Abstract
AbstractAimStudies show gambling disorders are associated with attention‐deficit hyperactivity disorder (ADHD). The association between gambling disorders and autism spectrum disorder (ASD) has not been well studied, although ASD is often comorbid with ADHD and is associated with gaming disorder. The aim of this study was to estimate the prevalence of ASD and ADHD traits comorbid with gambling disorders and to examine the relationships between these traits and gambling problems in a clinical population.MethodsThis single‐site cross‐sectional study was conducted at a Japanese addiction outpatient clinic treating gambling disorders. The Autism‐Spectrum Quotient (AQ) test and the Adult ADHD Self‐Report Scale (ASRS) were used to screen ASD and ADHD. The Problem Gambling Severity Index (PGSI) was used to assess the severity of the gambling problems. We calculated the prevalence of suspected ASD and ADHD with 95% confidence intervals (CI) based on a binomial distribution and performed univariate analyses to examine the relationships between the AQ and ASRS scores and the total PGSI score.ResultsWe included 97 of 197 potential participants. After screening the participants using the AQ and ASRS, we found that the prevalence of ASD traits was 29.8% (95% CI: 21.0%–40.2%), while the prevalence of ADHD traits was 26.0% (95% CI: 17.9%–36.2%). Univariate regression analyses revealed that the total AQ score was inversely associated with the total PGSI score. However, the total ASRS score and some ASRS subscores were positively associated with the total PGSI score.ConclusionASD and ADHD may be prevalent among patients with gambling disorders in clinical settings.
