Their sample was 914 nondemented people aged 70 or older. Subjects were evaluated for social anxiety according to DSM-IV criteria. Out of the 914 subjects, 1.9 percent were determined to have social anxiety, and an additional 1.6 percent fulfilled criteria A, C, and D, but not B, for the condition. (Criterion A is marked, persistent fear of social situations; criterion B is that exposure to a feared social situation almost always provokes anxiety; criterion C is that the person recognizes that the fear is excessive, and criterion D is that feared social situations are avoided or endured with intense anxiety.) Thus 3.5 percent of the sample had social anxiety that caused social consequences.
