The Arabic psychosocial impact of assistive devices scale: Development, translation, and evaluation.

ABSTRACT

This paper describes the development, translation, and early evaluation of the Arabic Psychosocial Impact of Assistive Devices Scale (AR-PIADS), an outcome measure instrument for the subjective impact of Assistive Technology on a person with a disabilities' quality of life. Developing the AR = PIADS instrument involved forward and backward translation by two independent teams of bilingual, Arabic-English speakers (n = 5) and a quality and usability review by a panel of people with disabilities (n = 18). The emergent version was evaluated with a group of experienced Arabic-speaking Assistive Technology users (n = 67) for its psychometric properties. Initial results demonstrate a favorable comparison for 16 of the 26 questionnaire items with scores recorded for the original, English language version. Internal consistency, measured using Cronbach's alpha, yielded a range of 0.97-0.99 for AR-PIADS while the new instrument's reliability was assessed using an intraclass correlation coefficient resulting in scores within the range of 0.86-0.97 for the overall instrument. Despite these positive results however, the translation process did highlight a number of challenges with language and cultural interpretation of the translated instrument. This suggests that further work is warranted to explore its utility in service provision.
