The purpose of this study was to examine the effects of Adlerian E5 psychoeducational group counseling on university students’ authenticity and social interest. The study’s design was quasi-experimental, with pre- and posttest control groups. Participants in the experimental group participated in E5 group counseling, and the control group participants met weekly for open, experiential group-counseling sessions. The results indicated that participants in E5 groups reported significantly higher scores for all subscales and total scores of authenticity, but not for social interest. These findings provide the first empirical support for the impact of E5 group counseling. Implications for practice and future research are discussed.
