Many research studies in early childhood assessment have addressed the importance of quality assessment services. Such services involve gathering information on children through direct observation of functional skills in natural settings, which requires considerable time and effort. Due to the unavailability of sufficient resources for the quality assessment services, a new approach needs to be undertaken. Current research has suggested that parent-completed screening utilizing parental knowledge about their child is valid and reliable in appraising current and observable behaviors (Bodnarchuk & Eaton, 2004; O'Neill, 2007). There has been, however, little investigation on in-depth standardized assessments completed by parents for young children aged 18 to 36 months. This study examined validity and reliability of in-depth parental report on child development with the Ages and Stages Questionnaire Inventory for Toddlers (ASQ-IT) for children aged 18-36 moths old. Fifty child-caregiver dyads were divided into two groups, non-risk and risk based on environmental factors including maternal age at the child's birth, family income, and maternal education. In examining psychometric information of the parent-completed measure, acceptable outcomes were found. Accuracy was supported by two examinations for concurrent validity; (1) the Battelle Developmental Inventory, 2nd Edition (BDI-2) administered by professionals and the ASQ-IT completed by parents (r = .63 -.83,p < .01), and (2) the same two measures completed by professionals (r = .72 -.92,p < .01). Findings of both reliability studies, test-retest reliability with the ASQ-IT completed by parents, and inter-observer reliability between parents and professionals, suggested substantial consistency, p = .79 -.93 and p = .65 -.88 respectively. In differential item functioning (DIF) (i.e., 3% of DIF items) and known-group validity analyses (p < .0005 at 36 months), the ability of the ASQ-IT to detect changes in the children's development was confirmed. Results from the social validity examining parent perception of the ASQIT completion identified efficiency of the ASQ-IT (e.g., reasonable time to complete) as well as many benefits.
