Construction and validation of the self-efficacy scale to the use of condom in mexican adolescents

Abstract

Introduction: Among adolescents sexual transmitted infections and pregnancies can be combated through the use of condoms. It is important not just educate, but determine the skills for the use of condom. Here is where self-efficacy grows in importance, since it’s a cognitive element to determine the confidence the adolescent has to use the condom correctly. In Mexico and Latin-America there is no evidence on the construction and validation of an instrument exclusively on the use of condoms in adolescents in Spanish and culturally feasible.

Objective: Construct and validate an instrument to evaluate the adolescents’ self-efficacy in the use of condom.

Method: Design in process to transversal scope. One hundred thirty adolescents were included in the sample.

Results: The statistical analysis included the judges’ technique with a content validity index of 8.64. Cronbach Alpha .86, KMO=.795, Bartlett Sphericity p<.05. The factor analysis was exploratory, and the first 5 items explained more than 70% of variance and when factors rotate 4 groups were evident. The instrument final version consists of 17 items with a Likert-type response format represented by small faces and corresponding to 1=never, to 5=always.

Conclusion: An instrument created within the Mexican territory cultural context was obtained. It measures the adolescents’ self-efficacy to the use of condom; however, it is necessary to test the instrument in other cultural context different from the Mexican context to prove its external validity.
