This preliminary study aimed to adapt the Dysarthria Impact Profile (DIP) in French and to confirm its relevance for the assessment of the psychosocial impact of dysarthria in Parkinson's disease (PD). The DIP scale was administered to 10 people with PD and 10 age-matched control subjects. The DIP psychometric properties were calculated (discriminant validity, internal consistency, and concurrent validity), notably by using the Voice Handicap Index (VHI) for interscale comparisons. The French version of the DIP discriminated people with PD from control subjects (χ (2) test, P < 0.05). Good internal consistency was observed in both populations (Cronbach's α = 0.93 for PD people and α = 0.76 for control subjects). The DIP was highly correlated with the VHI (Spearman's ρ = -0.70, P < 0.01), confirming the external validity of the scale. There was no direct relationship between PD speech and quality of life as assessed by the Parkinson's Disease Questionnaire-39 (PDQ-39). Our preliminary data suggest that the French version of the DIP has the potential to make a useful contribution for the assessment and outcome management in acquired dysarthria for both clinicians and researchers.
本初步研究旨在将 Dysarthria Impact Profile（DIP）改编为法语，并确认其对评估帕金森病（PD）患者构音障碍的心理社会影响的相关性。该 DIP 量表被用于 10 名 PD 患者和 10 名年龄匹配的对照受试者。对 DIP 的心理测量特性进行了计算（鉴别效度、内部一致性和同时效度），特别是通过使用语音障碍指数（VHI）进行量表间比较。法语版的 DIP 能够区分 PD 患者和对照组（卡方检验，P < 0.05）。在两个群体中均观察到良好的内部一致性（PD 患者的 Cronbach's α = 0.93，对照组的 α = 0.76）。DIP 与 VHI 高度相关（Spearman 的 ρ = -0.70，P < 0.01），证实了该量表的外部有效性。PD 患者的言语与帕金森病问卷-39（PDQ-39）评估的生活质量之间没有直接关系。我们的初步数据表明，法语版的 DIP 有可能为临床医生和研究人员评估和管理获得性构音障碍提供有用的贡献。
