Problem-gambling severity, suicidality and DSM-IV Axis II personality disorders

Area of Science:

• Psychiatry
• Psychology
• Public Health

Background:

• Strong associations exist between personality disorders and problem/pathological gambling.
• Limited research has explored the interplay of personality disorders, gambling severity, and suicidal ideation/behaviors.

Purpose of the Study:

• To investigate the relationships between problem gambling severity and personality disorders across different levels of suicidality (none, thoughts, attempts).

Main Methods:

• Analysis of data from 13,543 participants in the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC).
• Examination of sociodemographic characteristics and personality disorder prevalence based on gambling severity and suicidality.
• Logistic regression to assess the relationship between gambling severity and DSM-IV Axis II psychopathology, stratified by suicidality level.

Main Results:

• Individuals with at-risk or problem/pathological gambling exhibited higher rates of various personality disorders compared to non-gamblers.
• Logistic regression revealed a higher odds ratio for any personality disorder among at-risk pathological gamblers with no history of suicidality, particularly for cluster B disorders.
• Odds ratio interaction analysis indicated that the relationship between gambling severity and personality disorders, especially cluster B, varies significantly with suicidality status.

Conclusions:

• A complex interplay exists between suicidality, problem gambling severity, and personality disorders.
• The diminished association between gambling severity and personality disorders in individuals with some suicidality suggests suicidality mediates this relationship.
• Findings highlight the need for clinical interventions addressing suicidality in individuals with gambling disorders.
