The aim of this study was to assess the association between the length
of maternity leave and the quality of mother-infant interactions; 198
employed mothers of 4-month-old infants were interviewed and videotap
ed in their homes during a feeding time. Hierarchical multiple regress
ion analyses indicated a direct association between shorter length of
leave and more negative affect and behavior in maternal interactions w
ith their infants. Infant and mother stresser/protective variables add
ed significantly in predicting the quality of the mother-infant relati
onship. There were also significant interaction effects between the le
ngth of leave and these variables. Mothers who either reported more de
pressive symptoms or who perceived their infant as having a more diffi
cult temperament and who had shorter leaves, compared with mothers who
had longer leaves, were observed to express less positive affect, sen
sitivity, and responsiveness in interactions with their infants. The p
ublic policy implications of the relation between length of maternity
leave, maternal and infant individual differences, and the quality of
mother-infant interactions are discussed.
