Direct and indirect effects of exercise on posttraumatic stress disorder symptoms: A longitudinal study.
General Hospital Psychiatry 2017 November
OBJECTIVE: Emerging evidence suggests that exercise may have beneficial effects on posttraumatic stress disorder (PTSD), and that this relationship may be indirectly affected by sleep, pain, and alcohol/substance use. The present study examined the longitudinal direct and indirect effects of exercise on PTSD symptoms.
METHOD: A national sample of 182 individuals, screening positive for PTSD, completed online assessments of PTSD symptoms, exercise behavior, psychological distress, sleep quality, and alcohol/substance use at baseline and three-month follow-up.
RESULTS: There were direct effects of strenuous intensity exercise on avoidance/numbing (b=-2.18, SE=1.12, p=0.05) and hyperarousal symptoms (b=-1.87, SE=0.82, p=0.03); and direct effects of total exercise on avoidance/numbing symptoms (b=-1.76, SE=0.94, p=0.05). Strenuous intensity exercise was indirectly associated with total PTSD symptoms (ab=-2.53, 95% CI: -5.72 to -0.38), avoidance/numbing (ab=-0.99, 95% CI: -2.43 to -0.05), and hyperarousal symptoms (ab=-0.78, 95% CI: -1.88 to -0.07) through sleep, while total exercise was indirectly associated with total PTSD symptoms through alcohol use (ab=0.32, 95% CI: 0.18-1.42).
CONCLUSION: Findings suggest that exercise has a complex, longitudinal, and beneficial association with PTSD symptoms. Future studies should continue to examine this relationship and any direct and indirect effects exercise may have on PTSD and its related conditions.
