BackgroundDespite the strong associations between personality disorders and problem/pathological gambling, few studies have investigated the relationships between personality disorders, problem-gambling severity and suicidal thoughts/behaviors.ObjectivesWe examined the relationships between problem-gambling severity and personality disorders among individuals with differing levels of suicidality (none, thoughts alone, attempts).MethodsWe analyzed data from 13,543 participants of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) study. First, differences in sociodemographic characteristics and prevalence of personality disorders were analyzed according to problem-gambling severity and suicidality status. Second, we performed a logistic regression to assess among the relationship between problem-gambling severity and DSM-IV Axis II psychopathology according to suicidality level.ResultsAt-risk or problem/pathological gambling groups showed higher rates of a wide range of personality disorders compared to non-gamblers. Logistic regression showed that at-risk pathological gamblers had a higher odds ratio for any personality disorder in the group with no history of suicidality, particularly for cluster-B personality disorders. Odds ratio interaction analysis identified the relationship between problem-gambling severity and personality disorders, particularly those in cluster B, differ according to suicidality status.ConclusionsOur findings suggest a complex relationship between suicidality, problem-gambling severity and personality disorders. The stronger relationship between problem-gambling severity and personality disorders in people with no suicidality as compared to some suicidality suggests that some of the relationship between greater problem-gambling severity and Axis II psychopathology is accounted for by increased suicidality. The findings have implications for clinical interventions targeting suicidality in individuals with gambling disorders.
