(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2021) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay
Objective: The objective of the study is to examine the association of probable attention deficit hyperactivity disorder (ADHD) with the increase in video gaming and the severity of disordered gaming symptoms among young adults during the COVID-19 pandemic restrictions. The second objective was to examine the mediating role of COVID-19 related dysfunctional anxiety and current age. Methods: The Adult ADHD Self-Report Scale (ASRS-v1.1), the nine-item Internet Gaming Disorder Scale- Short Form (IGDS9-SF), and the Coronavirus Anxiety Scale (CAS) were used to evaluate university students. Results: Participants with probable ADHD (n=117, 21.2%) did not differ in terms of age, gender, romantic relationship, and employment status when compared with participants without probable ADHD (n=441, 79.0%). However, they had higher scale scores (IGDS9-SF and CAS). In the hierarchical logistic regression analysis, probable ADHD predicted the increase in video gaming during the pandemic, but when the current age and the dysfunctional anxiety related with COVID-19 were included in the analysis, they were significant predictors, whereas probable ADHD was no more a predictor. While probable ADHD was associated with the symptom severity of disordered gaming in ANCOVA, COVID-19 related dysfunctional anxiety was a significant covariate. Conclusion: Findings of the current study may suggest that the relationship between probable ADHD and the increase in video gaming during the pandemic was mediated by lower age and COVID-19 related dysfunctional anxiety among young adults. Additionally, while COVID-19 related dysfunctional anxiety was a significant covariate for the severity of disordered gaming symptoms, probable ADHD was independently associated with the symptom severity of disordered gaming.

Development and psychometric validation of the Turkish gambling disorder screening test: a measure that evaluates gambling disorder regarding the American Psychiatric Association framework
(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
Objective: First study aims to develop the Gambling Disorder Screening Test (GDST), a standardized measure that assesses symptoms and prevalence of gambling disorder (GD) regarding the American Psychiatric Association (APA) diagnostic framework. The aim of the second study is to validate the GDST psychometrically. Methods: In the first study participants were assessed with GDST. Sample comprised of 400 Turkish university students and video game players (54.0% male, mean age 24.30 years, SD=6.83) that was enrolled online. In the second study the sample (n=326; 60.1% male, mean age 23.54 years, SD=4.44) was similar with the first study. Participants were assessed with GDST, the South Oaks Gambling Screen (SOGS) and the Gambling Motives Questionnaire (GMQ). Results: In the first study, according to the exploratory factor analysis a single component accounted for 64.02% of total variance. The scale was internally consistent with a Cronbach's alpha of 0.93, thus considered as reliable. In the second study, confirmatory factor analysis showed that GDST's factor structure (i.e., the unidimensional structure) was satisfactory. Positive correlations between GDST and the number of self-reported gambling type, SOGS and GMQ scores demonstrated adequate convergent and criterion-related validity. Also the GDST had a Cronbach's alpha of 0.92 in this sample. Conclusion: These findings from Study 1 and Study 2 suggest that the Turkish GDST is a valid and reliable measure to assess the severity of GD related issues according to APA's framework among young adults and for the purposes of early detection of GD in clinical settings and research.

Measuring anxiety related to COVID-19: A Turkish validation study of the Coronavirus Anxiety Scale
(Routledge Journals, Taylor & Francis Ltd, 2022) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
The aim of the current study is to validate the Turkish version of the Coronavirus Anxiety Scale (CAS). Participants were assessed across the CAS, Obsession with COVID-19 Scale (OCS) and Fear of COVID-19 Scale. We surveyed 1023 Turkish native speakers who participated online. Confirmatory factor analysis showed that the factor structure of the CAS was satisfactory. The scale was internally consistent with a Cronbach's alpha of 0.80. Positive correlations of the CAS with the OCS and the Fear of COVID-19 Scale demonstrated adequate convergent validity. These findings suggest that the CAS is a valid and reliable measure to assess the severity of dysfunctional coronavirus related anxiety.

Measuring dysfunctional grief due to a COVID-19 loss: A Turkish validation study of the Pandemic Grief Scale
(Routledge Journals, Taylor & Francis Ltd, 2022) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay
The global death toll to date of the COVID-19 pandemic has been enormous, and millions of people are grieving these losses. The aim of the current study is to validate a Turkish version of the Pandemic Grief Scale (PGS), which is a brief English-language mental health screener to identify probable cases of dysfunctional grief associated with a COVID-19 death. Participants were assessed using the PGS, Patient Health Questionnaire-4 (PHQ-4) and Work and Social Adjustment Scale (WSAS). We surveyed 758 Turkish native speakers who participated online. Confirmatory factor analysis showed that the factor structure of the PGS was satisfactory. The scale was internally consistent with a Cronbach's alpha of 0.77 and a composite reliability of 0.90. The PGS demonstrated construct validity with strong correlations with suicidal ideation and substance use coping. Positive correlations of the PGS with the PHQ-4 and the WSAS demonstrated adequate convergent validity. The PGS discriminates well between persons with and without dysfunctional grief using an optimized cut score of >= 3 (89% sensitivity and 72% specificity). The PGS also demonstrates incremental validity by explaining most of the variance (43%) in functional impairment due to a COVID-19 loss beyond measures of depression and generalized anxiety. These findings closely replicate the original validation study on the PGS in English and suggest that the current Turkish version of the PGS is a valid and reliable measure to assess the severity of dysfunctional grief associated with a COVID-19 death.

Neuroticism and introversion mediates the relationship between probable ADHD and symptoms of Internet gaming disorder: results of an online survey
(Aves, 2019) Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
OBJECTIVES: The aim of the present study was to evaluate relationship of probable attention deficit hyperactivity disorder (ADHD) with severity of the Internet gaming disorder (IGD), neuroticism and extraversion. METHODS: The study was conducted with online survey among 457 volunteered university students in Ankara and people who play games on the Internet and who are in the e-mail database of a company located in Istanbul that organizes e-sports tournaments. Participants were evaluated by applying the Adult ADHD Self-Report Scale (ASRS-v1.1), the 9-item Internet Gaming Disorder Scale (IGDS) and the Eysenck Personality Questionnaire Revised-Abbreviated Form (EPQR-A). RESULTS: Age was lower among those with the probable ADHD (n = 102, 22.3%) and those without (n = 355, 77.7%). Gender, educational status, and type of the participants did not differ between the groups. Severity of IGD symptoms and neuroticism were higher among those with the probable ADHD, whereas extraversion was lower. In logistic regression analysis, severity of IGD symptoms predicted the probable ADHD in the first Step, whereas when extraversion and neuroticism were included in the analysis as independent variables, low extraversion (introversion) and high neuroticism predicted the probable ADHD and severity of IGD symptoms was no longer a predictor. CONCLUSION: These findings suggest that the severity of IGD symptoms is related with the probable ADHD and low extraversion (introversion) and high neuroticism may have mediator effect on this relationship.

Psychometric validation of the Turkish gaming disorder test: A measure that evaluates disordered gaming according to the World Health Organization framework.
(Aves, 2020) Evren, Cuneyt; Pontes, Halley M.; Dalbudak, Ercan; Evren, Bilge; Topcu, Merve; Kutlu, Nilay; 256656
Background: Previous research on gaming disorder (GD) used psychometric tools, which evaluates according to the American Psychiatric Association (APA) diagnostic framework. The Gaming Disorder Test (GDT), a standardized measure to assess symptoms and prevalence of GD according to the World Health Organization (WHO) diagnostic framework. The main aim of the current study was to adapt the GDT to Turkish. Methods: In the present study participants were assessed with the GDT, the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the CAGE-Problematic Internet Use Questionnaire (CAGE-PIUQ). The factor structure of the scale was tested with Con.rmatory Factor Analysis (CFA), and reliability and validity analyses were conducted. Results: A sample of 932 Turkish gamers (58.3% male, mean age 23.64 years, SD=5.42) was recruited online. Confirmatory factor analyses demonstrated that the unidimensional factor structure of the GDT was satisfactory. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.879) and showed adequate convergent and criterion-related validity, as indicated by statistically significant positive correlations between average time daily spent playing games (ATDSPG) during last year, IGDS9-SF and CAGE-PIUQ scores. By applying the International Classification of Diseases 11th edition (ICD-11) threshold for diagnosing GD (e.g., meeting all four criteria by answering them either with 'often' [4] or 'very often' [5]), it was found that the prevalence of GD is 1.9% (n = 18). Conclusions: Online gaming preference, ATDSPG and probable ADHD predicted the severity of disordered gaming. These findings support the Turkish version of the GDT as a valid and reliable tool for determining the extent of GD related problems among young adults and for the purposes of early GD diagnosis in clinical settings and similar research.

Psychometric Validation of the Turkish Motives for Online Gaming Questionnaire (MOGQ) Across University Students and Video Game Players
(Turkish Green Crescent Soc, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
The main aim of the current study was to test the factor structure, reliability, and validity of the 27-Item Motives for Online Gaming Questionnaire (MOGQ), a standardized measure to assess seven types of motivation for online gaming. In the present study, participants were assessed with the MOGQ, the nine-item Internet Gaming Disorder Scale-Short Form (IGDS9-SF), and the Electronic Gaming Motives Questionnaire (EGMQ). The mean age and age at first gaming were lower and the socio-demographic factors such as male gender, living alone, having a game console, gaming more than usual in weekends, time spent on the gaming, having problems related with gaming, severity of IGD symptoms, and severity of online gaming motives were higher among the group of gamers than those in the group of students. Confirmatory factor analyses demonstrated that the six-factor structure (i.e., the dimensional structure) of the MOGQ was satisfactory for the Turkish version. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.91 for coping/escape, 0.92 for recreation, 0.88 for fantasy, 0.91 for skill development, 0.87 for social, and 0.89 for competition) and showed adequate convergent and criterion-related validity, as indicated by statistically significant positive correlations with average time daily spent playing games during last year, IGDS9-SF, and EGMQ scores. These findings support the Turkish version of the MOGQ as a valid and reliable tool for determining the motives for online gaming among young adults.

Psychometric validation of the Turkish nine-item Internet Gaming Disorder Scale-Short Form (IGDS9-SF)
(Elsevier Ireland Ltd, 2018) Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Evren, Bilge; Pontes, Halley M.; 256656
The main aims of the current study were to test the factor structure, reliability and validity of the nine-item Internet Gaming Disorder Scale-Short Form (IGDS9-SF), a standardized measure to assess symptoms and prevalence of Internet Gaming Disorder (IGD). In the present study participants were assessed with the IGDS9-SF, nine-item Internet Gaming Disorder Scale (IGDS) and the Young's Internet Addiction Test-Short Form (YIAT-SF). Confirmatory factor analyzes demonstrated that the factor structure (i.e., the dimensional structure) of the IGDS9-SF was satisfactory. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.89) and showed adequate convergent and criterion-related validity, as indicated by statistically significant positive correlations between average time daily spent playing games during last year, IGDS and YIAT-SF scores. By applying the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) threshold for diagnosing IGD (e.g., endorsing at least five criteria), it was found that the prevalence of disordered gamers ranged from 0.96% (whole sample) to 2.57% (e-sports players). These findings support the Turkish version of the IGDS9-SF as a valid and reliable tool for determining the extent of IGD-related problems among young adults and for the purposes of early IGD diagnosis in clinical settings and similar research.

(Kare Publ, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
Objective: The main aims of the current study were to test the factor structure, reliability and validity of the Ten-Item Internet Gaming Disorder Test (IGDT-10), a standardized measure to assess symptoms and prevalence of internet gaming disorder (IGD). Method: In the present study, participants were assessed with the IGDT-10, the nine-item IGD Scale - Short Form (IGDS9-SF), and the Motives for Online Gaming Questionnaire (MOGQ). Results: Confirmatory factor analysis showed that the IGDT-10's one-factor structure (i.e., dimensional structure) was satisfactory. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.79) and showed adequate convergent and criterion-related validity as shown by positive correlations between average daily time spent playing games over the past year and IGDS9-SF and MOGQ scores. By applying the DSM-5 threshold to diagnose IGD (meeting at least five criteria), the incidence of individuals with IGD was found to be 7.4% (n=56) in the entire sample. Conclusion: These results demonstrate the Turkish version of the IGDT-10 to be a valid and reliable instrument for determining the magnitude of problems associated with IGD among young adults and for early diagnosis of IGD in clinical environments and comparable studies.

Relationship between Internet Gaming Disorder Symptoms with Attention Deficit Hyperactivity Disorder and Alexithymia Symptoms among University Students
(Turkish Green Crescent Soc, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Elhai, Jon D.; 256656
The aim of the present study was to evaluate the relationship between Internet gaming disorder (IGD) symptom severity with probable attention deficit hyperactivity disorder (ADHD) and alexithymia symptoms, while controlling anxiety and depression symptoms. The cross-sectional online study was conducted with 987 volunteer university students in Ankara, Turkey. Age was lower and first. Internet use was earlier among the group with probable ADHD (n=166, 16.8%) than that without (n=821, 83.2%). There were no significant differences in gender or romantic relationship status between these groups, whereas the scale scores, duration of daily Internet gaming, and problems related to Internet gaming were higher in the probable ADHD group. Probable AMID, continuous scores on alexithymia (particularly "difficulty identifying feelings" [DIF] and "externally oriented thinking" [EOT] dimensions), depression, and anxiety symptoms were associated with higher severity of IGD symptoms. ADHD, alexithymia (as a binary variable), depression, and anxiety predicted the severity of IGD symptoms, although these effects involving probable ADHD and alexithymia did not interact. These findings suggest that probable AMID and both the severity of alexithymia (particularly DIF and EOT dimensions) and presence of probable alexithymia are related with the severity of IGD symptoms, even when controlling the effects of depression and anxiety, among university students.

Relationship of internet addiction severity with probable ADHD and difficulties in emotion regulation among young adults
(Elsevier Ireland Ltd, 2018) Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
The aim of the present study was to evaluate relationship of Internet addiction (IA) symptom severity with probable attention deficit/hyperactivity disorder (ADHD) and difficulties in emotion regulation, while controlling the effects of depression, anxiety and neuroticism. The study was conducted with online survey among 1010 volunteered participants of university students and/or amateur or professional gamers. Scale scores were higher among the group with high probability of ADHD (n = 190, 18.8%). In linear regression analysis, both Inattentiveness and hyperactivity/impulsivity dimensions of ADHD were related with the severity of IA symptoms, together with depression and non-accept dimension of the Difficulties in Emotion Regulation Scale (DERS). Similarly, presence of probable ADHD was related with the severity of IA symptoms in ANCOVA, together with depression, neuroticism and non-accept dimension of DERS. Participants were two different groups of non-clinical samples and all scales were self-rated. Also common comorbidities were not screened. Finally, since this study is cross-sectional the findings of this study cannot address the causal relationships among the primary constructs of interest. These findings suggest that the presence of probable ADHD is related with the severity of IA symptoms, together with the difficulties in emotion regulation, particularly non-accept dimension, depression and neuroticism among young adults.
Relationship of internet gaming disorder severity with symptoms of anxiety, depression, alexithymia, and aggression among university students
(Yerküre Tanıtım & Yayıncılık Hizmetleri, 2019) Evren, Cüneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
Objective: The aim of the present study was to evaluate the relationship of Internet gaming disorder severity with alexithymia and aggression among university students, while controlling for effects of anxiety and depressive symptoms. Method: The study was conducted with an online survey among 987 volunteer university students in Ankara. Participants were evaluated by administering the Toronto Alexithymia Scale (TAS-20), the Buss-Perry Aggression Questionnaire (BPAQ), the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the depression and anxiety subscales of the 90-Item Symptom Checklist-Revised (SCL-90-R). Results: Scores for the different scales mildly correlated with one other. In hierarchical linear regression analysis, both alexithymia (particularly the dimensions "difficulty identifying feelings" [DIF] and "externally-oriented thinking" [EOT]) and aggression (physical aggression) predicted the severity of Internet gaming disorder symptoms, together with severity of depressive symptoms. Conclusion: These findings suggest that among university students, the severity of alexithymia, particularly in its dimensions DDF and EOT, is related with the severity of Internet gaming disorder, together with aggression, particularly physical aggression, and depression.

Relationship of Internet gaming disorder symptom severity with non-suicidal self-injury among young adults
(Kare Publ, 2020) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
Objective: The aim of the present study was to evaluate the relationship of Internet gaming disorder (IGD) symptom severity with non-suicidal self-injury (NSSI) while controlling the effects of depression, anxiety and neuroticism among young adults. Method: The present study was conducted as a cross-sectional online self-report survey. The data were collected from 1010 volunteer Turkish university students in Ankara, persons who were in the e-mail database of a company located in Istanbul that organizes e-sports tournaments (ESL Turkey Amateur e-sport players), and Turkish gamers from gaming forums. Participants were evaluated by administering the IGD Scale-Short Form (IGDS-SF), the neuroticism dimension of the Eysenck Personality Questionnaire Revised-Abbreviated Form, the Beck Anxiety Inventory, and the Beck Depression Inventory. Results: Age and gender did not differ between participants with NSSI (n=207, 20.5%) and those without NSSI (n=803, 79.5%). IGDS9-SF, depression, anxiety, and neuroticism scores were higher among individuals with NSSI. In logistic regression analysis, severity of IGD predicted the presence of NSSI, together with depression, anxiety, and neuroticism. Conclusion: These findings suggest that the severity of IGD in young adults is related with the presence of NSSI, together with depression, anxiety, and neuroticism. Thus, early detection and treatment of these risk factors is important for reducing self-injurious behavior in this age group.

Relationships of Internet addiction and Internet gaming disorder symptom severities with probable attention deficit/hyperactivity disorder, aggression and negative affect among university students
(Springer Wien, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
The aim of the present study was to evaluate relationships of Internet addiction (IA) and Internet gaming disorder (IGD) symptom severities with probable attention deficit/hyperactivity disorder (ADHD) and aggression among university students, while controlling the effects of anxiety and depressive symptoms. The study was conducted with online survey among 1509 volunteered university students in Ankara who regularly use the Internet, among whom we conducted analyses related with IA. Among these students, 987 of them, who play video games, were included in the analyses related with IGD. Correlation analyses revealed that the severities of the scale scores were mildly correlated with each other both among students who regularly use the Internet and students who play video games. Probable ADHD was associated with the severity of IA symptoms, together with depression and aggression, particularly physical aggression and hostility, in ANCOVA analyses. Similarly probable ADHD was also associated with the severity of IGD symptoms, together with depression and aggression, particularly physical aggression, anger and hostility, in ANCOVA analyses. These findings suggest that the presence of probable ADHD is related with both severity of IA and IGD symptoms, together with aggression and depression.

Severity of dissociative experiences and emotion dysregulation mediate the relationship between childhood trauma and Internet addiction symptom severity among young adults
(Kare Publ, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Elhai, Jon D.; 256656
Objective: The first aim of the present study was to evaluate the relationship between childhood trauma and Internet addiction (IA) symptom severity. The second aim was to evaluate the mediator effects of dissociative experiences and emotion dysregulation on this relationship. Method: We conducted the study using an online survey with 920 university student participants. Participants were evaluated with the Internet Addiction Test (IAT), Dissociative Experiences Scale (DES), Childhood Trauma Questionnaire (CTQ-28), and Difficulties in Emotion Regulation Scale (DERS). Results: Compared with participants evidencing low IA risk (n=806, 87.6%), those with high IA risk (n=114, 12.4%) had a longer duration of daily Internet use and a higher rate of problems related to Internet use. The high IA risk group was connected to the Internet less through a smartphone and more through computer use. In addition, scale scores (DES, DERS and CTQ-28) were higher among the group with high IA risk. Scale scores were mildly to moderately correlated with each other. In linear regression analysis, childhood trauma (particularly emotional abuse and physical neglect) was related to severity of IA symptoms. Severity of dissociative experiences and emotion dysregulation mediated the childhood trauma-IA symptom relationship. Conclusion: These findings suggest relations between the severity of childhood trauma, particularly emotional abuse and physical neglect dimensions, and severity of IA symptoms among Turkish young adults. Severity of dissociative experiences and emotion dysregulation may also partially mediate this relationship.

The impact of depression, anxiety, neuroticism, and severity of Internet addiction symptoms on the relationship between probable ADHD and severity of insomnia among young adults
(Elsevier Ireland Ltd, 2019) Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
The aim of the present study was to evaluate the impact of depression, anxiety, neuroticism, and severity of Internet addiction symptoms (IAS) on the relationship between probable attention deficit/hyperactivity disorder (ADHD) and severity of insomnia among young adults. The study was conducted with online survey among 1010 volunteered university students in Ankara, people who are in the e-mail database of a company located in Istanbul that organizes e-sports tournaments and Turkish garners from gaming forums. Scale scores were higher among the group with high probability of insomnia (n = 200, 19.8%). Also risk of high probability of insomnia was 2.7 times higher among those with probable ADHD. In linear regression analysis, both inattentiveness and hyperactivity/impulsivity dimensions of ADHD were related with the severity of insomnia, together with severities of anxiety, depression, neuroticism and IAS. Similarly, presence of probable ADHD was related with the severity of insomnia in ANCOVA, together with severities of anxiety, depression, neuroticism and IAS. These findings suggest that the presence of probable ADHD and the severity of ADHD symptoms are related with the severity of insomnia, even after controlling the depression, anxiety, neuroticism and IAS, which are all related with the severity of insomnia, among young adults.

The Psychometric Properties of the Turkish Version of the Internet Gaming Disorder Scale
(Kare Publ, 2017) Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Evren, Bilge; 256656
Objective: The main aim of the current study was to test the psychometric properties of the Internet Gaming Disorder Scale (IGDS), both the long (27-item) and short (9-item) polytomous versions, which are survey instruments that measure Internet gaming disorder (IGD) on the basis of the 9 criteria from the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Method: Participants were evaluated by applying the 27-item IGDS and the Young's Internet Addiction TestShort Form (YIAT-SF). The psychometric properties of the IGDS were tested through an online survey completed by volunteers who are university students in Ankara, active Internet game players, as well as individuals who are in the e-mail database of an Istanbul-based company which organizes e-sports tournaments. Results: A single component on the nine-item IGDS reached the criterion of an Eigenvalue greater than one (5.926), and the variance accounted for by this component was 65.85%. Confirmatory factor analyses demonstrated that the structural validity (i.e., the dimensional structure) of the nine-item IGDS was satisfactory. This short version of the scale was also reliable (i.e., internally consistent with Cronbach's a of 0.931) demonstrating good criterion-related validity, as indicated by positive correlations with time spent playing games, and the YIATSF score. Correlation between the 27-item IGDS and the nine-item IGDS was very high (n=457; r=0.988, p<0.001). Test-retest correlation for both the 27-item IGDS (n=261, r=0.759) and nine-item IGDS (n=261, r=0.756) were high. When the DSM-5 threshold for diagnosis (experiencing 5 or more criteria) was applied, the prevalence of disordered gamers ranged between 3.9% and 9.2%, according to the cutoff point chosen for each item. Conclusion: The results of the validity and reliability testing of the Turkish version of the nine-item IGDS were found to be similar to the findings of the original scale. These findings support the Turkish versions of the nine-item IGDS, which measure a unidimensional construct as being valid and reliable IGD screening instrument in determining IGD which can become problematic among young adults and also for the purposes of early diagnosis and use in other relevant research.
