Social desirability and eating disorders. A community study of an Italian school‐aged sample

OBJECTIVE: To explore the links between social desirability and eating disorders in a sample of adolescents in a north-east area of Italy. METHOD: A mixed male-female sample of 1000 school-aged adolescents, corresponding to 10% of the young population aged 15-19 years living in the district, were investigated with self-reported questionnaires, including the Eating Attitudes Test (EAT), the Bulimic Investigatory Test of Edinburgh (BITE), the Body Attitudes Questionnaire (BAT), and an Italian version of the Marlowe-Crowne Social Desirability Scale (MC-SDS). RESULTS: Females scored higher than males at all eating disorder inventories. In both genders there was a negative relationship (in all cases P < 0.01) between scores at the eating disorder inventories and those at the MC-SDS. When analysing eating disorder "caseness", as measured by cut-off, "cases" reported significantly lower scores than "non-cases" at the MC-SDS in both genders. CONCLUSION: Personality traits measured by the MC-SDS, such as defensiveness, self-esteem, and dependence from approval, might contribute to the development of abnormal eating patterns at risk of eating disorders.
