Research examining Internet Gaming Disorder (IGD) has increased substantially over the past decade. One of the risk factors for IGD includes poor impulse control. The present study comprises the first ever systematic review of studies examining the relationship between IGD and impusivity utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A literature search was conducted via EBSCO (which included the following academic databases: Academic Search Complete, PsycARTICLES, and PsycINFO), PubMed, ScienceDirect, Web of Science, and Wiley Online Library. The inclusion criteria were (i) publication date between 2000 and 2019, (ii) being an empirical study that collected primary data, (iii) written in English and Turkish languages (the two languages spoken by the authors), (iv) published in a scholarly peer-reviewed journal, and (v) conducted an objective assessment of both IGD and impulsivity. Following these procedures, 33 eligible empirical studies remained for evaluation in the present review comprising 18,128 participants in total. Results demonstrated that despite many methodological weaknesses, 32 studies reported a positive association between impulsivity and IGD. Possible explanations for this consistent finding appear to indicate that altered neurobiological structures detected in participants with impulsivity may explain some of the relationships between impulsivity and internet gaming disorder.

For most individuals, videogame playing is a fun and enjoyable activity that brings many benefits. However, for a small minority, the activity can be problematic and has led to much research into “gaming disorder.” In explanations concerning the contributory factors to gaming disorder, personality traits have been increasingly studied. The present paper carried out a systematic review of available literature using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The inclusion criteria were (i) publication date between 2000 and 2018, (ii) being an empirical study, (iii) written in English and Turkish languages (the two languages spoken by the authors), (iv) published in a scholarly peer-reviewed journal, and (v) conducted an assessment of IGD and personality traits objectively. Studies were excluded from the review if they were (i) single-case studies, (ii) unpublished thesis and dissertation studies, and (iii) not published in a peer-reviewed journal. Following these procedures, 21 eligible empirical studies were included. Results demonstrated that 24 distinct personality traits had been examined in relation to IGD and that some of these traits were demonstrated as risk factors for gaming addiction (although not always in the same direction).

The aim of the current study was to examine the effects of perceived stress, difficulty in emotion regulation, dysfunctional/passive coping style and dysfunctional gaming cognitions on the development of gaming addiction on the basis of gaming motivations. The study consisted of two stages. In the first phase, 360 gamer participants between the ages of 18 and 53 were included in the study in order to adapt the Motives for Online Gaming Questionnaire and the Maladaptive Gaming-Related Cognitions Scale to our language. In the second phase, which aims to test the proposed model, there were 464 gamer participants between the ages of 18 and 60. Demographic form, Motives for Online Gaming Questionnaire, Maladaptive Gaming-Related Cognitions Scale and Internet Gaming Disorder Questionnaire were the scales conducted in both phases. In addition, Barratt Impulsivity Scale-Short Form and Depression Anxiety Stress Scale – 21 were the scales added on the first stage; Perceived Stress Scale, Difficulties in Emotion Regulation Scale – Brief Form and Coping Styles Scale were the scales added on the second stage. SPSS 22 and Lisrel 8.8 programs were used in the analysis of the data. Confirmatory Factor Analysis was carried out in the adaptation study of the relevant scales; then, Confirmatory Factor Analysis, Multiple Group Confirmatory Factor Analysis and Structural Equation Modeling were applied respectively to test the hypotheses discussed within the scope of the research in two different groups. The findings, first of all, showed that both scales are valid and reliable measurement tools that can be used in our country. In addition, the findings indicated that individuals with high motivation to gaming had difficulties in regulating their emotions when their stress levels increased, and that they used dysfunctional/passive coping styles more effectively, thus increasing their risk of gaming addiction by strengthening their dysfunctional gaming cognitions. In addition, it was found that dysfunctional coping styles and dysfunctional game cognitions were fully mediated respectively in this positive relationship between difficulties in emotion regulation and gaming addiction. The findings also showed that the perceived stress level caused difficulties in emotion regulation in individuals with low gaming motivation, but the role of passive coping styles disappeared and this difficulty in emotion regulation strengthened dysfunctional gaming cognitions and consequently increased the risk of digital gaming addiction. Moreover, dysfunctional gaming cognitions partially mediated the positive relationship between difficulties in emotion regulation and gaming addiction. Limitations, recommendations for future studies, and clinical implications were discussed.
