目的:对"生长壮老取决于肾"流行病学调查信息采集表(成人用表)的预调查进行信度和效度评价。方法:2010年立冬日开始到大寒日结束,在辽宁、上海、天津3个地区多中心,以10-70岁之间获得知情同意的体检健康人群为调查对象,实施"生长壮老取决于肾"流行病学调查信息采集表调查,其中有效样本165例。结果:165例有效样本的年龄为(34.92±16.99)岁,其中男性65例(39.4%),年龄(33.91±16.94)岁;女性100例(60.6%),年龄(35.57±17.08)岁。内部一致性信度评价:男性量表总Cronbach’sα系数是0.825,女性量表总Cronbach’sα系数是0.711,说明本量表的内部一致性良好。分半信度:本研究男性量表的分半信度为0.605,女性量表的分半信度为0.524,结果较好。校标效度:本研究女性量表与SF-36健康状况调查问卷在总分上具有一定相关性Spearman’s r=0.44,P〈0.05,头发、耳目、骨牙、四肢肌肉、女性生殖系统、智力及其他症状与SF-36量表生理维度具有相关性,男性二阴二便情况、女性生殖情况、智力、其他症状与SF-36量表的心理维度具有相关性。区分效度:年龄〉40岁的男性20例,年龄≤40岁的男性45例,两组人群分别在头发、耳目、骨牙、皮肤、二阴二便、生殖方面有较好的区分效度。年龄〉35的女性45例,年龄≤35的女性55例,此两组人群分别在头发、耳目、骨牙、皮肤、智力方面有较好的区分效度。结论:"生长壮老取决于肾"流行病学调查信息采集表具有较好的可行性、信度和效度,能够较好的反映出健康人群随着生长壮老不同阶段而有着相应的外在指征变化。
Objective: To evaluate the reliability and validity of questionnaires for epidemiology investigation on 'human's development relies on kidney'. Methods: From lunar beginning of Winter to Greater Cold in 2010, healthy people from 10 to 70 years old in Liaoning province, Shanghai and Tianjin, who finished questionnaires for epidemiology investigation on 'human's development relies on kidney' were selected as the objects, under the condition of obtaining agreement individually. Among them 165 samples were effective. Results: The average age of the samples was (34.92+16.99) years. 65 cases (39.4%) were male, with an average age of (33.91~16.94) years, and 100 cases (60.6%) were female, with an average age of (35.57+_17.08) years old. Cronbach's alpha coefficient of the male was 0.825, and that of the female was 0.711, indicating that the Internal consistency of scale was good. Split-half reliability of the male was 0.605, and that of the female was 0.524. Data of Split-half reliability showed good results. Criterion validity data showed a correlation between women research scale and SF-36 health questionnaire (Spearman's r=0.44, P〈0.05). The correlation showed in hair, eyes and ears, teeth, limb bone muscle, the female reproductive system, intelligence and other symptoms between women research scale and physiological dimension of SF-36 scale, and the correlation showed in male two lower orifices, female reproductive system, intelligence and other symptoms between research scale and psychological dimension of SF-36 scale. Discrimination validity data showed that: (1) between the male over 40 years old (20 cases) and those younger than 40 years old (including 40, 45 cases), there was a good discrimination validity in hair, ears, eyes, teeth, skin and bone, two lower orifices, reproductive system. (2)between the female over 35 years old (45 cases) and those younger than 35 years old (including 35, 55 cases), there was a good discrimination val
