Abstract
Background and Aim:Anorexia nervosa (AN) is a critical psychological disorder characterized by life-threatening distress, significant weight loss, and distorted body image. This study aimed to explore the mediating role of rumination in the relationship between behavioral inhibition/approach systems (BIS/BAS), metacognitive beliefs (MCB), attachment styles (AS), and AN.Materials and Methods:Conducted as modeling research, this study focused on Tehran's student population, employing a multi-stage cluster sampling method. The research involved 215 girl students who completed assessments included the Eating Disorder Diagnostic Scale, Ruminative Responses Scale, sensitivity to reinforcement scale, metacognitive beliefs-30, and attachment styles. Data analysis employed the partial least squares method in SPSS and Smart-PLS software.Results:The results indicate that the revised model of the structural relationship among sensitivity to reinforcement, metacognitive beliefs, attachment styles, and AN, with the mediation of rumination, exhibits appropriate fitness characteristics.Conclusion:The confirmed mediation of rumination in the complex interplay of BIS/BAS, MCB, AS, and AN reveal a crucial cognitive pathway, deepening our understanding of the disorder's etiology. This underscores the potential efficacy of interventions targeting rumination, prompting a paradigm shift in therapeutic strategies. Recognizing rumination as a central mediator allows for a focused approach, addressing the multifaceted aspects of AN and opening avenues for more effective interventions to support individuals grappling with the disorder.
