Therapist fidelity with an exposure-based treatment of ptsd in adults with schizophrenia or schizoaffective disorder

This study examined therapists’ fidelity to a manualized multi-component cognitive-behavioral intervention for posttraumatic stress disorder (PTSD), including exposure therapy, among public sector patients with a psychotic disorder. Therapists’ competence and adherence was assessed by clinicians at the master’s level or higher who rated 20% of randomly selected audiotaped sessions (n = 57 sessions, coded by two independent raters, with strong interrater agreement). Adherence ratings indicated that therapists complied well with the protocol, and competency ratings typically averaged above “very good” (6 on 7-point Likert scale). Findings suggest that therapists can effectively deliver a manualized cognitive-behavioral intervention for PTSD, with exposure therapy, to patients with severe mental illness without compromise to the structure of sessions and/or to the therapeutic relationship. These data add needed support for the implementation of cognitive-behavioral interventions, including exposure therapy, as effective treatments for PTSD in complicated patient populations such as those with severe forms of mental illness
