Examining the Structure of a Modified Version of the Acceptance of Disability Scale-Revised for Thai Disable Individuals

Abstract

This study examined the psychometric properties of the modified version of Acceptance of Disability Scale-Revised (ADS-R) for Thai individuals with disabilities. The scale contains 26 items. Participants were 204 individuals with physical disabilities who attended physical rehabilitation centers or vocational rehabilitation centers for people with disabilities across the country and were on rehabilitation phase. Principal components analysis was performed to examine underlying factorial structure of the Thai version of ADS. Cronbach’ s alpha coefficients were computed to examine the scale’ s reliability. The findings revealed that the modified version, 26-item ADS-R yielded four components ( Transformation, Enlargement, Containment, and Subordination) , accounting for 59. 17% of the total variance. All items loaded significantly onto their respective factors (loading factors ranged from.40 to.90). The modified version, 26-item ADS-R demonstrated good reliability with Cronbach's alpha of.92 for the total scale and.84, 81,.91 and.83 for its four components, respectively.
