SUMMARY
The internal consistency reliability and structure-related validity of the Lithuanian version of the Acceptance of Disability Scale – Revised (ADS-R), a 32-item instrument originally developed to assess an individual’s adaptation to disability, was the focus of the research study. The translated instrument was completed by 274 mobility impaired individuals aged from 18 to 80. In this pilot study, it was found that the Lithuanian version of ADS-R had preliminary sufficient internal consistency reliability and structure-related validity similar to those reported by the authors of the original instrument. However, this Lithuanian version still needs further studies with a larger sample and more specific disability representation for exploring the psychometric properties more thoroughly. Nevertheless, in that there are few instruments on adaptation that have already been translated and used with the Lithuanian population, the authors believe that this pilot study is a very important first step in the process of creating a valid and reliable instrument.
