Understanding eating disorder symptoms in adolescents: testing a cognitive-behavioural model of eating disorders in a community sample.

Clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties are associated with eating disorder symptoms in clinical samples. The aim of the current study was to test a model including clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties to understand eating disorder symptoms in an adolescent community sample. Adolescents ( N  = 446, M age = 16.25 years, SD  = 1.64; 74.2% female) completed measures of clinical perfectionism, self-esteem, mood intolerance, interpersonal difficulties, and eating disorder symptoms. Path analysis indicated clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties were all directly associated with symptoms of eating disorders, and that clinical perfectionism was indirectly associated with eating disorders through self-esteem, mood intolerance, and interpersonal difficulties. The results indicate the cognitive-behavioural model of eating disorders can be applied to adolescents in the community with symptoms of eating disorders. Directional causality between constructs should be established to understand whether increased clinical perfectionism, and reduced self-esteem, mood intolerance, and interpersonal difficulties are vulnerabilities to the development and maintenance of eating disorders.
