A comparison of temperament and maternal bother in infants with and without colic.

This descriptive, retrospective study compared the temperament styles of 25 4- to 8-month-old infants who had colic with the temperament styles of 30 infants of similar age without colic. Infant temperament style was characterized by the mother's ratings of her infant's behavioral style. The degree of bother that the mother experienced in relationship to her infant's temperament also was examined. Results indicated that mothers of infants with colic rated their infants' temperaments differently than mothers of infants without colic in the temperament dimensions of activity and mood. Mothers of infants with colic were more bothered by the infants' temperament dimension of mood than were mothers of infants without colic. More infants in the colic group were characterized as difficult than were infants in the noncolic group. Individual temperament characteristics should be considered in the differential diagnosis of primary excessive crying (colic) during the newborn and infant periods.
