Contraceptive and sexual behavior of black female adolescents. A test of a social-psychological theoretical model.

To test a previous theoretical model, we studied the relationships between social, attitude, and psychological factors and adolescent contraceptive behavior over a 6-month period. A pretested questionnaire was administered to a random sample of 115 black females aged 12 to 18 years from a low socioeconomic population. Six months after the initial interview 113 of the subjects were administered a second questionnaire assessing their sexual and contraceptive behavior. Based on regression analysis, previous pregnancy and coital frequency explained 12.7% (p less than or equal to 0.0001) of the variation in engaging in unprotected coitus. When controlling for sexual activity, birth control knowledge and previous broken appointments explained an additional 5.5% of variation in the regression model (total R2 = 0.185). Coital frequency of the subjects was positively associated with Tanner stage, length of the relationship, effectiveness of previous contraceptive method(s), and degree of birth control knowledge. Coital frequency was inversely associated with a negative attitude toward pregnancy and negative parental attitudes toward adolescent pregnancy. The perceived risk of pregnancy was positively correlated with coital frequency and previous pregnancy. These findings support our model, but suggest that among low socioeconomic black female adolescents the interpretation of several model components depends on the subjects' attitude toward pregnancy and her perception of her parent's attitude toward adolescent pregnancy.
