Abstract

Background: Many junior high school students exhibit low assertiveness, particularly in expressing opinions, resisting negative peer pressure, and maintaining interpersonal boundaries, which may hinder their socio-emotional development. Aim: This study examined the urgency and effectiveness of structured peer counseling as an intervention to improve assertive behavior among junior high school students. Method: The research employed a quasi-experimental pretest–posttest control-group design involving 62 students, divided into an experimental and a control group. The intervention consisted of structured peer counseling sessions emphasizing active listening, empathy, modeling, and role-playing of assertive communication. Assertive behavior was measured using a four-point Likert scale instrument administered before and after the intervention. Data were analyzed using the Wilcoxon Signed-Rank Test to determine differences between pretest and posttest scores. Results and Discussion: The findings revealed a statistically significant improvement in the experimental group (Z = -4.643, p < 0.001) with a large effect size (r = 0.60), indicating meaningful behavioral change following peer counseling. In contrast, the control group did not show a significant improvement (Z = -1.924, p = 0.054). These results suggest that structured peer counseling provides an effective developmental context for practicing assertive communication skills through peer interaction and social modeling. Conclusion: The study confirms the urgent need for assertive behavior intervention in junior high schools and demonstrates that structured peer counseling is an effective approach to enhancing students' assertiveness, providing empirical support for its integration into school guidance and counseling programs.

Abstract

Adolescence is a critical stage for self-concept development, yet many junior high school students experience low positive self-concept, influenced by academic pressure, peer comparison, and social expectations. This study developed and evaluated the Sambatan Peer Counseling Model, a culturally grounded, structured intervention designed to enhance positive self-concept among junior high school students in Madiun City, Indonesia. Using a research and development (RD) design, the model was developed based on humanistic principles and local cultural values of mutual cooperation. Feasibility, practicality, and effectiveness were assessed through expert validation, small-group trials, limited field testing, and a main operational trial involving 48 students divided into experimental and control groups. Data were collected using questionnaires, observations, and interviews, and analyzed using descriptive statistics and nonparametric tests. Results show that the model is feasible and practical, with high expert validation and implementation scores. Effectiveness testing revealed significant improvements in positive self-concept in the experimental group, while the control group showed no meaningful change. Qualitative observations further indicated increased participation, self-confidence, and positive social interaction. These findings suggest that the Sambatan Peer Counseling Model provides a holistic and culturally relevant approach to supporting adolescents’ cognitive, emotional, and social development. The study recommends adopting this model in school counseling programs and conducting further research to explore its broader applications and long-term effects.
