农村高血压患者居家安全风险评估问卷的编制及信效度检验

Development and validation of risk assessment questionnaire for rural hypertension patients during home care

目的 编制农村高血压患者居家安全风险评估问卷，并检测其信效度。方法 以风险管理理论和“知 - 信 - 行”模式为指导理论，通过与患者接触、个人深度访谈、文献查阅、专家咨询、预测试形成正式施测问卷。 对 245 例农村高血压患者进行正式施测，检验问卷信效度，形成最终版问卷。 结果 经因子分析提取出 4 个因子，共 40 个条目，累计方差贡献率为 69.924% ， 内容效度为 0.866 ， 各因子间的相关系数为 0.256～0.557 ， 各因子与总分之间的相关系数为0.621～0.762 ； Cronbach蒺s α 系数为 0.852 ，折半信度为 0.902 。 结论 问卷具有良好的信效度，可以用于农村高血压患者居家安全风险的评估。

Objective To test the reliability and validity of risk assessment questionnaire for rural hypertension patients during home care. Methods The initial questionnaire was formed on the basis of long-term contact with patients ,in-depth interview ,literature review,expert consultation and pilot test. The reliability and validity of the fi- nal questionnaire was tested among 245 patients. Results Four factors were identified including 40 items and the cumulative contribution of variance was 69.924%. The content validity was 0.866. The correlation coefficient among four factors ranged from 0.256 to 0.557 and the correlation coefficient between each factor and total score ranged from 0.621 to 0.762. The Cronbach＇s oL coefficient and split-half coefficient was 0.852 and 0.902,respectively. Conclusion The questionnaire was proved to be reliable and valid. It can be used to assess the risks for rural hy- pertension patients during home care.
