This study aimed to study the efficacy of a group behavioral activation treatment on decreased depression symptoms, cognitive-behavioral avoidance and increased quality of life. After meeting the study’s requirements, 40 students with depression were selected and randomly assigned to either behavioral activation treatment (n= 20) or a waiting list control group (n=20). The experimental group received eight weekly behavioral activation treatment sessions. The Beck Depression Inventory (BDI-II), Cognitive-Behavioral Avoidance (CBAD) and Quality of Life Questionnaire (WHOQOL-BREF) were used as outcome measures. The questionnaires were administered immediately before and after the intervention and two months following the termination of the intervention. The results of the study showed that behavioral activation treatment is effective in reducing symptoms of depression and cognitive-behavioral avoidance, however, there was no significant effect on participants’ quality of life. Based on the results of this study, group behavioral activation treatment is effective in decreasing symptoms, and cognitive-behavioral avoidance in students. These results can have practical implications for clinicians and counselors engaged in university counseling centers.
