《老人选择卫生服务能力评估问卷》的信度、效度研究

A Study of Reliability and Validity on Questionnaire of Execute Health Care Provider (QEHCP)

目的 对《老年人选择卫生服务能力评估问卷》的信度、效度进行评估。方法 使用自制的《老人选择卫生服务能力评估问卷》 ,用心理测量学评估问卷的方法量化评估老人是否具有自己选择提供卫生服务的能力 ,由两位评估员间隔 2 4h分别独立评估 ,对问卷进行一致性分析评估其信度 ;用因子分析、与其他评估方法的相关因素分析、与经验评估测评结果分析来评估其效度。结果 该问卷两次复测得分的相关系数为 0 87,单向盲法由两位评测者分别评估得分相关系数为 0 89,内部一致性检验 ,问卷各部位的α系数均大于 0 87,整体α系数为 0 90 ;抽取 4个因子进行效度检验 ,贡献率累计为 6 7 4 6 % ;与MMSE相关系数为 0 76 ,与IADL相关系数为 0 2 8;问卷得分与经验评估相关系数为 0 4 8,诊断符合率为 73 3%。结论 问卷条目具有良好的同质性和鉴别效度 ;问卷结构分布较为合理 ,内部一致性及稳定性较好 ,符合心理测量学的要求 ;测验结果与相关测量工具和经验评估结果具有较好的一致性 ,该问卷可以作为评估老人是否具有选择提供卫生服务机构能力时使用。

Objective By psychometric evaluating questionnaire,evaluate the decision-making capability of the elderly to choose the offer of health service,and evaluate the reliability and validity.Methods Using the self-made Questionnaire of Execute Health Care Provider (QEHCP) and psychometric evaluating questionnaire,evaluate the decision-making capability of the elderly to choose the offer of health service.Two evaluators assessed it independently every 24 h,and evaluate its reliability.Using factor analysis and other evaluating methods to analyze the relative factors and its validity with experiential evaluating results.Results This questionnaire was tested twice.The relative coefficient of the scores was over 0.87,αcoefficient was 0.90.Four factors were taken to examine validity;the whole contribution rate was 67.46%.The relative c0efficient of MMSE and IADL was 0.76,0.28 respectively.The coefficient of the questionnaire score and experiential evaluation was 0.48,diagnosis standard rate was 73.3%.Conclusion The questionnaire′s items have good qualities in general,homogeneity and discrimination validity are also pretty good.The distribution of the questionnaire is reasonable.The internal consistency and stability was good,and satisfied the psychometric requirements.There also were good consistency between the results of the questionnaire and the result of MMSE,IADL and experience appraisal.This questionnaire can be used to evaluate if the elder have the ability to choose health service organization.
