建立社会健康测量框架，在不同人群中测试项目，建立项目反应理论(IRT)题库。文献综述指导社会功能和社会关系子域的框架开发。根据患者的反馈对条目进行修订，并对社会功能条目进行现场测试。分析包括探索性因素分析(EFA)、验证性因素分析(CFA)、双参数IRT建模和差异项目功能评价(DIF)。分析样本包括956名一般人群受访者，他们回答了56个参与能力和56个参与项目满意度。全民教育和CFA确定了三个参与分领域的能力。然而，由于正负措辞和内容冗余，许多试题不符合IRT模型，因此题库还不存在。EFA、CFA和IRT确定了两个初步满意度题库。在广泛的项目准备和审查之后，EFA、CFA和IRT指导的题库帮助提供了更高的测量精度和灵活性。有两种满意的简短表格可用于研究和临床实践。这项初步的验证研究产生了修订后的项目库，目前正在新的临床样本和人群中进行测试。
To develop a social health measurement framework, to test items in diverse populations and to develop item response theory (IRT) item banks.A literature review guided framework development of Social Function and Social Relationships sub-domains. Items were revised based on patient feedback, and Social Function items were field-tested. Analyses included exploratory factor analysis (EFA), confirmatory factor analysis (CFA), two-parameter IRT modeling and evaluation of differential item functioning (DIF).The analytic sample included 956 general population respondents who answered 56 Ability to Participate and 56 Satisfaction with Participation items. EFA and CFA identified three Ability to Participate sub-domains. However, because of positive and negative wording, and content redundancy, many items did not fit the IRT model, so item banks do not yet exist. EFA, CFA and IRT identified two preliminary Satisfaction item banks. One item exhibited trivial age DIF.After extensive item preparation and review, EFA-, CFA- and IRT-guided item banks help provide increased measurement precision and flexibility. Two Satisfaction short forms are available for use in research and clinical practice. This initial validation study resulted in revised item pools that are currently undergoing testing in new clinical samples and populations.
