HIV and STI Prevention Among Spanish Women Who have Sex with Women: Factors Associated with Dental Dam and Condom Use.

The scientific community has systematically ignored the needs of women who have sex with women (WSW). The invisibilization of romantic and sexual relationships between women has caused a profound lack of knowledge about the impact of HIV and other STIs on this population subgroup. This study aims to analyze the frequency of dental dam and condom use in WSW and identify the variables that explain the use of these two preventive methods. The sample is composed of 327 women aged between 18 and 60 years (M = 27.82; SD = 8.10). The results indicate that only 4.7% of those who practice cunnilingus and 5.2% of those who practice anilingus report "always" using dental dam (systematic use). Condoms are used systematically by 37.1% of those who practice vaginal penetration and 37.8% of those who practice anal penetration. Age, high perceived self-efficacy, and adequate assertive communication skills are variables significantly related to preventive behavior. The severity attributed to HIV and the perceived risk of infection are protective factors regarding dental dam use. For condom use, high levels of internalized homophobia and drug use are risk factors. Future preventive strategies should provide information on preventive strategies to WSW who, for different reasons, are not involved in LGBT contexts or associations and, therefore, do not have access to training activities and mistakenly believe that they are invulnerable as they do not have sexual relations with men.

Construction and Validation of a Self-Efficacy Scale for Latex Barrier Use.

Some studies have concluded there is a relationship between perceived self-efficacy and behaviors that prevent HIV transmission. This paper presents the construction and validation of the latex barrier use self-efficacy scale (LBSS), which 480 participants filled out. Exploratory factor analysis yielded two components: positive expectations of self-efficacy (ES-POS) and negative expectations of self-efficacy (ES-NEG), which together accounted for 65.59% of total variance. That structure was later verified through confirmatory factor analysis. Internal consistency was .80 for the total scale, and .78 for each of the two factors. Moreover, the instrument had adequate convergent validity and was positively related with condom use self-efficacy, attitudes toward condom and latex barrier use, and ability to refuse sex if the partner refuses to use preventive methods. In conclusion, this instrument is a useful measure of self-efficacy in latex barrier use.
