The focus of this evaluation study is the Posttraumatic Stress Disorder Residential Treatment Curriculum [PTSD RTC]) to treat PTSD in female juvenile offenders. The overall purpose of the evaluation was to assess the implementation of the PTSD RTC at treatment facilities with female juvenile offenders and to evaluate the effect of the intervention on participants. The evaluation was designed to examine both process and outcome issues, including an examination of the implementation of the PTSD treatment groups, a curriculum review, and an assessment of treatment effectiveness. To investigate treatment effectiveness, the authors utilized a quasi-experimental design in which residential treatment facilities that chose to conduct PTSD RTC groups (treatment sites) were compared with residential treatment facilities that chose not to conduct PTSD RTC groups (comparison sites). The authors believe that the PTSD RTC is a strong curriculum with great potential. By addressing the issues that were revealed through this study, the PTSD project leaders will increase the likelihood that facilities will be able to implement the PTSD RTC as intended thereby allowing researchers to conduct the thorough evaluation that the program deserves. Appended are: (1) PTSD RTC Logic Model; (2) PTSD RTC Goals and Objectives; (3) Process Reports; (4) Consent Documents; and (5) Evaluation Instruments. (Contains 5 figures, 1 table, and 10 footnotes.)
