Infant Assessment Unit - Infant Behavior Questionnaire


Infant Assessment Unit - Infant Behavior Questionnaire


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 Questionnaire (IBQ) (PDF 2.7MG) was included in the IAU to offer the primary caregiver (PC) an opportunity to assess the behavior of the infant with respect to six components of infant temperament, including fear, distress to limits, duration of orienting, soothability, activity, and laughter and smiling. The IBQ asked the PC to make these valuations based on the infant's behavior over the course of the two weeks leading up to the administration of the IBQ. For each item, PC's were given three responses from which to choose one that best described the infant's behavior. It was administered to subject's primary caregivers.
