Examining the Effects of an Adolescent Pregnancy Prevention Program by Risk Profiles: A More Nuanced Approach to Program Evaluation

Who Benefits from School-Based Teen Pregnancy Prevention Programs? Examining Multidimensional Moderators of Program Effectiveness Across Four Studies

Recent research has suggested the importance of understanding for whom programs are most effective (Supplee et al., 2013) and that multidimensional profiles of risk and protective factors may moderate the effectiveness of programs (Lanza & Rhoades, 2012). For school-based prevention programs, moderators of program effectiveness may occur at both the individual and school levels. However, due to the relatively small number of schools in most individual trials, integrative data analysis across multiple studies may be necessary to fully understand the multidimensional individual and school factors that may influence program effectiveness. In this study, we applied multilevel latent class analysis to integrated data across four studies of a middle school pregnancy prevention program to examine moderators of program effectiveness on initiation of vaginal sex. Findings suggest that the program may be particularly effective for schools with USA-born students who speak another language at home. In addition, findings suggest potential positive outcomes of the program for individuals who are lower risk and engaging in normative dating or individuals with family risk. Findings suggest potential mechanisms by which teen pregnancy prevention programs may be effective.

More than the sum of their parts: A dyad-centered approach to understanding adolescent sexual behavior

BACKGROUND

Research has documented multiple levels of influences on adolescent sexual behavior, but has generally focused less on the relational nature of this behavior. Studies with dyadic data have provided important findings on relationship process, including the role of gender in different-sex dyads. However, both of these bodies of literature typically utilize a variable-centered approach, which examines average influences of particular variables on sexual behavior. This study expands upon this research by presenting a dyad-centered approach to adolescent sexual behavior that can identify types of couples based on patterns of multidimensional risk and protective factors.

METHODS

I demonstrate the dyad-centered approach using data from different-sex dyads in the National Longitudinal Study of Adolescent to Adult Health to uncover profiles marked by individual, parent, peer, and religion predictors for both male and female partners.

RESULTS

Analyses uncovered five classes of dyadic influences, four of which were marked by relative similarity between partners and one marked by lesser approval of sex for women compared to men. Dyads marked by both partners intending to have sex and being in a context that is more approving of sex were more likely to engage in sexual intercourse.

CONCLUSIONS

Findings demonstrate the heterogeneity of influences and intentions to have sex among adolescent couples, and identify profiles of dyads who are more likely to engage in sexual intercourse. This approach can explicate dyadic processes involved in sexual behavior and the types of couples that exist in a population, leading to more tailored and efficacious interventions.

Teen pregnancy in Chicago: Who is at risk?

BACKGROUND

Teenage pregnancy, with its associated health and social consequences for young people and society as a whole, is one of the nation's most important public health issues. The purpose of this study was to use Youth Risk Behavior Survey (YRBS) data describe self-reported, pregnancy experiences in 9-12th grade Chicago Public Schools (CPS) students and identify teens at highest risk based on gender, grade-level, race, ethnicity, and sexual orientation.

METHODS

Secondary data analysis of the 2017 CPS high school Youth Risk Behavior Survey was conducted.

RESULTS

The survey response rate was 73% (n = 1,883). 4.9% (n = 91) of CPS students in grades 9 - 12 reported a pregnancy experience, and 1.9% (n = 34) reported being "unsure" of a pregnancy experience. Statistically significant differences in the likelihood of self-reporting a pregnancy experience were found based on grade level (p = .000), race (p = .023), and sexual orientation (p = .000).

CONCLUSION

While risk for a teen pregnancy experience varies across all groups, public health nurses can use YRBS data to better understand pregnancy risk in the populations they serve and can leverage core competencies, and robust community relationships to adapt, implement and evaluate evidence-based teen pregnancy prevention programs for maximum impact on teens at greatest risk.
