Structural Equation Modeling Test of an Integrated Model of Spanish Youth's Condom Use.

Heterosexual transmission represents 26 % of newly diagnosed infection in Spanish youth. Behavioral change models have emphasized the influence of multiple variables to predict condom use behavior. The aim of this study is to examine how those variables are organized and which theory explains the condom use behavior better. A sample of 424 young heterosexuals (M _age  = 20.62; SD = 2.16) filled out a battery of self-report questionnaires for assessing AIDS-related variables, personality traits and clinical variables (general, sexuality-related and health-related). A structural model was specified that included perceived pleasure and condom use self-efficacy as predictive variables. Depression and sexual compulsivity indirectly influence behavior. The final model accounted for 65.9 % of the variance in behavior. These results highlight the importance of cognitive and emotional variables as predictors of behavior (ex. expectations of pleasure and self-efficacy beliefs). This is important information for designing effective psychological interventions.
