Abstract

Background: Adolescents are vulnerable to psychological distress due to rapid developmental changes and social pressures. School-based psychosocial strategies such as peer group support may enhance early mental-health promotion. Objective: To evaluate the effectiveness of peer group support on mental health indicators among junior high school students. Methods: A quasi-experimental pretest–posttest control group design was conducted among 84 adolescents aged 12–15 years at SMPN 4 Klari, Karawang Regency, Indonesia. The intervention group received 8 peer-support sessions across 8 weeks. Mental health was assessed using the Strengths and Difficulties Questionnaire (SDQ). Data were analyzed using paired and independent t-tests and ANCOVA. Results: The intervention significantly improved adaptive coping (+42.4%), reduced stress symptoms (−35.8%), and increased health-maintenance behaviors (+43.1%). Between-group post-intervention differences were statistically significant (p < .001). Effect size analysis indicated a large treatment impact (Cohen’s d > 0.8). Conclusion: Peer group support effectively enhances adolescent mental health and coping abilities. Integrating peer-based interventions into school programs is recommended to foster a supportive psychosocial environment.

Abstract

Adolescence often occurs in various environments, including school, peers, and family. The influence of peers and the school environment can make someone more vulnerable to trying smoking. If friends or role models in the family smoke, adolescents may feel more inclined to try smoking. The purpose of this article is to analyze the relationship between education using booklets and adolescents' knowledge about the health dangers of smoking at Santo Lukas High School, North Jakarta. This study used a quantitative design, conducted at a school in North Jakarta. The inclusion criteria were respondents aged 15-16 years and exclusion criteria were respondents who withdrew during the event. Demographic data used in this study included age and gender. The results obtained before the education using booklets, the majority were in the moderate category with a total of 18 students (75%), then after the education, there was an increase of 21 students (87.5%) in the highest category, with a p-value of 0.001 and a difference of 0.63. Providing health education using booklets has an effect on knowledge about the dangers of smoking.
