Abstract
The present study aimed to examine the structural model of relationships between childhood trauma and rejection sensitivity with adolescents’ vulnerability to addiction, focusing on the mediating role of impulsivity. This research employed a descriptive-correlational design using structural equation modeling (SEM). The statistical population consisted of all high school students (second period) in the city of Osku during the 2023–2024 academic year (N = 4,667). A total of 465 students were selected through multistage cluster sampling. Data were collected using the Childhood Trauma Questionnaire, the Rejection Sensitivity Questionnaire, the Impulsivity Scale, and the Addiction Risk Identification Questionnaire. The data were analyzed through Pearson’s correlation coefficient and structural equation modeling using SPSS-21 and SmartPLS-3. The results indicated that the proposed model had a good fit. Childhood trauma and rejection sensitivity had a direct and significant effect on vulnerability to addiction (p < 0.05). Furthermore, childhood trauma exerted a significant indirect effect on vulnerability to addiction through the mediating role of impulsivity. Impulsivity also played a significant mediating role in the relationship between rejection sensitivity and vulnerability to addiction (p < 0.05). Childhood trauma and rejection sensitivity influence adolescents’ susceptibility to addiction both directly and indirectly through impulsivity. Therefore, addressing impulsivity in the context of childhood trauma and rejection sensitivity may play an important role in the prevention of adolescent addiction.
