The relationship between residential mobility, parental stress, and parenting is explored using a model based on the Family Stress Model. The roles of social support within this model are also explored. A secondary data analysis of the Fragile Families Child Wellbeing Study was conducted, providing a sample size of 4,300 families. The analyses did not support the indirect relationships hypothesized based on the FSM or stress buffering theories. However, residential mobility and parental stress had a direct effect on harsh parenting behaviors. Residential mobility was also found to reduce social support.
