Abstract

This research is motivated by students' low self-confidence, demonstrated by a lack of courage to express opinions, participation in learning, and social interaction in the classroom. Self-confidence is an important aspect of students' personal development, influencing their learning success and adjustment. This study aims to determine the difference in students' self-confidence levels before and after being given group guidance services using expressive writing techniques. This research used an experimental research design with a one-group pretest-posttest design. The sample consisted of 8 students selected using a purposive sampling technique. Based on the pretest and posttest data, the mean score before treatment was 74, which is considered low, and after treatment, it showed an increase with a mean score of 84. The paired t-test analysis obtained a significance value of 0.001 <0.05, indicating a significant difference in students' self-confidence levels before and after being given group guidance services using expressive writing techniques for 7 meetings. Thus, group guidance services using expressive writing techniques have proven effective in increasing the self-confidence of 10th-grade students at SMA Negeri 2 Samarinda.

Abstract

This research is motivated by the importance of self-concept, which is seen as the primary foundation for adolescent personal development. However, field observations indicate that not all adolescents are able to develop a positive self-concept. Therefore, this study aims to compare differences in adolescent self-concept levels before and after being treated with person-centered group counseling services using the expressive writing technique. The research was an experimental study using a one-group pretest-posttest design. A sample of six students was selected using purposive sampling. Based on pre-test and post-test data, the mean score before treatment was 85, which is considered low, and after treatment, it showed an increase with a mean score of 134.67. The paired t-test analysis obtained a significance value of 0.000 <0.05, indicating a difference in adolescent self-concept levels before and after being treated with the expressive writing technique for seven sessions. These results indicate that person-centered group counseling services using the expressive writing technique can improve adolescent self-concept.
