Posttraumatic stress disorder (PTSD) is a chronic and debilitating disorder that affects the lives of 7-8% of adults in the U.S. Although several interventions demonstrate clinical effectiveness for treating PTSD, many patients continue to have residual symptoms and ask for a variety of treatment options. Complementary health approaches, such as meditation and yoga, hold promise for treating symptoms of PTSD. This meta-analysis evaluates the effect size (ES) of yoga and meditation on PTSD outcomes in adult patients. We also examined whether the intervention type, PTSD outcome measure, study population, sample size, or control condition moderated the effects of complementary approaches on PTSD outcomes. The studies included were 19 randomized control trials with data on 1,173 participants. A random effects model yielded a statistically significant ES in the small to medium range (ES = −.39, p < .001, 95% CI [−.57, −.22]). There were no appreciable differences between intervention types, study population, outcome measures, or control condition. There was, however, a marginally significant higher ES for sample size ≤ 30 (ES = −.78, k = 5). These findings suggest that meditation and yoga are promising complementary approaches in the treatment of PTSD among adults and warrant further study.
This study examined the effects of a Mindfulness-Based Stress Reduction (MBSR) program on psychological functioning and inflammatory biomarkers in women with histories of interpersonal trauma. The 8-week MBSR program was conducted at a community-based health center and participants (N = 50) completed several measures of psychological functioning at study entry as well as 4 weeks, 8 weeks, and 12 weeks later. Inflammatory biomarkers were assayed from blood collected at each assessment. A series of linear mixed model analyses were conducted to measure the effect of attendance and time on the dependent variables. Time was associated with significant decreases in perceived stress, depression, trait and state anxiety, emotion dysregulation, and post-traumatic stress symptoms as well as increases in mindfulness. Session attendance was associated with significant decreases in interleukin (IL)-6 levels. This pilot study demonstrated the potential beneficial effects of MBSR on psychological functioning and the inflammatory biomarker IL-6 among trauma-exposed and primarily low-income women. Decreases in inflammation have implications for this population, as interpersonal trauma can instigate chronic physiological dysregulation, heightened morbidity, and premature death. This study’s preliminary results support efforts to investigate biological remediation with behavioral interventions in vulnerable populations.
Practice of MBSR activities, particularly yoga, could provide benefits for specific aspects of physiologic function and positive affect. Changes in adaptive immunity in older adult MBSR practitioners warrant further study.
Objectives To examine the effects of age and depressive symptom severity on changes in positive affect among older adults randomly assigned to a Mindfulness-Based Stress Reduction (MBSR) program or a waitlist control group. Drawing from the Motivational Theory of Life-Span Development, we hypothesized that lower levels of depressive symptom severity and older age would be associated with greater positive affect in response to the MBSR intervention. Methods Data were collected from a sample of community-dwelling English-speaking adults (n = 200) aged ≥ 65, randomly assigned to an 8-week MBSR program or a Waitlist Control group. Our main outcome variable was a 5-item measure of positive affect, which was measured at study entry as well as 8 weeks and 6-months later. Results At 6-month follow-up, we observed group by baseline depressive symptom severity (β = −.17, p = .02) and group by baseline depressive symptom severity by age (β = −.14, p = .05) interactions. Among MBSR participants, greater baseline depressive symptom severity was also associated with less improvement in positive affect at the 6-month follow-up (β = −.30, p = .003). Findings were qualified by a significant depressive symptom severity by age interaction (β = −.25, p = .01), such that MBSR participants who were 70 and over with lower baseline depressive symptom severity had the greatest improvement in positive affect at the 6-month follow-up. Conclusion MBSR improves positive affect for older adults with lower depressive symptom severity, perhaps because it capitalizes on naturalistic changes in control strategies.
Indigenous aid workers carry out the majority of humanitarian aid work, yet there is little empirical information available on their support needs in different contexts. Focus groups (N = 26: Study 1) and a survey (N = 137; Study 2) were conducted with Guatemalan aid workers to explore their exposure to violence, posttraumatic stress symptoms, burnout, support needs, and motivators. Participants reported experiencing an average of 13 events of community violence and 17% reported symptoms consistent with posttraumatic stress disorder (PTSD). Direct community violence exposure and levels of emotional exhaustion were positively related to PTSD symptoms, while levels of personal accomplishment were inversely related to PTSD symptoms. Expressed support needs, motivators and rewards for aid work in the face of adversity are also reported as potential protective factors for further exploration. Implications for training and support of aid workers in similar contexts are also suggested.
Objectives: Mindfulness-based stress reduction (MBSR) is a promising intervention for older adults seeking to improve quality of life. More research is needed, however, to determine who is most willing to use the four techniques taught in the program (yoga, sitting meditation, informal meditation, and body scanning). This study evaluated the relationship between the Big Five personality dimensions (neuroticism, extraversion, openness to experience, conscientiousness, and agreeableness) and use of MBSR techniques both during the intervention and at a 6-month follow-up. The hypothesis was that those with higher levels of openness and agreeableness would be more likely to use the techniques. Methods: Participants were a community sample of 100 older adults who received an 8-week manualized MBSR intervention. Personality was assessed at baseline by using the 60-item NEO Five-Factor Inventory. Use of MBSR techniques was assessed through weekly practice logs during the intervention and a 6-month followup survey. Regression analyses were used to examine the association between each personality dimension and each indicator of MBSR use both during and after the intervention. Results: As hypothesized, openness and agreeableness predicted greater use of MBSR both during and after the intervention, while controlling for demographic differences in age, educational level, and sex. Openness was related to use of a variety of MBSR techniques during and after the intervention, while agreeableness was related to use of meditation techniques during the intervention. Mediation analysis suggested that personality explained postintervention MBSR use, both directly and by fostering initial uptake of MBSR during treatment. Conclusions: Personality dimensions accounted for individual differences in the use of MBSR techniques during and 6 months after the intervention. Future studies should consider how mental health practitioners would use these findings to target and tailor MBSR interventions to appeal to broader segments of the population.
Sleep disturbance is a significant public health issue that disproportionately affects survivors of interpersonal violence (IPV). This systematic review presents data on the relationship of IPV and sleep. Inclusion criteria for this review were studies that included subjects 18 years of age or older, used an IPV measure and sleep disturbance measure, and were published in a peer-reviewed journal in English. A total of 23 articles met full inclusion criteria and were included in the present review. Studies were largely cross sectional, were conducted in a wide range of clinical and nonclinical samples, and utilized a variety of measures to assess IPV (sexual violence, physical violence, or psychological aggression perpetrated by an intimate partner or sexual or physical violence by any perpetrator in childhood or adulthood) and sleep disturbances (both general sleep disturbance excluding specific sleep disorders and the two specific sleep disorders of insomnia and nightmares). The findings examined the prevalence and association of sleep disturbance in IPV samples from population and community studies, the prevalence and association of sleep disturbance in IPV studies, and the associations between post-traumatic stress disorder and sleep disturbance in IPV samples. All studies identified a relationship between IPV and sleep disturbance. The results of this review provide important information for clinicians, researchers, and policy makers on the prevalence of and relationship between IPV and sleep disturbance.
