CAMPO-ARIAS, ADALBERTO et al. CONSISTENCIA INTERNA Y ANÁLISIS FACTORIAL DEL CUESTIONARIO SCOFF PARA TAMIZAJE DE TRASTORNO DE CONDUCTA ALIMENTARIA EN ADOLESCENTES ESTUDIANTES: UNA COMPARACIÓN POR GÉNERO. Univ. Psychol. [online]. 2006, vol.5, n.2, pp.295-304. ISSN 1657-9267.

Symptoms of eating disorders (ED) have increased among males recently. The SCOFF questionnaire for screening ED counts on a formal validation in Colombian only on girl students. However, psychometric properties of this questionnaire in males are unknown. The purpose of this study was to determine the internal consistency and factors of the SCOFF questionnaire and make a gender comparison among adolescent students from Bucaramanga, Colombia. A probabilistic sample of 2496 male and 2375 female, aged 10-19 year-old, completed the SCOFF questionnaire and the CAGE questionnaire that identifies abusive alcohol consumption (divergent validation). The internal consistency of the SCOFF was established with the Kuder-Richardson’s formula 20, and the divergence with the CAGE questionnaire with the Pearson’s correlation. Results showed among male an internal consistency 0.521, and among female a consistency of 0.584. One factor explained 34.7% of the variance in males, and one especifactor was responsible of 37.5% of variance in females. Finally, SCOFF scores and CAGE scores presented a poor correlation both males and females. In conclusion the SCOFF questionnaire presents an acceptable internal consistency, and a high divergence with the CAGE questionnaire among male and female adolescents. Further, the criterion validation of SCOFF questionnaire is needed for males.
