Posttraumatic stress disorder–related anhedonia as a predictor of psychosocial functional impairment among United States veterans

Prior research suggests that anhedonia symptoms related to posttraumatic stress disorder (PTSD; i.e., diminished interest, detachment from others, and difficulty experiencing positive emotions) are consistently associated with a higher degree of impairment in psychosocial functioning beyond that ass...

description Prior research suggests that anhedonia symptoms related to posttraumatic stress disorder (PTSD; i.e., diminished interest, detachment from others, and difficulty experiencing positive emotions) are consistently associated with a higher degree of impairment in psychosocial functioning beyond that associated with other PTSD symptoms. Unfortunately, much of this research has used cross‐sectional study designs; relied upon outdated DSM diagnostic criteria; and failed to control for potentially confounding variables, such as the presence of co‐occurring depression. This study used data from Waves 2 and 4 (n = 1,649) of the Veterans’ After‐Discharge Longitudinal Registry (Project VALOR), a longitudinal dataset of U.S. Army and Marine veterans. As measured using the Inventory of Psychosocial Functioning, Wave 4 psychosocial functioning was regressed on seven PTSD symptom factors at Wave 2 (i.e., intrusions, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal) and potential Wave 2 confounds. The Anhedonia factor, β = .123, most strongly predicted later psychosocial functional impairment beyond the impact of other PTSD symptom factors, βs = −.076–.046. Clinical implications of these findings are also discussed.
