Input: We included seven studies, which involved 723 participants. We assessed four of the seven studies as being at high risk of bias and three had an unclear risk of bias; the quality of the evidence was difficult to assess as there was often insufficient detail reported to enable any conclusions to be drawn about the methodological rigour of the studies. Four trials involving 285 participants measured cognitive development and we synthesised these data in a meta-analysis. Compared to the control group, there was no statistically significant impact of the intervention on cognitive development (standardised mean difference (SMD) 0.30; 95% confidence interval -0.18 to 0.78). Only three studies reported socioemotional outcomes and there was insufficient data to combine into a meta-analysis. No study reported on adverse effects. This review does not provide evidence of the effectiveness of home-based interventions that are specifically targeted at improving developmental outcomes for preschool children from socially disadvantaged families. Future studies should endeavour to better document and report their methodological processes.
Output:

The purpose of this review was to look at whether home-based parenting programmes, which aim to improve child development by showing parents how to provide a better quality home environment for their child, are effective in doing so. Seven randomised controlled trials (RCTs) met the inclusion criteria for this review. It was possible to combine the results from four of the seven studies, which showed that children who received the programme did not have better cognitive development than a control group. Socioemotional development was measured in three studies but we could not combine this data to help reach a conclusion about effectiveness. None of the studies measured adverse effects. The quality of the evidence in the studies was difficult to assess due to poor reporting. More high quality research is needed.
