目的:主要讨论围绝经期综合征(PPS)中医症状学量表的测量误差大小。方法:对2次症状积分值做相关性分析及计算重复测量误差。结果:中医症状加权积分法辨证出的156例PPS患者的证型(参比组)与医生独立经验辨证(待评组)比较,发现二者仅共同检验出55例(35.26%)具有相同的证型;47例PPS患者前后2次症状积分的相关系数为0.98(P〈0.0001),前后2次症状积分的差值经£检验,差异无统计学意义(t=0.20,P=0.85)。测量误差(0.44)及变异系数(1.32%)均较小。结论:PPs中医症状学量表经评价其重测信度较高。
Objective :This paper mainly discussed what the value of measurement error of the TCM symptom scale of perim- enopausal period syndrome (PPS) was. Methods : We analyzed the relative of cumulating score of symptom and calculated the measurement error size between two measurements. Results :There were 55 patients who got the same diagnosis by the TCM symptom weighted score method and the doctors' experience in the 156 patients. There were 47 patients measured twice,and the relative coefficient was 0. 98 (P 〈 0. 0001 ). After hypothesis tested, there was no difference ( t = 0. 20, P = 0. 85 ) in these 47 cases. Both the value of measurement error(0.44) and variance coefficient ( 1.32% ) is low. Conclusion : After evaluated, the test-retest reliability of the TCM symptom scale of PPS is high.
