Including gaming disorder in the ICD-11: The need to do so from a clinical and public health perspective.

The proposed introduction of gaming disorder (GD) in the 11th revision of the International Classification of Diseases (ICD-11) developed by the World Health Organization (WHO) has led to a lively debate over the past year. Besides the broad support for the decision in the academic press, a recent publication by van Rooij et al. (2018) repeated the criticism raised against the inclusion of GD in ICD-11 by Aarseth et al. (2017). We argue that this group of researchers fails to recognize the clinical and public health considerations, which support the WHO perspective. It is important to recognize a range of biases that may influence this debate; in particular, the gaming industry may wish to diminish its responsibility by claiming that GD is not a public health problem, a position which maybe supported by arguments from scholars based in media psychology, computer games research, communication science, and related disciplines. However, just as with any other disease or disorder in the ICD-11, the decision whether or not to include GD is based on clinical evidence and public health needs. Therefore, we reiterate our conclusion that including GD reflects the essence of the ICD and will facilitate treatment and prevention for those who need it.

Gambling behavior among adolescents with attention deficit/hyperactivity disorder.

Impulsivity is inherent to both problem gambling and ADHD. The purpose of this study is to examine ADHD key symptoms, and gambling behaviors and problem severity among adolescents. Additionally, internalizing and externalizing behaviors exhibited among these individuals and the role of these symptoms in gambling are examined. We used a cross-sectional study design and survey 1,130 adolescents aged 12-19. Results indicated that adolescents who screened positive for ADHD were significantly more likely than non-ADHD adolescents to engage in gambling and significantly more likely to develop gambling problems. Those who screened positive as predominantly inattentive and those who screened positive for ADHD Combined (Inattention and Hyperactivity-Impulsivity) were equally likely to gamble, but the latter were twice as likely to have gambling problems. However, we found no significant interaction between the key ADHD symptoms and gambling as the severity of hyperactivity-impulsivity or inattention did not significantly differ with respect to gambling pathology. Emotional problems and depressive affect were the only variables that could significantly differentiate the ADHD types and gambling severity. Our Results highlight the clinical importance of considering the subtype of ADHD among gamblers and the greater association of depressive affect and emotional problems with gambling among adolescents.
