老年原发性高血压患者生活质量量表编制的商榷

The development of the quality of life questionnaire for elderly hypertensive patients

目的 编制和检验适合国情、符合老年原发性高血压特点的生活质量评定工具。 方法 形成条目库并进行条目分析和因子分析以选取合适条目构成多维度量表 ,然后选择 96例老年轻、中度高血压患者 ,对量表进行信度和效度检验。 结果 经筛选和测试形成包括躯体健康、心理健康和社会功能 3个分量表共 2 2项条目的自评量表。各分量表的Cronbachα系数 0 787～ 0 819,重测信度 0 749～ 0 82 1,校正后折半信度 0 6 76～ 0 773;因子分析显示因子数与量表的理论结构一致 ;各分量表与SF 36健康调查表对应部分存在中度相关 ,中度或新近诊断高血压患者量表得分与轻度或非新近诊断高血压患者存在统计学差异。 结论 本量表通过信度和效度检验 。

Objective To develop and validate a means suitable for measuring the quality of life in Chinese elderly hypertensive patients. Methods A pool of items were selected from literature review,interviews with patients and physicians.Then the preliminary questionnaire was administered to 96 elderly hypertensive patients.Items reduction was done by item analysis and factor analysis,which was also performed to identify domains.These domains were assessed for reliability and validity. Results The 22 item self administered questionnaire called EH 22 was developed.The questionnaire comprised 3 domains:physical health,mental health and social function.Domain scores were reproducible after 2 weeks ( r =0 749～0 821)and were internally reliable (Cronbach α=0 787～0 819).In an exploratory principal axes factor analysis,76 8% of the common variance was explained by 3 factors that correlated with the initial domains.Construct validity was demonstrated by moderate correlation with SF 36 related component scores( r =0 38～0 68).Patients with moderate or newly diagnosed hypertension responded with high(worse)scores than those with mild or non newly diagnosed hypertension. Conclusions EH 22 is valuable in the measurement of quality of life in the elderly hypertensive patients.
