The purpose of this research was to conduct psychometric analysis of a adaptive behavior
assessment instrument, being developed to identify overall levels of adaptive behaviors and
characteristics of elementary school children. The target population for the study are 699 children with the age distribution of 7 to 12 from elementary school which located in Seoul, Daejeon, Choongnam, Kyunggi. As the results of the data analysis, Primary knowledge(concept of knowledge) and vocational skill subdomains are different relatively. Explorations of item discrimination yielded evidence of content validity. That means these items well organized by groups. The half-spilt reliability was between .68 and .97. Cronbach α was between .67 and .96.
Exploratory factor analysis of subscale variables produces one factor solution. AMOS 5 was used for confirmatory factor analysis. Followed AMOS three factor model was less parsimonious than one factor model, but the former was more fitted than the latter.
