Using data from a sample of 150 Native American mothers of a child 6 to 15 years old, this study examined the relations between and among mothers' gambling, parenting in the home environment, social supports, and child behavior problems. Respondents were recruited from a tribal casino on a Great Lakes Indian reservation. Results indicate that behavior problems in Native American children in the context of maternal gambling were associated with greater financial strain, less adequate parenting in the home environment, and the child's age. However, these results were conditioned by frequency of mother's gambling, amount of social support from family available to the mother, and child's gender. Implications of these findings for policy, practice, and future research are discussed.
