Families were recruited using birth announcements when infants were 5–6 months old; 57% male; 51% first born. Assessment of risk factors Demographic and family factors, child-parent interaction, child cognition and temperament were assessed at 6, 13 and 24 months and between 3–8 years of age using home observation, maternal report and laboratory tests.
