CONTEXT: Little research has explored how teenagers think about abstinence and how it functions in their lives. These questions are particularly salient in light of widespread funding of abstinence-only programs in the United States. METHODS: Data on attitudes and intentions related to abstinence and sex were collected from 365 adolescents aged 12–15 who participated in an HIV risk reduction program in Seattle in 2001–2003. Logistic regression analyses assessed associations between these cognitions, as measured six months after the program, and teenagers’ likelihood of having vaginal or anal sex in the subsequent six months. RESULTS: Adolescents who had positive attitudes and intentions about abstinence had a reduced likelihood of subsequently engaging in sex (odds ratio, 0.6 for each), whereas those with positive attitudes and intentions about having sex had an elevated likelihood of engaging in sex (2.2 and 3.5, respectively). A regression model including only sex cognitions accounted for substantially more variation in sexual activity than did one including only abstinence cognitions (15–26% vs. 6–8%). Significant interaction effects were also seen: Among teenagers with low levels of sex intention, greater abstinence intention had little relationship to the predicted probability of having sex, but among teenagers with high levels of sex intention, greater abstinence intention was associated with increases in the predicted probability of having sex. CONCLUSIONS: Youth do not consider abstinence and sexual activity opposing constructs, and solely instilling positive abstinence attitudes and intentions in youth may not have robust effects in preventing sexual activity.

Presents a study which investigated the relationship between adolescent drinking and risky sexual behaviors. Overview of the study population; Methodology; Findings.

We examined the utility of the theory of reasoned action for predicting sexual intercourse among teenagers and determined whether it holds for both genders and for those with and without prior sexual experience. The data include 749 students who were in 9th-llth grades when the predictors were measured and in 10th-12th grades when sexual intercourse was assessed. About half (53%) were girls, about half (48%) were non-Hispanic European Americans. Results showed that prior sexual experience was related to a higher rate of sexual intercourse, but boys and girls did not differ. Tests of the causal model for subgroups (boy and girl virgins, boy and girl nonvirgins) yielded similar results. As predicted, paths from intentions to behavior and from norms and attitudes to intentions were significant, as were paths from outcome and normative beliefs to attitude and norm, respectively.

This research examined the applicability of the theory of reasoned action to school-age children. Using structural equation modeling, we longitudinally modeled children's attitudes, norms, intentions, and behavior with regard to drinking alcohol. Respondents were 1,061 children attending public schools in the northwestern United States. Attitude, norms, and intentions (measured when the children were in 6th, 7th, 8th, and 9th grades) were used to predict alcohol use 1 year later. Two modifications of the model improved the overall fit at each grade level: separating attitude into 2 dimensions (positive and negative), and adding a path from social norm to behavior. The theoretical and practical implications of these results are discussed. [ABSTRACT FROM AUTHOR]

This research examines the applicability of Fishbein and Ajzen's (1975) theory of reasoned action (TRA) to intentions to use cigarettes and alcohol among 5th- and 6th-grade students. It also addresses the question of unidimensionality of outcome beliefs and referent norms. Results suggest that the TRA model describes children's decision making well, although the ability of income and race to add to prediction, net of the effects of attitude and perceived norm, are contrary to the theory's prediction. In addition, we find support for multidimensional components of both altitude and norm for both behaviors. [ABSTRACT FROM AUTHOR]
