DSM-IV anxiety disorders included generalized anxiety disorder, post-traumatic stress disorder, agoraphobia, panic disorder, and social phobia. All participants who met DSM-IV criteria for an anxiety disorders in the 12 months prior to the interview were categorized as “past 12 months”. Those who met DSM-IV criteria for an anxiety disorder during the lifetime, but not in the 12 months prior to the interview, were coded as “lifetime”.
Functional impairment assessed with the World Health Organization-Disability Assessment Schedule Version 2.0 (WHO-DAS II). Scores range from 0–100, with higher scores indicating more severe impairment.
Mean estimates are weighted to be nationally representative of Black adults in the United States, age 50 and older.
Adjusted mean difference in impairment for participants who met DSM-IV criteria for an anxiety disorder during the lifetime, compared to those who never met anxiety disorder criteria. The difference estimates were obtained from linear regression models, run separately for each type of impairment, that control for age and gender, includes survey weights, and accounts for the complex sampling design.
