摘　　要：目的:构建健康人生理性衰老评价量表。方法:采用文献搜集、专家征询座谈筛选衰老生理性条目,经两轮德尔菲法咨询,对生理性衰老指标体系重要性、可行性、权威程度进行打分,经层次分析法对生理性衰老维度和条目进行权重分配。结果:经生理学等不同专业的17位专家德尔菲法咨询,专家权威程度(Cr)为0.86±0.03;两轮专家协调系数分别为0.264(χ2=229.691,P<0.001),0.293(χ2=228.474,P<0.001),一致性好。健康人生理性衰老量表包括3个维度,即形态体貌、感觉运动、功能状态,每个维度8个条目共24条,3个维度的权重系数分别为0.54,0.16,0.30。量表的Cronbach'sα系数为0.893,重测信度为0.796,公因子的方差累计贡献率为58.17%。结论:通过改良德尔菲法构建的生理性衰老量表较为理想,可为衰老的评定提供参考。Objective：To build a physiological aging scale for healthy people.Methods：We collected age-related physiologic items through literature screening and expert interview.Two rounds of Delphi were implemented.The importance,feasibility and the degree of authority for the physiological index system were graded.Using analytic hierarchy process,we determined the weight of dimensions and items.Results：Using Delphy mothod,17 physiological and other professional experts offered the results as follow：coefficient of expert authorities Cr was 0.86±0.03,coordination coefficients for the first and second round were 0.264（χ^2=229.691,P〈0.001） and0.293（χ^2=228.474,P〈0.001）,respectively.The consistency was good.The aging scale for healthy people included 3 dimensions,namely physical form,feeling movement and functional status.Each dimension had 8 items.The weight coefficients for the 3dimensions were 0.54,0.16,and 0.30,respectively.The Cronbach＇s a coefficient of the scale was 0.893,the reliability was 0.796,and the variance of the common factor was58.17%.Conclusion：The improved Delphi method or physiological aging scale is satisfied,which can provide reference for the evaluation of aging.
