Аннотация
OBJECTIVE: This article describes the three-stage development of the SCOFF, a screening tool for eating disorders.
METHOD: Study 1 details questionnaire development and testing on cases and controls. Study 2 examines reliability of verbal versus written administration in a student population. Study 3 validates the test as a screening tool in primary care.
RESULTS: The SCOFF demonstrates good validity compared with DSM-IV diagnosis on clinical interview. In the primary care setting it had a sensitivity of 84.6% and a specificity of 89.6%, detecting all true cases of anorexia nervosa and bulimia nervosa and seven of nine cases of EDNOS. Reliability between written and verbal versions of the SCOFF was high, with a kappa statistic of 0.82.
DISCUSSION: The SCOFF, which has been adapted for use in diverse languages, appears highly effective as a screening instrument and has been widely adopted to raise the index of suspicion of an eating disorder.
