Infant temperament and child-rearing stress: birth order influences

The relationship between an infant's temperamental difficulty and the mother's child-rearing stress was investigated in a sample of 128 children. Children's temperament was assessed by the Revised Infant Temperament Questionnaire (RITQ) at 6-7 months, and by the Toddler Temperament Scale (TTS) at 18 months. The mothers' child-rearing stress was assessed by a self-report questionnaire. At the children's age of 18 months, mothers of difficult children reported higher child-rearing stress than mothers of easy children. Although difference in the level of child-rearing stress reflecting birth order was not evident at either 6-7 months or 18 months, the proportion of child-rearing stress which could be explained by the children's temperament was highest for mothers of first-borns when their children were 18 months old.
