Main Article Content
Abstract
Depression is a major mental health issue among adolescents, which may lead to suicide. Finding approaches to treat thoughts and behaviors related to depression is a way to help reduce the problem and provide a pathway to return to normal life. This study is a quasi-experimental research aimed to comparing the average depression scores and self-esteem of high school students between an experimental group receiving a cognitive-behavioral therapy (CBT) program and a control group. The sample consisted of students with adolescent depression assessment scores ranging from 5 to 15 points, divided into 35 students in the experimental group and 35 in the control group. Data were collected using the Adolescent Depression Screening Tool (CES-D) and self-esteem was assessed with the Rosenberg Self-Esteem Scale (RSES). The CBT program consisted of 8 activities, each lasting 45 minutes, over 8 weeks, with a follow-up period of 4 weeks. The data were analyzed using inferential statistics, with Repeated Measures ANOVA at a significance level of 0.05. The research findings revealed that the average depression score in the experimental group differed significantly from the control group (p < 0.001).
The score in the experimental group was 6.51 points lower than the control group (95% CI: -7.86, -5.17), and at the follow-up stage, the experimental group's score was 9.06 points lower than the control group (95% CI: -10.42, -7.70). Additionally,
the average self-esteem score after participating in the program was significantly higher in the experimental group than in the control group (p = 0.030), with a 2.00 points difference (95% CI: 0.20, 3.80). Therefore, individuals interested in applying the CBT program should receive theoretical and practical training in cognitive-behavioral therapy techniques from specialists. Schools can adapt the CBT program to conduct activities for high school students with depression in other areas or incorporate CBT knowledge into their curriculum, tailored to the school’s context, to reduce depression problems among students.
