Posttraumatic stress disorder (PTSD) is a primary mental health concern of veterans. In clinical settings, efforts to improve broad facets beyond symptom amelioration and consideration of moderators of treatment effectiveness in this population are needed for continued improvement in care. General self-efficacy (GSE) has been indicated as a useful treatment target because of its association with positive outcomes such as increased positive health behaviors. Both race and educational attainment represent potential moderators of treatment response that are relevant for a veteran PTSD population. This study aimed to determine whether a PTSD Recovery Group Therapy Program resulted in improvement in GSE and whether racial and educational differences moderated GSE outcomes. Archival data were examined from male veterans (N = 450) receiving mental health services at a Veterans Affairs medical center using multilevel modeling to examine change in GSE over the course of treatment as well as moderation of change in GSE as a function of race and educational attainment. After completion of group therapy, results indicated there was significant improvement in GSE, with significantly different improvement based on education. Higher levels of education were associated with greater increases in GSE after treatment. Improvement in GSE did not differ by participant race. In clinical settings, efforts to increase GSE and attending to moderators such as educational attainment may be useful for improving PTSD treatment approaches.
