Self-efficacy in the use of condoms is related to health, especially in the prevention of sexually transmitted infections. This research sought to adapt the Condom Use Self-Efficacy Scale for the Brazil. For this, two studies were conducted through an online questionnaire. Study 1 had 332 participants from the general population; the majority of women (63.6%), with a mean age of 25.2 years (SD = 7.4). The exploratory factor analysis identified four factors: Ability, Assertiveness, Pleasure and Drugs and Sexually Transmitted Diseases, explaining 66.8% of the variance. Study 2 had 907 participants, with a mean age of 23.6 years (SD = 6.1). Confirmatory factor analysis corroborated the structure found: GFI = 0.93; CFI = 0.91; RMSEA = 0.08 (IC 90% = 0.07-0.09). The results proved the adequacy of the measure, gathering evidence of validity. The importance of this measure in health research is discussed. [ABSTRACT FROM AUTHOR]
