Publisher: | Consorcio de Universidades Mexicanas A.C. | Description: | The aims of this paper were to compare the 3-factor model proposed by Moral and Valle (2011), for the ATLG scale, and provide validity evidences for it. The ATLG scale (Herek, 1984), the internalized homonegativity scale (HNI-16; Moral & Valle, 2013) and the homophobia scale (HFK- 10; Klamen, Grossman, & Kopacz, 1999) were applied to a non-probabilistic sample of 231 Mexican students of health sciences (121 women and 103 men). Three structural models were contrasted by Generalized Least Squares (GLS): one general factor, two correlated factors and three factors hierarchized to a general factor. The models of two correlated factors and three hierarchized factors had an equivalent goodness of fit and were significantly higher than the one-factor model. However, the data showed unidimensionality based on three arguments: 1) the values of correlations and regression coefficients of first-order factors were very high, 2) Horn’s parallel analysis indicated that the number of factors is one, and thus the variance explained by a second or third factor could be due to random, and 3) the goodness of fit of the unidimensional model was acceptable and very similar to that of the other two models. The correlations of the ATLG total score with the total scores of HNI-16 and HFK-10 were high. The self-defined sexual orientation and having gay friends had a medium size effect on the ATLG total score. It is concluded that the ATLG scale is unidimensional, and shows validity evidences. A simplified form of 5 items is suggested. Este artículo tiene como objetivos contrastar el modelo tridimensional de Moral y Valle (2011), para la escala ATLG y aportar pruebas de su validez. Se aplicaron las escalas ATLG (Herek, 1984), de homonegatividad internalizada (HNI-16; Moral & Valle, 2013) y homofobia (HFK-10; Klamen, Grossman, & Kopacz, 1999) a una muestra no probabilística de 231 estudiantes mexicanos de Ciencias de la Salud (121 mujeres y 103 hombres). Se contrastaron tres modelos por Mínimos Cuadrados Generalizados (GLS): de un factor, dos factores correlacionados y tres factores jerarquizados a uno general. Los modelos de dos factores correlacionados y de tres factores jerarquizados tuvieron una bondad de ajuste equivalente y significativamente mayor que la del modelo unidimensional. No obstante, los datos reflejaron unidimensionalidad con base en tres argumentos: 1) los valores de correlación y coeficientes de regresión de los factores de primer orden fueron muy altos; 2) el análisis paralelo de Horn indicó que el número de factores es uno, por lo que la varianza explicada por un segundo o tercer factor se debería al azar; y 3) la bondad de ajuste del modelo unidimensional fue aceptable y muy semejante a la de los otros dos modelos. Las correlaciones de la puntuación total de la ATLG con las de HNI-16 y HFK-10 fueron altas y significativas. La orientación sexual autodefinida y tener amigos homosexuales tuvieron un efecto mediano sobre la ATLG. Se concluye que la ATLG es unidimensional y posee evidencias de validez. Se sugiere una forma simplificada de 5 ítems. |
