Validity of Body Shape Questionnaire (BSQ) In Mexican Women

espanolEl objetivo de la presente investigacion fue validar el instrumento en poblacion mexicana femenina Body Shape Questionnaire (BSQ), creado con la finalidad de evaluar la insatisfaccion corporal. Participaron 472 mujeres, 256 eran estudiantes (x. = 15.9, DE = 3.2) y conformaron el grupo control y 216 pacientes con Trastorno del Comportamiento Alimentario (TCA) (x. = 20.5, DE = 3.9) con un rango de edad de 13 a 30 anos. Los resultados mostraron una excelente consistencia interna (�? = .98), asi como una estructura de 2 factores que explicaron el 63.8% de la varianza total. Estos fueron: 1) Malestar corporal normativo (�?=.95) y 2) Malestar corporal patologico (�?=.94). Respecto a la validez discriminante y predictiva, el BSQ mostro una buena capacidad de clasificar a individuos con TCA, en funcion de la insatisfaccion corporal, y se observo que dicha capacidad es mayor cuando discrimina entre Anorexia, Bulimia y control (�E de Wilks = .485, �O2(gl=1)= 278.830, p. .001). Finalmente se exploraron 6 diferentes puntos de corte, de los cuales 110 fue el que demostro ser el mas apropiado, de acuerdo a sus valores de sensibilidad (84.3%) y especificidad (84.4%). En conclusion el BSQ es un cuestionario de gran utilidad para detectar la insatisfaccion corporal en mujeres mexicanas. EnglishThe aim of this study was to validate the instrument Body Shape Questionnaire (BSQ) in female Mexican population, created to assess body dissatisfaction. 472 women participated, 256 were students and formed the control group (x. = 15.9, DE = 3.2) and 216 patients with Eating Disorders (ED) (x. = 20.5, DE = 3.9) with an age range of 13 to 30 years. The results showed excellent internal consistency (�? = .98) and a 2-factor structure that explained 63.8% of the total variance. These were: 1) normative body uncomfort (�?=.95), and 2) pathological body uncomfort (�?=.94). Regarding the discriminant and predictive validity, the BSQ showed good ability to classify individuals with eating disorders, depending on body dissatisfaction, noting that such capacity is greater when discriminating between Anorexia, Bulimia and control (�E de Wilks = .485, �O2(gl=1)= 278.830, p. .001). Finally we explored 6 different cut off points, of which the 110-was proved to be the most appropriate according to their values of sensitivity (84.3%) and specificity (84.4%). In conclusion, the BSQ is a useful questionnaire to detect body dissatisfaction in Mexican women.
