Impact of Musical Activities on the Social Skills of the Indonesian High School Students

Aims: This study aimed to determine the efficacy of musical activities and behavioral skills training strategies in group supervision in developing the social skills of high school pupils. Materials Methods: This randomized controlled study used a sample of high school pupils of Semarang City, Indonesia, in April 2022. The employed tool was a 106-item student social skills scale. The Gregory model’s content validity earned a score of 0.94, indicating strong validity. Cronbach’s alpha reliability test resulted in a score of 0.961. The Wilcoxon and the Mann-Whitney tests were used in SPSS 25 software. Findings: There was no significant difference between the pre-test social skills scores of the students in the experimental (326.69±27.15) and control (329.62±32.89) groups (p 0.05). Also, the social skills score of the experimental group (333.51±26.63) was not significantly higher than the control group (332.28±34.01) after the educational courses (p=0.517). Conclusion: Music activities do not improve high school students’ social skills.
