Aims
To develop a comprehensive etiological model of pathological gambling (PG) for men and women based on Kendler's development model for major depression, which groups 22 risk factors in 5 developmental tiers (childhood, early adolescence, late adolescence, adulthood, last year). We hypothesized that: 1) All risk factors would be significantly associated with PG; 2) The effect of risk factors in earlier developmental tiers would be accounted for by later tiers; and, 3) There would be few gender differences.
Design
Separate models were built for lifetime gambling and for 12-month PG among those with lifetime gambling.
Setting
Data drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) in the USA.
Participants
Respondents to NESARC Wave 1 (n= 43093).
Measurements
Odds ratios (OR) and Adjusted OR (AOR) were used to determine the risk factors in multiple models.
Findings
After mutually adjusting for other risk factors, family history of substance use disorders (SUD) or depression, impulsivity, childhood-onset anxiety, number of Axis I and II disorders, history of SUD, nicotine dependence, social deviance in adulthood, and past-year history of SUD, nicotine dependence, and independent stressful life events predicted lifetime gambling. Past history of PG, number of personality disorders and past year nicotine dependence were significantly associated with 12-month PG (all p<.05). There were no significant gender interactions for 12-month PG.
Conclusions
A modification of Kendler's model for major depression provides a foundation for the development a comprehensive developmental model of pathological gambling. Lifetime history of gambling and 12-month pathological gambling appear to be determined by risk factors in several developmental levels, with the effect of earlier development tiers accounted for by later ones.
