Mutual comorbidity of different anxiety disorders

The National Comorbidity Survey – Replication data were used to estimate 12-month prevalence, severity, and comorbidity of DSM-IV anxiety, mood, impulse control, and substance disorders.¹ The survey was an in-person structured diagnostic interview of 9,282 people, conducted between 2001–2003 across the USA.¹ The correlation analysis shown on the slide found almost all correlations between mental disorders were positive, and many were statistically significant.¹
