Abstract

This study examined the relationship between domains of quality of life and posttraumatic stress disorder (PTSD) symptoms in 319 male veterans in a randomized trial of group psychotherapy. Confirmatory factor analyses suggested a 4-factor model of quality of life (achievement, self-expression, relationships, and surroundings) fit better than a unidimensional model. Clinically meaningful symptom change was associated with greater change in all quality of life domains. At pretreatment, numbing symptoms uniquely predicted all quality of life domains. Change in avoidance and hyperarousal uniquely predicted change in achievement. Change in reexperiencing uniquely predicted change in self-expression. Change in numbing uniquely predicted change in relationships. Examining change in PTSD symptoms and quality of life domains may provide important information for treatment planning and evaluation.
