The similarity between gambling disorder (GD) and Internet gaming disorder (IGD) has been long postulated and subsequently studied with a main focus on comparing the mechanisms. Although plenty of studies have investigated the psychiatric comorbidity of either GD or IGD, a comparison of the psychiatric comorbid patterns of the two remains an understudied field, especially among Chinese community populations. The present study conducted a telephone survey between October and November of 2016 and sampled 1000 representative Chinese adults (56% females and aged 18-96 years) to explore the psychiatric comorbid patterns of GD and IGD. As hypothesized, similar psychiatric comorbid patterns of the two have been found when taking account of the types of comorbidity. Both GD and IGD can increase one’s proclivity to probable depression and probable anxiety, and vice versa. When looking closer into the level of increased risk, probable IGD sub-sample (n = 20) showed higher rates of probable depression (30.0%) and probable anxiety (50.0%) compared to those observed in GD sub-sample (n = 19, 26.3% probable depression, and 37.0% probable anxiety). These results indicate Chinese IGD gamers may be at greater risk for mental distress than GD gamblers albeit a similar psychiatric comorbid pattern between the two.
