Family Instability and Children's Early Problem Behavior

This study investigated the association between family instability and children's problem behavior during the transition to first grade. In a sample (n = 1,015) drawn from the NICHD Study of Early Child Care and Youth Development, we found that a quarter of sample members experienced at least one family transition between birth and age 6. Instability was also related to family structure at birth: those born into cohabiting parent families experienced the most instability, followed by those born into single mother families and finally, those in two-biological married parent families. Children who experienced instability had higher teacher and observer reports of problem behaviors than those from stable family structures. Finally, differences in problem behavior associated with family instability varied by family structure at birth and the emotional, social and material resources in the family.
