脑卒中患者适时需求调查表的编制及信效度研究

Study on Reliability and Validity of Timing-It-Right Questionnaire for Patients with Stroke

目的:以适时模式为框架,在分析患者需求的变化基础上,编制适时需求调查表。方法:依据相关文献、质性访谈结果、适时模式框架形成条目池。通过两轮专家内容效度评定,并邀请10例脑卒中患者阅读量表,增加和修订条目形成量表初始版本。通过随机抽样法调查新收入院患者200例,进行临床施测回收有效问卷183份,经项目分析和信效度检验形成量表的临床版本。结果:经质性访谈和文献查询,结合适时模式框架,形成73个备选条目池。经预实验及两轮专家内容效度评定,形成36个条目的初始版本。经条目筛选、探索性因子分析,未减少条目。信度分析结果显示:量表总体的Cronbach’sα系数为0.795,各维度数值均在0.7以上;折半信度采用Guttman Spilt-Half系数,量表总折半信度为0.782,各维度数值均在0.7以上;信效度达到心理测量学标准,形成临床应用版本。结论:编制的脑卒中患者适时需求调查表信效度良好。

Objective:Within a timing-it-right framework and based on the analysis of the changes in patient needs, a timeliness requirement questionnaire was compiled. Methods: The article pool was formed according to the relevant literature, qualitative interview results, and timeliness framework. Through two rounds of expert content validity evaluation and the invitation of 10 stroke patients to read over the scale, the articles were expanded and revised to form the initial version of the rating scale. A total of 200 new hospital patients were investigated by random sampling, and 183 effective questionnaires were used for clinical survey and recovery.Through project analysis and reliability and validity tests, the clinical version of the scale was formed. Results:Through qualitative interviews and literature enquiries, combined with the timeliness framework, 73 alternative pools were formed. The initial version of 36 articles was formed by pretests and two rounds of expert content validity evaluation. Item selection and exploratory factor analysis did not reduce the number of articles. The results of reliability analysis showed that the total Cronbach’s α of the scale was 0.795, and the value of each dimension was above 0.7. The half reliability was evaluated by Guttman Split-Half coefficient; the total half reliability of the scale was 0.782, and the value of each dimension was above 0.7. The reliability and validity met the psychometric standards, and the clinical application version of the rating scale was established. Conclusion:The stroke patient timeliness requirement questionnaire has good reliability and validity.
