Network Analysis of Bulimia and Eating Behavior Regulation in Subclinical Population

Abstract

This study explores the complex relationships between various dimensions of eating behavior regulation and their impact on bulimia and food preoccupation using network analysis. The objective was to identify key regulatory mechanisms that influence bulimic behaviors and food-related obsessions. The study analyzed data from 659 participants, recruited via convenience sampling, using scales that measured intrinsic motivation, integrated regulation, identified regulation, introjected regulation, external regulation, amotivation, and bulimia and food preoccupation. Pearson’s correlation analysis revealed significant negative relationships between bulimia and both introjected regulation (r = −0.345, p < 0.001) and external regulation (r = −0.298, p < 0.001). Network analysis highlighted identified regulation and introjected regulation as central nodes with substantial influence over bulimia and food preoccupation, while integrated regulation demonstrated a significant indirect impact. The perception that food is necessary for life and energy, as well as for nourishment, enjoyment, social and cultural relationships, and emotional comfort, was further demonstrated using qualitative thematic analysis. The aforementioned results emphasize the pivotal functions of identified and introjected regulatory mechanisms in shaping conduct associated with food preoccupation and bulimia. According to the study, specific therapies that target these mechanisms may be essential for lowering bulimic symptoms and encouraging better eating practices.
