The Barthel Index (BI) is used in Italy to measure the severity of disability and to identify patients suitable for admission to rehabilitation units. The objective of this psychometric study was to validate the Italian version of the BI in a population of patients with Parkinson's disease (PD). The study was conducted at three neurological and rehabilitation centres in Rome, Italy. The BI was administered to outpatients with PD. The reliability of the scale was assessed using Cronbach's alpha for internal consistency; the intra-class correlation coefficient (ICC) was used to measure its intra- and inter-rater reliability. Pearson's correlation coefficient was calculated to evaluate its validity, comparing it with the Parkinson's disease Questionnaire (PDQ-39), the Italian version of the Geriatric Depression Scale (GDS), the Hospital Anxiety and Depression Scale (HADS), and the Short Form 36-Health Survey Questionnaire (SF-36). The BI was administered to 94 patients with PD. The psychometric properties measured were significant: Cronbach's alpha was 0.866 and the ICC for intra- and inter-rater reliability was 0.998 and 0.993, respectively. Pearson's correlation coefficient showed good correlation with the PDQ-39, GDS, HADS and SF-36 (p < 0.01). The BI is a valid and reliable tool for measuring disability in a PD population.
巴氏指数（BI）在意大利用于衡量残疾严重程度，并确定适合入住康复单元的患者。这项心理测量学研究的目的是在帕金森病（PD）患者群体中验证意大利语版的BI。该研究在意大利罗马的三个神经科和康复中心进行。BI应用于PD门诊患者。使用克朗巴哈系数评估量表的内部一致性可靠性；组内相关系数（ICC）用于测量其评分者内和评分者间的可靠性。计算皮尔逊相关系数以评估其有效性，并将其与帕金森病问卷（PDQ - 39）、意大利语版老年抑郁量表（GDS）、医院焦虑抑郁量表（HADS）以及简明健康调查36项问卷（SF - 36）进行比较。94例PD患者接受了BI评估。所测量的心理测量学特性显著：克朗巴哈系数为0.866，评分者内和评分者间可靠性的ICC分别为0.998和0.993。皮尔逊相关系数显示与PDQ - 39、GDS、HADS和SF - 36具有良好相关性（p < 0.01）。BI是测量PD患者群体残疾情况的有效且可靠的工具。
