AbstractThe fourth edition of the Generalized Anxiety Disorder Questionnaire (GAD-Q-IV) is a self-report measure that is commonly used to screen for the presence of generalized anxiety disorder (GAD). The current investigation attempted to identify an optimal cut score using samples obtained from an outpatient psychiatric (n=163) and primary care clinic (n=99). Results indicated that a cut score of 7.67 provided an optimal balance of sensitivity (.85) and specificity (.74) comparable to a previously identified cut score (5.7) across both samples (sensitivity=.90, specificity=.66). However, both cut scores were consistently outperformed by a score representing the criteria for GAD described in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (sensitivity=.89, specificity=.82).
