Results of models examining associations among maternal nonstandard work schedules and possible mediators when the focal child is 15, 24, and 36 months of age.

Models control for the effects of maternal age, education, race/ethnicity, marital status at 36 months, weeks of leave from primary job, cumulative poverty status, child's gender, child's temperament, child's birth order, and recruitment site. Models for 24-month outcomes control for previous assessment at 15 months, and models for 36-month outcomes control for assessments at 15 and 24 months.

^aAfter 1st year represents entrance into a NS job at either 15 or 24 for the 24-month analysis, and entrance into a NS job at 15, 24, or 36 months for the 36-month analysis.
