Abstract
PURPOSE: In this paper the history of the development and validation of the PIADS is reviewed. Assistive devices (ADs) are extremely prevalent forms of health care intervention for persons who have a disability. There is a consensus that the AD field needs a reliable and valid measure of how users perceive the impact of ADs on their quality of life (QoL) and sense of well-being. The Psychosocial Impact of Assistive Devices Scale (PIADS) is a 26 item self-rating scale designed to fill this measurement gap. The challenges that we encountered are described in attempting to adequately conceptualize QOL impact, and operationalize it in a measure suitable for use with virtually all forms of AD. Current efforts to extend the validation of the PIADS are summarized. CONCLUSIONS: The study concludes by suggesting directions for future research and development of the scale. They include a richer examination of its conceptual relationships to other health care and rehabilitation outcome measures, and further investigation of its clinical utility. The PIADS is a reliable and valid tool that appears to have very significant power to predict AD abandonment and retention. It can and should be used both deductively and inductively to build, discover and test theory about the psychosocial impact of assistive technology.
