Abstract

In this study, psychometric properties of scale ABS-RC:2 in a Spanish context are analyzed. This scale assesses adaptive behavior in adults with intellectual disabilities to determine their diagnosis, classification and supportive needs. The scale was applied to 198 Spanish with intellectual disabilities between the ages of 18-69 (M=41, 8 DE=11, 7). First, the internal consistency was analyzed by Cronbachs Alpha. Pearsons correlation to obtain test-raters indexes, inter-raters, the criterion validity and items intercorrelation. Then, the factor analysis was performed extracting components and making with Varimax rotation method. Results show a suitable validity and reliability. The scale domains are solid and the five-factors structure looks like the original versión. The adaptation seems to fit perfectly to assess the adaptive behavior and to establish necessary supports.
