Sexual Assertiveness Scale (SAS) for women: development and validation.

Four studies were conducted to develop and validate the Sexual Assertiveness Scale (SAS), a measure of sexual assertiveness in women that consists of factors measuring initiation, refusal, and pregnancy-sexually transmitted disease prevention assertiveness. A total of 1,613 women from both university and community populations were studied. Confirmatory factor analyses demonstrated that the 3 factors remained stable across samples of university and community women. A structural model was tested in 2 samples, indicating that sexual experience, anticipated negative partner response, and self-efficacy are consistent predictors of sexual assertiveness. Sexual assertiveness was found to be somewhat related to relationship satisfaction, power, and length. The community sample was retested after 6 months and 1 year to establish test-retest reliability. The SAS provides a reliable instrument for assessing and understanding women's sexual assertiveness.
