This study explores the impact of a Head Start add-on programme, a matrix of services for parents which provides educational and vocational supports, on maternal depression and children's behaviour in Latino families. We hypothesise that after having completed training, parents who participated in the add-on programme would have lower levels of reported depression than parents receiving Head Start services alone. It was also hypothesised that decreased levels of reported depression would be related to increases in children's social skills and reductions in their behaviour problems. Fifty Latino children from a local Head Start programme and their primary caregivers participated in the study. Results indicate that intervention group mothers had significantly lower levels of reported depression when compared to mothers who received regular services. Children's social skills appeared to increase and their behaviour problems decrease, regardless of whether their parents were involved in self-sufficiency promoting activities in the programme.
