Adaptação portuguesa e validação da versão reduzida da Condom Use Self‐efficacy Scale

Abstract

IntroductionCondoms are the most effective method to prevent sexually transmitted infections. The role of self‐efficacy in predicting health behaviors and self‐efficacy to use condoms has been shown to be a key related construct to the effective use of condoms. ObjectivesAdaptation and validation of the reduced version of Condom Use Self‐efficacy Scale (CUSES) for Portuguese college students. Material and methodsWe conducted a quantitative, descriptive and correlational in a convenience sample of 1946 university students study, 64% girls and 36% boys, mean age 21 years (20.74±2.32). ResultsThe analysis of the psychometric characteristics of the scale was carried using exploratory (EFA) and confirmatory factor analysis (EFC), held in 2 randomized subgroups of the original sample. The results of EFA revealed a structure with four factors, which explains 70.6% of variance and have a good values of internal consistency (α=0.86). The AFC revealed the need to adjust the model to the data, presenting acceptable levels of adjustment. The modified version had good reliability, factorial validity and concurrent and discriminant validity. ConclusionsThe psychometric properties assessed allow considering the use of this instrument in the development of sexual and reproductive health programs for students of Portuguese higher education as it allows determining the relevant fields of self‐efficacy perception to use condom.
