Stole Lhiver,c.ip of iVrw YorkCommunication between mothers and adolescents about premarital sexual intercourse uas studied in the context of a model of maternal influence on the formation of adolescent beliefs about sexual behavior. Two different fnrms of maternal influence were explored: (a) direct communication. and (b) indirect transmission of maternal orientations. Respondents were 751 inner-city. African American adolescents (ages I4 to 17) and their mnthers. Results indicated that adolescent motivations were related to their sexual behavior, and that maternal beliefs about sex were predictive of those motivations. independent of reports of the amount of communication that had taken place. These data are consistent with a model that underscores multiple mechanisms by which parents influence adnlescent sexual behavior over and above direct communication.Despite recent efforts aimed at persuading adolescents to postpone sexual activity, a substantial number of teens are engaging in premarital sexual intercourse. Studies have shown that by 9th grade, approximately 37% of adolescents have had intercourse. This rate increases by about 10% a year, until by 12th grade, 66% have engaged in intercourse (Centers for Disease Control, 1996). Approximately 73% of adolescent males and 56% of adolescent females have had intercourse by age 18, compared with 35% of adolescent females and 55% of adolescent males in the early 1970s (Alan Guttmacher Institute, 1994). Accompanying this early onset of sexual activity is the risk of pregnancy and sexually transmitted diseases (STDs).It has been noted that many adolescents fail to use some form of pregnancy protection at first intercourse (Alan Guttmacher Institute, 1994; Centers for Disease Control, 1996). Consistent use of contraceptives seems to be at its lowest during the early stages of sexual activity, which results in a significant number of teenage pregnancies occurring within the first year of sexual initiation (Jaccard &
