Infant temperament and noncompliant behavior at four years: a longitudinal study.

Noncompliant behavior in early childhood (i.e., exaggerated, but age-appropriate negativism) has been inadequately studied. This longitudinal study explores preschool temperament and maternal behavior as current correlates of negativistic behavior at age 4, and early maternal characteristics and infant temperament as etiological variables in the production of negativism. Longitudinal evidence was collected from 62 mother-child dyads, representative of all social classes. This evidence included home observations of maternal and child behavior at 4 years, a temperament questionnaire at 4 years, a questionnaire about infant temperament, and observational and interview measures at various stages from birth to 3 years, of infant behavior and maternal characteristics. The findings suggest that infant and childhood temperament (especially the degree of infant fussiness) are highly predictive of physical noncompliance, and that physical noncompliance is unrelated to maternal or demographic variables. A combination of maternal variables including warmth, closeness, and verbal directiveness, both positive and negative, as well as child variables, predict verbal noncompliance. Demographic variables, temperament, and maternal attitudes predict passive noncompliance. Noncompliance is viewed as a complex phenomenon in which constitutional and environmental variables interact.
