The SAT-16 is a 16-item self-administered questionnaire measuring patient satisfaction with the quality of care during stay in a rehabilitation unit. A comprehensive psychometric analysis of SAT-16 was performed using both classical test theory and Rasch analysis (RA) to examine its validity and metric properties, and provide further insights for its clinical use in rehabilitation settings.
A sample of 9458 patients, consecutively admitted to two Rehabilitation Centres, was examined with SAT-16. Factor (both explorative and confirmatory) analysis and RA were used to process the data in order to examine validity and metric properties of SAT-16. Dimensionality, item fit to the model, response category performance and internal construct validity were assessed.
Two subscales were identified by factor analysis and expert review, respectively related to satisfaction with clinical care (items 1-9), and satisfaction with hospital organization and facilities ("hotel" aspects of care, items 10-16). Each subscale underwent a separate RA. Response categories were revised in both subscales of SAT-16, obtaining a new 3-level rating scale. Both subscales showed high internal consistency and internal validity.
RA confirmed the appropriateness of SAT-16 and its usefulness in identifying areas for quality improvement. Overall, the questionnaire allows to assess patient satisfaction with the services through: 1) two sub-scores respectively specific for satisfaction with "clinical care" and "hotel aspects of care"; 2) additional information gathered in the optional open-ended questions.
SAT-16 是一个 16 项的自我管理问卷，用于测量患者对康复单元住院期间护理质量的满意度。使用经典测试理论和 Rasch 分析（RA）对 SAT-16 进行了全面的心理测量学分析，以检验其有效性和度量特性，并为其在康复环境中的临床应用提供进一步的见解。
对连续入住两个康复中心的 9458 名患者进行了 SAT-16 检查。使用因子（探索性和验证性）分析和 RA 来处理数据，以检验 SAT-16 的有效性和度量特性。评估了维度、项目与模型的拟合、反应类别表现和内部结构有效性。
通过因子分析和专家审查分别确定了两个分量表，分别与对临床护理的满意度（项目 1-9）和对医院组织和设施的满意度（护理的“酒店”方面，项目 10-16）相关。每个分量表都进行了单独的 RA。SAT-16 的两个分量表都进行了修订，增加了新的 3 级评分量表。两个分量表都显示出较高的内部一致性和内部有效性。
RA 证实了 SAT-16 的适当性及其在确定质量改进领域的有用性。总体而言，该问卷通过以下方式评估患者对服务的满意度：1）两个分量表分别针对对“临床护理”和“酒店护理方面”的满意度；2）通过可选的开放式问题收集的附加信息。
