The current study investigated changes in service members' cognitions over the course of Cognitive Processing Therapy (CPT) for posttraumatic stress disorder (PTSD). Sixty-three active duty service members with PTSD were drawn from 2 randomized controlled trials of CPT-Cognitive Only (CPT-C). Participants wrote an impact statement about the meaning of their index trauma at the beginning and again at the end of therapy. Clauses from each impact statement were qualitatively coded into three categories for analysis: assimilation, accommodation, and overaccommodation. The PTSD Checklist, Posttraumatic Symptom Scale-Interview Version, and the Beck Depression Inventory-II were administered at baseline and posttreatment. Repeated measures analyses documented a significant decrease in the percentage of assimilated or overaccommodated statements and an increase in the percentage of accommodated statements from the beginning to the end of treatment. Changes in accommodated statements over the course of treatment were negatively associated with PTSD and depression symptom severity, while statements indicative of overaccommodation were positively associated with both PTSD and depression symptom severity. Treatment responders had fewer overaccommodated and more accommodated statements. Findings suggest that CPT-C changes cognitions over the course of treatment. Methodological limitations and the lack of association between assimilation and PTSD symptom severity are further discussed.
The effectiveness and length of group-delivered cognitive treatment for Posttraumatic Stress Disorder (PTSD) was examined in a sample of women veterans. The sample included 271 primarily non-Hispanic white (61%) and Hispanic (25%) women veterans treated in 8-, 10-, or 12-group length sessions with manualized cognitive therapy for PTSD. Outcome was measured with the PTSD Symptom Checklist (PCL) in an intention-to-treat analysis (N = 271), in completer subjects (n = 172), and with group as the unit of analysis (n = 47 groups). Significant decreases in PTSD were found in the full sample (effect size [ES] range = 0.27 to 0.38), completers (ES range = 0.37 to 0.54), and group as the unit of analysis (ES range = 0.71 to 0.92), suggesting effectiveness of cognitive group treatment for PTSD. PCL scores significantly improved in the 8, 10, and 12 group lengths, with no differences between each. Clinical improvement showed a third decreasing 10 or more PCL points and 22% no longer meeting PTSD diagnostic criteria, with the best results in the 10-session group. The results suggest group-delivered cognitive therapy is an effective, efficient, time-limited treatment for PTSD.
Pragmatic trials testing the effectiveness of interventions under “real world” conditions help bridge the research-to-practice gap. Such trial designs are optimal for studying the impact of implementation efforts, such as the effectiveness of integrated behavioral health clinicians in primary care settings. Formal pragmatic trials conducted in integrated primary care settings are uncommon, making it difficult for researchers to anticipate the potential pitfalls associated with balancing scientific rigor with the demands of routine clinical practice. This paper is based on our experience conducting the first phase of a large, multisite, pragmatic clinical trial evaluating the implementation and effectiveness of behavioral health consultants treating patients with chronic pain using a manualized intervention, brief cognitive behavioral therapy for chronic pain (BCBT-CP). The paper highlights key choice points using the PRagmatic-Explanatory Continuum Indicator Summary (PRECIS-2) tool. We discuss the dilemmas of pragmatic research that we faced and offer recommendations for aspiring integrated primary care pragmatic trialists.
