Evaluation of a standardized posttraumatic stress disorder treatment framework in routine mental health care: Effectiveness and predictors of treatment outcome in a consecutive sample

AbstractThe primary aim of the present study was to evaluate the effectiveness of standardized care package (CP) treatment for posttraumatic stress disorder (PTSD) in a Danish sample of adult psychiatric outpatients (N = 948). Secondary aims were to identify baseline predictors of treatment outcomes and investigate between-group differences in outcomes with regard to sex and treatment modality (i.e., group vs. individual therapy). The naturalistic, nonrandomized study followed a pre–post design. Patient data from five psychiatric outpatient clinics were collected between March 2011 and November 2017. Data were drawn from self-report questionnaires (i.e., SCL-90-R, WHO-5, BHS) and therapist-reported measures (i.e., GAF-S, GAF-F) administered at baseline and posttreatment. Between-group effects for sex an d therapy modality (group vs. individual) were analyzed using analyses of variance, and possible predictors of outcomes were selected through LASSO regression and analyzed via hierarchical regression. Pre–post effects were small to moderate,ds  = 0.39 –0.69. No differences emerged regarding treatment modality, but women had significantly better outcomes than men. Aside from sex, only baseline symptom severity predicted outcomes. The effectiveness of the CP treatment was generally limited, indicating the need to implement improved therapeutic pr actices, such as the use of evidence-based treatments, and to provide better training to mental health clinicians. The findi...
