Infant Assessment Unit - Infant Behavior Ratings

Title

Infant Assessment Unit - Infant Behavior Ratings

Description

The Infant Assessment Unit (IAU) was part of the Longitudinal Cohort Study. The objective of the IAU was to observe how prenatal and postnatal conditions affect the health and cognitive functioning of infants during the first year of life. Consisting of several instruments, the IAU sought to measure infant cognition and quantify the experiences of the sampled infants from Cohort 0 during their first 12 months of life. Additionally, the IAU examined the circumstances surrounding the mother's pregnancy and the subsequent care received by the infant. The IAU was administered to subjects or primary caregivers in Cohort 0 only in Wave 1 of the LCS.

The Infant Behavior Ratings (IBR) measure (PDF 2.7MG) was included in the IAU to evaluate infant temperament. The IBR rated the infant on a number of observed behaviors and also rated the validity of the other IAU measures. It was completed by the research assistant with one response stemming from comments from the subject's primary caregiver.
