Previous studies indicated that poor quantity and quality of instrumental support are one of the main barriers in the application of transitional care. Instrumental support, as one common function of social support, is the provision of financial assistance, material goods, or services. The purpose of our study is to develop an Instrumental Support in Transitional Care Questionnaire (ISTCQ) and use this questionnaire to make an assessment among older adults with chronic diseases.
The draft questionnaire was examined by 18 experts from different professional fields performing three rounds of content validity testing with the Delphi method. Afterward, we conducted a pilot test recruiting 174 participants as a convenience sample in Nantong, China. The construct validity was confirmed via exploratory factor analysis and reliability was assessed using Cronbach's alpha.
The authority coefficient of experts was 0.74-0.99 and Kendall harmony coefficient W was 0.381. The exploratory factor analysis indicated that the questionnaire can be interpreted by three factors: namely, anticipated support (items 1, 2, 3, 4), received support (items 5, 6, 7, 8) and support satisfaction (items 9, 10, 11, 12). These three factors (eigenvalues > 1 and factor loading > 0.4) explained 69.128% of the total variance. Furthermore, the calculation of Cronbach's alpha and test-retest reliability have shown good reliability among each dimension of the 12-item questionnaire (Cronbach's alpha 0.711-0.827, test-retest reliability 0.704-0.818).
Results from the pilot test demonstrated excellent reliability and validity of ISTCQ through each dimension and as an entire.
先前的研究表明，仪器支持的数量和质量差是过渡性护理应用的主要障碍之一。仪器支持作为社会支持的一个常见功能，是提供财政援助、物质商品或服务。我们研究的目的是开发一个过渡性护理仪器支持问卷（ISTCQ），并使用该问卷对慢性病老年患者进行评估。
通过德尔菲法，由来自不同专业领域的 18 名专家对问卷草案进行了三轮内容有效性测试。之后，我们采用便利抽样法招募了 174 名参与者进行了预试验。通过探索性因子分析确认了结构效度，采用克朗巴赫 α 系数评估了信度。
专家的权威系数为 0.74-0.99，肯德尔和谐系数 W 为 0.381。探索性因子分析表明，该问卷可以用三个因素来解释：预期支持（项目 1、2、3、4）、已获得支持（项目 5、6、7、8）和支持满意度（项目 9、10、11、12）。这三个因素（特征值>1，因子负荷>0.4）解释了总方差的 69.128%。此外，各 12 项问卷维度的克朗巴赫 α 系数和重测信度的计算结果均显示出良好的信度（克朗巴赫 α 0.711-0.827，重测信度 0.704-0.818）。
预试验结果表明，ISTCQ 在各个维度和整体上均具有良好的信度和效度。
