Bullying as a Group Process: Investigation of Participant Roles in Terms of Social Status and Gender
(Turkish Psychologists Assoc, 2015) Topcu, Aysun Ergul; Donmez, Ali
This study mainly aims to test the participant roles approach on Turkish sample suggesting that bullying is a group process. In this regard, students' ways of involving in bullying and the extent to which children are aware of their participant roles and whether these participant roles differentiate in terms of gender and social status was investigated. A total of 774 students (384 females and 390 males), from 6(th), 7(th) and 8(th) grades of 11 different primary schools in Ankara participated in the study. The results showed that 74% of all children involved in one of the participant roles as bully (11.5%), assistant-reinforcer (10.9%), defender (21.1%), outsider (20.9%) and victim (9.7%). The examinations of the relations between self-reported and peer-reported scores of participant roles revealed that children were aware of their roles in the bullying situations, however, they significantly underestimated their roles in bully and assistant-reinforcer scales while overestimated their roles in the defender and outsider scales. Boys are more actively involved in bullying process than girls; boys participated most frequently in the roles of bully, assistant-reinforcer and victim while girls participated most frequently in the defender and outsider roles. In terms of the findings related to social status, victims were the least accepted and most rejected group among their peers although they did not differentiate from bullies and assistant-reinforcer in this sense. Besides, the victims were

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
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.
Direct and Indirect Relationships Between Cognitive Flexibility and Covid-19 Related Psychological Distress: the Mediating Role of Maladaptive Cognitive Emotion Regulation Strategies
(Klinik Psikiyatri dergisi, 2022) Sayinta, Senanur; Kocak, Hatice Nur; Kaynak, Hande
Objective: The effects of the COVID-19 pandemic are remarkable on individuals' mental health. During the COVID-19 pandemic, there is an increase in mental health problems and psychological distress in uninfected healthy people. The present study aimed to examine the mediator role of maladaptive cognitive emotion regula-tion strategies in the relationship between cognitive fle-xibility and COVID-19 related psychological distress experienced during the current pandemic. Method: The sample consisted of 351 young adults (86% female and 14% male) who were not infected with COVID-19 aged between 18 to 25 years old. Participants completed the self-report questionnaires, including the Cognitive Flexibility Inventory, Cognitive Emotion Regulation Questionnaire, and COVID-19 Related Psychological Distress Scale. Mediation analysis estimated total, indi-rect, and direct effects between cognitive flexibility and COVID-19 related psychological distress. Results: The correlation analyses showed that cognitive flexibility -control dimension was negatively associated with both COVID-19 related psychological distress and maladaptive cognitive emotion regulation strategies. Also, maladap-tive cognitive emotion regulation strategies and COVID-19 related psychological distress was found to be posi-tively correlated. In the study sample, the results of the bootstrap mediation indicated that maladaptive cogni-tive emotion regulation strategies, including self-blame, acceptance, rumination, catastrophizing, and blaming others, fully mediated the relationship between cogni-tive flexibility -control and COVID-19 related psycholog-ical distress. Discussion: Our findings would help psy-chological interventions designed for COVID-19 unin-fected healthy people who have lower-level cognitive flexibility -control dimension by highlighting the promi-nence that the fewer people use maladaptive cognitive emotion regulation strategies, the less they feel COVID-19 related psychological distress.
Does a Correlation Exist Between Fluid Intelligence and Creativity
(Cyprus Mental Health Institute, 2020) Yazihan, N.T.
The aim of the study was to investigate the associations between fluid intelligence and creativity among young adults. The sample consisted of 26 university students who were recruited through convenience sampling method. The Raven Standard Progressive Matrices (RSPM) 9 item-form and a divergent thinking test were used to measure fluent intelligence and creativity, respectively. In order to examine the associations between creativity and fluent intelligence correlational analysis was applied. The Pearson’s correlation coefficient revealed that there was no significant relationship between the tests of divergent thinking and RSPM total score. On the other hand, the results showed a significant positive correlation between the RSPM visuospatial factor and both fluency (r=.47, p<.01) and flexibility (r=.41, p<.01) dimensions of the divergent thinking test. As a result, we suggest that certain basic processes regarding fluid intelligence (e.g. visual spatial reasoning) and creativity operate through common and similar mechanisms. Future studies could investigate the association between these constructs by using neuro-imagining method and focus on how these skills can be integrated into real life situations. © 2020, Cyprus Mental Health Institute.

Internet Gaming Disorder and Treatment Approaches: a Systematic Review
(Turkish Green Crescent Soc, 2018) Nazligul, Merve Denizci; Bas, Samet; Akyuz, Zeynep; Yorulmaz, Orcun
The purpose of this systematic review is to investigate the phenomenology of the psychiatric diagnosis of Internet Gaming Disorder (IGD), which has a serious potential, through the physical and psychosocial impacts of recent candidates for its diagnosis, followed by current treatment approaches for this problem. Using specific terms, a comprehensive database search of PsychINFO, ScienceDirect, Wiley Online Library, Web of Science, and PubMed was conducted to access particular studies that examine treatment interventions for IGD. All searches have been limited to full text papers published between 2000 and 2017. Six eligible treatment studies fulfilling the criteria of preferred reporting items for systematic reviews and meta-analyses (PRISMA) as an international guideline were included in the literature review. The evaluation criteria of the IGD were observed to differ among studies and the current samples to consist predominantly of males in adolescence to young adulthood. The findings on interventions indicate that different treatment modalities show successful results in reducing IGD symptoms and the time spent playing games, as well as on addictive individuals' progress regarding verbal expression. The general impressions of this systematic review are that although technology seems to facilitate life, Internet use and gaming habits at the same time can easily turn into a serious psychiatric problem. On the other hand, relatively little is known about IGD with a rather limited number of studies describing, assessing, and treating this problem. However, increasing information about this disorder is crucial for developing specific interventions. Thus, conducting additional research in Turkey as well as the world is essential for understanding IGD's nature and how to treat it.

Investigation of the Psychometric Properties of the Turkish Form of Subjective Memory Complaints Questionnaire
(Gunes Kitabevi Ltd Sti, 2013) Ozel Kizil, Erguvan Tugba; Baştuğ, Gülbahar; Duman, Berker; Altintas, Ozge; Kirici, Sevinc; Bastug, Gulbahar; Baran, Zeynel; Altunoz, Umut; Psikoloji
Introduction: Amnestic type of mild cognitive impairment (MCI) is characterized by the presence of subjective memory complaints and impairment of memory tests. This study aims to investigate the validity and reliability of the Turkish Version of the Subjective Memory Complaints Questionnaire (SMCQ). Materials and Method: The study sample consisted of 45 MCI patients and 44 healthy elderly controls. The SMCQ is a 14-item, "yes-no" questionnaire which evaluates the severity of subjective memory complaints. The discriminant validity of SMCQ was evaluated by comparing the scores of the two groups. For concurrent validity, the correlations between SMCQ and two widely-used cognitive screening tests (MMSE and ADAS-Cog) were calculated. ROC analysis was performed to test the diagnostic validity. For reliability analysis, internal consistency was calculated. Results: SMCQ scores of the patients were higher than the controls. SMCQ scores of the subjects were positively correlated with ADAS-Cog and negatively correlated with MMSE scores. Cronbach's value was 0.83. ROC analysis yielded a sensitivity of 80% and a specificity of 66% (cut-off=4.5). Area under the curve was 0.843. Conclusion: SMCQ is a valid and reliable instrument that can be used for the assessment of SMC in elderly patients. However, community based studies should be carried out for suggesting SMCQ as a screening tool.
Losing the Life: a Review on Autobiographical Memory in Alzheimer's Disease
(Istanbul Univ, Fac Letters, dept Psychology, 2021) Aydin, Oyku; Cengil, Betul Beyza; Kaynak, Hande
Alzheimer's disease (AD), the most common type of dementia among older adults, is a progressive and neurodegenerative brain disease. AD is characterized by progressive memory impairments, but not other types of dementia. Autobiographical memory (AM) is defined as episodes recollected from individuals' life, and it is one of the memory systems impaired in AD. One consequence of AM decline in AD is difficulties in the retrieval of recent AMs rather than past ones. AM contains both episodic and semantic components, and it is crucial for self-concept. The aim of the present study is to review the current understanding of AM in people with AD. In the introduction part of the review, AD and its cognitive correlates are presented in detail, with how AM performance is important for the self. In the second part of the review, AM deteriorations in patients with AD are discussed. Factors, such as emotion and olfaction, affecting AM are mentioned along with the neural substrates. In this regard, the effect of the emotional dimension (e.g., valence) on the formation and retrieval of AMs is discussed and how AM is studied with olfactory stimuli is presented, respectively. Studies on the link between AM and emotion have shown that there is a positive shift of AM in AD, indicating that patients with AD remember their AMs more positively. In addition, olfactory stimuli evoke more AMs than verbal and visual stimuli. The conclusion section of the current review is devoted to some recommendations that might guide future research. For instance, stage-by-stage investigation of AM in AD and the comparison of them in relation to relevant variables could be one way of providing detailed findings on the nature of AM in AD.

Mediating Effects of Self-Esteem in the Relationship Between Attachment Styles and Social Media Addiction Among University Students
(Kare Publ, 2020) Demircioglu, Zeynep Isil; Kose, Asli Goncu
Objective: In the present time, internet and social media have become indispensable parts of our lives. Apart from the advantages of social media, some individuals have begun to suffer from Social Media Addiction (SMA) which is associated with dysfunctions in academic and/or work domains. Although outcomes of SMA have been relatively widely investigated, its predictive factors have not been studied extensively yet. The aim of the present study was to investigate the effects of secure, fearful, and preoccupied attachment styles on SMA and the mediating role of self-esteem in the links between attachment styles and SMA. Method: Data were collected from 455 university students (300 females, 155 males) who volunteered to complete the survey package that included SMA Scale, Relationships Questionnaire, and Rosenberg Self-Esteem Scale. Results: The data were analyzed using Structural Equation Modeling and moderated multiple regression. The results revealed that preoccupied and fearful attachment had significant positive direct effects on SMA. While the link of preoccupied attachment with SMA was partially mediated, the relationship between secure attachment and SMA was fully mediated by self-esteem. In addition, exploratory analyses revealed that gender moderated the relationship between self-esteem and SMA. Conclusion: The findings of this study suggest that fearful attachment and preoccupied attachment can be risk factors for SMA among university students. On the other hand, being securely attached and having high self-esteem can be protective factors for SMA.

The Mediating Role of Cognitive Flexibility in the Relationship Between Metacognition and Psychological Health: a Study in a Non-Clinical Sample
(Kare Publ, 2021) Aydin, Oyku; Kaynak, Hande
Objective: Metacognition is a concept that refers to the awareness and control of individuals' cognitive processes. In this regard, metacognitive processes may promote cognitive flexibility. The present study investigates the impact of metacognitions on adults' psychological health and the mediating role of cognitive flexibility through bootstrap analysis. Method: The sample comprised of 212 university students. All volunteers had no history of psychiatric/neurological disorders and no use of medication affecting the central nervous system for the last six months. Participants were required to complete the Metacognitions Questionnaire-30, the General Health Questionnaire- 12, and the Cognitive Flexibility Inventory via an online survey. Results: According to the correlation analyses, cognitive flexibility was found to be negatively correlated with dysfunctional metacognition (r=-0.227, p<0.01) and poor psychological health (r=-0.397, p<0.01); dysfunctional metacognition was positively correlated with poor psychological health (r=0.399, p<0.01). We conducted mediation analyses via the bootstrapping method using a 95% confidence interval and 5000 bootstrap samples. The results showed that cognitive flexibility had a significant partial mediating role in the relationship between metacognition and psychological health [R-2=0.26, F(2, 209)=36.38, p<0.001]. Conclusion: The findings highlighted the importance of cognitive flexibility as an underlying mechanism through the relationship between metacognition and psychological health in a non-clinical sample. The results suggested the need to take "cognitive health" into account while attempting to promote "psychological health."
Mediating Roles of Impulsivity and Risk-Taking in the Links of the Dark Triad With Flirting and Dating Via Social Media
(Istanbul Univ, Fac Letters, dept Psychology, 2022) Demircioglu, Zeynep Isil; Goncu-Kose, Asli
With the acceleration of communication and access to information, individuals have begun to date via social networking sites. Although online dating has spread among university students recently, studies on this topic are very limited. The present study aimed to investigate the effects of the Dark Triad personality traits (i.e., Machiavellianism, psychopathy, and narcissism) on using Social Networking Sites (SNS) to find partners and face-to-face meeting/dating after flirting via the internet (i.e., face-to-face dating with a partner met via SNS). Furthermore, it was also aimed to identify the mediating roles of risk-taking and impulsivity in the relationships mentioned above. Data were collected from 358 University students (223 females and 135 males) who volunteered to complete the survey packages. The data was analyzed using Structural Equation Modeling (SEM). The age of the participants ranged between 18 and 49 (M = 22.67, SD = 2.83). The results revealed that narcissism was linked to using SNS to find partners, and impulsivity fully mediated the relationships of Machiavellianism with using SNS to find partners. In addition, the links of psychopathy with using SNS to find partners were partially mediated by impulsivity, with risk-taking fully mediating the effects of psychopathy and narcissism on face-to-face dating with a partner met via SNS. The present research revealed that impulsivity and risk-taking were the common attitudes underlying the links of psychopathy and narcissism with dating someone met via SNS. For individuals who score high on Machiavellianism, a low level of impulsivity is a protective factor; whereas a high level of impulsivity is a triggering factor that leads those with high psychopathy scores to search for partners via SNS. Contrary to expectations, narcissism was not directly associated with face-to-face dating a partner who was met via SNS. This finding may be related to the unidimensional measurement of narcissism, since grandiose narcissism is more likely to be positively associated with this risky and confident behavior, whereas vulnerable narcissism is less likely to have such an association.

The Mediator Effects of Positive and Negative Affectivity on the Relationship Between Optimism-Pessimism and Satisfaction With Life
(Hacettepe Univ, 2013) Ugurlu, Ozanser; Uğurlu, Ozanser; Psikoloji
This study examined the mediation effects of positive and negative affectivity on the relationship between optimism/pessimism and satisfaction with life among university students. Participants were 95 female and 151 male undergraduate students (N = 246). Participants ranged in age from 18 to 26 with a mean of 21.09 (SD = 2.34). Participants completed Life Orientation Scale (LOT), Positive and Negative Affect Schedule (PANAS), and Life Satisfaction Scale. Results of correlational analyses demonstrated that the association between optimism and pessimism was -.40. Optimism was significantly associated with PA (r = .40), NA (r = -.26), and satisfaction with life (r = .36). Similarly, pessimism was significantly correlated with PA (r = -.26), NA (r = .39), and satisfaction with life (r = -.30). Finally, optimism had statistically significant direct and indirect links (by means of positive affectivity) with satisfaction with life, whereas pessimism only had statistically significant direct link with life satisfaction.

The Mediator Role of Positive and Negative Affect in the Relationship Between Sleep Quality, Depressive Symptoms and Anxiety in Young Adults
(Galenos Publ House, 2022) Yazihan, Naksidil; Tuna, Ezgi; Fidantek, Hulya
Objective: It is known that individuals with poor sleep quality show significantly more depression and anxiety symptoms. It is important to investigate possible factors that may make individuals more vulnerable to develop depression and anxiety. For this purpose, the possible mediator roles of positive affect (PA) and negative affect (NA) in the relationship between sleep quality and depression- anxiety symptoms in young adults were tested by using multiple mediation analysis. Materials and Methods: The sample of the study consisted of 387 volunteer participants aged between 18 and 35 years (mean=22.83, standard deviation=3.20). Data consisting of Pittsburgh sleep quality index, positive and negative emotion scale, and brief symptom inventory were collected through an online computer-assisted protocol. Results: Significant positive correlations were found between low sleep quality scores and both depressive and anxiety symptoms. According to the two mediator variable models, low sleep quality influenced depressive symptoms indirectly through PA and NA, and anxiety through only NA. Alternative models of the results showed that depressive symptoms influenced sleep quality partially through PA and NA, while anxiety mediated this relationship only through PA. Conclusion: Alternative models tested to understand the direction of the relationship between depressive-anxiety symptoms and sleep quality. Although the results were significant, the explained variance was found to be less explanatory than the first and second models. The results of the study supported the idea that sleep quality, PA and NA should be targeted while developing prevention and intervention programs for depression and anxiety.

Metacognitive Beliefs and Coping Strategies of Suicide Attempters
(Yerkure Tanitim & Yayincilik Hizmetleri A S, 2019) Yazihan, Naksidil Torun; Cinar, Orhan; Canbaz, Hayri; Ak, Mehmet
Objective: Metacognition is an essential process regarding decision-making and coping with stressful life events. In this present study, we aimed to examine the metacognitive beliefs and coping strategies of suicide attempters with subthreshold depressive symptoms. Methods: Thirty suicide attempters (mean age of 25.50 +/- 7.66 years) with subthreshold depressive symptoms and 30 healthy participants (mean age of 28.27 +/- 7.13 years) were compared with regard to Metacognition Questionnaire-30 (MCQ-30) and COPE Questionnaire. Results: The MANOVA results revealed significant differences between the groups for the subscales of MCQ-30 namely, "negative beliefs about thoughts", "need to control thoughts" and "lack of cognitive confidence". The results also indicated significant difference regarding "positive reinterpretation", "seeking social support for instrumental reasons", "active coping, planning, and problem-focused coping", "behavioral disengagement", "alcohol-drug disengagement" and "dysfunctional coping" subscales of COPE Questionnaire. In addition, moderate correlations were found between the MCQ-30 and the COPE subscales based on the Pearson's correlation coefficients. Conclusions: This study revealed the effect of particular metacognitive beliefs and type of coping style on suicidal behavior. This study is important for identifying risk factors and explaining how metacognitive beliefs and coping strategies are related to suicidal behavior. Maladaptive metacognitions may lead to overestimation of perceived stress and underestimation of cognitive resources and coping skills which may prevent individulas to produce adaptive coping strategies against stressful life events.

Misinterpretations of Intrusions, Obsessive Beliefs and Thought Control Strategies in Patients With Obsessive-Compulsive Disorder
(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2013) Bastug, Gulbahar; Tuzer, Verda; Goka, Erol; Yorulmaz, Orcun
Objective: Misinterpretations of intrusive experiences are suggested to play critical role in the development and maintenance of obsessive-compulsive disorder (OCD). Some faulty belief domains are also assumed to contribute to the immediate misappraisal of intrusions and thus, patients with OCD try to control their thoughts with various thought control strategies. This study aims to examine these cognitive concepts among Turkish patients with OCD and comparatively review the psychometric characteristics of three instruments in clinical samples. Methods: The sample of the study was constituted of patients with OCD and any other anxiety disorders and undergraduate university students as control group. An instrument set on immediate misinterpretations, beliefs, control strategies, responsibility attitudes, fusions of thoughts and actions, thought suppression, OCD symptoms, self-esteem and personality characteristics was administered to the sample. Results: Having acceptable reliability values, instrument tools of immediate interpretations, beliefs and thought control methods were found to be higher in OCD patients. These three factors were found to be significantly associated with other relevant cognitive correlates, while they were not related to some other factors such as psychoticism. Conclusion: These findings show that misinterpretations of intrusions, beliefs and control methods are also valid concepts in Turkish clinical samples that live in a different cultural context, and the self-report instruments of these cognitive factors were shown to display satisfactory psychometric properties.

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
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.

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
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.

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
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.
