This study examined the prediction of addiction tendency based on differentiation of self, self-construal, and coping styles. The primary aim was to identify the psychological factors significantly predicting addiction tendency and to analyze the relationships among these variables. The statistical population included all undergraduate students at Payame Noor University of Qom in 2021. Using simple random sampling, 285 students from various faculties were selected as the sample. Data were collected using standardized questionnaires, including the Addiction Tendency Scale, Differentiation of Self Inventory, Self-Construal Scale, and Coping Styles Inventory. Pearson correlation and multiple regression analysis were applied to analyze the data.The results indicated that differentiation of self, self-construal, and coping styles significantly predicted addiction tendency. Among these variables, coping styles had the highest predictive coefficient (β = 0.50), followed by differentiation of self (β = 0.45) and self-construal (β = 0.32). The findings revealed that individuals with lower differentiation of self and less effective coping styles are more likely to exhibit addiction tendencies.This study highlights the crucial role of psychological factors in understanding addiction tendencies and has significant implications for designing preventive and therapeutic interventions. The findings can serve as a scientific basis for promoting mental health and reducing high-risk behaviors, including addiction.
