The relationship between body image dissatisfaction and the desire to be slim with a tendency for eating disorders was investigated. Female college students participated in a survey (N=237). Results of path analysis indicated that “dissatisfaction with other people's opinion of one's body” influenced “dissatisfaction with plumpness and the desire to be slim.” Also, “dissatisfaction with plumpness and the desire to be slim” caused “inappropriate dieting behaviors,” “apprehension concerning food intake,” and “binge eating.” Therefore, it is possible that sensitivity to other people's evaluations in interpersonal relationships originates from the tendency for eating disorders. These findings indicate that in the prevention and treatment of eating disorders, cognitive behavioral therapy is appropriate for addressing body image problems and problematic eating behaviors, including inappropriate dieting behaviors, whereas self-psychology and interpersonal therapy might be effective for problems related to the self, including values and roles. It is suggested that appropriate selection and integration of these psychotherapies could result in more favorable therapeutic outcomes.
