“…10 In terms of heritability, a small number of studies in PIU using the classical twin design have demonstrated that both genetic and environmental influences are important to explain the observed PIU phenotypical variation. Those studies report genetic influences of 0-48%, [11][12][13][14] and the results are considered consistent with previous observations of behavioral genetics in addiction disorders. 15 Indeed, the molecular genetics considered to influence PIU have also been associated with substance use and addiction; 1 studies looking at molecular genetic influences of PIU have explored the influences of those addiction-related variants in the serotonin transporter gene (5HTTLPR/SLC6A4), 16 nicotine acetylcholine receptor gene (CHRNA4), 17,18 and neurotrophic tyrosine kinase type 3 receptor gene (NTRK3).…”

“…While PIU was characterized by worse performance in multiple cognitive domains, we found no evidence that any of the genetic variants tested had any significant impact on those associations. This null finding implies that the genetic heritable components of PIU shown in previous studies [11][12][13][14] may not lie within the genetic loci influencing COMT function and cognitive performance, or that the genetic component in PIU involves many genetic polymorphisms each conferring only a small effect viewed individually.…”

Problematic internet use: an exploration of associations between cognition and COMT rs4818, rs4680 haplotypes

ObjectiveProblematic internet users suffer from impairment in a variety of cognitive domains. Research suggests that COMT haplotypes exert differential effects on cognition. We sought to investigate differences in the genetic profiles of problematic internet users and whether those could shed light on potential cognitive differences.MethodsWe recruited 206 non-treatment seeking participants with heightened impulsive traits and obtained cross-sectional demographic, clinical, and cognitive data as well as the genetic haplotypes of COMT rs4680 and rs4818. We identified 24 participants who presented with problematic internet use (PIU) and compared PIU and non-PIU participants using one-way analysis of variance (ANOVA) and chi square as appropriate.ResultsPIU was associated with worse performance on decision making, rapid visual processing, and spatial working memory tasks. Genetic variants were associated with altered cognitive performance, but rates of PIU did not statistically differ for particular haplotypes of COMT.ConclusionThis study indicates that PIU is characterized by deficits in decision making and working memory domains; it also provides evidence for elevated impulsive responses and impaired target detection on a sustained attention task, which is a novel area worth exploring further in future work. The effects observed in the genetic influences on cognition of PIU subjects imply that the genetic heritable components of PIU may not lie within the genetic loci influencing COMT function and cognitive performance; or that the genetic component in PIU involves many genetic polymorphisms each conferring only a small effect.

“…Potential genetic contributions to Internet addiction and IGD are related to the dopamine (Han et al, 2007 ), the serotonin (Lee et al, 2008 ), and the cholinergic system (Montag et al, 2012 ). Studies have revealed that variance of Internet addiction symptoms might be linked to genetic contributions by up to 48%, although there is also a meaningful variance across studies (Deryakulu and Ursavas, 2014 ; Li et al, 2014 ; Vink et al, 2016 ; Hahn et al, 2017 ). Results are nevertheless comparable with what is known about the genetic contribution to other psychological disorders including substance-use disorders (Egervari et al, 2017 ) and gambling disorder (Nautiyal et al, 2017 ).…”

Although, it is not yet officially recognized as a clinical entity which is diagnosable, Internet Gaming Disorder (IGD) has been included in section III for further study in the DSM-5 by the American Psychiatric Association (APA, 2013). This is important because there is increasing evidence that people of all ages, in particular teens and young adults, are facing very real and sometimes very severe consequences in daily life resulting from an addictive use of online games. This article summarizes general aspects of IGD including diagnostic criteria and arguments for the classification as an addictive disorder including evidence from neurobiological studies. Based on previous theoretical considerations and empirical findings, this paper examines the use of one recently proposed model, the Interaction of Person-Affect-Cognition-Execution (I-PACE) model, for inspiring future research and for developing new treatment protocols for IGD. The I-PACE model is a theoretical framework that explains symptoms of Internet addiction by looking at interactions between predisposing factors, moderators, and mediators in combination with reduced executive functioning and diminished decision making. Finally, the paper discusses how current treatment protocols focusing on Cognitive-Behavioral Therapy for Internet addiction (CBT-IA) fit with the processes hypothesized in the I-PACE model.

“…The results of studies on the severity of Internet addiction among young people are alarming but at the same time are characterised by significant variance, which is most likely due to the diverse assessment tools and research methodologies applied, as well as to differences between study groups [ 1 , 2 , 3 , 4 ]. For instance, in Africa, 3.3% of young people meet the criteria for Internet addiction [ 5 ].…”

Among the many contributing factors in addictions there are also those describing the individual characteristics and ways of dealing with various life challenges. Despite numerous studies in this area, there is still no unambiguous data on the nature and specificity of this relationship in different age groups. The aim of the study was to assess the relationship between personality dimensions and strategies of coping with stress and the level of Internet addiction. The study was funded by the Ministry of Health under grant no. 93/HM/2015. The study was carried out in a group of 383 persons aged 15 to 19 (M = 16.6, SD = 0.77) attending secondary schools. The following research tools were used: Ten Item Personality Measure, Brief Cope and Internet Addiction Test. Both specific personality traits and styles of coping with stress are related to the addiction to the analysed medium. The personality traits most strongly associated with the risky Internet use were conscientiousness and emotional stability. An association was demonstrated between Internet addiction and the use of coping strategies, such as disengagement, substance use and self-blame. The results obtained demonstrate a major role of personality-related factors in the development of Internet addiction. The attitude to difficulties seems to be the key issue. The findings presented also make it possible to delineate the areas for improvement (e.g., through psychoeducational interventions) to protect young people from the risk of developing the addiction.
