[Validation of the SCOFF questionnaire for screening the eating behaviour disorders of adolescents in school].
OBJECTIVE
To determine the internal consistency and criteria validity of the SCOFF questionnaire for screening adolescent eating behaviour disorders.


METHODS
Validation study with stochastic sampling.


METHODS
Three schools at Bucaramanga, Colombia.


METHODS
241 students selected at random from 1595 possible ones.
SCOFF questionnaire and semi-structured CIDI interview, administered independently.


METHODS
Social and personal details, Cronbach's alpha, sensitivity analysis, specificity, forecast values, Cohen mean kappa test, and ROC curve.


RESULTS
Sensitivity found was 81.9% (95% CI, 70.7-89.7) and specificity, 78.7% (95% CI, 71.7-84.6). The area under the ROC curve was 0.8596 (95% CI, 0.8108-0.9084); the Cronbach's alpha test, 0.436, and the Cohen mean kappa, 0.554 (95% CI, 0.425-0.683).


CONCLUSIONS
The SCOFF questionnaire is an acceptable alternative for screening groups of adolescents because of its simplicity and speed of administration.
