners.

 

In today’s Research News article “Mindfulness Training Improves Cognition and Strengthens Intrinsic Connectivity Between the Hippocampus and Posteromedial Cortex in Healthy Older Adults.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8430251/ ) Sevinc and colleagues recruited healthy elderly participants (aged 65 to 80 years) who were evaluated as cognitively normal and randomly assigned them to receive either mindfulness training or cognitive fitness training. Mindfulness training was delivered in 8 weekly 105 minute sessions and was modelled after the Mindfulness-Based Stress Reduction (MBSR) program containing training in meditation, body scan, and yoga along with discussion and daily home practice. The cognitive fitness training consisted of 8 weekly 1-hour sessions of word finding and crossword puzzle solving along with home puzzle solving. They were measured before and after training for memory and cognitive performance. In addition, their brains were scanned before and after training with Magnetic Resonance Imaging (MRI).

 

They found that in comparison to baseline the group that received mindfulness training had significant increases in cognitive performance, primarily due to episodic memory improvement, while the cognitive fitness training group did not. The brain scans revealed that the mindfulness group had increased functional connectivity between the hippocampus and the angular gyrus. Additionally, the improved cognitive performance after mindfulness training was associated with increased connectivity between the precuneus and the hippocampus.

 

The findings suggest that mindfulness training improves cognition in cognitively intact elderly individuals. This may be why mindfulness training has been shown to reduce age related cognitive decline and dementia. The results also suggest that these improvements in cognition may be related to changes in the connectivity of the brain. The observed changes produced by mindfulness training were in the connectivity between the hippocampus and the precuneus and between the hippocampus and the angular gyrus. These are structures included in what is known as the brain’s default mode network, which is known to have decreased activity in association with age-related cognitive decline. So, the improved connectivity may indicate that mindfulness training protects the brain from deterioration associated with aging and this may be responsible for improved cognition in the elderly.

 

So, strengthen the brain and improve cognition in older adults with mindfulness.

 

“recent research suggests about how mindfulness meditation practice may help keep aging brains fit and functional.” – Grace Bullock

Abstract

Maintaining optimal cognitive functioning throughout the lifespan is a public health priority. Evaluation of cognitive outcomes following interventions to promote and preserve brain structure and function in older adults, and associated neural mechanisms, are therefore of critical importance. In this randomized controlled trial, we examined the behavioral and neural outcomes following mindfulness training (n = 72), compared to a cognitive fitness program (n = 74) in healthy, cognitively normal, older adults (65–80 years old). To assess cognitive functioning, we used the Preclinical Alzheimer Cognitive Composite (PACC), which combines measures of episodic memory, executive function, and global cognition. We hypothesized that mindfulness training would enhance cognition, increase intrinsic functional connectivity measured with magnetic resonance imaging (MRI) between the hippocampus and posteromedial cortex, as well as promote increased gray matter volume within those regions. Following the 8-week intervention, the mindfulness training group showed improved performance on the PACC, while the control group did not. Furthermore, following mindfulness training, greater improvement on the PACC was associated with a larger increase in intrinsic connectivity within the default mode network, particularly between the right hippocampus and posteromedial cortex and between the left hippocampus and lateral parietal cortex. The cognitive fitness training group did not show such effects. These findings demonstrate that mindfulness training improves cognitive performance in cognitively intact older individuals and strengthens connectivity within the default mode network, which is particularly vulnerable to aging affects.

Reduce Adolescent Internalizing Symptoms, and Impulsivity with Mindfulness

Reduce Adolescent Internalizing Symptoms, and Impulsivity with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness appears to be a way of engaging with our internal and external environment and approaching emotion that is an asset for avoiding excessively heightened internalizing symptoms.” – Sarah Clear

 

Adolescence is a time of mental, physical, social, and emotional growth. But it can be a difficult time, fraught with challenges. During this time the child transitions to young adulthood; including the development of intellectual, psychological, physical, and social abilities and characteristics. There are so many changes occurring during this time that the child can feel overwhelmed and unable to cope with all that is required. This can lead to emotional and behavioral problems. Indeed, up to a quarter of adolescents suffer from internalizing symptoms such as depression or anxiety disorders, and an even larger proportion struggle with subclinical symptoms. Mindfulness training has been shown to improve emotion regulation and to benefit the psychological and emotional health of adolescents

 

In today’s Research News article “Longitudinal Associations between Internalizing Symptoms, Dispositional Mindfulness, Rumination and Impulsivity in Adolescents.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8416885/ ) Royuela-Colomer and colleagues recruited healthy adolescents (aged 11 to 17 years) and had them complete measures of mindfulness, rumination, impulsivity, and internalizing symptoms, including anxiety, depression, and perceived stress. The measures were completed again one year later.

 

They found that adolescent boys had significantly lower levels of rumination, impulsivity, and internalizing symptoms and higher levels of mindfulness than girls. They also found that at both measurement periods the higher the levels of mindfulness the lower the levels of all dependent variables. They further found that the higher the levels of mindfulness at the first measurement the lower the levels of depression, perceived stress, and impulsivity a year later. This latter finding was true both for boys and girls.

 

These findings are correlational. So, no conclusions about causation can be made. But in previous controlled studies mindfulness has been found to improve the psychological well-being of adolescents and to produce lower levels of depression, perceived stress, and impulsivity. So, the correlations obtained here likely occurred due to causal connections between the variables. These results then suggest that mindfulness may be protective against internalizing symptoms and impulsivity in adolescents. This further suggests that mindfulness training should be made part of the education of adolescents to improve their psychological well-being and reducing their destructive tendencies toward impulsive behavior.

 

So, reduce adolescent internalizing symptoms, and impulsivity with mindfulness.

 

“Mindfulness not only directly impacted on adolescents’ internalizing problems, but also indirectly improved their anxious and depression emotions via the reduction of rumination and the increase of acceptance.” – Meng Yu

Abstract

Mindfulness has been associated with fewer negative mental health symptoms during adolescence, but fewer studies have examined longitudinal associations between mindfulness and symptoms in conjunction with two vulnerability factors for psychopathology with mindfulness: rumination and impulsivity. This study examined longitudinal associations between internalizing symptoms (depression, anxiety, stress), mindfulness, rumination, and impulsivity over a one-year period among 352 Spanish adolescents (57.4% girls; M = 14.47, SD = 1.34). Participants completed self-reported measures of symptoms, mindfulness, rumination, and impulsivity at two time points. Mindfulness negatively predicted stress and depressive symptoms, and a bidirectional negative association was found between mindfulness and impulsivity. Impulsivity positively predicted stress, and anxiety positively predicted depressive symptoms, stress, and rumination. This study highlights the importance of mindfulness as a protective factor and impulsivity and anxiety as risk factors for internalizing symptoms throughout adolescence. These findings build on previous studies that examined longitudinal associations between mindfulness and symptoms by including rumination and impulsivity’s roles.

Improve the Psychological Health of College Students with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness can help students who might be struggling, in particular medical students, find new ways of relating to the difficulties that arise in their clinical work, studying and wellbeing.” – Alice Malpass

 

In the modern world education is a key for success. Where a high school education was sufficient in previous generations, a college degree is now required to succeed in the new knowledge-based economies. There is a lot of pressure on university students to excel so that they can get the best jobs after graduation. This stress might in fact be counterproductive as the increased pressure can lead to stress and anxiety which can impede the student’s physical and mental health, well-being, and school performance.

 

It is, for the most part, beyond the ability of the individual to change the environment to reduce stress, so it is important that methods be found to reduce the college students’ responses to stress; to make them more resilient when high levels of stress occur. Contemplative practices including meditation, mindfulness training, and yoga practice have been shown to reduce the psychological and physiological responses to stress. Indeed, these practices have been found to reduce stress and improve psychological health in college students. So, it would seem important to summarize what has been learned about mindfulness-based approaches to improve the psychological well-being of college students studying to become health professionals.

 

In today’s Research News article “Mindfulness-Based Approaches for Managing Stress, Anxiety and Depression for Health Students in Tertiary Education: a Scoping Review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8435111/ ) Parsons and colleagues review and summarize the published research studies investigating the effectiveness of mindfulness-based approaches to improve the psychological well-being of college students studying to become health professionals. They identified 24 published research studies.

 

They report that the published research studies found that mindfulness-based training produced significant reductions in perceived stress, anxiety, and depression in the health students. Hence, these health students had similar responses to mindfulness training as has been observed in a large number of studies with a variety of healthy and ill participants. This suggests that it would be beneficial to incorporate mindfulness training in the curriculum of college students studying to become health professionals. This should improve their ability to learn their professions and become more resilient and effective professionals.

 

So, improve the psychological health of college health students with mindfulness.

Abstract

Objectives

High rates of depression, anxiety and stress are reported in tertiary health students. Mindfulness-based programs have been included in the training of health students to help them manage depression, anxiety and stress; however, to date, there has been no review of best practice implementation of mindfulness for health students. The aim of this review was to evaluate the outcomes of mindfulness-based practice for health students to inform best practice with this population.

Methods

A comprehensive search was conducted of three electronic databases (PsychINFO, Medline and Embase) guided by the five-step systematic process for conducting scoping reviews to investigate mindfulness-based intervention programs for students enrolled in a tertiary institution in a health-related course.

Results

Twenty-four papers met the eligibility criteria and were reviewed in detail. Findings suggested that mindfulness-based intervention approaches are useful in decreasing depression, anxiety and stress in health students; however, challenges exist in student engagement and retention. Generalization of results was limited by the heterogeneous population, intervention designs and delivery methods, as well as a lack of standardized outcome measures.

Conclusion

The inclusion of mindfulness-based programs within tertiary curricula can be an effective approach to assist with managing depression, stress and anxiety in health students. Providing academic credit to students, improving translation of skills to working with future clients, and embedding mindfulness-based programs within the curriculum could improve engagement and retention.

Mindfulness Improves the Psychological Well-Being of Teachers in Non-Western Societies

 

By John M. de Castro, Ph.D.

 

“Teachers who practice “mindfulness” are better able to reduce their own levels of stress and prevent burnout.” – Dee DiGioia

 

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. This often produces burnout; fatigue, cynicism, emotional exhaustion, and professional inefficacy. Teachers experience burnout at high rates. Roughly a half a million teachers out of a workforce of three million, leave the profession each year and the rate is almost double in poor schools compared to affluent schools. Indeed, nearly half of new teachers leave in their first five years.

 

Burnout frequently results from emotional exhaustion. This exhaustion not only affects the teachers personally, but also the students, as it produces a loss of enthusiasm, empathy, and compassion. Regardless of the reasons for burnout or its immediate presenting consequences, it is a threat to schools and their students. In fact, it is a threat to the entire educational systems as it contributes to the shortage of teachers. Hence, methods of reducing stress and improving teacher psychological health needs to be studied.

 

Mindfulness techniques are gaining increasing attention for the treatment of the symptoms of stress and burnout. They have been demonstrated to be helpful in reducing the psychological and physiological responses to stress and for treating and preventing burnout in a number of work environments including schools. But most of the research focuses on teachers in Western societies. There is a need to study if mindfulness is equally effective in Eastern societies.

 

In today’s Research News article “Effectiveness and Mechanisms of Mindfulness Training for School Teachers in Difficult Times: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8443903/ ) Tsang and colleagues recruited elementary and secondary school teachers in Hong Kong and randomly assigned them to either a wait-list or to receive 8 weekly 90-minute sessions of mindfulness training along with home practice. The mindfulness training was based upon the Mindfulness-Based Stress Reduction (MBSR) and the Mindfulness-Based Cognitive Therapy (MBCT) programs. They were measured before and after training and two months later for mindfulness, general health, insomnia, stress, positive and negative emotions, life satisfaction, emotion regulation, and mindfulness in teaching.

 

They found that in comparison to baseline and the wait-list group, the teachers who had received mindfulness training had significantly higher levels of mindfulness, general health, positive emotions, life satisfaction, emotion regulation, and mindfulness in teaching and significantly lower levels of insomnia, stress, and negative emotions that were maintained at the 2-month follow-up measurement. In addition, a mediation analysis demonstrated that mindfulness was associated with well-being directly and indirectly via emotion regulation such that mindfulness was associated with increased emotion regulation that was in turn associated with increased well-being. Similarly, mindfulness was associated with mindfulness in teaching directly and indirectly via well-being such that mindfulness was associated with increased well-being that was in turn associated with increased mindfulness in teaching.

 

The present study had a passive control condition, wait-list, and this leaves a number of potential confounding explanations of the results such as placebo effects, attentional effects, and experimenter bias. But a large amount of previous controlled research has demonstrated that mindfulness training produces increases in health, positive emotions, emotion regulation, and life satisfaction, and decreases in insomnia, stress, and negative emotions. So, the present benefits are likely due to the mindfulness training.

 

The findings are important as they demonstrate that teachers in an Eastern society were benefited by mindfulness training to the same extent and in the same ways as teachers in Western societies. Thus, the effects of mindfulness training appear to be universal, regardless of culture. The findings also demonstrate that mindfulness training has direct and indirect effects on well-being that similarly effects mindfulness in teaching. All of this suggests that mindfulness training improves the psychological well-being of teachers which likely makes them happier and more effective teachers.

 

So, mindfulness improves the psychological well-being of teachers in non-western societies

Advance online publication. https://doi.org/10.1007/s12671-021-01750-1

 

Abstract

Objectives

Research in recent years has shown that mindfulness-based interventions can enhance teachers’ mental and physical health. However, the existing studies were predominantly conducted in Western, educated, industrialized, rich, and democratic (WEIRD) societies. As a randomized controlled trial in a non-WEIRD society, the present study examined the effectiveness and mechanisms of mindfulness training for Hong Kong teachers in difficult times.

Methods

Teachers from primary and secondary schools (n = 186) were randomly assigned to mindfulness training (eight-week .b Foundations) or waitlist control condition. They completed online self-report surveys on measures of well-being, emotion management, and mindfulness in teaching at baseline, post-intervention, and two-month follow-up.

Results

The intervention group reported significantly higher levels of life satisfaction, positive affect, general health, along with significantly lower levels of insomnia, stress, and negative affect than the control group at post-test and two-month follow-up. The effect sizes were medium to large (ηp2 = 0.06 to 0.14). More importantly, teachers’ baseline well-being had a significant moderating effect on the intervention effectiveness. Those with a lower baseline in well-being benefitted more than their counterparts with a higher baseline. In addition, teachers’ emotion management was found to be the mediator through which mindfulness training enhanced teachers’ well-being. Such improvement in well-being also predicted higher levels of mindfulness in teaching.

Conclusions

This study provides evidence on the efficacy of mindfulness training for teachers beyond WEIRD societies. It suggests the universality and practicality of mindfulness training in enhancing teachers’ well-being and reducing their distress in difficult times.

Improve the Psychological Well-Being of Social Care Workers with Mindfulness

Improve the Psychological Well-Being of Social Care Workers with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindfulness also helps social workers with self-care . . . allowing them to notice when they’re getting overwhelmed and recognize signs of burnout earlier. Social workers . . . deal with extremely difficult things, and mindfulness can help them not feel overloaded.” – Kate Jackson

 

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. In high stress occupations, like social work, burnout is all too prevalent. Burnout is the fatigue, cynicism, emotional exhaustion, sleep disruption, and professional inefficacy that comes with work-related stress. Improving the psychological health of individuals involved in social care, then, has to be a priority.

 

Contemplative practices have been shown to reduce the psychological and physiological responses to stress. Indeed, mindfulness has been shown to be helpful in treating and preventing burnout, increasing resilience, and improving sleep.  It makes sense that intervening early in the training for professional social care workers would help prevent later stress effects and burnout. Hence, it is reasonable to examine the ability of mindfulness training to improve the well-being of students preparing for careers as social care professionals.

 

In today’s Research News article “Effects of Mindfulness-Based Stress Reduction on Health and Social Care Education: a Cohort-Controlled Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8190752/ ) Lo and colleagues recruited postgraduate students in social work, family therapy, or counseling and assigned them to either a no-treatment control or to receive 8 weekly, 2.5-hour sessions of Mindfulness-Based Stress Reduction (MBSR). The MBSR program consists of practice with meditation, yoga, and body scan, along with discussion and home practice. They were measured before and after training for burnout, perceived stress, work engagement, physical stress, empathy, and time in home practice.

 

They found that in comparison to baseline and the no-treatment control group the group that received Mindfulness-Based Stress Reduction (MBSR) had significantly lower levels of perceived stress, physical distress, burnout, emotional exhaustion, and depersonalization of the client, and significantly higher levels of vigor. Hence, they found that participation in the MBSR program resulted in significant improvement in the psychological health of social care postgraduate students.

 

It should be noted that the present study used a weak research design that lacked random assignment of participants to groups, an active control condition, and follow-up measurements. This leave the interpretation open to confounding explanations and does not determine if the effects are lasting. Future studies should employ random assignment, an active control condition, e.g. exercise, and follow-up measurements.

 

But previous better controlled research has demonstrated that mindfulness training increases vigor and reduces perceived stress, distress, burnout, and emotional exhaustion. So, the present results, at least in part, are likely due to the ability of Mindfulness-Based Stress Reduction (MBSR) training to improve psychological health. This suggests that the psychological health and resistance to stress and burnout in students preparing for careers as social care professionals can be strengthened by mindfulness training. This may better prepare them to deal with the stresses of their professional careers and make them more effective professionals.

 

So, improve the psychological well-being of social care workers with mindfulness.

Abstract

Objectives

Mindfulness practice has been recommended as part of health and social care education and training because of its potential benefits in fostering clinical skills and attitudes, increasing self-care, and reducing the effect of stress in education and occupation. The objectives of this study were to evaluate the effects of a mindfulness-based stress reduction (MBSR) program on stress, physical distress, job burnout, work engagement, and empathy for health and social care education.

Methods

Students (N = 124) from postgraduate programs in social work, counseling, and family therapy were recruited. Sixty-four students participated in an 8-week MBSR program as an elective course. Sixty students were recruited from other elective courses in the same cohort as control group participants. All participants completed self-report assessments.

Results

The results suggested that MBSR was associated with significant improvements in perceived efficacy and vigor and significant reductions in physical distress, total job burnout, emotional exhaustion, and depersonalization of clients compared with the control group.

Conclusions

This study contributes to the growing body of literature highlighting the potential use of mindfulness practice to improve students’ personal well-being and professional growth in health and social care education. Mindfulness practice should be further promoted in health and social care education and training.

Improve Worker’s Psychological Wellbeing and Work Engagement and Performance with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindfulness impacts the individual holistically. This impact translates quickly into the workplace and appears as shifts in the approach to work, in changes in mindsets and in being present more, among others, opening the possibility for employees to impact the bottom line through these changes.” – Fabiola Fajardo

 

Work is very important for our health and well-being. We spend approximately 25% of our adult lives at work. How we spend that time is immensely important for our psychological, social, and physical health. But nearly 2/3 of employees worldwide are unhappy at work. This is partially due to work-related stress which is epidemic in the western workplace. Almost two thirds of workers report high levels of stress at work. This stress can result in impaired health and can result in burnout, producing fatigue, cynicism, and professional inefficacy.

 

To help overcome unhappiness, stress, and burnout, mindfulness practices have been implemented in the workplace. Indeed, mindfulness practices have been shown to markedly reduce the physiological and psychological responses to stress. As a result, it has become very trendy for business to incorporate meditation into the workday to help improve employee well-being, health, and productivity. These programs attempt to increase the employees’ mindfulness at work and thereby reduce stress.

 

In today’s Research News article “Differential Effects of Mindfulness-Based Intervention Programs at Work on Psychological Wellbeing and Work Engagement.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.715146/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1741394_a0P58000000G0YfEAK_Psycho_20210930_arts_A ) Calcagni and colleagues recruited “white collar” workers and randomly assigned them to receive either mindfulness training based upon the Mindfulness-Based Cognitive Therapy (MBCT) program or to a wait-list control condition. The mindfulness training occurred in either 6 weekly 2-hour sessions of 3 weekly 4-hour sessions along with daily home practice. They were measured before and 1-week after training for mindfulness, psychological well-being, work engagement, work performance, and perceived stress.

 

They found that in comparison to baseline and the wait-list control group, the mindfulness group had significantly lower levels of perceived stress and significantly higher levels of mindfulness, including the describe, acting with awareness, and no-reactivity subscales. They also had significantly higher levels of psychological well-being, including the positive relations, autonomy, and environmental mastery subscales. For work engagement they found significantly higher levels for the mindfulness group including the vigor and absorption subscales. Finally, after training the mindfulness group had significantly higher levels of work performance including the in-role and extra-role subscales.

 

It appears that mindfulness training of “white collar” workers produces improved psychological well-being, engagement with work and job performance. These results are similar to those observed in previous research in a wide variety of contexts and participants including improves well-being and work engagement and performance. So, mindfulness training is an effective method to improve the work and psychological health of “white collar” workers. These results suggest that mindfulness training would reduce the likelihood of burnout and improve retention of workers. This provides support for mindfulness training in work environments.

 

So, improve worker’s psychological wellbeing and work engagement and performance with mindfulness.

Calcagni CC, Salanova M, Llorens S, Bellosta-Batalla M, Martínez-Rubio D and Martínez Borrás R (2021) Differential Effects of Mindfulness-Based Intervention Programs at Work on Psychological Wellbeing and Work Engagement. Front. Psychol. 12:715146. doi: 10.3389/fpsyg.2021.715146

 

Two different mindfulness-based interventions were deployed in a sample of white-collar workers to explore the differential effects on different facets of mindfulness, dimensions of psychological wellbeing, work engagement, performance, and stress of a participant. A total of 28 participants completed one of the different programs, and their results were compared between groups and against 27 participants randomly allocated to a waiting list control group. Results suggest both mindfulness intervention programs were successful at increasing the levels of psychological wellbeing, work engagement, and performance of the participants, as well as decreasing their levels of stress. Significant differences were found between the two programs in all outcome variables. Results suggest that brief and customized mindfulness interventions at work are as successful as lengthier programs.
