OBJECTIVE: This study explored possible mechanisms through which symptoms of posttraumatic stress disorder (PTSD) were reduced in a randomized controlled trial comparing the effect of a yoga intervention with an assessment control. METHOD: We examined whether changes in psychological flexibility, mindfulness, and emotion regulation strategies (expressive suppression and reappraisal) were associated with posttreatment PTSD symptoms for 38 women with Diagnostic and Statistical Manual of Mental Disorders Fourth Edition full or subthreshold PTSD. RESULTS: Hierarchical linear regression models revealed that expressive suppression significantly decreased for the yoga group relative to the assessment control. Psychological flexibility increased significantly for the control but not yoga group. However, increases in psychological flexibility were associated with decreases in PTSD symptoms for the yoga but not control group. CONCLUSION: Preliminary findings suggest that yoga may reduce expressive suppression and may improve PTSD symptoms by increasing psychological flexibility. More research is needed to replicate and extend these findings.

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.

OBJECTIVE: Eating-disordered behavior is prevalent among college women. Few interventions have successfully reduced risk factors for these behaviors, however. The most promising interventions are both selective and interactive. This study compared two newer types of interventions that meet these criteria: cognitive dissonance and yoga programs. METHOD: This study advertised programs for women who were dissatisfied with their bodies. Participants (N = 93) were randomly assigned to dissonance, yoga, or control groups. RESULTS: Hierarchical regression analyses revealed that there were no significant post-intervention differences between the yoga and control groups. Dissonance group participants had significantly lower scores than the scores of both other groups on measures of disordered eating, drive for thinness, body dissatisfaction, alexithymia, and anxiety. CONCLUSION: These findings have important implications for interventions on college campuses. In particular, dissonance interventions appear to be an efficient and inexpensive approach to reducing eating disorder risk factors. Additional research regarding the value of yoga interventions is needed.
