Information on patient satisfaction with orthosis (PSwO) is crucial for verifying and enhancing orthotic quality, for clinical decision making, and for improving patient's quality of life.
To perform the translation and cross-cultural adaptation into Italian of the recently revised version of the Client Satisfaction with Device (CSD) module of the Orthotics and Prosthetics Users' Survey, and then analyze its psychometric properties using factor and Rasch analyses.
We translated and cross-culturally adapted the revised CSD into Italian (CDS-It) and assessed it in a convenience sample of orthotic-user patients with orthopedic, neurological and rheumatic conditions (N = 178; 56% men; median age, 62 years). Exploratory factor analysis and Rasch analysis (rating scale model) were used to investigate, respectively, dimensionality and metric properties of the scale.
Factor analysis confirmed the substantial unidimensionality of the CSD-It. The rating scale fulfilled the category functioning criteria. All items fitted the Rasch model except #2 ("The weight of my device is manageable") that overfitted the model, and #4 ("It is easy to put on my device") that was underfitting in six stroke patients (i.e. not systematically). The targeting of item difficulty to person ability was out of range. The person separation reliability was 0.70 and Cronbach's alpha 0.73. The residual correlation between items #7 and #8 showed a borderline local dependency.
This study confirms the validity of the CSD-It, and provides a useful starting point for further refinement of this outcome measure.
患者对矫形器的满意度信息对于验证和提高矫形器质量、临床决策以及改善患者生活质量至关重要。
对矫形器和假肢使用者调查中最近修订的设备客户满意度（CSD）模块进行翻译并跨文化改编为意大利语版本，然后使用因子分析和拉施分析来分析其心理测量特性。
我们将修订后的CSD翻译并跨文化改编为意大利语版本（CDS-It），并在患有骨科、神经科和风湿性疾病的矫形器使用者患者的便利样本中进行评估（N = 178；56%为男性；中位年龄62岁）。分别使用探索性因子分析和拉施分析（评分量表模型）来研究该量表的维度和度量特性。
因子分析证实了CDS-It具有显著的单维度性。评分量表符合类别功能标准。除了#2（“我的设备重量便于操控”）过度拟合模型以及#4（“我的设备很容易穿戴”）在六名中风患者中拟合不足（即非系统性）外，所有项目均符合拉施模型。项目难度与个人能力的匹配超出范围。个人分离信度为0.70，克朗巴哈系数为0.73。项目#7和#8之间的残差相关性显示出临界局部依赖性。
本研究证实了CDS-It的有效性，并为进一步完善这一结果测量提供了有用的起点。
