AMS量表在上海市社区人群中的适用性研究

Feasibility of the Aging Males' Symptoms scale for the male population of Shanghai

目的:评价在上海社区人群中应用AMS量表(the aging males'symptoms scale)的信度和效度。方法:以上海市某社区40岁及以上的973例中老年男性为研究对象,采用AMS量表进行调查,计算分半信度系数、Cronbach'sα系数考察量表内在一致性;通过验证性因子分析考察结构效度,t检验、方差分析和相关分析考察区分效度、校标效度和内容效度。结果:AMS量表及各领域的分半信度系数均大于0.78(P<0.01),Cronbach'sα均大于0.82(P<0.01);验证性因子分析结果表明AMS量表可分为3个领域,各条目与其所属领域的相关系数均大于0.49(P<0.01);血清总睾酮水平为校标时的Pearson相关系数为-0.04(P>0.05)。除心理领域得分在不同年龄组间差别无统计学意义外,不同年龄组、有无慢性病组间AMS量表及各领域得分均存在统计学差异。结论:AMS量表应用于上海社区人群时具有较好的信度和效度,是一份较好的老年男性症状评分量表。但其作为迟发性性腺功能减退症(LOH)的筛选工具仍需深入评估。

Objective： To assess the reliability and validity of the Aging Males＇ Symptoms （AMS） scale in the male population of Shanghai. Methods ： We enrolled 973 males aged 40 years and over in a community of Shanghai, China. Using the AMS scale, we calculated the split-half reliability coefficient and Cronbach~ ct coefficient, assessed the validity through confirmatory factor analysis and correlation analysis, and obtained the domain scores of different people by analysis of variance and independent sample test. Results ： The split-half reliability was 〉 0.78 （ P 〈 0.01 ） and Cronbach＇s α coefficients of all the dimensions 〉 0.82 （ P 〈 0.01 ）. Confirmatory factor analysis showed 3 domains in the AMS scale, Pearson correlation coefficients of all the items to their domains were 〉 0.49 （P 〈 0.01 ）, and the total testosterone level was not correlated with AMS scores, with Pearson correlation coefficient of - 0.04 （ P 〉 0.05 ）. Statistically significant differences were found in AMS scores among different age groups as well as among those with different chronic disease histories, but not in the psychological domain among different age groups. Conclusion： The reliability and validity of the AMS scale are acceptable in assessing aging males＇symptoms among the male population of Shanghai, but further studies are needed to determine whether it could be used as a tool for screening late-onset hypogonadism （LOH） in males.
