ABSTRACT
The Psychosocial Impact of Assistive Devices Scale (PIADS) is commonly used to assess the psychosocial effects of an assistive device. Given its growing use, an appraisal of the evidence regarding its psychometric properties is required. We conduct a systematic review using validated critical appraisal scales to analyze both the quality and content of the evidence on the psychometric properties of the PIADS. PubMed/Medline, Embase, and CINAHL were systematically searched for identification of studies. Two independent reviewers appraised the retrieved studies using MacDermid and COSMIN-RoB checklists, and extracted data regarding the psychometric measurements reported. MacDermid scores showed that 8 out of 11 studies were, at least, of good methodological quality. COSMIN-RoB scores ranged from inadequate to very good. Except criterion and construct validity, which have presented a moderate level of evidence, the other psychometric properties assessed have demonstrated a high level of evidence. Cross‐cultural validity, measurement error, and responsiveness have not been studied. Few studies have yet evaluated the psychometric properties of the PIADS. However, the quality of the evidence that they provide is mostly adequate. Therefore, this review supports the use of the PIADS, which has overall good psychometric properties.
