This study investigated the contributions of parent, infant, and contextual variables to the prediction of maternal ratings of infant temperament. Between the time when they gave birth and six months after the birth, 104 mothers completed measures of parenting attitudes, maternal anxiety and depression, family social support, demographic information, maternal self-efficacy, and infant crying and fussiness. Maternal ratings and impressions of infant temperament were assessed at six months after birth. The ratings concerned specific infant behaviors, while the impressions concerned the mother's perceptions of her infant compared to other infants of the same age. Results indicated that maternal reports of support and anxiety at birth, self-efficacy at four months, and infant fussiness at two months correlated with maternal ratings of infant temperament at six months. Variables that correlated with maternal impressions of infant temperamental difficulty at six months included maternal age; maternal support, depression, and self-efficacy at four months; and maternal anxiety at birth. Regression analyses revealed a different set of predictor variables for maternal ratings and impressions of infant temperament at six months. Seven references are cited. (Author/BC)
