Disability Benefit and Gambling Disorder: A Longitudinal Study Based on National Registry Data.

Rates of gambling disorder (GD) have been found to be higher among people receiving disability benefit, but few studies have investigated whether receiving disability benefit prospectively actually increases the risk of GD. The present study investigated whether those with a disability benefit had an increased risk of developing GD using a case-control design. The study sample was retrieved from the Norwegian Patient Registry (NPR, N = 5,131) and consisted of all adults in Norway (18 years and older) who had received a GD diagnosis (F63.0 according to ICD-10) between 2008 and 2018. The study group was age and sex matched with a random sample from the (1) general population (FD-trygd, n = 30,164), and (2) and individuals with other somatic or psychiatric illnesses (NPR, n = 30,476). The results of logistic regression analysis showed that people receiving disability benefit had higher odds of later being diagnosed with GD compared to the general population (odds ratio [OR] = 2.27, 95% CI [2.02, 2.54]), and compared to individuals in the NPR (OR = 2.13, 95% CI [1.90, 2.38]). Recipients of disability benefit constitute a group who is vulnerable in terms of developing GD. Although the present study found evidence for a prospective association, causality could not be established. The study identified a cohort that may benefit from targeted prevention and intervention strategies regarding gambling behavior.
