Validación de la Sexual Assertiveness Scale en mujeres mexicanas

Given its relationship to various indicators of sexual health, sexual assertiveness is a fundamental dimension of human sexuality. This is defined as the ability that people have to initiate sexual activity, refuse unwanted sexual activity, and use contraceptive methods, thereby developing healthy behaviours — which can be measured using the Sexual Assertiveness Scale (SAS). To date, the SAS has not been validated in the Mexican population, albeit it is considered important to examine the psychometric properties of the latter. Therefore, to the aim of this study was to validate the SAS in a sample of 202 Mexican women. Confirmatory factor analysis confirmed the three-factor structure of the SAS: initiation, rejection, and pregnancy-sexually transmitted diseases (CFI = .953; TLI = .927). Similarly, adequate reliability was obtained in the three subscales and overall (ω = .85). Their scores significantly correlated in the expected direction with sexual self-esteem and the trait depression. It is concluded that the SAS has psychometric properties which are acceptable in Mexican women.
