Temperament in infants born prematurely

Area of Science:

• Developmental Psychology
• Neonatal Studies
• Infant Behavior

Background:

• Prematurity is often considered a risk factor for infant social interaction challenges.
• Understanding infant temperament is crucial for assessing developmental trajectories.

Purpose of the Study:

• To investigate if prematurity influences infant temperament.
• To compare the temperament profiles of premature infants with those born at term.

Main Methods:

• The Infant Temperament Questionnaire was adapted for an Australian population.
• Mothers of premature infants (≤36 weeks gestation) and a control group of full-term infants completed the questionnaire.
• Temperament dimensions and maternal global ratings were analyzed.

Main Results:

• No significant differences in any of the nine temperament dimensions were found between premature and full-term infants.
• The distribution of "easy," "difficult," and "slow to warm up" infants was similar in both groups.
• Results were consistent even when analyzing infants with less than 33 weeks gestation.

Conclusions:

• Infants born prematurely exhibit similar temperament profiles to those born at term by 4 to 8 months corrected age.
• Prematurity does not appear to be a significant risk factor for altered infant temperament in this age range.
