Input: We included eight studies with 513 participants, providing a total of 47 comparisons of outcome between intervention and control conditions. Nineteen comparisons were statistically significant, all favouring the intervention group. We conducted nine meta-analyses using data from four studies in total (each meta-analysis included data from two studies). Four meta-analyses showed statistically significant findings favouring the intervention group for the following outcomes: parent responsiveness to the child post-intervention (SMD -0.91, 95% CI -1.52 to -0.30, P = 0.04); infant responsiveness to mother at follow-up (SMD -0.65, 95% CI -1.25 to -0.06, P = 0.03); and an overall measure of parent-child interactions post-intervention (SMD -0.71, 95% CI -1.31 to -0.11, P = 0.02), and at follow-up (SMD -0.90, 95% CI -1.51 to -0.30, P = 0.004). The results of the remaining five meta-analyses were inconclusive. Variation in the measures used, the included populations and interventions, and the risk of bias within the included studies limit the conclusions that can be reached. The findings provide some evidence to suggest that parenting programmes may be effective in improving a number of aspects of parent-child interaction both in the short- and long-term, but further research is now needed.
Output:

The findings are based on eight studies measuring a variety of outcomes, using a range of standardised measures. It was possible to combine results (meta-analysis) for nine comparisons. Results from four of these meta-analyses suggest that parenting programmes may be effective in improving parent responsiveness to the child, and parent-child interaction, both post-intervention and at follow-up. Infant responsiveness to the mother also showed improvement at follow-up. The results of the other five meta-analyses we carried out were inconclusive. Further rigorous research is needed that provides both short- and long-term follow-up of the children of teenage parents, and that assesses the benefits of parenting programmes for young fathers as well as young mothers.
