Whole-county Triple P rollout cut substantiated maltreatment by twenty-two percent

Evidence

The outcomes were measured not from self-report parenting surveys but from administrative records: substantiated child maltreatment cases per ten thousand children, child maltreatment hospitalizations, and out-of-home placement rates. These are the bluntest possible population-level measures — the outcomes that register only the most severe cases, filtered through systems that typically undercount rather than overcount. Counties randomized to Triple P showed reductions in all three measures compared to control counties over the two-year follow-up period: roughly twenty-two percent fewer substantiated maltreatment cases, twelve percent fewer maltreatment hospitalizations, and eighteen percent fewer out-of-home placements. — , The Rod and the Child, 7186
