摘要
目的 探讨老年人生活质量调查表在老年人群中应用的信度、效度和可行性。 方法 以问卷访谈的形式调查 10 5 5名老年人 ,用分半信度、内部一致性、判别效度和结构效度等指标对调查表进行评判。 结果 该调查表具有良好的内部一致性 ,11项健康相关内容的 Cronbach'a系数均≥ 0 .7。调查表的分半信度较好 ,用三种方法获得的 Pearson相关系数均≥ 0 .5。判别效度和结构效度令人满意。因子分析产生 4个因子 ,能解释总方差的 5 7.92 % ,且各项目在相应因子上有较满意的因子载荷量 (≥ 0 .4 )。
Objective To evaluate the reliability, validity and feasibility of the Elderly Life Quality Survey Scales in elderly population. Methods 1055 elderly people were interviewed with this survey scales and the survey scales was assessed by split-half reliability, internal consistency, discriminant validity and construct validity. Result All Cronbach alpha coefficients were 0.7 or above in eight subscales and the internal consistency was better. The split-half reliability of every subscale was preferable and Pearson correltaion coeffcients were 0.5 or above. Good discriminant validity and construct validity were obtained. Four factors were resulted from factor analysis, which could account for 57.92% of total variance. Every subscale held moderate loading(≥0 4) in its relevant factor. Conclusion The Elderly Life Quality Survey scales was applicable for life quality assessment in elderly population.
