Type of day-care and preschool intellectual development in disadvantaged children. Parent training of toddlers in day care in low-income urban communities.
Levels and patterns of intellectual development of 3 groups of socioeconomically disadvantaged children were compared. The groups consisted of (1) children who were randomly assigned to receive extensive university-based intervention group day-care, (2) children whose parents placed them in community day-care centers for varying amounts of time, or (3) children whose parents chose little to no center-based day-care for their children. Two repeated-measures analyses of variance were performed to identify possible day-care effects on IQ level and on patterns of infant and preschool cognitive development. The results suggest that quality community day-care, as well as intervention day-care, may positively change both the level and pattern of preschool intellectual development of socioeconomically disadvantaged children. The authors tested a 12-week parent training program with parents (n = 208) and teachers (n = 77) of 2-3-year-olds in day care centers serving low-income families of color in Chicago. Eleven centers were randomly assigned to 1 of 4 conditions: (a) parent and teacher training (PT + TT), (b) parent training (PT), (c) teacher training (TT), and (d) waiting list control (C). After controlling for parent stress, PT and PT + TT parents reported higher self-efficacy and less coercive discipline and were observed to have more positive behaviors than C and TT parents. Among toddlers in high-risk behavior problem groups, toddlers in the experimental conditions showed greater improvement than controls. Most effects were retained 1 year later. Benefits were greatest when parents directly received training.
Day care has beneficial effect on children's development, school success and adult life patterns. To date, all randomised trials have been conducted among disadvantaged populations in the USA. The extent to which the results are generaliseable to other cultures and socioeconomic groups has yet to be evaluated.
