Predicting preschool behavior problems from temperament and other variables in infancy.

There is uncertainty about the relationship between difficult temperament in infancy and reported problem behaviors later in childhood. In this study data from a large, representative community cohort (total N studied = 1583) were used to determine whether preschool behavior problems (at age 4 to 5 years) could be predicted from difficult temperament and other variables in infancy. Maternal ratings of difficult temperament on the Revised Infant Temperament Questionnaire predicted only 17.5% of those with preschool behavior problems, a percentage not significantly greater than the 14% of the total sample rated as having problems. There was some improvement in prediction when difficult temperament was added to other variables such as male sex (28%). However, mothers' overall rating of temperament was a more powerful predictor of preschool behavior problems, both alone (26.0%) and in combination with other variables such as perinatal stress (36.8%), male sex (29.5%), and non-Australian parent (29.4%). Similarly, maternal reports of infant behavior problems was a more powerful predictor of preschool behavior problems both alone (21.8%) and in combination with male sex (24.6%), low socioeconomic status (26.1%), non-Australian parent (21.8%), and nurse's overall rating of temperament (21.8%). The best consistent predictor of later problems was the combination of mothers' overall rating of temperament and maternal reports of infant behavior problems (27.0%), especially when combined with other infant variables such as perinatal stress (35.3%), male sex (31.5%), and non-Australian parent (30.0%).(ABSTRACT TRUNCATED AT 250 WORDS)
