The purpose of this study was to investigate the effects of maternal employment on child development and family functioning for families with preterm infants. Data were collected in the family's home (N = 67) when the infant was 3, 9, and 12 months of age. Maternal employment at 3 months had little effect on 9-and 12-month child mental or psychomotor development or on family cohesion, adaptability, or satisfaction. Maternal employment attitude/behavior consistency was a significant predictor of psychomotor development. Choice in the employment decision at 3 months was positively related to both mental and psychomotor development at 9 and 12 months for nonemployed mothers.The decade of the 1980s witnessed a dramatic increase in the number of employed mothers with young children. Indeed, nearly 50% of married women with children under 3 years old are employed (Shank, 1988). Although some researchers believe that maternal employment is a stressful situation for children (Barglow, Vaughn, & Molitor, 1987;Belsky & Eggebeen, 1991), the effects of this potential stressor with children born prematurely have not been studied. Research with healthy children may not be applicable to prematurely born children for several reasons. First, preterm infants are at increased risk for developmental delay and may be more sensitive to stressful environmental conditions than healthy children (Tobey & Schraeder, 1990). Second, family environments for preterm infants may be different than those for full-term infants because of increased caretaking demands and stressors. The purpose of this study was to investigate the effects of maternal employment on the family and on the mental and motor development of preterm infants at 9 and 12 months of age.Because of concern for the development and wellbeing of the child with an employed mother, a significant amount of research regarding the impact of maternal employment for healthy children has been conducted; however, the results are conflicting. Some investigators report negative effects of maternal employment on attachment (Barglow et al., 1987;Belsky & Rovine, 1988;Schwarz, 1983), mother-child interaction (Cohen, 1978;Field, Stoller, Vega-Lahr, Scafidi, & Goldstein, 1986), and cognitive development (Cohen, 1978;Schacter, 1981). Others report either no effects or positive effects on attachment (Easterbrooks & Goldberg, 1985;Hock, 1980;Owen, Easterbrooks, Chase-Lansdale, & Goldberg, 1984), mother-child interaction (Schubert, Bradley-Johnson, & Nuttal, 1980) (Doyle, 1975;Hock, 1980;Stith & Davis, 1984). These conflicting results suggest that the mechanism by which maternal employment may affect the child is complex, and may be influenced by other variables.Two factors that may affect the relationship between maternal employment and child outcomes have been identified: timing of the mother's return to employment (Benn, 1986) and attitudes of the mother that conflict with her employment status (Hock, DeMeis, & McBride, 1987). Popular belief places importance on the mother's staying home w...
