This study examined the nature of Head Start mothers' warm, autonomy supportive, consistent, and harsh parenting practices. The measure of interest was the Child Rearing Practices Scale (Block, 1965). Results show that this measure can be used among Head Start mothers, but that a two-factor solution might be most appropriate. In general, mothers are very supportive of children. Overall, there is little change among most families, but there are reductions in problematic parenting practices among those with high initial levels of these behaviors.
