The Interaction Anxiousness Scale: Construct and Criterion-Related Validity

This article presents data regarding the validity and reliability of the Interaction Anxiousness Scale (IAS; Leary 1983c), a self-report measure of dispositional social anxiety. The IAS demonstrates high test-retest and internal reliability. Correlations with measures relevant to social and general anxiety document its convergent and discriminant validity, and it correlates well with measures of anxiety and interpersonal concern in actual interactions.
