Introduction: In the previous study, social anxiety is reported as a comorbid symptom among people with schizophrenia and should be highlighted in achieving recovery. We aimed to clarify the risk factors of social anxiety symptoms in young adults with schizophrenia focusing on the social cognition, social functioning, and duration of untreated psychosis (DUP). Methods: Two hundred seven outpatients with schizophrenia aged 40 years or younger (101 men, 106 women) were recruited at the Toho University Omori Medical Center. They were assessed for the severity of social anxiety symptoms, the level of psychotic symptoms, depression or anxiety symptoms, social functioning, cognitive function including facial emotional cognition, theory of mind, insight for illness, subjective quality of life, and subjective well-being. We conducted multiple linear regressions using social anxiety symptom score as an outcome variable and patient background factors as predictors. Results: Of the 207 patients with schizophrenia, N=30 (14.5%) met the criteria of social anxiety disorder according to the Mini-International Neuropsychiatric Interview. Social anxiety symptom score was correlated with the level of psychotic symptoms, depression, anxiety, subjective quality of life, subjective well-being, and social functioning. Multiple regression showed that social anxiety symptom score was significantly associated with social functioning, female sex, age at onset and DUP. Conclusion: Social anxiety comorbid with schizophrenia was associated with subjective difficulty and predicted by delay in the first treatment. Adequate intervention focusing on social anxiety from the early phase of illness may be helpful for achievement of treatment goals.
