Purpose: To estimate the effect of the Making Proud Choices! (MPC) curriculum, one of the most popular evidence-based teen pregnancy prevention curricula being implemented nationwide., Methods: A cluster randomized trial was used to assign high schools to receive the MPC program or to serve as a standard care comparison group. The study took place in 15 schools in four cities in the United States. A total of 31 clusters and over 2,800 youth (predominantly in grades 9 and 10) were assigned to condition between 2016 and 2019. Student surveys administered at baseline and approximately 9 months after baseline were used to estimate the effects of MPC on risk and protective factors (knowledge, attitudes, self-efficacy) as well as sexual behavior outcomes., Results: The evaluation showed several large, statistically significant, and favorable impacts on nearly all of the risk and protective factors for risky sexual behavior. In addition, the study found a favorable effect of MPC on reducing the number of episodes of sex in the past 3 months., Discussion: The evaluation showed that MPC, as it is commonly implemented today, has evidence of effectiveness on improving both risk and protective factors, and sexual behavior outcomes. Based on these findings, MPC will continue to be seen as an evidence-based teen pregnancy prevention program for implementation through federal grant programs., (Copyright © 2023 Society for Adolescent Health and Medicine.

Objectives: This study sought to determine the impact of Healthy Families Healthy Futures (HFHF) enhanced with Steps to Success (STS). HFHF is a structured home visiting program for teen parents in Houston that focuses on improving parenting skills and preventing child abuse. HFHF enhanced with STS includes content and activities aimed to reduce repeat pregnancies within 24 months after the first child's birth., Methods: The study team recruited 248 young mothers for the study, primarily through local health clinics and schools, and then randomly assigned them to either a treatment group that was eligible to participate in HFHF enhanced with STS or to a control group. The control group was not offered any other program through the study. Outcomes were measured by a survey administered 12 months after program intake, in five domains aligned with the program's logic model: (1) exposure to information related to program content, (2) contraception knowledge, (3) contraception use, (4) enhanced family functioning, and (5) child health and development. To estimate program impacts, we used ordinary least squares regression, controlling for demographics and baseline measures of the outcome variables, if available. We use both frequentist approaches (calculations of statistical significance) and Bayesian posterior probabilities to interpret the findings., Results: HFHF enhanced with STS significantly (p < .05) impacted exposure to information on parenting and birth control, with effects of 20.8 and 15.4 percentage points, respectively. Using Bayesian posterior probabilities, there is an 85% chance that the program had a favorable effect on these outcomes. We also calculate a probability of 77% that the program had a favorable impact on long-acting reversible contraceptive (LARC) use, but a probability of 89% that the program reduced knowledge of birth control pills; these two results were not statistically significant (p = .17 and .10, respectively)., Conclusions for Practice: These findings are primarily favorable and consistent with the program content and goals. Smaller than anticipated sample sizes due to recruitment challenges increased the chances for random error to affect the ability to detect statistically significant differences on many of our other outcomes; Bayesian posterior probabilities can therefore aid in interpreting the impact estimates. More research of this promising model is warranted.
