The National Comorbidity Survey is a large-scale mental health study conducted in the United States that utilizes structured interviews to estimate the prevalence of psychological disorders. Data collected from nearly $10,000$ adults between $2002$ and $2003$ revealed varying lifetime prevalence rates for different conditions, including major depressive disorder ($16.9\%$), alcohol abuse ($13.2\%$), drug abuse ($8.0\%$), generalized anxiety disorder ($5.7\%$), bipolar disorder ($4.4\%$), and obsessive-compulsive disorder ($2.3\%$). These comprehensive statistics provide crucial insights that help identify statistical relationships among disorders and other contributing factors, serving the needs of basic researchers, clinicians, and policymakers.
