Prevalence of Anxiety & Mood Disorders
US National Comorbidity Survey Replication (NCS-R)
The graph below shows the percentage of individuals who have a history of different diagnosable mental health conditions (lifetime prevalence of DSM-IV disorders), using data from a large US study involving nearly 10,000 participants. You can see that the total percentage of individuals who have at some point met diagnostic criteria for some mental health disorder is extremely high, 57.4%, making these problems almost the norm. The most common individual anxiety or mood disorder is clinical depression (major depressive disorder). The most common anxiety disorders are specific phobias and social phobia.
