Validez y confiabilidad del Eating Attitudes Test en Costa Rica

Abstract

Se exponen evidencias de validez y confiabilidad del Eating Attitudes Test (EAT-40) en Costa Rica. En el Estudio 1 se adaptó el EAT-40 al léxico costarricense y se aplicó a 594 adolescentes. Se obtuvo un alfa de Cronbach de .87. El riesgo de desarrollar trastornos de la conducta alimentaria (TCA) fue mayor en mujeres (18.6%) que en hombres (7.4%) y correlacionó con la identificación con modelos televisivos (r = .725) y con la insatisfacción con el aspecto físico (r = .562). En el Estudio 2 se compararon las puntuaciones de mujeres con TCA (n = 19) y sin él (n = 533). Se obtuvieron buenas propiedades de discriminación a partir de los puntajes de corte de 30 (sensibilidad 63.2%, especificidad 85.8%) y de 20 (sensibilidad 73.7%, especificidad 71.8%). En el Estudio 3 se aplicó el EAT-40 a una muestra nacional de adolescentes de ambos sexos (n = 4,285). La prevalencia del riesgo fue de 6.2%, siendo mayor en mujeres (9.4%) que en hombres (2.3%) y los mejores predictores del riesgo en mujeres fueron los malestares psicosomáticos (β = .275) y el nivel de satisfacción con la imagen corporal (β = -.159).

The paper reports evidence of validity and reliability of the Eating Attitudes Test (EAT-40) in Costa Rica. In Study 1, the EAT-40 was adapted to Costa Rican lexicon and applied to 594 adolescent. A Cronbach´s alpha of .87 was obtained, the risk of developing eating disorders (ED) was higher in women (18.6%) than men (7.4%), and this risk correlated with the identification with television models (r = .725) and with the dissatisfaction with physical appearance (r = .562). In Study 2, scores of women with ED (n = 19) and without it (n = 533) were compared. Good discrimination properties were obtained from the cut points of 30 (sensitivity 63.2%, specificity 85.8%) and 20 (sensitivity 73.7%, specificity 71.8%). In Study 3 the EAT-40 was applied to a national sample of adolescents of both sexes (n = 4285). The prevalence of risk was 6.2%, being higher in women (9.4%) than in men (2.3%) and the best predictors of risk in women were psychosomatic symptoms (β = .275) and the level of satisfaction with the body image (β = -.159).
