Objective: Innovative approaches to the treatment of war-related posttraumatic stress disorder (PTSD) are needed. We report on secondary psychological outcomes of a randomized controlled trial of integrative exercise (IE) using aerobic and resistance exercise with mindfulness-based principles and yoga. We expected-in parallel to observed improvements in PTSD intensity and quality of life-improvements in mindfulness, interoceptive bodily awareness, and positive states of mind.
Method: A total of 47 war veterans with PTSD were randomized to 12-week IE versus waitlist. Changes in mindfulness, interoceptive awareness, and states of mind were assessed by self-report standard measures.
Results: Large effect sizes for the intervention were observed on Five-Facet Mindfulness Questionnaire Non-Reactivity (d = .85), Multidimensional Assessment of Interoceptive Awareness Body Listening (d = .80), and Self-Regulation (d = 1.05).
Conclusion: In a randomized controlled trial of a 12-week IE program for war veterans with PTSD, we saw significant improvements in mindfulness, interoceptive bodily awareness, and positive states of mind compared to a waitlist.
