Sociocultural variability in infant temperament ratings.

The interaction between the temperament of children and their caretaking environment is thought to be an important factor in the etiology of childhood behavior deviance. Most recent research in infant temperament has used a maternal questionnaire. Scores from these questionnaires have been subject to low concurrent validity. Also, there have been indications that maternal characteristics such as anxiety level influence child temperament ratings. The present study examined mother characteristics, child behavior, and mother's temperament ratings when their babies were 4 months old. The social status, anxiety level, the mental health status of the mother were all related to temperament ratings on the Carey Infant Temperament Questionnaire. However, child behavior measured in the home and laboratory were sporadically related to temperament, and these relations were of small magnitude. Hierarchical multiple regression analysis demonstrated that mother effects were powerful than child effects. These results supported the notion that individual differences in mothers, rather than differences in infants, may be the major contributor to early ratings of temperament.
