Abstract Introduction: Given the high prevalence and adverse consequences of high-risk behaviors among adolescents, this study aimed to examine the relationships among high-risk behaviors, anxiety sensitivity, and negative self-concept, specifically investigating the mediating role of experiential avoidance. Method: This study employed a descriptive-correlational design utilizing structural equation modeling (SEM). The study population comprised all high school students in Hamedan, Iran, during the 2022–2023 academic year. A sample of 327 students was selected via multistage cluster sampling. Data were collected using the Iranian Adolescents Risk-Taking Scale (Zadehmohammadi et al., 2011), the Multidimensional Experiential Avoidance Questionnaire (Gámez et al., 2011), the Anxiety Sensitivity Index (Reiss et al., 1986), and the Negative Self-Image Scale (Moscovitch & Huyder, 2011). Data analysis was conducted using Pearson correlation coefficients and SEM via SPSS 27 and AMOS 26 software. Results: Results indicated that high-risk behaviors were positively correlated with anxiety sensitivity (r = 0.27), negative self-concept (r = 0.25), and experiential avoidance (r = 0.52; p < 0.01). Furthermore, experiential avoidance was positively correlated with both anxiety sensitivity (r = 0.34) and negative self-concept (r = 0.37; p < 0.01). Bootstrap mediation analysis revealed that the indirect effects of anxiety sensitivity (β = 0.08, 95% CI [0.03, 0.15]) and negative self-concept (β = 0.08, 95% CI [0.03, 0.14]) on high-risk behaviors via experiential avoidance were statistically significant (p < 0.01). Conclusion: The findings indicate that experiential avoidance is a crucial mediating mechanism underlying the relationships of anxiety sensitivity and negative self-concept with high-risk behaviors in adolescents. Consequently, psychological interventions designed to prevent adolescent high-risk behaviors should specifically target the reduction of experiential avoidance, alongside anxiety sensitivity and negative self-concept. Targeting experiential avoidance within school-based programs may be particularly effective in mitigating these risks.
