Abstract

Abstract : Aim: The present study sought to make a cross‐cultural adaptation of the Dysarthria Impact Profile (DIP) for European Portuguese (EP) and validate it for use in Parkinson's disease (PD) patients. Methods: The cross‐cultural adaptation was carried out in accordance with the guidelines. The EP version of the DIP was administered to 80 people with PD, and 30 sex‐ and age‐matched control participants. Psychometric properties, acceptability, feasibility reliability (internal consistency and intrarater agreement) and validity (construct, convergent and known‐groups validity) were assessed using other assessment tools (motor disability and impairment, and voice impact). Results: Overall, the EP‐DIP final version has the same conceptual meaning, semantics, idiomatic and score equivalences as the original version. Statistical analyses showed adequate feasibility (missing data <5%), good acceptability (ceiling or floor effects <15%; high requests of assistance to complete the questionnaire), satisfactory internal consistency (Cronbach's α = 0.9), weak‐to‐moderate intrarater reliability, good construct validity, strong convergent validity (with the Voice Handicap Index; Spearman's P = −0.8) and good known‐groups validity (between those with PD and control participants). Conclusions: The EP‐DIP version displays the salient features of a valid patient‐based assessment tool used to measure the psychosocial impact of slight‐to‐mild dysarthria in people with PD.Geriatr Gerontol Int 2018; 18: 767–774 .
