title: [Feasibility of the aging males' symptoms scale for the male population of Shanghai].
abstract: 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's alpha 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 alpha 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.
  
  
  CONCLUSIONS
  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.
