Peer influence on bulimic symptoms in college students.
This longitudinal study examined the influence of peer selection and socialization on bulimic symptoms in college students. Ninety-eight participants completed measures of bulimic symptoms, self-esteem, perfectionism, and impulsivity in the spring and fall of 2003. Peer influence was assessed by examining similarity among selected peers, unselected peers, and nonpeers over time. Among selected peers, bulimic symptoms demonstrated patterns of socialization, self-esteem and perfectionism demonstrated patterns of selection, and these personality traits longitudinally predicted changes in bulimic symptoms. Unselected peers demonstrated no similarity for bulimia, self-esteem, or perfectionism, but they did evidence socialization for impulsivity. The findings support an etiological model that integrates social and individual risk factors in creating environments that influence disordered eating among college students.
