Abstract:
ObjectiveTo analyze the reliability and validity of Chinese version of Dysarthria Impact Profile (DIP) in assessment of the psychosocial impact of dysarthria in Parkinson's disease (PD). MethodsFrom May, 2021 to March, 2022, 43 PD patients from Department of Rehabilitation Medicine, the First Affiliated Hospital of Sun Yat-sen University were selected, and 43 age matched healthy controls were enrolled. The process of translation and adaptation was used to develop the Chinese version of DIP, and two groups were evaluated. The internal consistency reliability and intra-rater reliability were analyzed as well as the correlation between each item and its subscale, DIP scores to the Voice Handicap Index (VHI) and 36-item Short Form Health Survey (SF-36). DIP scores of two groups were compared. ResultsThe Cronbach's α was 0.732 to 0.942. The intra-rater correlation coefficient of subsection four was the highest (r = 0.670, P < 0.001). The correlation coefficients were 0.315 to 0.871, which were correlated (P < 0.05), except items 1, 6, 11 of subsection three and item 11 of subsection four. The correlation coefficient between DIP and VHI was -0.821 (P < 0.01), and it was 0.684 (P < 0.01) between DIP and SF-36. DIP scores were significant different between PD patients and the control group (P < 0.01). ConclusionThe Chinese version of DIP shows good reliability and validity, and can be used as a tool to measure the psychosocial impact of dysarthria in PD patients.
