What percentage of adults is estimated to experience personality disorders?

The correct estimation for the percentage of adults who experience personality disorders is approximately 9%. This figure is supported by epidemiological studies, which indicate that personality disorders are relatively common mental health issues within the adult population. The prevalence varies slightly based on the specific personality disorder being assessed, but on average, about 9% is a widely accepted estimation.

Understanding this statistic is important in recognizing the significant impact personality disorders can have on individuals and society as a whole. It highlights the necessity for mental health awareness and interventions aimed at supporting affected individuals. The relatively close estimates of other percentages reflect the variability in population studies and diagnostic criteria, but 9% remains the most accurate approximation among the options listed.
