Details
The study evaluated Plan A using a randomized controlled trial involving Black and Latina women ages 18 or 19. The women were recruited from eight health centers in California's Central Valley and the greater Oakland area. Participants were randomly assigned to either a treatment group in which participants watched the 23-minute Plan A video, or a control group in which participants watched The Toxic Life Cycle of a Cigarette, a 17-minute video about the hazards of smoking cigarettes. Surveys were administered immediately after study enrollment (baseline), and three and nine months after study enrollment.



Three months after study enrollment, the study found no statistically significant program impacts on the likelihood of getting tested for an STI in the preceding three months or on the number of times youth had sex without condoms in the preceding three months.



The study also found that nine months after study enrollment, youth who were offered the Plan A video reported having had in the past three months any type of sex (effect size = -0.09) and vaginal sex (effect size = - 0.10) without using a condom significantly fewer times than youth in the control group. Nine months after enrollment, the study did not find any statistically significant program impacts on the likelihood of getting tested for an STI in the past three months.



The study also examined program impacts on measures of current use of long-acting reversible contraception contraceptive knowledge, pregnancy risk perception, and STI risk perception. Findings for these outcomes were not considered for the review because they fell outside the scope of the review.

NA = Not available. This means the authors did not report the information in the manuscripts associated with the studies we reviewed.

a This information was not available whenever authors did not report information for the treatment and comparison groups separately on outcome means, standard deviations, and/or sample sizes.

b Authors reported that the program effect (impact) estimate is statistically significant with a p-value of less than 0.05 based on a two-tailed test.

c For some outcomes, having less of that outcome is favorable. In those cases, an effect with a negative sign is favorable to the treatment group (that is, the treatment group had a more favorable outcome than the comparison group, on average).

d An effect shows credibly estimated, statistically significant evidence whenever it has a p-value of less than 0.05 based on a two-tailed test, includes the appropriate adjustment for clustering (if applicable), and it is not based on an endogenous subgroup.
