Este estudio tiene como objetivos: contrastar los modelos de uno y tres factores propuestos para el Índice de Satisfacción Sexual (ISS), y estimar la consistencia interna y validez convergente y discriminante de sus factores. Se administró el ISS a 807 personas casadas o en unión libre de Monterrey, México, usando un muestreo de rutas aleatorias. El modelo trifactorial no se validó. Una vez eliminados los ítems 5, 11, 13 y 15 con problemas de consistencia interna, el factor único mostró validez convergente y consistencia interna, y el ajuste del modelo de un factor mejoró. Su ajuste fue perfecto cuando se redujo a 10 indicadores. Se sugiere redefinir el ISS como una escala unidimensional con 10 ítems que evalúa satisfacción sexual.
The objectives of this study were to contrast the models of one and three factors proposed for the Hudson’s Index of Sexual Satisfaction (ISS), and estimate the internal consistency, convergent and discriminant validity of its factors. The ISS was administered to 807 married or unmarried individuals from Monterrey, Mexico, using a random route sampling. The three-factor model was not validated. Once items 5, 11, 13 and 15 with problems of internal consistency were deleted, the single factor showed convergent validity and internal consistency, and the fit of the onefactor model improved. Its fit was perfect when it was reduced to 10 indicators. It is suggested to redefine the ISS as a 10-item one-dimensional scale assessing sexual satisfaction.
