Impacts of Four Title V, Section 510 Abstinence Education Programs. Subgroup Impacts

04/13/2007

 

  • For several subgroups examined, programs show no consistent evidence of impacts on sexual abstinence or other behavioral measures.

Estimated impacts across a series of subgroups, summarized in Appendix D, display few statistically significant impacts on any of the behavioral outcomes examined above for the full sample.  Take, for example, the subgroup defined by whether youth have relatively high or low support for abstinence at baseline.  As discussed later in Chapter VI, this measure proves to be an important predictor of sexual abstinence, and it might also be expected to affect the way that youth respond to program messages.  However, as seen in Table IV.5, this is not the case.  Differences between program and control group youth are small in both subgroups defined by the measure and are not statistically significant.  A similar pattern of results is evident for other subgroups, including gender, religiosity, television viewing, and enrollment cohort, with a mix of positive and negative impact estimates that are small and rarely statistically significant (all shown in Appendix D).
