Note. The following covariates, measured at or prior to study entry, were included in both the subgroup and interaction regression models: gender, age, race/ethnicity, marital status, high school or GED diploma, first-time welfare applicant, employment prior to random assignment (RA), earnings in year prior to RA, earnings in year prior to RA squared, earnings in quarter prior to RA, Aid to Families with Dependent Children (AFDC) receipt prior to RA, food stamp receipt prior to RA, number of children in the household, and age of youngest child. TANF = Temporary Assistance for Needy Families.

This model includes only those considered to be at high risk of hitting the time limit (N = 637).

This model includes all members with a time-limit risk index (N = 2,565).
