Pengaruh Bimbingan Klasikal Terhadap Peningkatan Pengetahuan Dampak Sel-Harm Siswa di SMP Negeri 1 Jirak Jaya

Abstract

This study aims to determine the influence of classical guidance services on increasing students' knowledge about the impact of self-harm behavior in SMP Negeri 1 Jirak Jaya. The background of this study departs from the high cases of self-harm behavior among adolescents triggered by emotional pressure, lack of knowledge, and lack of educational space in the school environment. The method used is a pre-experimental design with a one group pretest-posttest model, which involves 36 students in grade VIII as a sample. The research instrument in the form of a self-harm impact knowledge questionnaire was given before and after the implementation of classical guidance services. The results showed an increase in the average knowledge score from 63.33 (pretest) to 69.86 (posttest). The Paired Sample T-Test yielded a significance value (Sig. 2tailed) < 0.001, indicating that the average difference was statistically significant. The correlation between pretest and posttest results reached 0.919, indicating a very strong and consistent relationship. These findings reinforce that classical tutoring services are effective in improving students' understanding of the physical, psychological, and social impacts of self-harm, while contributing to the formation of self-resilience and a mentally healthy school environment.
