The correct answer is supported by epidemiological studies which indicate that approximately 25-30% of adults in the United States experience a diagnosable psychological disorder in a given year. The figure often cited in reputable sources, such as the National Institute of Mental Health (NIMH), is close to 26%. This statistic encompasses a range of disorders, including anxiety disorders, mood disorders, and substance-related disorders, reflecting the prevalence of mental health issues within the adult population.

Providing this context helps clarify the scope of psychological disorders that may be included in such prevalence reports, and it emphasizes the significant impact mental health challenges have on society as a whole.
