RESUMEN

Objetivo. Examinar el desempeño psicométrico del SCOFF, un instrumento de tamizaje para trastornos de conducta alimentaria (TCA). Material y métodos. Aspirantes mexicanos a una universidad (n = 3594, 55.7% mujeres, edad M = 18.1 años) completaron cuestionarios y una revisión médica. Resultados. Análisis factoriales confirmatorios revelaron un factor para mujeres, aunque un modelo bifactorial funcionó mejor para hombres y mujeres. La fiabilidad fue menor en mujeres (KR20= .49) que en hombres (KR20= .59). Las mujeres (24.2%) presentaron mayor riesgo de TCA (SCOFF › 2) que hombres (11.2%). Validez nomológica indicó que el riesgo de TCA en mujeres jóvenes estuvo asociado con indicadores demográficos (e.g., educación paterna), psicológicos (e.g., depresión, control eficaz de peso), físicos (e.g., IMC), y sociales (e.g., conflicto familiar) de forma conceptualmente coherente. Un subconjunto de estas variables fueron significativas para los hombres. Conclusión. El SCOFF podría ser un tamizaje de TCA útil en México. Sin embargo, se requiere más investigación sobre su validez de criterio, sensibilidad y especificidad.
