Examining mechanisms of change in a yoga intervention for women: the influence of mindfulness, psychological flexibility, and emotion regulation on PTSD symptoms

Efficacy of yoga for posttraumatic stress disorder: A systematic review and meta-analysis of randomized controlled trials

Yoga is an increasingly popular complementary intervention to reduce posttraumatic stress disorder (PTSD) symptoms and related comorbidities, but its safety and treatment efficacy are not firmly established. We conducted a systematic review and meta-analysis of existing randomized control trials (RCTs) of yoga interventions for PTSD and related secondary outcomes (e.g., depression). Initial search results found over 668 potential papers. Twenty met inclusion criteria (e.g., RCTs on adult participants with PTSD that evaluated safety or efficacy outcomes). Meta-analysis indicated that, compared to control interventions, participation in yoga interventions significantly improved self-report PTSD (standardized mean difference [SMD]: -0.51; 95 % confidence interval [CI]: -0.68, -0.35) and immediate (SMD: -0.39; 95 % CI: -0.56, -0.22) and long-term (SMD: -0.44; 95 % CI: -0.74, -0.13) depression symptoms. However, using clinician-reported assessments, yoga interventions were not associated with improved PTSD symptoms. Type of yoga differentially predicted outcomes. Sensitivity analysis showed consistent effect sizes when omitting each study from main analyses. Six studies reported whether any serious adverse events occurred. None were indicated. No publication bias was found, although individual intervention studies tended to be high in bias. Results suggest yoga is likely a safe and effective complementary intervention for reducing PTSD and depressive symptoms in individuals with PTSD. More rigorous RCTs are warranted.

Moving out of your mind and into your body: Yoga buffers the effects of childhood maltreatment on PTSD symptoms

Objective: Childhood maltreatment has been consistently linked to posttraumatic stress disorder (PTSD) symptoms among college students and yoga may buffer the effects. The current study examined the frequency of college student's yoga practice over the past year as a moderator of childhood maltreatment and PTSD symptoms in the past 30 days. Participants: A sample of 177 college students from a southern university. Methods: Participants competed an online survey in exchange for extra credit or entry into a gift card raffle. Results: Moderation analysis indicated that a more frequent yoga practice buffered the relationship between maltreatment and PTSD symptoms. Conclusion: Clinicians working with college students with a history of maltreatment are encouraged to make referrals to yoga classes. Universities are encouraged to adopt trauma-sensitive yoga programs.

Trauma of the Shared Environment: A Qualitative Analysis of the Experiences of Survivors of College Campus Sexual Assault

Survivors of campus sexual assault are often tasked with healing while sharing an environment with their perpetrators. However, little is known about the effects of a shared environment on survivor well-being. A qualitative thematic analysis design was employed to address this gap. We conducted semi-structured interviews with nine female survivors who identified their perpetrators as fellow students at a large state university in the southeastern U.S. The five themes that emerged are situated within an ecological framework, which is also used to guide our recommendations for supporting survivors' well-being within higher education.

Flexibility and inflexibility in an Iranian sample: psychometric properties of MPFI based on the Hexaflex model

OBJECTIVES

Acceptance and Commitment Therapy (ACT) emphasizes the importance of psychological flexibility in promoting emotional, psychological, and social well-being, while also acknowledging rigidity as a precursor to psychological disorders. Analyzing the psychometric qualities based on the multidimensional Hexaflex model is critical for determining the efficiency of therapeutic interventions. Thus, the purpose of this study is to investigate the psychometric features of the Multidimensional Psychological Flexibility Inventory (MPFI) within the context of the Hexaflex model in a group of Iranian university students.

METHODS

Exploratory and confirmatory factor analyses were used in this study to evaluate the psychometric features of the flexibility/inflexibility scale (MPFI) in a sample of Iranian university students.

FINDINGS

In the exploratory factor analysis involving a sample of 300 students, six factors were identified for flexibility and six for inflexibility (56.3% males and 43.7% females). In the confirmatory factor analysis with a sample of 388 participants, the results validated 60 items across a total of six flexibility and inflexibility factors. This outcome can serve as a robust estimate for flexibility, inflexibility, the second-order model, and the final model. Cronbach's alpha values for various components, including acceptance, present-moment awareness (or contact with the present moment), self as context, cognitive defusing, values, committed action, total flexibility, experiential avoidance, lack of present-moment awareness, self as content, fusion, lack of contact with values, inaction, and total inflexibility, were reported as follows: 0.818, 0.869, 0.862, 0.904, 0.935, 0.935, 0.942, 0.895, 0.839, 0.883, 0.904, 0.912, 0.941, and 0.941, respectively.

CONCLUSIONS

The Farsi version of the MPFI for university students has great psychometric qualities, making it a reliable assessment instrument for the ACT.

Yoga as an adjunct treatment for the eating disorders: A qualitive enquiry of clinician perspectives

BACKGROUND

Yoga has been recognised as a beneficial adjunct for eating disorder (ED) treatment due to demonstrating positive effects on ED symptomology. Despite this, research exploring the perspectives of clinicians regarding the use of yoga for the spectrum of the EDs is limited. Consequently, this study utilised qualitative enquiry to explore the experiences and perspectives of clinicians regarding the implementation of yoga as an adjunct for ED treatment. This research examines how yoga may be safely applied for the EDs, to enhance ED treatment approaches and recovery.

METHODS

This study employed semi-structured interviews with 12-clincians with up to 20-years of experience working therapeutically with people with EDs. Participants were asked their perspectives on the benefits, risks, and adaptations for delivering safe and suitable yoga programs for the spectrum of EDs. Template thematic analysis was used.

RESULTS

Four distinct themes were identified. They included the (1) benefits of yoga, (2) risks associated with the practice, (3) recommendations for adapting yoga for this cohort, and (4) implementing yoga alongside current psychological treatment.

CONCLUSIONS

Clinicians viewed yoga as a safe and suitable transdiagnostic treatment, with the potential to support individuals with a more holistic and sustained recovery model. Clinicians raised concerns that might arise with the use of yoga for this cohort, however, they also emphasised the ability for these to be mitigated with a series of key adaptations. Importantly, clinicians recommended that yoga is implemented and monitored alongside ED treatment to ensure its suitability and safety. Key barriers for implementing yoga as an adjunct treatment and future research directions are discussed. Recent research has explored the benefits of yoga for individuals with eating disorders (EDs). However, researchers have not yet interviewed clinicians who work with those with EDs regarding their views on using yoga for their clients. This study therefore interviewed 12 clinicians working with individuals with EDs, to obtain their views for using yoga as a therapeutic treatment for this group. Overall, clinicians viewed yoga as a safe and beneficial treatment for EDs. While some concerns were raised regarding the safety of yoga for this group, clinicians emphasised that these could be relieved by a series of key adaptations. This study offers unique insights into how yoga may be safely applied into the care for ED clients, to enhance their treatment approaches and recovery.

A Systematic Review of Quantitative and Qualitative Results of Randomized Controlled Trials Assessing the Effect of Yoga in Adult Women With Post-traumatic Stress Disorder: What Is Known So Far

Yoga has been increasingly practiced in recent years, with many of its practitioners being female. Adults may seek a complementary and alternative medicine (CAM) modality, such as yoga, to attempt to alleviate symptoms related to mental health conditions such as post-traumatic stress disorder (PTSD). Our goal for this systematic review was to collect and analyze all available data from quantitative and qualitative reports of randomized controlled trials (RCTs) conducted over the past 10 years on the impact of yoga on women diagnosed with PTSD. We included RCTs with the adult female population in which yoga was practiced for more than one week. We searched the databases PubMed, PubMed Central (PMC), and MEDLINE on June 11, 2022, Embase on June 12, 2022, and Science Direct on June 13, 2022, to find relevant articles. With the Cochrane RoB2 tool and Critical Appraisal Skills Programme (CASP) criteria, we checked for their quality, after which we selected 13 high-quality reports comprising seven original study designs and a total of 496 women. Of the 13 reports, nine evaluated effectiveness, four assessed feasibility, three explored acceptability, and four identified qualitative themes. We compared the results based on the assessed themes. Our results found yoga effective, feasible, acceptable, and a viable interoceptive pathway for emotional and personal growth. Limitations in our study include insufficient papers with large sample sizes and not including papers other than RCTs. With our research, we hope to present healthcare providers with research-based data on the effects of yoga so that they may better navigate its role in therapy as the trend of seeing more patients taking an interest in such alternative approaches rises.

Management of post-traumatic stress disorder symptoms by yoga: an overview

BACKGROUND

Posttraumatic stress disorder (PTSD) can occur after trauma. While PTSD management strategies include first-line pharmacotherapy and psychotherapy, mind-body therapies, such as yoga, are applied in the PTSD population. This overview aimed to summarize the effectiveness of yoga interventions on PTSD symptoms in adults in a systematic review (SR) including randomized controlled trials (RCTs).

METHOD

We searched for SR with or without meta-analysis of RCTs involving adults with PTSD diagnosis or trauma history. The search was conducted until April 2022, through six databases (Cochrane Database, MEDLINE (Pubmed), Scopus, Embase, CINHAL and PEDro). The primary outcome was the evolution of PTSD symptoms throughout the intervention. Secondary outcomes included follow-up, safety, adherence, and cost of the intervention. Two authors independently performed the selection, data extraction and risk of bias assessment with the AMSTAR 2 tool and overlap calculation. This overview is a qualitative summary of the results obtained in the selected studies.

RESULTS

Eleven SRs were analyzed, of which 8 included meta-analyses. The overlap between studies was considered very high (corrected covered area of 21%). Fifty-nine RCTs involving 4434 participants were included. Yoga had a significant small-to-moderate effect-size on PTSD symptom decrease in 7 SRs and non-significant effects in 1 SR with meta-analysis. All SR without meta-analysis found beneficial effects of yoga on PTSD. Secondary outcomes were not sufficiently assessed to provide clear evidence. Results should be interpreted with caution as 1 SR was rated as at moderate risk of bias, 3 as low and 7 as critically low.

CONCLUSIONS

While yoga therapy seems promising for decreasing PTSD symptoms, future research should standardize yoga therapy duration/frequency/type and consider long-term efficacy to better delineate yoga therapy efficacy in PTSD patients.

Preschool teachers' psychological wellbeing, emotion regulation, and emotional responsiveness: a US-Korea comparison

Introduction

Psychological wellbeing is an essential indicator of early care and education (ECE) teachers' positive practices across countries. Moreover, previous studies suggest that teachers' wellbeing and practice may be indirectly associated via emotion regulation. However, teachers in various contexts demonstrate different patterns of psychological wellbeing, emotion regulation, and emotional responsiveness, and the ways these factors associate with each other also vary.

Methods

The current study investigates whether the indirect associations between ECE teachers' psychological wellbeing (i.e., emotional exhaustion, job-related competence, and personal stress) and their responsiveness toward children's emotions via emotion regulation (i.e., reappraisal and suppression) appear differently in two national contexts, the United States (US) and South Korea (SK). Multi-group path analysis was conducted to compare the mediation models between US teachers (n = 1,129) and SK teachers (n = 322).

Results

We found significant indirect associations among wellbeing, emotion regulation, and responsiveness in both countries. However, significant associations were more prominent among SK teachers, and the patterns of indirect associations had substantial cross-country differences. Furthermore, the roles of reappraisal and suppression emotion regulation found to be different among ECE teachers in SK and US.

Discussion

The cross-country variations in the associations among wellbeing, emotion regulation, and responsiveness suggest that differential policy efforts and intervention strategies are needed for ECE teachers in the US and SK.

"I put a stone on my heart and kept going": An explanatory model of how distress is generated and regulated among Indian women from slums reporting gender-based violence

Clinical variation in the expression of panic disorder, depression and anxiety, and posttraumatic stress disorder (PTSD) has have been documented across cultures. However, local (emic) cultural models that explain how people make sense of their illness experiences remain relatively understudied in India among trauma-exposed populations. Further, the integration of emic findings into clinical care is limited, underscoring the need for emic perspectives following trauma to improve the development or adaptation of trauma-focused treatments in India. This study describes an emic explanatory model of distress, which includes idioms of distress, perceived causes of distress, and coping/help-seeking behaviors among Indian women from slums reporting gender-based violence. This explanatory model can be used as a culturally grounded way to develop clinical case conceptualizations to adapt and deliver psychological treatments for this under-served population.

A pragmatic preference trial of therapeutic yoga as an adjunct to group cognitive behaviour therapy versus group CBT alone for depression and anxiety

BACKGROUND

Yoga has several mechanisms that make it a promising treatment for depression and anxiety, including physical activity, behavioural activation, and mindfulness. Following positive outcomes from adapted CBT interventions incorporating mindfulness-based practices, this study explored the effects of a therapeutic yoga program as an adjunct to group-based CBT for depression or anxiety.

METHODS

This was a pragmatic preference trial involving adults diagnosed with depression or anxiety in a regional primary mental healthcare service (n = 59), comparing transdiagnostic group CBT (n = 27) with transdiagnostic group CBT combined with an adjunct therapeutic yoga program (n = 32). A preference recruitment design allowed eligible participants (n = 35) to self-select into the adjunct program. The Depression Anxiety Stress Scale-21 (DASS) was assessed at baseline, post-intervention, and three-months follow up.

RESULTS

CBT + Yoga was an acceptable alternative to CBT alone. Significant reductions were observed in total DASS scores and the 3 subscales of the DASS for both groups, however CBT + Yoga showed significantly lower depressive and anxiety symptoms post-intervention, compared to CBT alone. CBT + Yoga also showed sustained reductions in depressive symptoms over three-months, and more rapid reductions in depressive symptoms, compared to CBT alone.

LIMITATIONS

These findings should be considered preliminary due to the moderate sample size, with a rigorous randomised control trial necessary to definitively support the integration of yoga within mental health care to augment the benefits and uptake of transdiagnostic CBT for depression and anxiety.

CONCLUSIONS

Complementing other mindfulness-based practices, therapeutic yoga shows promise as an adjunct to transdiagnostic CBT.

Integration of hatha yoga and evidence-based psychological treatments for common mental disorders: An evidence map

BACKGROUND

Interest in the use of yoga to enhance engagement with and augment the benefits of psychological treatment has grown. However, a systematic approach to reviewing existing research examining the use of yoga with psychological treatment is lacking.

MATERIALS AND METHODS

This mapping review identified and synthesised research trialling yoga as an integrated or adjunct therapy with evidence-based psychological interventions for the treatment of anxiety, depression, PTSD, and eating disorders.

RESULTS

Overall, the review identified ten published and three unpublished studies, representing either single group or small quasi-experimental research designs.

DISCUSSION

Limited but promising findings were shown for yoga with CBT for anxiety and depression, and the integration of yoga within intensive treatment models for PTSD.

CONCLUSIONS

Future research is encouraged to focus on controlled trials that enable examination of the component effect of yoga when applied with evidence-based psychological treatment and acceptability and feasibility data to further knowledge regarding a role for yoga in clinical practice.

Mind–Body Exercises for PTSD Symptoms, Depression, and Anxiety in Patients With PTSD: A Systematic Review and Meta-Analysis

Objectives

This study aims to systematically analyze the effects of mind–body exercises on post-traumatic stress disorder (PTSD) symptoms, depression, and anxiety in patients with PTSD. Furthermore, it intends to provide scientific evidence-based exercise prescriptions.

Methods

Chinese (i.e., China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, and Wanfang) and English (i.e., Web of Science, PubMed, the Cochrane Library, and EMBASE) databases were used as data sources to search for studies on the effects of mind–body exercises on symptoms associated with patients with PTSD from January 1980 to November 2020. After a rigorous screening, 16 eligible randomized controlled trials (RCTs) were included in the meta-analysis.

Results

Mind–body exercises exerted a significant effect on PTSD symptoms [standard mean difference (SMD) = −0.41, 95% confidence interval (CI) −0.64 to −0.19, p < 0.001], depression (SMD = −0.35, 95% CI: −0.55 to −0.15, p < 0.001), and anxiety (SMD = −0.31, 95% CI: −0.74 to −0.12, p < 0.001) among patients with PTSD. Subgroup analysis demonstrated that 60–150 min per session for 8–16 weeks of mindfulness was more effective in improving symptoms in patients with PTSD under 45 years of age compared with other subgroups. For depression, 150–180 min of yoga exercises once per week was effective. For anxiety, the frequency, timing, duration, and type of mind–body exercises that are most effective in relieving anxiety in patients with PTSD cannot be determined at this time due to the limited number of eligible RCTs.

Conclusions

Mind–body exercises were found to be significantly effective in improving PTSD symptoms, depression, and anxiety in patients with PTSD. Therefore, they can be used as an adjunct to intervention for symptoms of patients with PTSD. However, this conclusion requires further confirmation through additional scientific and objective RCTs.

Program evaluation of trauma-informed yoga for vulnerable populations

BACKGROUND

Trauma is highly prevalent among vulnerable populations, including those who are incarcerated, in treatment for substance use, or seeking mental health services. Trauma-informed yoga seeks to create a safer yoga practice for individuals with a trauma history and may improve emotional and physical wellbeing. Thus, we conducted an evaluation of a trauma-informed yoga program to gain insight into participant experiences.

METHODS

Trauma-informed yoga classes were led by trained volunteers and held in three sectors that work with vulnerable populations: corrections and reentry, substance use treatment and recovery, and community and mental health. Data were collected via anonymous survey using a retrospective pre-post design. The survey instrument captured reasons for student participation and perceived effects of yoga on emotional and physical wellbeing.

RESULTS

Students were motivated to participate in yoga classes by expectations of physical, mental, and spiritual benefit. Students reported perceived improvements in emotional and physical wellbeing and greater use of self-regulation skills after starting yoga.

CONCLUSION

Our findings suggest trauma-informed yoga is perceived as beneficial by vulnerable individuals, especially those in the correctional system or recovering from substance use. Our results support the value of offering trauma-informed yoga in institutionalized and community settings. Improvements in emotional and physical wellbeing warrant formal study.

Psychological Flexibility Is Key for Reducing the Severity and Impact of Fibromyalgia

Fibromyalgia has a significant impact on the lives of patients; symptoms are influenced by psychological factors, such as psychological flexibility and catastrophizing. The objective of this study was to determine the importance of these variables in moderating the association between the severity and impact of fibromyalgia symptoms. A total of 187 patients from a general hospital population were evaluated using the Combined Index of Severity of Fibromyalgia (ICAF), the Fibromyalgia Impact Questionnaire (FIQ), the Acceptance and Action Questionnaire-II (AAQ-II), and the Pain Catastrophizing Scale (PCS). A series of multiple regression analyses were carried out using the PROCESS macro and decision tree analysis. The results show that psychological flexibility modulates the relation between severity and the impact of fibromyalgia symptoms. Catastrophism has residual importance and depends on the interaction with psychological flexibility. Interaction occurs if the severity of the disease is in transition from a mild to a moderate level and accounts for 40.1% of the variance in the sample. These aspects should be considered for evaluation and early intervention in fibromyalgia patients.

A randomized controlled trial of yoga vs nonaerobic exercise for veterans with PTSD: Understanding efficacy, mechanisms of change, and mode of delivery

BACKGROUND AND OBJECTIVES

Posttraumatic stress disorder (PTSD) is a chronic, disabling, and prevalent mental health disorder among Veterans. Despite the availability of empirically supported psychotherapies, many Veterans remain symptomatic after treatment and/or prefer to seek complementary and integrative health approaches, including yoga, to manage PTSD. The randomized controlled trial (RCT) described herein will evaluate the efficacy of a manualized yoga program as compared to nonaerobic exercise in reducing PTSD severity among Veterans. A secondary aim of this study is to better understand the mechanisms of change.

METHODS

Veterans (N = 192) with PTSD will be randomized to hatha yoga or nonaerobic physical activity control; both groups consist of 12 weekly, 60-min group or online training sessions with 15-20 min of daily at-home practice. Outcome measures will be administered at baseline, mid-treatment, posttreatment, and 12-week follow-up.

PROJECTED OUTCOMES

This study will evaluate changes in PTSD severity (primary outcome) as well as depression, anxiety, anger, sleep problems, and psychosocial disability (secondary outcomes). We will also use multiple mediation to examine two potential models of the mechanisms of clinical effect: the Attention Model (i.e., yoga increases attentional control, which reduces PTSD symptoms), the Coping Model (i.e., yoga increases distress tolerance, which improves coping, which reduces PTSD symptoms), and the combination of these models. This aspect of the study is innovative and important given the absence of an existing, comprehensive model for understanding yoga's impact on PTSD. Ultimately, we hope to develop guidelines for application of yoga to PTSD recovery.

Mindful attention awareness and cognitive defusion are indirectly associated with less PTSD-like symptoms via reduced maladaptive posttraumatic cognitions and avoidance coping

Recently, the effects of mindfulness-based interventions for posttraumatic stress disorder (PTSD) have been studied. However, we lack knowledge of the processes or mechanisms through which mindfulness influences resilience or promotes recovery following exposure to trauma. In this study, we examine the process by which mindfulness and cognitive-behavioral factors such as posttraumatic negative cognition and avoidance behaviors are associated with reduced PTSD-like symptoms. A questionnaire survey was conducted with 885 university students, using the Trauma Experience Questionnaire, Mindful Attention Awareness Scale, Cognitive Fusion Questionnaire, Post-Traumatic Stress Disorder Checklist, revised Ways of Coping Checklist, and a brief version of the Posttraumatic Cognitions Inventory. Data from 254 participants who experienced trauma with PTSD-like symptoms were analyzed. The final model using SEM indicated no direct association of mindful attention awareness on PTSD-like symptoms, a small direct association of cognitive defusion on PTSD-like symptoms, and a large indirect association mediated by posttraumatic negative cognitions and avoidance coping. Owing to the study’s cross-sectional design, strong conclusions cannot be drawn regarding the causal relationship of mindfulness and cognitive-behavioral factors or generalizations. However, our findings suggest that it would be worthwhile to continue to clarify the mechanism of mindfulness and to investigate its use in the treatment of PTSD. In the future, a highly accurate study design will hopefully be used to examine the mechanisms of several different factors associated with improvement in posttraumatic stress symptoms, preferably including them in the same model.

How does yoga reduce stress? A clinical trial testing psychological mechanisms

Yoga interventions can reduce stress, but the mechanisms underlying that stress reduction remain largely unidentified. Understanding how yoga works is essential to optimizing interventions. The present study tested five potential psychosocial mechanisms (increased mindfulness, interoceptive awareness, spiritual well-being, self-compassion and self-control) that have been proposed to explain yoga's impact on stress. Forty-two participants (62% female; 64% White) in a yoga program for stress reduction completed surveys at baseline (T1), mid-intervention (T2) and post-intervention (12 weeks; T3). We measured two aspects of stress, perceived stress and stress reactivity. Changes were assessed with paired t-tests; associations between changes in mechanisms were tested in residual change models. Only stress reactivity decreased, on average, from T1 to T3. Except for self-compassion, all psychosocial mechanisms increased from T1 to T3, with minimal changes from T2 to T3. Except for self-control, increases in each mechanism were strongly associated with decreases in both measures of stress between T1 and T2 and decreases in perceived stress from T1 to T3 (all p's < 0.05). Increased psychosocial resources are associated with stress reduction. Yoga interventions targeting these resources may show stronger stress reduction effects. Future research should test these linkages more rigorously using active comparison groups and larger samples.

Psychological inflexibility mediates the relationship between fear of negative evaluation and psychological vulnerability

College students worldwide and in Turkey face many biopsychosocial spiritual and economic issues, in part due to developmental and contextual factors. Understanding these issues and their relationship with psychological inflexibility, which is the central concept to the Acceptance and Commitment Therapy (ACT), is an unexplored gap in the literature. Therefore, the aim of the present study is to examine the mediating and moderating roles of Psychological Inflexibility (PI) in the relationship between Fear of Negative Evaluation (FNE) and Psychological Vulnerability (PV), and to set an empirical ground for developing evidence-based research and practices based on ACT. The study group consisted of 389 undergraduate students studying in various departments of a mid-sized urban state university. Regression-based mediation and moderation testing procedures revealed that PI partially mediates the relationship between FNE and PV. Moderating role of PI on the same relationship was not verified. The present findings are deemed to be useful for understanding the relationships of these constructs and developing future mental health research and interventions to address biopsychosocial spiritual issues and enhance wellbeing especially from an ACT perspective.

Online yoga to reduce post traumatic stress in women who have experienced stillbirth: a randomized control feasibility trial

BACKGROUND

About 1 in every 150 pregnancies end in stillbirth. Consequences include symptoms of post traumatic stress disorder (PTSD), depression, and anxiety. Yoga has been used to treat PTSD in other populations and may improve health outcomes for stillbirth mothers. The purpose of this study was to determine: (a) feasibility of a 12-week home-based, online yoga intervention with varying doses; (b) acceptability of a "stretch and tone" control group; and (c) preliminary efficacy of the intervention on reducing symptoms of PTSD, anxiety, depression, perinatal grief, self-compassion, emotional regulation, mindfulness, sleep quality, and subjective health.

METHODS

Participants (N = 90) were recruited nationally and randomized into one of three groups for yoga or exercise (low dose (LD), 60 min per week; moderate dose (MD), 150 min per week; and stretch-and-tone control group (STC)). Baseline and post-intervention surveys measured main outcomes (listed above). Frequency analyses were used to determine feasibility. Repeated measures ANCOVA were used to determine preliminary efficacy. Multiple regression analyses were used to determine a dose-response relationship between minutes of yoga and each outcome variable.

RESULTS

Over half of participants completed the intervention (n = 48/90). Benchmarks (≥70% reported > 75% satisfaction) were met in each group for satisfaction and enjoyment. Participants meeting benchmarks (completing > 90% of prescribed minutes 9/12 weeks) for LD and MD groups were 44% (n = 8/18) and 6% (n = 1/16), respectively. LD and MD groups averaged 44.0 and 77.3 min per week of yoga, respectively. The MD group reported that 150 prescribed minutes per week of yoga was too much. There were significant decreases in PTSD and depression, and improvements in self-rated health at post-intervention for both intervention groups. There was a significant difference in depression scores (p = .036) and grief intensity (p = .009) between the MD and STC groups. PTSD showed non-significant decreases of 43% and 56% at post-intervention in LD and MD groups, respectively (22% decrease in control).

CONCLUSIONS

This was the first study to determine the feasibility and preliminary efficacy of an online yoga intervention for women after stillbirth. Future research warrants a randomized controlled trial.

Coronavirus Stress, Optimism-Pessimism, Psychological Inflexibility, and Psychological Health: Psychometric Properties of the Coronavirus Stress Measure

The coronavirus (COVID-19) pandemic is currently a global health threat attributed to negatively affecting the mental health and well-being of people globally. The purpose of the present study is to examine the mediating role of optimism-pessimism and psychological inflexibility in the relationship of coronavirus stress with psychological problems among Turkish adults. The sample of the study included 451 adults (55% women). Participants mainly consisted of young adults with a mean age of 23.30 years, ranging from 18 to 65 years (SD = 6.97). A mediation model indicated that coronavirus stress had a significant predictive effect on optimism-pessimism, psychological inflexibility, and psychological problems. Further, optimism-pessimism and psychological inflexibility mediated the effect of coronavirus stress on psychological problems in adults. Lastly, optimism-pessimism predicted the psychological problems of adults through psychological inflexibility. These results elucidate our understanding of the role of mediators in coronavirus stress and psychological health problems. The findings are useful in terms of providing evidence for tailoring interventions and implementing preventative approaches to mitigate the psychopathological consequences of COVID-19. Based on the present findings, the potential utility of acceptance and commitment therapy is discussed within the context of COVID-19.

Exploring how different types of yoga change psychological resources and emotional well-being across a single session

OBJECTIVES

Yoga demonstrates beneficial effects in many populations, yet our understanding of how yoga brings about these effects is quite limited. Among the proposed mechanisms of yoga are increasing psychological resources (mindfulness, body consciousness, self-transcendence, spiritual peace, and social connectedness) that may bring about salutary effects on emotional wellbeing. Further, yoga is a complex practice comprising meditation, active and restorative postures, and breathwork; however little is known about how different components may affect mechanisms. We aimed to determine how an acute session of yoga (and its specific components) related to pre- to post- session changes in proposed mechanisms (psychological resources) and whether those changes were associated with positive changes in emotions.

DESIGN

144 regular yoga practitioners completed measures of mindfulness, body consciousness, self-transcendence, social connectedness, spiritual peace, and exercise-induced emotions (positive engagement, revitalization, tranquility, exhaustion) immediately before and after a yoga session (N = 11 sessions, each a different type of yoga). Perceived properties of each yoga session, exercise exertion and engagement with the yoga teacher were assessed immediately following the session.

RESULTS

Pre-to post- yoga, levels of positive emotions (engagement, tranquility and revitalization) increased while exhaustion decreased. Further, all psychological resources increased and closely tracked improved emotions. Additionally, aspects of the yoga session correlated with changes in psychological resources (mechanisms) and emotions.

CONCLUSIONS

Yoga may influence multiple psychological mechanisms that influence emotional well-being. Further, different types of yoga may affect different mechanisms. Results can inform yoga interventions aiming to optimize effects through specific mechanisms such as mindfulness or spirituality.

Social Support Versus Emotion Regulation: Mediators of Attachment and Psychological Problems After Social Exclusion

Introduction: Secure parental attachment improves the perception of available social support and the socialization of emotion regulation strategies. Research has suggested that both perceived social support and emotion regulation help individuals reappraise stressful situations as less stressful. Individuals under stress are at an increased risk for psychological problems.

Method: The current study examined whether social support, emotion regulation, and psychological inflexibility mediated the relation between parental attachment and psychological problems after a social exclusion task.

Results: Results indicated that secure parental attachment was associated with an increased ability to up-regulate emotions and with an increase in the perception of available social support. Secure attachment to either parent was indirectly associated with psychological problems reported after social exclusion.

Discussion: Indirect effects were found only for pathways from attachment through emotion regulation strategies, which suggests that emotion regulation may be a driving factor between attachment to parental figures and stress induced psychological problems. Further results, limitations, and implications were discussed.

Use of Meditation and Cognitive Behavioral Therapies for the Treatment of Stress, Depression and Anxiety in Students. A Systematic Review and Meta-Analysis

The prevalence of mental health problems within students due to high academic demands and learning difficulties is a current challenge the field of education. The aim of this study is to review the scientific literature in order to analyze the effect produced by cognitive-behavioral programs and meditation strategies on stress, anxiety, and depression in students. A further aim is to identify the determinants of treatment success. The bibliographic search was carried out using Web of Science, specifically in the categories of "Education and Educational Research" and "Psychology", obtaining a sample of 122 articles published between 2007 and 2018. Studies were included which had a pre-experimental or quasi-experimental design and included pre-test and post-test phases. Following application of inclusion criteria, 34 articles were selected for inclusion in a meta-analysis of the random effects of each variable. This obtained an average effect size of -0.41 for stress, -0.37 for anxiety, and -0.30 for depression. Three moderating variables were analyzed, with significant correlations being found for the type of treatment relating to stress (Q = 11.01, df = 2, p = 0.004, R2 = 0.294) and depression (Q = 6.14, df = 2, p = 0.048; R2 = 0.436). The stage of education of the individuals was also found to impact upon anxiety intervention success (Q = 13.093 df = 2, p = 0.0009, R2 = 0.196). Interventions mainly addressed the importance of meditation strategies, mindfulness programs, and cognitive-behavioral therapy to reduce stress, anxiety, and depression in students. This supports the need to increase research at an early age, considering the treatment of mental health as a key factor influencing academic performance and quality of life.

Regulate yourself: Emotion regulation and protective behavioral strategies in substance use behaviors

Although research suggests links between emotion regulation strategies and substance use outcomes, little work has examined the relationship between specific strategies (i.e., reappraisal and suppression) and outcomes (i.e., alcohol and cannabis consumption and related problems). To date, no research has examined the association between emotion regulation strategies and protective behavioral strategies used while engaging in substance use. Thus, the current study examined these relations for females and males. Undergraduates (N = 643) completed an online battery of self-report measures. Using structural equation modeling, results indicated improved Emotion Regulation Questionnaire model fit after one item was removed. Reappraisal was negatively associated with alcohol binge frequency and related problems for females, though suppression was negatively related to these outcomes for males. Reappraisal was also negatively associated with cannabis-related problems for males only. Reappraisal was positively associated with all types of protective behavioral strategies use for females, whereas only alcohol-specific serious harm reduction and cannabis protective behavioral strategies were significant for males. Latent variable interactions between reappraisal and protective behavioral strategies were significant for past-month cannabis use and related problems for males and indicated protective behavioral strategies use was more protective against past-month use and cannabis-related problems for those high in reappraisal. Although replication is necessary, these preliminary findings suggest the link between emotion regulation strategies and substance use outcomes among college students is complex and future work may benefit from examining these relations from an emotion regulation flexibility perspective.

For Body and Mind: Practicing Yoga and Emotion Regulation

The purpose of the present study was to examine if the length of yoga training may influence the use of cognitive reappraisal and expressive suppression (as emotion regulation strategies) and whether this relationship may be moderated by personality traits. Based on previous studies, we hypothesized that the link between the length of yoga practice and emotion regulation can rely most heavily on participants’ conscientiousness and extraversion levels. Ninety women in two groups participated in the study: those who have been practicing yoga for over a year and those who have been practicing for a shorter period of time. An Emotion Regulation Questionnaire was applied to measure the use the strategies of cognitive reappraisal and expressive suppression. Moreover, personality traits, based on the Big Five model were assessed. The results of the study provided support for our prediction: participants who engaged in yoga practice for a longer period of time (as compared to participants who practiced yoga for a shorter duration), reported using cognitive reappraisal more often. Furthermore, longer yoga practice was more beneficial than shorter practice especially for individuals with low levels of conscientiousness and extraversion. Thus, extraversion and conscientiousness seem to facilitate the process of drawing benefits from practicing yoga.

Individual differences in emotion regulation moderate the associations between empathy and affective distress

Individual differences in empathy can have positive and negative psychological outcomes. Yet, individual differences in the processing and regulation of empathy-induced emotion have not been fully explored within this dynamic. This study was designed to explore whether individual differences in emotion regulation strategies moderated the effects of empathy on common forms of affective distress. Eight hundred and forty four participants completed survey measures of trait empathy, emotion regulation strategies, and symptoms of depression, anxiety, and stress. Affective empathy typically predicted greater affective distress, but the effects on depression and anxiety were offset when people were effective at reappraising their emotions. Cognitive empathy predicted lower distress on average, but this beneficial effect on anxiety and stress was absent in those who typically suppressed their emotions. Finally, suppression unexpectedly reduced the depression and stress reported for people high in affective empathy. Individual differences in emotion regulation are an important moderator between empathy and psychological health, and thus a useful target for intervention.

Group interventions to reduce emotional distress and fatigue in breast cancer patients: a 9-month follow-up pragmatic trial

Background:

Long-term effects of psychosocial interventions to reduce emotional distress, sleep difficulties, and fatigue of breast cancer patients are rarely examined. We aim to assess the effectiveness of three group interventions, based on cognitive behavioural therapy (CBT), yoga, and self-hypnosis, in comparison to a control group at a 9-month follow-up.

Methods:

A total of 123 patients chose to participate in one of the interventions. A control group was set up for those who agreed not to participate. Emotional distress, fatigue, and sleep quality were assessed before (T0) and after interventions (T1), and at 3-month (T2) and 9-month follow-ups (T3).

Results:

Nine months after interventions, there was a decrease of anxiety (P=0.000), depression (P=0.000), and fatigue (P=0.002) in the hypnosis group, and a decrease of anxiety (P=0.024) in the yoga group. There were no significant improvements for all the investigated variables in the CBT and control groups.

Conclusions:

Our results showed that mind–body interventions seem to be an interesting psychological approach to improve the well-being of breast cancer patients. Further research is needed to improve the understanding of the mechanisms of action of such interventions and their long-term effects on quality of life.

Evaluation of a specialized yoga program for persons with a spinal cord injury: a pilot randomized controlled trial

Objectives

The purpose of this randomized controlled trial was to evaluate the effects of a specialized yoga program for individuals with a spinal cord injury (SCI) on pain, psychological, and mindfulness variables.

Materials and methods

Participants with SCI (n=23) were outpatients or community members affiliated with a rehabilitation hospital. Participants were randomized to an Iyengar yoga (IY; n=11) group or to a 6-week wait-list control (WLC; n=12) group. The IY group participated in a twice-weekly 6-week seated IY program; the WLC group participated in the same yoga program, after the IY group’s yoga program had ended. Pain, psychological, and mindfulness measures were collected at two time points for both groups (within 1–2 weeks before and after program 1 and at a third time point for the WLC group (within 1 week after program 2).

Results

Linear mixed-effect growth models were conducted to evaluate the main effects of group at T2 (postintervention), controlling for T1 (preintervention) scores. T2 depression scores were lower (F_1,18=6.1, P<0.05) and T2 self-compassion scores higher (F_1,18=6.57, P< 0.05) in the IY group compared to the WLC group. To increase sample size and power, the two groups were combined and analyzed across time by comparing pre- and postintervention scores. Main effects of time were found for depression scores, (F_1,14.83=6.62, P<0.05), self-compassion, (F_1,16.6=4.49, P<0.05), mindfulness (F_1,16.79=5.42, P<0.05), mindful observing (F_1,19.82=5.06, P<0.05), and mindful nonreactivity, (F_1,16.53=4.92, P<0.05), all showing improvement after the intervention.

Discussion

The results indicated that a specialized 6-week yoga intervention reduced depressive symptoms and increased self-compassion in individuals with SCI, and may also have fostered greater mindfulness.

Improving physical and mental health in frontline mental health care providers: Yoga-based stress management versus cognitive behavioral stress management

The need for brief, low-cost, easily disseminable and effective interventions to promote healthy lifestyles is high. This is especially true for mental health providers. We developed two studies to compare the impacts of Cognitive Behavioral Stress Management (CBSM) and Yoga Based Stress Management (YBSM) interventions for healthcare professionals. Study 1 offered an 8-week YBSM intervention to 37 mental healthcare participants and collected health data pre and post. Study 2 offered YBSM and CBSM classes to 40 randomly assigned mental healthcare providers and collected mental and physical health data at four time points. In Study 1, using t-tests, the YBSM intervention affected a number of mental and physical wellbeing indices pre to post. In Study 2, using linear mixed modeling, both YBSM and CBSM groups improved significantly (p <.05) in fruit and vegetable intake, heart rate, alcohol consumption, relaxation and awareness, professional quality of life, compassion satisfaction, burnout, depression, and stress levels. There was a group by time effect for coping confidence (CBSM increased more, p<.05, F = 4.34), physical activity (YBSM increased more, p<.05, F = 3.47), overall mental health (YBSM increased more, p<.10, F =5.32), and secondary traumatic stress (YBSM decreased more, p<.10, F = 4.89). YBSM and CBSM appear to be useful for healthcare professionals' mental and physical health. YBSM demonstrates some benefit above and beyond the extremely well-studied and empirically supported CBSM, including increased physical activity, overall mental health, and decreased secondary traumatic stress benefits.

Trauma Sensitive Yoga as a complementary treatment for posttraumatic stress disorder: A Qualitative Descriptive analysis

Research on Posttraumatic Stress Disorder and chronic childhood abuse has revealed that traditional trauma treatments often fail to fully address the complicated symptom presentation, including the somatic complaints, loss of awareness of one's emotional and physical being in the present moment, and overall lack of integration between the self and the body. The mindfulness-based intervention of hatha yoga shows promise as a complementary treatment, and focuses on personal growth in addition to symptom reduction. This qualitative study explored the experiences of thirty-one adult women with PTSD related to chronic childhood trauma who participated in a 10-week Trauma Sensitive Yoga class, specifically examining perceived changes in symptoms and personal growth. Five themes were identified that reflect participants' feelings of Gratitude and compassion, Relatedness, Acceptance, Centeredness, and Empowerment. Results and implications for research and clinical work are presented.

Relaxation Techniques for Trauma

Physiological symptoms of posttraumatic stress disorder (PTSD) manifest as increased arousal and reactivity seen as anger outburst, irritability, reckless behavior with no concern for consequences, hypervigilance, sleep disturbance, and problems with focus (American Psychiatric Association, 2013 ). In seeking the most beneficial treatment for PTSD, consideration must be given to the anxiety response. Relaxation techniques are shown to help address the physiological manifestations of prolonged stress. The techniques addressed by the authors in this article include mindfulness, deep breathing, yoga, and meditation. By utilizing these techniques traditional therapies can be complemented. In addition, those who are averse to the traditional evidence-based practices or for those who have tried traditional therapies without success; these alternative interventions may assist in lessening physiological manifestations of PTSD. Future research studies assessing the benefits of these treatment modalities are warranted to provide empirical evidence to support the efficacy of these treatments.

The Efficacy of Body-Oriented Yoga in Mental Disorders–A Systematic Review and Meta-Analysis

BACKGROUND

The efficacy of body-oriented yoga in the treatment of mental disorders has been investigated in numerous studies. This article is a systematic review and meta-analysis of the relevant publications.

METHODS

All studies in which the efficacy of hatha-yoga, i.e., body-oriented yoga with asanas and pranayama, was studied in adult patients suffering from a mental disorder (as diagnosed by ICD or DSM criteria) were included in the analysis. The primary endpoint was disorder-specific symptom severity. The publications were identified by a systematic search in the PubMed, Web of Science, PsycINFO and ProQuest databases, supplemented by a search with the Google Scholar search engine and a manual search in the reference lists of meta-analyses and primary studies, as well as in specialized journals.

RESULTS

25 studies with a total of 1339 patients were included in the analysis. A large and significant effect of yoga was seen with respect to the primary endpoint (symptom severity) (Hedges' g = 0.91; 95% confidence interval [0.55; 1.28]; number needed to treat [NNT]: 2.03), with substantial heterogeneity (I2 = 69.8%) compared to untreated control groups. Small but significant effects of yoga were also seen in comparison with attention control (g = 0.39; [0.04; 0.73]; NNT: 4.55) and physical exercise (g = 0.30; [0.01; 0.59]; NNT: 5.75); no difference in efficacy was found between yoga and standard psychotherapy (g = 0.08; [-0.24; 0,40]; NNT: 21.89). In view of the relatively high risk of bias, these findings should be interpreted with caution.

CONCLUSION

Body-oriented yoga with asanas and pranayama as central components is a promising complementary treatment for mental disorders and should be investigated in further high-quality studies.

Impact of a Yoga Intervention on Physical Activity, Self-Efficacy, and Motivation in Women with PTSD Symptoms

BACKGROUND

Studies using yoga have demonstrated initial efficacy for treating symptoms across anxiety disorders, including posttraumatic stress disorder.

OBJECTIVE

Understanding how interventions influence participants' physical activity and what determinants affect continued physical activity behavior change is important because maintenance of the behavior may be critical to continued mental health gains and symptom reduction.

METHODS

This study investigated change in physical activity and possible psychological mechanisms of physical activity behavior change, including self-efficacy and regulatory motivation, in a randomized controlled trial of yoga for women with post-traumatic stress disorder symptoms (n=38).

RESULTS

Growth curve modeling results showed no significant changes in physical activity or self-efficacy for either group, whereas external motivation decreased significantly in the yoga group but not in the control group.

CONCLUSIONS

Investigators of future yoga interventions may want to focus on increasing self-efficacy and internal regulatory motivation, so that physical activity and resultant symptom relief can be maintained.
