This review covers commonly used measures of anxiety. For this review, the author included measures that were 1) measures of general measures of anxiety and severity of anxiety symptoms, 2) administered by self-report, 3) used in rheumatologic populations, and 4) has evidence of adequate psychometric data. To maintain brevity, the majority of the measures reviewed here were selected to provide broad coverage of general symptoms of anxiety, and measures were excluded if they are intended to identify or characterize a specific Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) anxiety disorder (1). Specifically, this author excluded measures typically used to evaluate diagnostic criteria or features of specific anxiety disorders, such as panic disorder, obsessive-compulsive disorder, posttraumatic stress disorder, and others. In addition, broader measures of psychiatric distress, including the Symptom Checklist-90, the General Health Questionnaire, and the Medical Outcomes Study Short Form 36 are not included in this review since they are included elsewhere in this special issue. However, subscales that have been used frequently in rheumatology as “stand-alone” measures, such as the anxiety scale of the Hospital Anxiety and Depression Scale, are included in this review. Importantly, the measures included in this review should not be interpreted as diagnostically significant for an anxiety disorder, even generalized anxiety disorder, but should be used to measure the presence of symptoms and to calibrate the severity of general symptoms of anxiety commonly occurring in rheumatic disease. The measures reviewed below include the State Trait Anxiety Index, the Beck Anxiety Inventory, and the anxiety subscale of the Hospital Anxiety and Depression Scale. In this review, the content and structure of each measure is presented (number of items, recall period, response options, presence of translations, and adaptations), the use in rheumatic disease when possible is discussed, and the psychometric properties of each measure, particularly when validated in any of the rheumatic diseases, is detailed. In addition, information regarding responsiveness of each measure to longitudinal change is presented, including responsiveness to change in rheumatology when available. Finally, a summary of the strengths and weaknesses specific to rheumatology is presented.
