    El modelo de Información-Motivación-Destrezas (IMB) evalúa factores que facilitan la promoción de practicas sexuales de menor riesgo. El presente estudio examinó la aplicación de este modelo en una muestra puertorriqueña utilizando la modelación de ecuaciones estructurales con adultos heterosexuales con al menos una pareja estable. A la vez, evaluamos si el modelo podía ser aplicado a más de una muestra. La primera muestra (N= 291) completó la versión en papel y lápiz de el instrumento, mientras la segunda muestra (N= 756) completó la versión electrónica del mismo. Los resultados reflejan que existe una asociación de predicción entre los componentes del modelo IMB, donde el tener información sobre el VIH/SIDA predijo el nivel de motivación para tener sexo más seguro, y este factor a la vez predijo el nivel de autoeficacia para la negociación sexual (destrezas). Estos resultados apuntan la necesidad de identificar múltiples factores que facilitan las prácticas sexuales de menor riesgo.

    The Information-Motivation-Behavioral Skills model examines factors that are used to initiate and maintain sexual and reproductive health promotion behaviors. The present study evaluated the association among these constructs as it is applied to sexually active heterosexual adults with steady partners, using a Structural Equation Modeling approach. At the same time, it was analyzed if the same model structure could be generalized to two samples of participants that produced the results following two different formats for data collection. Two-hundred ninety one participants completed the Information-Motivation- Behavioral Skills Questionnaire (Spanish version), and 756 participants completed an Internet version on the instrument. The proposed model fits the data for both groups, supporting a predictive and positive relationship among all of the latent variables, with Information predicting Motivation, and Motivation therefore predicting Behavioral Skills. The findings support the notion that there are important issues that need to be addressed when promoting HIV prevention.
