Research suggests that parents' expectations for their adolescents' college attainment contribute to their adolescents' expectations, and that adolescent girls' expectations to attend college play a role in preventing and postponing teenage pregnancy. Through structural equation modeling, the present investigation examined the influence of maternal educational expectations on their daughters' childbearing attitudes and whether it was mediated through communication about education and the daughters' educational expectations. One hundred and forty-six Latina adolescent girls and their mothers from low-income backgrounds completed measures tapping into their educational expectations as measured by their certainty regarding whether the girls could reach their educational goals, communication about education, the girls' desired childbearing ages and their attitudes toward teenage pregnancy. In addition to survey measures, educational communication was assessed by coding educational messages in videotaped mother-daughter conversations about dating and sexuality. Results indicated that mothers with higher educational expectations engaged in more communication with their daughters about the value of education, which in turn was associated with the daughters having more rejecting attitudes toward teenage pregnancy. Mothers' and daughters' expectations were positively associated, and daughters' high expectations was linked to desires to have a first child at older ages. Findings suggest that girls with high expectations expect childbearing to conflict with their chances of obtaining a college degree. The findings also highlight the need for mothers to communicate their expectations and values on education regularly to and include messages about the importance of education when talking to daughters about sexuality to prevent teenage pregnancy.
