    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.

    Relationship 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, Nilay
    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
    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.

    Relationship 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, Merve
    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.
