The present study aimed to assess the predictive power of familial emotional climate, difficulties in emotion regulation, and distress tolerance concerning the likelihood of addiction among university students.</span></span></span><br> <span style="line-height:normal"><span style="unicode-bidi:embed"><b><span lang="FR">Materials and Methods: </span></b><span lang="FR">Employing a descriptive correlational design, this research investigated a sample of 168 students from Islamic Azad University, Ahvaz (Iran), selected via convenience sampling. Data on addiction potential, family emotional climate, emotion regulation difficulties, and distress tolerance were gathered using the established scales. Subsequent analysis involved descriptive statistics, Pearson correlations, and stepwise regression to explore the relationships between these variables among the university student population.<span style="font-family:"Myriad Pro",sans-serif"></span></span></span></span><br> <span style="line-height:normal"><span style="unicode-bidi:embed"><b><span lang="FR">Results:</span></b><span lang="FR"> This study examined the relationship of familial emotional climate, difficulties in emotion regulation, and distress tolerance with addiction propensity among university students. Significant correlations were observed: a negative association between familial emotional climate and addiction propensity (r=&minus;0.59; P<0.001), a positive association between difficulties in emotion regulation and addiction propensity (r=0.50; P<0.001), and a negative association between distress tolerance and addiction propensity (r=&minus;0.49; P<0.001). Stepwise regression analysis revealed that familial emotional climate explained 34% of the variance in addiction propensity. The addition of difficulties in emotion regulation increased the explained variance to 47%, and the subsequent inclusion of distress tolerance further accounted for 49% of the variance.</span></span></span><br> <b><span lang="FR"><span style="line-height:110%">Conclusion:</span></span></b><span lang="FR"><span style="line-height:110%"> This study robustly demonstrated that familial emotional climate, emotion regulation difficulties, and distress tolerance significantly predict addiction propensity in university students. These findings emphasize the necessity of incorporating family dynamics and emotional processing into targeted prevention and intervention strategies</span></span></span></span></div> Addiction, Distress tolerance, Emotions, Family, Students 53 58 http://ajnpp.umsha.ac.ir/browse.php?a_code=A-10-598-2&slc_lang=en&sid=1 Khadijeh Dashtbozorg dashtbozorgkdj@gmail.com 10031947532846008519 0009-0002-0792-6026 No Department of Psychology, Ahv.C., Islamic Azad University, Ahvaz, Iran.
