Objective: To investigate the association between personality disorders and nonfatal unintentional injuries in a representative sample of US adults.

Methods: Data on self-reported nonfatal unintentional injuries during the 12 months before the interview were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were analyzed; 43 093 adults 18 years participated in the NESARC wave I survey in 2001–02. Personality disorders were determined using the NIAAA Alcohol Use Disorders and Associated Disabilities Interview Schedule-DSM-IV.

Results: Individuals with at least one personality disorder had a significantly higher 12-month incidence of injuries than people without any personality disorder (p<0.001). After accounting for sociodemographic characteristics or other mental disorders, OR was 1.54 (95% CI 1.39 to 1.71) for individuals with one personality disorder and 1.80 (95% CI 1.58 to 2.05) for individuals with two or more personality disorders compared with people with no personality disorder.

Conclusion: Personality disorders were associated with a significantly increased risk of unintentional injuries. This information has important implications for the treatment of patients with these disorders.
