Evaluations of a large federally funded sexual risk avoidance education (SRAE) efforts in the USA have not been widely reported in the wake of funding cuts. The purpose of this study is to report results from a broad set of programmes to demonstrate the breadth of field effectiveness of these programmes. Twenty-seven separate community-based SRAE programmes were evaluated from 2005 to 2010, comprising 74 separate evaluations and involving over 96,000 young people. Pre- to post-effect sizes on key attitudinal predictors of sexual activity were analysed using meta-analytic techniques, both individually and as an average composite score. The standardised change score effect size on the composite measure were small and statistically significant (d = 0.20, k = 75, p < 0.001), as were effects on individual measures (d = 0.15-0.31). Programmes using a single curriculum showed greater results than those using their own blend of two or more curricula. As a group, this large body of field implementations of SRAE appears to have produced modest but statistically significant effects on key predictors of sexual activity in youth.
