Interpersonal factors associated with suicide ideation among gamblers

Area of Science:

• Psychology
• Public Health
• Addiction Research

Background:

• Problem gambling is a significant public health concern associated with increased suicidality.
• The interpersonal theory of suicide offers a framework to understand the psychological mechanisms linking these issues.

Purpose of the Study:

• To investigate the role of perceived burdensomeness and thwarted belongingness in the relationship between problem gambling and suicidal ideation.
• To explore the mediating effects of debt stress and the moderating role of gambling in isolation.
• To examine the specificity of these mechanisms by comparing problem gambling with heavy drinking.

Main Methods:

• Mediation and moderated mediation analyses were conducted on data from 598 survey workers with past-year gambling experience.
• The study utilized crowdsourced survey data to assess problem gambling, suicidal ideation, perceived burdensomeness, thwarted belongingness, debt stress, and heavy drinking.
• Statistical models controlled for depression severity and examined the interplay of household breadwinner status.

Main Results:

• Perceived burdensomeness mediated the link between problem gambling and suicidal ideation, particularly when combined with thwarted belongingness.
• Debt stress mediated the relationship between problem gambling and perceived burdensomeness.
• Problem gambling predicted thwarted belongingness, but this was not significantly stronger for individuals gambling in isolation. These mediational roles were not observed for heavy drinking.

Conclusions:

• The interpersonal theory of suicide effectively explains suicidal ideation in the context of problem gambling.
• Interventions should address perceived burdensomeness and thwarted belongingness, and consider family involvement in treatment.
• Findings underscore the distinct psychological pathways linking problem gambling to suicidality compared to heavy drinking.
