Abstract
The aim of our study was to assess the longitudinal validity of the 8‐item Parkinson's Disease Questionnaire (PDQ‐8) in terms of responsiveness and test–retest reliability and to determine the minimally important difference (MID) for PDQ‐8 using the anchor‐based approach in Asians with Parkinson's disease (PD). A consecutive sample of PD patients attending a tertiary neuroscience clinic in Singapore completed the English or Chinese version of PDQ‐8 twice during two different clinic visits. During the second visit, patients were also asked to rate their changes in health in general, PD severity, and overall impact of PD since at the time of their first visit 1 year ago using a 5‐point response scale. A total of 96 patients participated in the study. For patients who reported changed conditions in the second visit, responsiveness measured by Cohen's effect size, standardized response mean, and Guyatt's responsiveness index ranged from 0.21 to 0.68. The intraclass correlation coefficient values calculated using patients reporting no change in health or PD status ranged from 0.64 to 0.76. The mean changed PDQ‐8 summary index score in patients who reported that their health or PD status worsened only “a little bit” ranged from 5.8 to 7.4 points. Our current results show that PDQ‐8 is a longitudinally reliable and responsive measure for assessing the health‐related quality of life in patients with PD. The MID of the PDQ‐8 estimated in the study will further support the use of this instrument in both clinical research and practice. © 2008 Movement Disorder Society
