Adolescent females under Child Protective Services care in Quebec, Canada (n = 328) completed a questionnaire designed to explore associations between prior victimization (childhood sexual abuse and four forms of dating violence) and four dimensions of sexual and contraceptive self-efficacy. Five MANCOVAs were performed. In each model, a victimization index served as the independent variable, four Contraceptive Self-Efficacy subscales as dependant variables, and age, age at first sexual intercourse, and lifetime number of sexual partners as covariates. Childhood sexual abuse was negatively associated with adolescent's perceived ability to communicate about her sexuality and contraceptive practices. Sexual coercion in dating relationships was negatively associated with the adolescent's perceived ability to communicate about her sexuality and contraception, her perceived control over her sexual activity, and her perceived control over her use of contraceptives in passionate situations. Sexual victimization was found to impair important aspects of adolescent females' sexual and contraceptive self-efficacy. (Contains 5 notes and 3 tables.)
