This study explored eating disorder risk factors and possible psychosocial predictors of this risk in overweight and obese treatment-seeking adolescents. Prior to commencing treatment 108 overweight and obese adolescents aged 11 to 17 years (
M =14.31, SD =1.57; 55% female) completed self-report measures of psychosocial factors. Females reported elevated levels of bulimic tendencies, body dissatisfaction, drive for thinness ( p≤.001) and males reported elevated body dissatisfaction ( p< .001). Age, sex and BMI-for-age z-score explained 15% ( p< .001) of the variance in eating disorder risk and psychosocial predictors an additional 25%. Sex did not have a moderating effect on these relationships ( p= .21). Among overweight and obese treatment-seeking adolescents, those experiencing lower self-esteem and elevated depression and anxiety symptomatology are at increased eating disorder risk. This highlights the need to consider psychosocial factors in preventing and treating overweight and obesity.
