Controlled trial of the short- and long-term effect of psychological treatment of post-partum depression. 2. Impact on the mother-child relationship and child outcome

BackgroundPostnatal depression is associated with adverse child cognitive and socio-emotional outcome. It is not known whether psychological treatment affects the quality of the mother–child relationship and child outcome.AimsTo evaluate the effect of three psychological treatments on the mother–child relationship and child outcome.MethodWomen with post-partum depression (n=193) were assigned randomly to routine primary care, non-directive counselling, cognitive–behavioural therapy or psychodynamic therapy. The women and their children were assessed at 4.5, 18 and 60 months post-partum.ResultsIndications of a positive benefit were limited. All three treatments had a significant benefit on maternal reports of early difficulties in relationships with the infants; counselling gave better infant emotional and behaviour ratings at 18 months and more sensitive early mother–infant interactions. The treatments had no significant impact on maternal management of early infant behaviour problems, security of infant–mother attachment, infant cognitive development or any child outcome at 5 years.ConclusionsEarly intervention was of short-term benefit to the mother–child relationship and infant behaviour problems. More-prolonged intervention may be needed. Health visitors could deliver this.
