The purpose of this research was to examine and extend portions of the sociocultural model of bulimia nervosa (Stice, E. (1994). Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action. "Clinical Psychology Review," 14, 633-661; Stice, E., & Agras, W. S. (1998). Predicting onset and cessation of bulimic behaviors during adolescence: A longitudinal grouping analysis. "Behavior Therapy," 29, 257-276). Participants were women who reported engaging in binge eating at baseline and the 1-year follow-up (n = 26), women who began binge eating between these 2 points (n = 25), and women who did not report binge eating during the course of the study (n = 199). Results of the first discriminant function analysis provided support for the sociocultural model. However, the results of subsequent analyses suggest that additional variables, including stress, escape-avoidance coping, and interoceptive awareness, emerged as important. Implications of these findings for our understanding of the development and maintenance of binge eating are discussed. (Contains 2 tables.)
