Article Citation - WoS: 2The 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, HulyaObjective: 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.Article Citation - WoS: 11Citation - Scopus: 12Relationship of Internet Gaming Disorder Severity With Symptoms of Anxiety, Depression, Alexithymia, and Aggression Among University Students(Kare Publ, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayObjective: 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.Article Citation - WoS: 6Citation - Scopus: 4Predictors of Stress Generation in Turkish Young Adults: the Role of Rumination and Excessive Reassurance Seeking(John Wiley & Sons Ltd, 2020) Tuna, EzgiThe stress generation model posits that not only stressful life-events predict depressive symptoms, but also depressive-prone individuals think and behave in ways that make them more vulnerable to experience life-stress. Evidence has supported the bi-directional relationship between stress and depressive symptoms, and there has been an attempt in identifying vulnerability factors for stress generation. Yet, there is a need for studies focusing on multiple risk factors and a replication of findings in non-Western samples. The aim of the present study was to examine the role of rumination and excessive reassurance seeking (ERS) in stress generation in a sample of Turkish young adults. A sample of 318 Turkish college students reported on their rumination, ERS, intensity of stressful life-events and depressive symptoms. A subsample of 162 participants also completed a measure of life-events 5 months later. Cross-sectional results showed that rumination and ERS contribute to life-stress over and above depressive symptoms and gender. Mediational analyses indicated that ERS does not mediate the relationship between rumination and life-stress at 5 months. Rather, rumination fully mediated the relationship between ERS and future life-stress. Results provide evidence for stress generation, and highlight the interconnection between rumination and ERS.Article Citation - WoS: 13Citation - Scopus: 14Relationship 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, NilayObjective: 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.Article Citation - WoS: 9Citation - Scopus: 9Relationship Between Internet Gaming Disorder Symptoms With Attention Deficit Hyperactivity Disorder and Alexithymia Symptoms Among University Students(Turkish Green Crescent Soc, 2020) Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Elhai, Jon D.; Evren, Cuneyt; Topcu Bulut, Merve; Topcu-bulut, MerveThe 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.Article Tıp fakültesi öğrencilerinde akıllı telefon bağımlılığı ile depresyon, obsesyon-kompulsiyon, dürtüsellik, aleksitimi arasındaki ilişki(2017) Özen, Seçil; Topcu, MerveBu çalışmanın amacı tıp fakültesi öğrencilerinde depresyon, obsesif-kompulsif semptomlar (OKS) ve dürtüsellik kontrol edildiğinde Akıllı Telefon Bağımlılığı (ATB) ile aleksitimi arasındaki ilişkiyi araştırmaktırArticle Citation - WoS: 25Citation - Scopus: 28The 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, NilayThe 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.Article 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, NilayObjective: 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.

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.Article Citation - WoS: 36Citation - Scopus: 45Relationships 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, NilayThe 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.Article Citation - WoS: 49Citation - Scopus: 53Relationship of Internet Addiction Severity With Probable Adhd and Difficulties in Emotion Regulation Among Young Adults(Elsevier Ireland Ltd, 2018) Kutlu, Nilay; Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, MerveThe 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.
