Abstract
Self-efficacy seems to be one of the most important resources for the different stages underlying condom use and STI prevention. For this reason, this study evaluates trends in self-efficacy by gender, from 2004 to 2008, 2013 and 2020 in Spain. Throughout these years, 6,698 people ranging from 17 to 40 years old, participated filling the Brief scale of condom use self-efficacy. According to our findings, despite the slight improvement in the recent years, self-efficacy still maintains a risky profile for safe sex, especially among the youngest people. Moreover, most of the traditional gender differences continue over the years with women reporting lower scores for condom purchase and men for putting them. However, these differences are not relevant in other dimensions such as using condoms despite drug consumption where women reveal worse results over the years. Therefore, our findings reaffirm the need of intensifying gendered preventive efforts aimed at Spanish people and, particularly, among the youngest.
