Specificity of trait anxiety in anxiety and depression: Meta-analysis of the State-Trait Anxiety Inventory.

ABSTRACT: The State-Trait Anxiety Inventory - Trait version (STAI-T) was developed to measure an individual's tendency to experience anxiety, but it may lack discriminant evidence of validity based on strong observed relationships with measures of depression. The present series of meta-analyses compares STAI-T scores among individuals with depressive disorders, anxiety disorders, and nonclinical comparison groups, as well as correlations with measures of anxiety and depressive symptom severity, in order to further examine discriminant and convergent validity. A total of 388 published studies (N = 31,021) were included in the analyses. Individuals with an anxiety disorder and those with a depressive disorder displayed significantly elevated scores on the STAI-T compared to nonclinical comparison grou
