The 7-item Generalized Anxiety Disorder Scale (GAD-7) is a reliable and valid measure of anxiety in patients with multiple sclerosis (MS), according to an analysis of the psychometric properties of the scale.
Researchers administered the GAD-7 to 513 patients, and randomly split the sample to conduct an exploratory and confirmatory factor analysis and found:
• The scale showed an acceptable internal consistency and was highly correlated with the Hospital Anxiety and Depression Scale–Anxiety.
• GAD-7 scores were higher in women and patients with secondary progressive MS.
• Higher GAD-7 scores were associated with more depressive symptoms.
