神经源性膀胱患者自我管理量表的编制及信效度检验

目的 编制神经源性膀胱患者自我管理量表,并进行信效度检验,为评价神经源性膀胱患者自我管理提供有效工具。方法 在文献分析及半结构式访谈的基础上,通过德尔菲法专家评审和预调查形成预试量表,选取128例神经源性膀胱患者对预试量表进行项目分析,选取396例神经源性膀胱患者对量表进行信效度检验,形成正式量表。结果 正式量表包括3个维度29个条目。总量表Cronbach α系数为0.725,2周后的重测信度为0.790。总量表的内容效度指数为0.900,探索性因子分析提取出7个公因子,3个维度的累计方差贡献率分别为62.004%、62.366%、67.142%,验证性因子分析显示模型拟合良好。结论 神经源性膀胱患者自我管理量表信效度良好,可作为神经源性膀胱患者评价自我管理水平的工具。

Development and Validation of Self-management Scale for Neurogenic Bladder Patients

Objective To develop a self-management scale for neurogenic bladder patients, to test its reliability and validity and to provide effective method to self-management of neurogenic bladder patients. Methods After literature review and semi-structured interview, the initial self-management scale for neurogenic bladder patients was formed with Delphi expert consultation and pilot investigation. Total of 128 patients with neurogenic bladder were selected to perform the item analysis for the provisional scale. 396 patients with neurogenic bladder were surveyed to test the reliability and validity of the final scale. Results The final scale consisited of 3 dimensions and 29 items. The Cronbach’s α coefficient and content validity index（S-CVI）of the total score was 0.725 and 0.900 respectively and 2-week test-retest reliability was 0.790. Seven common factors were extracted from the exploratory factor analysis, and the cumulative variance contribution rate of the three dimensions was 62.004%,62.366% and 67.142% respectively. Confirmatory factor analysis revealed good fit of the model. Conclusion The developed scale has good reliability and validity and can be used as an assessment tool for self-management ability of neurogenic bladder patients.
