Promoting sensitive parenting in 'at-risk' mothers and fathers: A UK outcome study of Mellow Babies, a group-based early intervention program for parents and their babies.

This is the first prospective study to explore MB participation for both mothers and fathers and to indicate engagement and potential benefits specifically for 'at-risk' parents. Findings further demonstrate the effectiveness of MB as an early intervention program for parents experiencing psychosocial difficulties. Replication by studies using a contrast or control group also incorporating follow-up data would further improve the evidence base for MB.
