An examination of the relationship between child care subsidies and child care-related work disruptions that affect mothers' ability to maintain steady employment and work productively, including considerations of whether this relationship is mediated by variables that affect the type of care chosen, and whether subsidies impact the desire to change child care arrangements. The study applies cross-sectional and change regression models and path analysis to two samples: (1) a sample, collected in 2005-2006, of 40 low-income employed mothers who were interviewed twice--once while on the wait list for child care subsidies, and again eight months later, when the majority had subsequently received a subsidy--allowing for a quasi-experimental research design; and (2) a sample of predominately unmarried mothers with children aged 1-3 years from the Fragile Families and Child Well-Being study.
