摘要:This Campbell systematic review assesses the effectiveness of home‐based child development interventions in improving children's developmental outcomes. The review summarises findings from seven studies. Two of the studies were undertaken in the US, one in Canada, one in Jamaica, one in Ireland, one in an unreported location and one in Bermuda. The nature of the evidence makes it difficult to assess the impact on child cognitive development. Evidence synthesis of four of the seven studies finds no effect. But evidence from the other three studies cannot be combined, so the overall finding is inconclusive. Adverse outcomes for parents (for example, disempowerment) were not reported in any of the seven studies, so no conclusion can be reached. The evidence did not allow conclusions to be reached for secondary outcomes such as child physical development and parenting behaviour.
