Infant Assessment Unit - Young Adult Self Report


Infant Assessment Unit - Young Adult Self Report


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 Young Adult Self Report (YASR) (PDF 3.1MG) was included in the IAU as a self-administered survey used to obtain information on specific aspects of the respondent's life. Included were such topics as interpersonal relationships and conflicts, tendencies toward various anti-social behaviors, and habits regarding non-medical drug and alcohol consumption. The YASR also sought to identify personality traits and behaviors that might be classified as unusual. The goal of the YASR was to obtain an overall score for each respondent, based on the answers provided, that could be used to make observations and determinations regarding his or her psychological, emotional, and behavioral health and overall quality of life. It was administered to the subject's primary caregiver.
