The links between single mothers' employment patterns and change over time in the well-being of the mothers' adolescent children were investigated using the National Longitudinal Survey of Youth. Adolescents were ages 14 to 16 at baseline, and they and their mothers were followed for 2 years. Relative to being continuously employed in a good job, findings suggest that adolescents whose mothers lose a job without regaining employment show declines in mastery and self-esteem, those whose mothers are continuously employed in a bad job show an increased likelihood of grade repetition, and those whose mothers are either persistently unemployed or lose more than one job show an increased likelihood of school dropout. These effects are not explained by concomitant changes in family income.
