AbstractCognitive processing therapy (CPT) is effective for reducing posttraumatic stress disorder (PTSD) and depression among military veterans. However, studies have not examined whether CPT is associated with reductions in disability severity. The current study examines the association between disability severity and PTSD and depression among U.S. veterans who are receiving CPT. Veterans completed measures at pre- and posttreatment and received CPT through a Veterans Affairs PTSD outpatient (n = 155) or residential (n = 177) program. The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 was used to assess disability severity. The WHODAS 2.0 scores were positively correlated with clinician- and veteran-rated PTSD and veteran-rated depression at pre- and posttreatment (r = .22 to. 60). Compared with outpatients, veterans in residential treatment had worse scores on the WHODAS Mobility scale (ηp2 = .03), but on no other WHODAS 2.0 scales. Pre- to posttreatment reductions were found on all WHODAS 2.0 subscales (ηp2 = .03 to .15). Reductions in PTSD and depression were positively associated with improvements on the WHODAS 2.0 Summary scale and most subscales (r = .22 to. 52). Findings suggest that the WHODAS 2.0 is a promising disability severity measure for veterans in PTSD treatment. Findings also suggest that CPT may help veterans to achieve reductions in disability severity.Copyright © 2017 International Society for Traumatic Stress Studies.
