ABSTRACT
Presented herein is a comparative study of group treatments for posttraumatic stress disorder (PTSD). In this study, an emerging intervention, memory specificity training (MeST), was compared with cognitive processing therapy (CPT) using standardized outcome measures of target symptoms (i.e., anxiety and depression from client perspective; memory specificity from independent rater perspective) and global functioning (independent rater perspective), as well as a process measure of expectancy (client perspective). Clients were assessed on 3 separate occasions at baseline, posttreatment, and 3 months posttreatment. Adherence and treatment fidelity (independent rater perspective) were monitored throughout the course of both treatment conditions. Improvement in PTSD symptoms, depressive symptoms, and global functioning were similar between MeST and CPT; an increase in ability to specify memories upon retrieval was also similar between MeST and CPT. Positive reliable change was observed in both groups on all outcome measures. With respect to the primary target of PTSD symptoms, 88% of participants in both treatment groups moved into the functional distribution by posttreatment and maintained these gains at follow-up. Notably, compared with CPT, MeST required only half the dosage (i.e., number of sessions) to accomplish these gains. Illustrative vignettes from client-therapist exchanges are provided, and results are discussed in terms of the potential mechanisms of action. Implications for both clinical practice and clinical research are also included. (PsycINFO Database Record
