To test the reliability and validity of the "Defeat Scale" and explore whether the scale is suitable for use in surveys of college athletes. A total of 226 athletes from five universities in China were selected for evaluation using the defeat scale. Factor analysis and correlation analysis were used to explore the reliability and validity of the defeat scale. Exploratory factor analysis showed that two factors could be extracted from this scale, namely a sense of decadence and a sense of low achievement. Confirmatory factor analysis showed that the model fit of the two factors was excellent (X/DF = 2.809, RMSEA = 0.092, SRMR = 0.054, NFI = 0.891, IFI = 0.927, CFI = 0.926, GFI = 0.919, TLI = 0.910) . The convergent validity AVE values are 0.579 and 0.505 respectively, AVE > 0.5, and the combined reliability is 0.946 and 0.746 respectively. Both > 0.7 indicate good convergence effect. The arithmetic square roots of AVE, 0.760 and 0.710, are both higher than the absolute value of the correlation coefficient between the two dimensions, 0.30, indicating good discriminant validity; and the Cronbach's alpha coefficient of defeat is 0.931, and the Spearman-Brown coefficient is 0.888. The defeat scale has good reliability and validity among college athletes.
为检验“挫败感量表”的信效度，并探讨该量表是否适用于大学生运动员的调查。选取了中国五所大学的226名运动员使用挫败感量表进行测评。采用因素分析和相关分析来探讨挫败感量表的信效度。探索性因素分析表明，该量表可提取出两个因素，即颓废感和低成就感。验证性因素分析表明，这两个因素的模型拟合良好（X/DF = 2.809，RMSEA = 0.092，SRMR = 0.054，NFI = 0.891，IFI = 0.927，CFI = 0.926，GFI = 0.919，TLI = 0.910）。收敛效度AVE值分别为0.579和0.505，AVE > 0.5，组合信度分别为0.946和0.746，均> 0.7，表明收敛效果良好。AVE的算术平方根0.760和0.710均高于两个维度间相关系数的绝对值0.30，表明判别效度良好；且挫败感量表的Cronbach's alpha系数为0.931，Spearman-Brown系数为0.888。挫败感量表在大学生运动员中具有良好的信效度。
