In 2019, approximately 301 million people worldwide lived with anxiety disorders, and
280 million people lived with depression. According to research conducted by the
Center for Reproductive Health et al. (2022), anxiety disorders (26.7%) are the most
prevalent mental health disorders experienced by adolescents, affecting both boys
(25.4%) and girls (28.2%) in Indonesia. This study aimed to determine the effectiveness
of classical music therapy in reducing anxiety among final-year public health students in
2023. The sample size for this research was 32 respondents. The research method used
was a quasi-experimental design employing a non-equivalent control group design, with
accidental sampling as the sampling technique. The pre-test and post-test results for the
control group showed a p-value of 0.232, which means it is more significant than 0.05,
indicating no effect. In contrast, the pre-test and post-test results for the experimental
group displayed a p-value of 0.027, which is less than 0.05, indicating a significant
impact. Thus, there was a difference in anxiety levels after applying classical music
therapy among final-year public health students facing their final projects at Indonesia
Maju University in 2023. In conclusion, classical music therapy is effective in reducing
anxiety. Therefore, classical music therapy is expected to be one of the alternative
methods for reducing stress, not only when completing final projects but also in other
situations.
