RESUMO
OBJECTIVE: There has been little evidence supporting the efficacy of psychoeducation as a stand-alone approach to alleviate posttraumatic stress disorder (PTSD). This study examined the efficacy of a stand-alone psychoeducation PTSD intervention using a group format that incorporated the option of bringing an emotional support person to sessions. METHOD: PTSD 102 is an eight-session, 1-hr, weekly intervention for veterans and their family members. Pre- and posttreatment symptom measurement data were analyzed from 101 veteran men and women seeking outpatient treatment in a PTSD Clinical Team clinic at a Veteran Health care outpatient facility. RESULTS: Paired-samples t tests were performed, which demonstrated a significant difference in the scores for pretreatment PTSD symptoms (M = 55.049, SD = 14.585) and posttreatment scores (M = 45.696, SD = 17.814); t(100) = 8.496, p < .001. The effect size was d = .843. Additionally, there was a significant difference in the scores for pretreatment depressive symptoms (M = 17.000, SD = 6.183) and posttreatment scores (M = 13.608, SD = 6.229); t(89) = 7.106, p < .001. The effect size was d = .749. CONCLUSIONS: Results from this study suggest that integrating emotional support individuals into a psychoeducational PTSD treatment group had a significant impact on mental health symptoms for veteran participants.

RESUMO
Longitudinal studies are commonly used in the social and behavioral sciences to answer a wide variety of research questions. Longitudinal researchers often collect data anonymously from participants when studying sensitive topics to ensure that accurate information is provided. One difficulty gathering longitudinal anonymous data is that of correctly matching participants across waves of data collection. A number of methods have been proposed for using nonidentifying codes to match anonymous participants; however, currently there is no consensus on the most effective method. This article reviews and analyzes the literature on nonidentifying codes and provides recommendations for researchers interested in using these types of codes in conducting anonymous longitudinal studies.
