The present study aimed to investigate the role of emotion regulation difficulties, forecasting, and personal values in predicting the fear of loneliness among university students with dependent personality disorder traits. A sample of 135 students from Islamic Azad University, Urmia Branch, who were identified as having dependent personality disorder traits based on the Dependent Personality Inventory-Revised (DPI-R), was selected via convenience sampling. Data were collected using the Student Loneliness Feeling Scale (SLFS), the Schwartz Value Survey (SVS), the Future-Orientation Questionnaire (FOQ), and the Difficulties in Emotion Regulation Scale (DERS). The results indicated a significant positive correlation between fear of loneliness and emotion regulation difficulties (p < .05), and significant negative correlations between fear of loneliness and both forecasting and personal values (p < .05). Regression analysis further revealed that emotion regulation difficulties, forecasting, and personal values collectively accounted for 68% of the variance in predicting fear of loneliness. Forecasting was found to have a greater share in predicting the criterion variable. The findings of this study suggest that forecasting, personal values, and emotion regulation difficulties have a significant impact on the fear of loneliness in students with dependent personality disorder traits.
