高血压患者生命质量量表研制及评价

Development and validation of the quality of life systematic instruments for chronic diseases-hypertension scale

目的研制慢性病患者生命质量测定量表体系中的高血压量表(QLICD-HY),并对其进行测评。方法采用程序化决策方式,结合我国语言和文化背景进行量表开发和研制,并通过157例高血压患者的测定对量表进行效度、信度、反应度等考核评价。采用统计描述、相关分析、因子分析、配对t检验等方法进行分析。结果高血压患者生命质量测定量表(QLICD-HY),包括慢性病共性模块30个条目和高血压特异模块17个条目。量表各领域及亚领域(facet)的内部一致性信度α值基本在0.6以上、重测相关系数(r值)大多在0.8以上;各条目与所属亚领域及其领域的相关均大于与其他亚领域及领域的相关,相关系数(r值)在0.7以上者占56.52%;量表能够反映出高血压患者治疗前后生命质量的变化。结论高血压患者生命质量测定量表(QLICD-HY)具有较好的信度、效度、反应度和临床可行性,可以作为我国高血压患者生命质量的测评工具。

Objective To develop and validate the quality of life instruments for chronic diseases-hypertention（QLICD-HY）.Methods The programmed decision-making method was used to develop a scale associated with our domestic language and culture.The psychometric properties of the instrument were evaluated by analyzing the data from 157 patients with hypertension.The statistic methods used in this research included statistic descriptions,Pearson correlation,factor analysis,and paired t student test.Results The QLICD-HY was developed with 30 item of general module and 17 items of specific module.Most coefficients of internal consistency are above 0.6 and test-retest reliability coefficients are above 0.8 for facet and domain scores;all of correlation coefficients between item and it＇s facet and domain are higher than the item with other facets and domains,and most of the r values are above 0.7.The scale has the ability to detect clinical change due to treatment.Conclusion The QLICD-HY is valid,reliable,sensitive and reasonable opearation in clinical settings,and it can be used to assess quality of life for patients with hypertension.
