Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2-11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (k = 156, n = 13,378, M = 2-10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones.
有人强烈主张对儿童问题进行早期干预，称早期干预比晚期干预更有效，因为大脑的可塑性更强，成本更低。然而，试验中几乎没有证据支持这一假设，因此我们在两项具有互补优势的强大、最先进的荟萃分析中对此进行了检验：（a）对欧洲 Incredible Years 育儿干预试验的个体参与者数据（IPD）荟萃分析（k=13，n=1696；年龄=2-11）；（b）更广泛的育儿计划（k=156，n=13378，M=2-10）降低破坏性行为的试验水平稳健方差估计荟萃分析。这两项分析都没有发现早期干预更有效的证据；针对更窄年龄范围的项目并不比一般项目更有效。
