<![CDATA[Abstract. The rapid growth of TikTok social media usage has triggered the emergence of the toxic disinhibition online effect among young adults, raising critical concerns regarding psychological control mechanisms such as self-control. This study aims to bridge research gaps resulting from previous inconsistencies and to examine the contribution of self-control toward the toxic disinhibition online effect. This quantitative study utilized a cross-sectional design involving 110 active TikTok users selected through purposive sampling among Bandung Islamic University students aged 18–24 years. Data were collected using the Self-Control Scale and the Toxic Disinhibition Online Effect Scale. Simple linear regression analysis revealed a significant negative effect of self-control on the toxic disinhibition online effect (R Square = 0.528, p < 0.05). Dimension analysis indicated that non-impulsive actions serve as a strong predictor in mitigating destructive online behavior, while self-disclosure represents the most dominant manifestation of toxic disinhibition. In conclusion, robust self-regulation capacity significantly reduces destructive online tendencies. Abstrak.

Metode penelitian menggunakan pendekatan kuantitatif dengan analisis regresi linear sederhana. Teknik pengambilan sampel menggunakan purposive sampling dengan jumlah responden sebanyak 110 mahasiswa aktif Universitas Islam Bandung rentang usia 18–24 tahun.
