Mindfulness Increases the Ability to Change Behavior for the Good

 

By John M. de Castro, Ph.D.

 

“Training your mind to be in the present moment is the #1 key to making healthier choices.” – Susan Albers

 

Many health problems are behavioral problems or have their origins in maladaptive behavior. This is evident in car accident injuries that are frequently due to behaviors, such as texting while driving, driving too fast or aggressively, or driving drunk. Other problematic behaviors are cigarette smoking, alcoholism, drug use, or unprotected sex. Problems can also be produced by lack of appropriate behavior such as sedentary lifestyle, not eating a healthy diet, not getting sufficient sleep or rest, or failing to take medications according to the physician’s orders.

 

Hence, promoting behavior change to healthy behaviors and eliminating unhealthy ones has the potential to markedly improve health. Mindfulness training has been shown to promote health and improve illness. It is well established that mindfulness can improve healthy behaviors. The research has been accumulating. So, it is reasonable to stop and summarize what has been learned.

 

In today’s Research News article “.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7647439/ ) Schuman-Olivier and colleagues review and summarize the published research studies on the ability of mindfulness training to promote behavior change and also the mechanism by which this is accomplished..

 

They summarize the research as demonstrating that mindfulness training improves self-regulation. This includes improvements in attention, cognitive control, emotion regulation, and self-related processes. These improvements in self-regulation results in an increased ability to change behavior from unhealthy behaviors to more healthy behaviors. This has been shown to be true with substance abuse, eating disorders, tobacco smoking, self-management with chronic diseases, violence, suicide, and self-harm.

 

They conclude that the published research supports the model that mindfulness training increases self-regulation which in turn supports behavior change.

Abstract

Initiating and maintaining behavior change is key to the prevention and treatment of most preventable chronic medical and psychiatric illnesses. The cultivation of mindfulness, involving acceptance and nonjudgment of present-moment experience, often results in transformative health behavior change. Neural systems involved in motivation and learning have an important role to play. A theoretical model of mindfulness that integrates these mechanisms with the cognitive, emotional, and self-related processes commonly described, while applying an integrated model to health behavior change, is needed. This integrative review (1) defines mindfulness and describes the mindfulness-based intervention movement, (2) synthesizes the neuroscience of mindfulness and integrates motivation and learning mechanisms within a mindful self-regulation model for understanding the complex effects of mindfulness on behavior change, and (3) synthesizes current clinical research evaluating the effects of mindfulness-based interventions targeting health behaviors relevant to psychiatric care. The review provides insight into the limitations of current research and proposes potential mechanisms to be tested in future research and targeted in clinical practice to enhance the impact of mindfulness on behavior change.

Mindfulness Training Alters the Brain to Improve Internally Oriented Attention

 

By John M. de Castro, Ph.D.

 

“Regular practice of mindfulness can help you grow a wiser, more connected, and stress-proof brain.” – Melanie Greenberg

 

There has accumulated a large amount of research demonstrating that meditation practice has significant benefits for psychological, physical, and spiritual wellbeing. One way that meditation practices may produce these benefits is by altering the brain. Meditation practice appears to mold and change the brain structures and connectivity, producing psychological, physical, and spiritual benefits, especially mindfulness.

 

Meditation practice results in a shift in mental processing. It produces a reduction of mind wandering and self-referential thinking and an increase in attention and higher-level thinking. The neural system that underlie mind wandering is termed the Default Mode Network (DMN) and consists in a set of brain structures including medial prefrontal cortex, posterior cingulate, lateral temporal cortex and the hippocampus. The neural system that underlies executive functions such as attention and higher-level thinking is termed the Central Executive Network (CEN) and includes the dorsolateral prefrontal cortex, posterior parietal cortex, and cingulate cortex. The salience network has been shown to direct attention to significant aspects of the environment. Hence the shift in thought process may well be associated with changes in the relationship of these systems.

 

The evidence of the effects of mindfulness practices on the Default Mode Network (DMN) and the Salience Network has been accumulating. So, it makes sense to summarize what has been learned. In today’s Research News article “Meta-analytic evidence that mindfulness training alters resting state default mode network connectivity.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9293892/ ) Rahrig and colleagues review, summarize, and perform a meta-analysis of the published research on the effects of mindfulness training on brain systems.

 

They identified 12 published research studies. They report that the research studies found that mindfulness training produced increased functional connectivity between the dorsal anterior cingulate cortex a component of the salience network and the posterior cingulate cortex a component of the default mode network. This suggests that mindfulness training increases the attention to significant aspects of internal processes. It can be hypothesized that this results in an internal attention to the internal mental processes of the mind.

Abstract

This meta-analysis sought to expand upon neurobiological models of mindfulness through investigation of inherent brain network connectivity outcomes, indexed via resting state functional connectivity (rsFC). We conducted a systematic review and meta-analysis of rsFC as an outcome of mindfulness training (MT) relative to control, with the hypothesis that MT would increase cross-network connectivity between nodes of the Default Mode Network (DMN), Salience Network (SN), and Frontoparietal Control Network (FPCN) as a mechanism of internally-oriented attentional control. Texts were identified from the databases: MEDLINE/PubMed, ERIC, PSYCINFO, ProQuest, Scopus, and Web of Sciences; and were screened for inclusion based on experimental/quasi-experimental trial design and use of mindfulness-based training interventions. RsFC effects were extracted from twelve studies (mindfulness n = 226; control n = 204). Voxel-based meta-analysis revealed significantly greater rsFC (MT > control) between the left middle cingulate (Hedge’s g = .234, p = 0.0288, I2 = 15.87), located within the SN, and the posterior cingulate cortex, a focal hub of the DMN. Egger’s test for publication bias was nonsignificant, bias = 2.17, p = 0.162. In support of our hypothesis, results suggest that MT targets internetwork (SN-DMN) connectivity implicated in the flexible control of internally-oriented attention.

Brief Mindfulness Training Improves the Willingness to Help Others.

 

By John M. de Castro, Ph.D.

 

“Never worry about numbers. Help one person at a time and always start with the person nearest you.” – Mother Teresa

 

Homo Sapiens is a very successful species. In part its success has been due to it being a very social species. Members of the species form groups beyond the family unit and work together for the common good. Members also take care of one another. We routinely give to charities which benefit people on the other side of the world. We donate our time as volunteers to build houses for the disadvantaged. We roll down our car windows and hand money to a homeless person on a street corner.  Mindfulness has been shown to increase altruistic behavior. But it is unclear how much training is sufficient to increase the likelihood of helping others.

 

In today’s Research News article “Short Mindfulness Meditation Increases Help-Giving Intention Towards a Stranger in Distress.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9386648/ ) Malin and Gumpel recruited undergraduate students and randomly assigned them to receive 2 30-minute sessions of mindfulness training, lectures on empathy and compassion, or listening to classical music. Before and after training they were measured for mindfulness, empathy, and emotional responses to a stranger in distress. After training they listened to an interview with a student struggling with a chronic illness. Afterwards they were asked if they’d be willing to volunteer to help students with chronic illnesses.

 

They found that after the mindfulness training there were significant increases in mindfulness and willingness to volunteer to help in comparison to the lecture and music groups. These results suggest that a brief mindfulness training is sufficient to increasing helping behavior. Mindfulness appears to increase altruism even with a brief training.

Abstract

Objectives

Mindfulness practice increases personal well-being, yet its effect on prosocial behaviors is not well-established. Initial studies suggest that an 8-week mindfulness program has a positive effect on help-giving towards a stranger in distress and that a short meditation promotes care towards an ostracized member. This research aims at examining whether a short mindfulness intervention promotes help-giving intention towards a stranger in distress and to understand the role of empathy in this effect.

Methods

A total of 210 undergraduate students were randomly assigned to two sessions of mindfulness practice, music, or lecture control conditions. Participants then listened to a sham interview with a student dealing with a chronic illness and were surveyed on their willingness to volunteer in an organization helping such students. Baseline dispositional empathy and consequent empathic care scales were completed to determine their effect.

Results

A significantly higher percentage of participants were willing to provide help in the mindfulness condition (50.8%), as compared to the music (31.2%) and the lecture (31%) conditions, χ2 (2, N = 189) = 9.51, p = .009. A significantly positive effect of dispositional empathy on empathic care was found in the mindfulness group (b = 1.40, SE = .31, p < .001), but not in the control groups.

Conclusions

This study showed that short mindfulness practice increases help-giving intention as compared to active control groups and moderates the association between dispositional empathy and empathic care. Future research including long-term follow-up will strengthen these findings.

Improve the Emotion Regulation of Midwives with Mindfulness

Improve the Emotion Regulation of Midwives with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindfulness is a way of befriending ourselves and our experience.” – Jon Kabat-Zinn

 

Mindfulness practice has been shown to improve emotion regulation. Practitioners demonstrate the ability to fully sense and experience emotions but respond to them in more appropriate and adaptive ways. In other words, mindful people are better able to experience yet control their responses to emotions. This is a very important consequence of mindfulness. Humans are very emotional creatures and these emotions can be very pleasant, providing the spice of life. But when they get extreme, they can produce misery and even mental illness. The ability of mindfulness training to improve emotion regulation is thought to be the basis for a wide variety of benefits that mindfulness provides to mental health and the treatment of mental illness especially depression and anxiety disorders.

 

In today’s Research News article “.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9103483/ ) Aghamohammadi and colleagues examined the effectiveness of mindfulness training on emotion regulation and perceived stress in Iranian midwives. The participants were randomly assigned either to a wait-list control condition or to receive an 8-week Mindfulness-Based Stress Reduction (MSBR) program modified for Iranian culture.

 

They report that mindfulness training significantly improved emotion regulation and self-efficacy and decreased perceived stress and hopelessness in the midwives. The improvements in emotion regulation included increases in acceptance of emotional responses, performance of goal-oriented behaviors in the face of a stressful situation, accessing emotional strategies, and improving emotional clarity.

 

These findings suggest that mindfulness training improves the ability to appreciate but control emotions producing improvements in mental health.

BMC Psychol. 2022 May 13;10(1):123. doi: 10.1186/s40359-022-00823-7. PMID: 35562792; PMCID: PMC9103483.

 

Abstract

Background

Midwives’ stress can have negative consequences on their emotional state, burnout, and poor quality of midwifery care. This study aimed to determine the effectiveness of an adapted mindfulness-based stress management program on perceived stress and the emotional regulation of midwives.

Methods

The study was a parallel randomized clinical trial on the midwives working in general hospitals of Zanjan, Iran. In this study, 121 midwives registered to participate based on the census sampling method were screened using a cut point of ≥ 28 in the Perceived Stress Scale (PSS). From the initial sample, 42 subjects had inclusion criteria assigned to two groups of control (n = 21) and intervention (n = 21) using online random allocation. The intervention group received an 8-week adapted mindfulness-based stress management program. This program emanates from the Kabat-Zinn’s MBSR program, which has been adjusted according to the Iranian culture. The ANCOVA and repeated measure analysis of variance test were used to compare groups over time.

Results

The results showed that the group intervention effectively affected perceived stress (P = 0.001) and difficulty in emotion regulation during the post-intervention period (P = 0.001). Moreover, the interventions were effective in emotion regulation (P = 0.003), but it was not effective on perceived stress (P = 0.125) at the 3-month follow-up.

Conclusions

This adapted mindfulness-based program successfully reduced stress and increased emotion regulation strategies in midwives; however, the long-term outcomes of this treatment program need further consideration.

Improve Mental Health with Mindfulness

Improve Mental Health with Mindfulness

 

By John M. de Castro, Ph.D.

 

“If you want to conquer the anxiety of life, live in the moment, live in the breath.” 
― Amit Ray

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of mental and physical illnesses. It appears to be beneficial across ages, from children to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. The breadth and depth of benefits is unprecedented. There is no other treatment or practice that has been shown to come anyway near the range of mindfulness’ positive benefits.

 

Over the last few decades, a vast amount of research has been published on the benefits of mindfulness practices on the mental and physical health of the practitioners. Most of these studies, however, utilize momentary (one-time) measures of mindfulness. A better method may be to measure mindfulness over a sustained period of time. Many studies have been performed using mindfulness measurement over time. So, it makes sense to step back and summarize what has been learned.

 

In today’s Research News article “Associations between mindfulness and mental health outcomes: A systematic review of ecological momentary assessment research.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9187214/ ) Enkema and colleagues

Review and summarize the published research studies on the benefits of mindfulness measured over time on mental health. They identified 22 published research studies.

 

They report that the published research found that mindfulness, measured over a sustained period of time, was associated with improved mental health. This included improvements in emotional awareness and positive emotions and decreases in negative emotions, anxiety, depression, rumination, cravings, and self-harm. Some indications were reported that measurement over sustained periods of time have greater reliability and validity.

 

“The way to live in the present is to remember that ‘This too shall pass.’ When you experience joy, remembering that ‘This too shall pass’ helps you savor the here and now. When you experience pain and sorrow, remembering that ‘This too shall pass’ reminds you that grief, like joy, is only temporary.” – Joey Green

Abstract

Objectives:

Psychological science has taken up investigations of the effectiveness of mindfulness-based programs (MBPs) and mechanisms through which people benefit from mindfulness. Reliable and valid psychometric tools are essential components of psychological science, and efforts have been made to produce tools for the accurate measurement of mindfulness as a construct. However, trait measurement methods, which are commonly used, may not adequately assess mindfulness and mental health outcomes in a way that allows for mechanisms to be adequately tested. Intensive longitudinal assessment methods sample behavior and experience multiple times over a brief period of several days or weeks, and may be more appropriate methods for testing mechanisms of action. We provide a systematic review of published, peer-reviewed studies that used intensive longitudinal methods to investigate the effects of mindfulness on mental health outcomes.

Methods:

Articles were included in the systematic review if mindfulness measures and/or mindfulness interventions were a part of the study design and if intensive longitudinal methods were used to assess mindfulness or mental health outcomes.

Results:

Findings consistently demonstrated a positive association between mindfulness and mental health. Only two studies collected both trait and state measurements of either mindfulness or mental health outcomes, and results indicated that EMA produced larger effect sizes between mindfulness and mental health outcomes.

Conclusions:

Theorized associations between mindfulness and mental health are supported by the current EMA literature. Intensive longitudinal methods may produce more consistent and reliable results through increased sensitivity and ecological validity in that they examine the momentary relationships between mindfulness and mental health outcomes. Thus, intensive longitudinal assessment may be a more appropriate method for investigating hypothesized mechanisms of action in MBPs.

Mindfulness is Associated with Lower Stigma and Improved Social Engagement in Breast Cancer Survivors

Mindfulness is Associated with Lower Stigma and Improved Social Engagement in Breast Cancer Survivors

 

By John M. de Castro, Ph.D.

 

“Cancer is a word, not a sentence.”- John Diamond

 

Because of great advances in treatment, many patients today are surviving cancer. But cancer survivors frequently suffer from anxiety, depression, mood disturbance, post-traumatic stress disorder (PTSD), sleep disturbance, fatigue, sexual dysfunction, loss of personal control, impaired quality of life, and psychiatric symptoms which have been found to persist even ten years after remission. Also, cancer survivors can have to deal with a heightened fear of reoccurrence.

 

Safe and effective treatments for the symptoms of cancer and the physical and psychological effects of the treatments are needed. Mindfulness training has been shown to help with general cancer recovery and mindfulness practices have been shown to improve the residual symptoms in cancer survivors. The mechanisms by which mindfulness may help cancer patients need to be explored.

 

Social engagement has positive benefits for cancer patients as they tend to improve the patient’s psychological well-being which, in turn, can reduce stress and the deleterious effects it has on the patient’s physical well-being. Unfortunately, there is a stigma around having cancer which can make the patient less likely to engage socially.

 

.In today’s Research News article “The mediator role of stigma in the association of mindfulness and social engagement among breast cancer survivors in China. Support Care Cancer.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8861258/ )  Jiang and colleagues demonstrate that mindfulness is associated with greater social engagement and also with the patients having lower beliefs about the stigma surrounding the disease and this helps to improve social engagement.

 

So, in part, mindfulness may improve cancer patients’ psychological well-being by reducing their beliefs about cancer stigma and improving social engagement.

Abstract

Purpose

This study aims to explore the association between mindfulness and social engagement among Chinese breast cancer survivors (BCSs) and the mediator role of stigma in the relation of mindfulness and social engagement.

Methods

This cross-sectional study was conducted among 937 BCSs from March to April 2021 in Shanghai, China. Data were collected using the Mindful Attention Awareness Scale, the Stigma Scale for Chronic Illness 8-item version, and the index of social engagement. Descriptive statistics, independent-sample t-test, one-way ANOVA, and regression analyses were used to explore the role of stigma in the association of mindfulness and social engagement among Chinese BCSs.

Results

Social engagement levels differed significantly by participant’s BMI, education level, employment status, personal monthly income, monthly per capita household income. Mindfulness was positively correlated with social engagement, and stigma was negatively correlated with mindfulness and social engagement among Chinese BCSs. Stigma plays a complete mediating role in the relationship between mindfulness and social engagement in BCSs.

Conclusion

In the practice of individual mindfulness intervention on social engagement of BCSs, health care providers should identify and eliminate the constraints, which restrain the reduction of stigma level while individual mindfulness is being enhanced.

Improve Chronic Fatigue Syndrome with Tai Chi

Improve Chronic Fatigue Syndrome with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai chi does not mean oriental wisdom or something exotic. It is the wisdom of your own senses, your own mind and body together as one process.” – Chungliang Al Huang

 

Myalgic encephalomyelitis/Chronic Fatigue Syndrome (CFS) occurs in about 0.2% of the population. It produces a profound, prolonged, and debilitating tiredness that is not corrected by rest. When severe, it can produce a chronic and extreme tiredness, so severe that sufferers can become bed-bound or need to use a wheel-chair. It produces muscle pain, brain fog and dizziness, poor memory, disturbed sleep and trouble with digestion.

 

Unfortunately, there are no known cures for CFS. The usual treatments for fatigue are targeted at symptom relief and include exercise and drugs. As an alternative to these traditional treatments, mindfulness training has been shown to reduce fatigue. Tai Chi is a mindfulness practice that includes movement and balance training. The ability of Tai Chi to improve Chronic Fatigue Syndrome (CFS) needs investigation.

 

In today’s Research News article “Altered Effective Connectivity of Resting-State Networks by Tai Chi Chuan in Chronic Fatigue Syndrome Patients: A Multivariate Granger Causality Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9203735/  ) Li and colleagues recruited adult patients with Chronic Fatigue Syndrome (CFS) and a group of healthy adults who had never practiced Tai Chi and provided them with 2 weekly 1 hour sessions of Tai Chi for 4 weeks. They were measured before and after training for health-related quality of life and had their brains scanned with Magnetic Resonance Imaging (MRI).

 

They found that in comparison to the healthy adults before Tai Chi the patients with Chronic Fatigue Syndrome (CFS) had significantly lower health-related quality of life and lower connectivity between the Sensorimotor Network (SMN) and the Default Mode Network (DMN). After Tai Chi training the patients with CFS had significant increases in health-related quality of life and improved connectivity between the SMN and DMN.

 

These findings demonstrate that Tai Chi practice can improve the symptoms of Chronic Fatigue Syndrome (CFS) potentially by strengthening connectivity in the brain. This is important as CFS is a mysterious disorder and these findings suggest that a lower level of brain connectivity may underlie the disorder. In addition, they show that Tai Chi practice may at least partially reverse these symptoms.

Abstract

Numerous evidence has shown that patients with chronic fatigue syndrome (CFS) have changes in resting brain functional connectivity, but there is no study on the brain network effect of Tai Chi Chuan intervention in CFS. To explore the influence of Tai Chi Chuan exercise on the causal relationship between brain functional networks in patients with CFS, 21 patients with CFS and 19 healthy controls were recruited for resting-state functional magnetic resonance imaging (rs-fMRI) scanning and 36-item Short-Form Health Survey (SF-36) scale assessment before and after 1month-long training in Tai Chi Chuan. We extracted the resting brain networks using the independent component analysis (ICA) method, analyzed the changes of FC in these networks, conducted Granger causality analysis (GCA) on it, and analyzed the correlation between the difference causality value and the SF-36 scale. Compared to the healthy control group, the SF-36 scale scores of patients with CFS were lower at baseline. Meanwhile, the causal relationship between sensorimotor network (SMN) and default mode network (DMN) was weakened. The above abnormalities could be improved by Tai Chi Chuan training for 1 month. In addition, the correlation analyses showed that the causal relationship between SMN and DMN was positively correlated with the scores of Role Physical (RP) and Bodily Pain (BP) in CFS patients, and the change of causal relationship between SMN and DMN before and after training was positively correlated with the change of BP score. The findings suggest that Tai Chi Chuan is helpful to improve the quality of life for patients with CFS. The change of Granger causality between SMN and DMN may be a readout parameter of CFS. Tai Chi Chuan may promote the functional plasticity of brain networks in patients with CFS by regulating the information transmission between them.
