This study presents a descriptive analysis of the content, frequency, and timing of couple communication regarding birth control among stable, sexually active adolescent couples, and the effect of communication on actual contraceptive practices. The sample consisted of 83 couples in which the female partner was 15-18 years old. All couples had been sexually active at least two months prior to the interview. The majority of couples had discussed birth control on at least one occasion, but discussions prior to first intercourse were atypical. Couples with good communication patterns were more likely to practice effective contraception. One-fourth of the respondents felt that contraception had not been adequately discussed, and these individuals were found to be most at risk to an unintended pregnancy.
