This study aimed to predict bulimia nervosa in adolescent girls based on emotion regulation and dispositional mindfulness. The present research employed a descriptive-correlational design. The statistical population consisted of female students aged 15–17 in Hashtroud County during the 2022–2023 academic year. Using a multi-stage cluster sampling method, a sample of 220 participants was selected, and completed the questionnaires. The research instruments included the Child and Adolescent Mindfulness Measure (CAMM; Greco et al., 2011), the Binge Eating Scale (BES; Gormally et al., 1982), and the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003). Data were analyzed using Pearson’s correlation test and multiple regression analysis. The findings showed that there is a significant negative relationship between reappraisal and trait mindfulness, and a significant positive relationship between suppression and bulimia nervosa in female students (p<0.01). Furthermore, emotion regulation and dispositional mindfulness collectively predicted the criterion variable, accounting for 23% of the variance in bulimia nervosa among female students (p<0.001). These results indicate that emotion regulation ability and the level of dispositional mindfulness play a determining role in the manifestation of bulimia nervosa in female students. Additionally, the findings underscore the importance of considering psychosocial variables to enhance mental health in this age group and highlight the necessity of incorporating strategies to strengthen these factors into care and support programs.
