Adolescents' Transition to First Intercourse, Religiosity, and Attitudes about Sex

Using two waves of the National Longitudinal Study of Adolescent Health, this study examines two sets of relationships between attitudes, religiosity, and first sex among adolescents. First, I estimate the effects of religiosity and attitudes about sex on the likelihood of engaging in first sex. Then, I estimate the effect of having sex on subsequent religiosity and attitudes. The findings are consistent with past research that finds attitudes are a significant predictor of sexual activity. The effect of religiosity on first sex is mediated by attitudes about sex. Regarding reciprocal effects, having sex for the first time has a significant effect on later attitudes, but not religiosity. This study highlights the importance of going beyond traditional, recursive models that consider only one side of a causal relationship.
