Stress moderates the relationships between problem-gambling severity and specific psychopathologies

Area of Science:

• Psychiatry
• Psychology
• Epidemiology

Background:

• Problem gambling is a significant public health concern.
• Comorbidity between problem gambling and various psychopathologies is well-documented.
• The moderating role of stress in this relationship requires further investigation.

Purpose of the Study:

• To investigate how perceived stress influences the association between problem gambling severity and the prevalence of Axis-I and Axis-II disorders.
• To identify specific psychopathologies and gambling severity levels where stress plays a moderating role.

Main Methods:

• Analysis of Wave-1 data from 41,869 participants in the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC).
• Utilized logistic regression to examine the odds of psychopathology in at-risk and problem gambling groups compared to non-gamblers, stratified by stress levels.
• Examined interaction effects of stress on the gambling severity-psychopathology relationship.

Main Results:

• Individuals with at-risk and problem gambling showed higher odds of multiple Axis-I and Axis-II disorders across both high- and low-stress groups.
• Stress significantly moderated the relationship between at-risk gambling and Any Axis-I/Axis-II disorders, particularly substance use and Cluster-A/B disorders.
• The association between problem gambling severity and psychopathology was stronger in the low-stress group compared to the high-stress group, especially for Cluster-B disorders.

Conclusions:

• Perceived stress explains variance in the link between problem gambling severity and specific psychopathologies, notably subsyndromal gambling.
• Stress is a crucial factor to consider in the relationship between problem gambling, substance use, and Cluster-B disorders.
