Prevalensi non-suicidal self-injury (NSSI) di kalangan dewasa muda dan efek sampingnya telah menjadi masalah yang memprihatinkan. Studi sebelumnya telah meneliti adanya korelasi antara NSSI, harga diri, dan teman sebaya yang menyakiti diri sendiri. Namun, pengujian hubungan antara tiga konstruksi secara keseluruhan cukup terbatas. Penelitian ini bertujuan untuk mengidentifikasi hubungan tersebut, dengan fokus pada peran harga diri sebagai moderator terhadap memiliki teman sebaya yang melukai diri sendiri dan NSSI. Dengan sampel 189 dewasa muda di Indonesia (dengan usia 18-24 tahun), data dikumpulkan melalui metode non-probability sampling menggunakan kuesioner daring. Dalam satu tahun terakhir, 71,96% peserta ditemukan pernah melukai dirinya sendiri setidaknya 1 kali, sementara 25,4% ditemukan pernah melakukan hal tersebut 5 kali atau lebih. Hasil penelitian juga menunjukkan korelasi signifikan antara harga diri dan NSSI (r = -.43), harga diri dan memiliki teman sebaya yang melukai diri sendiri (r = -.17), serta memiliki teman sebaya yang melukai diri sendiri dan NSSI (r = .25). Harga diri juga ditemukan memoderasi hubungan antara memiliki teman sebaya yang melukai diri sendiri dan NSSI (R2 = .0294; p < .05), sehingga hipotesis penelitian yang diajukan dapat diterima.

The prevalence of non-suicidal self-injury (NSSI) among young adults and its known adverse effects have become an issue of concern. Previous studies have examined the existence of correlations between NSSI, self-esteem, and self-injurious peers. Very limited studies, however, have been conducted to examine the relationship between the three constructs as a whole. The present study is aimed to identify the aforementioned relationship, focusing on the potential moderating role of self-esteem toward having self-injuring peers and NSSI. With a sample of 189 Indonesian young adults (18�24-year-olds), data was collected through a non-probability sampling method utilizing online questionnaires. Within the past year, 71.96% of participants were found to engage in self-injurious behavior at least once, while 25.4% were found to engage in said behavior 5 or more times. Results also showed significant correlations between self-esteem and NSSI (r = -.43), self-esteem and having self-injuring peers (r = -.17), as well as having self-injuring peers and NSSI (r = .25). Self-esteem was also found to moderate the relationship between having self-injuring peers and NSSI (R2 = .0294; p < .05), thus accepting the proposed study�s hypothesis.
