Anxiety disorders are common among patients with schizophrenia, but they are not always recognized. Social anxiety disorder is often overlooked because it is confused with the negative symptoms of schizophrenia, e.g., anhedonia. Improvement in schizophrenia may reveal a concurrent anxiety disorder, as demonstrated by Pallanti et al. (p. 53). Of 80 treated patients with remitted or partially remitted schizophrenia, 36% had social anxiety disorder. These patients had lower ratings of social adjustment and quality of life than patients without social anxiety. They also had made more, and more lethal, suicide attempts and had a higher rate of past alcohol or substance use disorders. The Liebowitz scale for social anxiety appeared adequate and reliable for assessing social anxiety disorder in schizophrenia. For patients who develop social anxiety disorder after the onset of schizophrenia, medication may be a relevant factor.
