|Official Title:||The Efficacy of Mindfulness-Based Stretching and Breathing Exercise as a Complementary Therapy for Posttraumatic Stress Disorder: A Prospective Randomized Study|
|Study Start Date :||October 2011|
|Primary Completion Date :||July 2012|
|Study Completion Date :||October 2012|
Experimental: Exercise Group
Participants who are screened positive for PTSD and participate in the series of 16 standardized, semiweekly 60-minute mindfulness-based exercise sessions. The intervention consists of stretching and balancing movements combined with breathing and a focus on mindfulness.Over the course of 8 weeks, the intensity of the exercise increases, but the sequence of the movements is the same.
Behavioral: Mindfulness-based exercise
8-week program of mindfulness-based stretching and breathing exercises
Other Name: Mindfulness stretching and breathing exercises
No Intervention: Control Group
Participants who are screened positive for PTSD but do not participate in the mindfulness-based exercise.
No Intervention: Base Group
Healthy volunteers who are not screened positive for PTSD and do not participate in the mindfulness-based exercise.
- Change From Baseline in PTSD Checklist - Civilian Version (PCL-C) Score [ Time Frame: Baseline and 8 weeks ]The PCL-C is a 17-item self-report instrument that measures the symptoms of PTSD. A total score, ranging from 17 to 85, is found by summing the scores of the 17 items. Higher values are considered to be a worse outcome. The inclusion criteria in the PTSD symptomatic group is a PCL-C total score of at least 28 with a score of 3 or higher on 1 or more items.To detect a reduction in PTSD symptom severity with a 2-sided 5% significance level and a power of 80%, the mean difference of PCL-C scores of 5.16 or greater requires a sample size of 20 participants for Exercise and Control groups, given an anticipated dropout rate of 10%. Data analyses are conducted using an a priori intention-to-treat approach. The analysis for the between-group differences of the intervention is conducted using t-tests comparing Exercise and Control groups at post-intervention. The analysis for the within-group difference is conducted using repeated measures ANOVA for both groups at baseline and week 8.
- Cortisol [ Time Frame: baseline and 8 weeks ]Change from baseline in serum cortisol levels at 8 weeks. Serum cortisol samples were collected at 8:00 Ante Meridian (AM). The changes are calculated from two time points as the values at 8 weeks minus the values at baseline.
