Presentation Type: Symposium
Little is known about posttraumatic stress disorder (PTSD) treatment outcomes among older adults. Although understudied, the veteran population is aging and research on the predictors of therapeutic success may maximize the efficiency and efficacy of interventions for this group. We examined the relationship between aspects of therapy engagement (i.e., homework completion, working alliance) and treatment outcomes in a group of male veterans (age > 60 years) with combat-related PTSD. Veterans (N = 87) were randomized to receive 12 weeks of prolonged exposure (PE) or relaxation therapy (RT). Participants were assessed at pre- and post-treatment and at 6-month follow-up. Therapeutic alliance was measured using the Working Alliance Inventory (WAI); homework completion was rated weekly with higher scores indicating better completion. Validated symptom scales were used to assess PTSD and anger. Homework completion, but not alliance, predicted change in PTSD (assessed by the Clinician-Administered PTSD Scale for DSM-5; CAPS-5) from pre- to post-treatment (β=-.47, p=.03), and higher CAPS scores at baseline predicted stronger therapeutic alliance (β=-.26, pβ=.28, p=.06). For the presentation, analyses will include follow-up data and an additional sample of older veterans and civilians who received CPT.
