摘要
目的编制一套适合测评我国城市老年人生命质量的量表.方法通过文献查阅法、访谈法、专家咨询法等确定条目池,并进一步形成初始量表.采用变异度法、相关系数法、因子分析法、逐步回归法对初始量表进行条目筛选,由保留的条目组成最终的测试量表.并对该量表进行信度和效度评价.结果初始量表共包括60个条目,经统计学筛选后,保留了34个条目,对其重新分类最终形成一个包含生理、心理、社会三个维度共34+1个条目的测试量表.量表的分半信度系数为0.7977,总量表及生理、心理、社会维度的Chronbach's α系数分别为0.8974,0.8054,0.8057,0.7783.总量表、生理、心理、社会维度两次测定问重测信度系数分别为0.83,0.76,0.86,0.80.通过因子分析,提取12个公因子,解释方差总变异的72.3%.因子负荷在0.3771～0.8268之间.结论该量表具有较好的信度和效度,对城市老年人生命质量的测评具有一定价值.
Objective To develop a life quality scale which is applicable to the urban elderly in China. Methods The item pool was defined by referring to related articles, interviews and consulting experts etc, and thus formed the primary scale. Such methods as variance method, correlation coefficient ,factor analysis and stepwise regression were applied in modifying the primary scale. When the formal scale composed of selected items is finished, it＇s reliability and validity is evaluated. Results 34 items are selected out of the 60 items of the initiative scale after statistic selection. The formal scale, which includes three aspects of physiology, psychology and society, is composed of 34 ＋ 1 items by re-evaluating and re-sorting. Split-half reliability coefficient is 0. 7977, the Chronbach＇ s ct of the general scale, PH, PS and SO is 0. 8974,0. 8054,0. 8057,0.7783 respectively,the test-retest stability coefficient of the general scale, PH, PS and SO is 0.83,0.76, 0.86, 0.80 respectively. By constructive validity analysis, 12 common factors from 34 items were selected which can account for 72 percent of the total variance. Factor loadings are between 0. 3771 -0. 8268. Conclusion The formal scale is good at reliability and validity, and it is valuable for measuring the life quality of the urban elderly.
