The adaptive ability performance test (ADAPT): A factor analytic study in clients with intellectual disabilities

Abstract

Background: The adaptive ability performance test (ADAPT) was developed to assess adaptive skills in individuals with intellectual disabilities and borderline intellectual functioning, with or without mental disorders. As a follow-up to earlier research on the ADAPT, a factor analytic study was conducted.Method: One thousand and sixty six ADAPTs from clients with (suspected) intellectual disabilities or borderline intellectual functioning and 129 ADAPTs from participants from the general population were collected along with other characteristics (e.g., IQ, psychiatric classifications, living situation).Results: An exploratory factor analysis (EFA) was performed and resulted in good fit indices. Subsequent confirmatory factor analysis (CFA) and multigroup CFA showed acceptable to good fit indices. This resulted in an instrument with eight factors and 62 items. Conclusion:Factor analytic results suggest that the ADAPT is a valid instrument that measures adaptive skills in individuals with intellectual disabilities or borderline intellectual functioning.

Assessment of adaptive behavior in people with intellectual disabilities: Design and development of a new test battery

“…The proposed analyses are not usually carried out during the design nor adaptation of an adaptive behavior scale; even when demonstrating a robust internal structure is imperative to assert validity only a few studies report so [ 25 ]; moreover, invariance analyses are necessary in order to make fair comparisons among population groups.…”

“…Moreover, the Adaptive Ability Performance Test (ADAPT) measures adaptive functioning in adults (16–82 years old) and encompasses contemporary adaptive skills like internet banking, mobile phones, and social media; this test showed satisfactory validity and reliability [ 23 , 25 ]. Lastly, the Functional Screening Tool for Persons with Intellectual Disabilities (FST-ID), which is a short rapid test (17 items) with high psychometric properties [ 24 ].…”

Bayesian Regularized SEM: Current Capabilities and Constraints

“…To obtain a realistic data set that can be freely shared online, I generated a data set based on the observed covariance matrix from a study on the adaptive ability performance test (ADAPT; [85]). The ADAPT consists of 65 items intended to assess adaptive skills in individuals with intellectual disabilities and borderline intellectual functioning across three domains (conceptual, social, and practical).…”

Construction and metric properties of a new instrument to measure adaptive behaviour in people with intellectual disabilities. Peruvian context.

“…Lastly, two new adapted instruments showed up, the Adaptive Ability Performance Test (ADAPT) that measures adaptive functioning in adult people (16-82 years old) and encompasses contemporary adaptive skills like internet banking, mobile phones, and social media. This test showed satisfactory validity and reliability (24,25) and the Functional Screening Tool for individuals with Intellectual disabilities (FST-ID) which is a rapid test (17 items) with high psychometric properties (26).…”
