This study evaluated the validation of STAI Trait-Anxiety Scale in suicide cases and community living controls in rural China. The participants were 392 suicides and 416 controls. Cronbach's Alpha was computed to evaluate the internal consistency. The Spearman Correlation Coefficient between Trait-Anxiety Scale and other instrument was calculated to evaluate the external validity, and the Exploratory Factor Analysis was used to evaluate the construct validity. The results showed the Cronbach's Alpha was .891 and .787 respectively in case and control groups. Most of the correlations between instruments were significant. We found 2 factors in cases and 3 factors in controls. We could cautiously infer that the Trait Anxiety Scale was an adequate tool to measure trait anxiety through proxy data in suicide victims and living controls in rural China.
