Approximately how many individuals ages 15-44 experience a diagnosable mental disorder in any given year?

• A. 1 in 4
• B. 1 in 10
• C. 1 in 2
• D. 1 in 20

Answer: (A)

Mental disorders are surprisingly common in early to mid-adulthood. In any given year, about one in four people aged 15–44 meet criteria for at least one diagnosable mental disorder. This figure comes from large surveys that use standardized diagnostic interviews and DSM/ICD criteria, capturing mood, anxiety, substance use, and related conditions. Many disorders begin in adolescence or early adulthood, and comorbidity is common, so some individuals may meet criteria for more than one disorder, yet the overall prevalence remains around 25%. The other options would underestimate or overstate yearly prevalence: half suggests a much higher burden, while 10% or 5% would not align with the typically observed annual reach of diagnosable mental health conditions.
