Efektivitas Teknik Hipnokonseling untuk Meningkatkan Self Achievement dan Self Affiliation Siswa Di SMP Negeri 2 Indrajaya

Students’ achievement and affiliation are important aspects of academic and social development. This study aimed to examine the effectiveness of hypnocounseling in improving self-achievement and self-affiliation among junior high school students. A quantitative quasi-experimental study was conducted using a nonequivalent control group pretest-posttest design. Participants were 27 eighth-grade students selected through purposive sampling, comprising 13 students in the experimental group and 14 in the control group. The experimental group received hypnocounseling, whereas the control group received regular classroom guidance services. Data were analyzed using the Wilcoxon signed-rank test and the Mann–Whitney U test. The results showed that self-achievement scores in the experimental group increased by 12.85 points, while self-affiliation scores increased by 15.08 points. At posttest, the experimental group scored significantly higher than the control group on both variables, with large effect sizes. These findings provide preliminary evidence that hypnocounseling may be a useful alternative in school counseling to support students’ achievement and affiliation. However, the small sample and nonrandomized design limit causal interpretation and generalizability. Further research involving larger and more diverse samples, stronger experimental controls, and follow-up assessments is needed to establish the robustness and long-term sustainability of these outcomes.
