SF-36量表在深圳市农村老年人中的应用

Applicability of SF-36 in Elderly Living in Rural Area around Shenzhen

目的 :探讨健康调查量表SF -36在农村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 6 6 6名农村老年人 ,用分半信度、内部一致性、效标关联效度、构想效度和结构效度等指标对SF -36量表进行评判。结果 :该量表具有良好的内部一致性 ,8个维度的Cronbach’a系数均≥ 0 8。除心理健康 (MH)外 ,各维度的分半信度较好 ,Pearson相关系数均≥ 0 7。构想效度和效标关联效度令人满意。因子分析产生两个因子 ,能解释总方差的 6 3 14 % ,且除精神影响 (RE)外其它各维度在相应因子有较满意的因子载荷量 (≥ 0 4 )。结论 :SF -36量表基本适用于农村老年人生活质量评价 ,但部分条目需进行调整。

Objective: To study the reliability, validity and feasibility of SF-36 Health Survey Scales in elderly living in rural area around Shenzhen of south China. Method: 666 old people aged 60 or above were assessed with SF-36. Split-half reliability, internal consistency, criterion-related validity, discriminant validity and construct validity of the scale were tested. Result: All Cronbach alpha coefficients were 0.8 or above in eight subscales. The internal consistency was good. The split-half reliability of every subscale was preferable and Person correlation coefficients were 0.7 or higher, except that of Mental Health. Good discriminant validity and criterion related validity were obtained. Factor analysis showed two factors, which could account for 63% of total variance. Every subscale held moderate loading in its relevant facto, except that of Role-Emotion.Conclusion:SF-36 was applicable for life quality assessment in country-dwelling elderly population after some item revisions.
