Background: Despite the frequently reported association between maternal depression and childhood psychopathological disorder, few studies have attempted to intervene with both conditions.
Aims: To evaluate the effect of group cognitive-behavioural therapy (CBT) on child behaviour problems and maternal depression in a group of women with young children.
Method: An assessor-masked, randomised placebo-controlled trial compared three treatments: CBT for depression and parenting skills enhancement; a mothers' support group; and no intervention. An epidemiological (general population) sample was recruited.
Results: Analysis showed no significant difference between the groups. Within-group comparison suggested that at the end of treatment and at 6-month and 12-month follow-up, child problems and maternal depression had improved significantly in the CBT group.
Conclusions: There was no statistically significant difference between groups. Both contact interventions seemed to provide some benefits to mothers with depression, with a possibly improved outcome resulting from CBT for children with behavioural problems. The results must be treated with caution.
