Abstract
Purpose
To test the reliability and validity of the "Defeat Scale" and explore whether the scale is suitable for use in surveys of college athletes.
Methods
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.
Results
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 (X2/DF = 2.809, RMSEA = 0.092, SRMR = 0.054, NFI = 0.891, IFI = 0.927, CFI = 0.926, 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.
Conclusion
The defeat scale has good reliability and validity among college athletes.
