Behaviour problems in pre-school children: family and social factors.

In a group of 99 three-year-old children with behaviour problems identified in an epidemiological survey, family and social factors were compared with those in a group of controls. Behaviour problems were significantly associated with a strained marital relationship between parents, with social stresses and with type of housing. There was a high rate of maternal depression in both problem and control groups. The interaction between a behaviour problem in a young child, maternal mental health and social factors is discussed.
