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.

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.
Impact of information bandwidth of in-vehicle technologies on young drivers' attention maintenance performance: A Driving simulator study
(Human Factors an Ergonomics Society Inc., 2017) Bıçaksız, Pınar
Previous research indicates that young novice drivers' ability to maintain their attention on the forward roadway during driving is poorer than experienced drivers, leading to more frequent excessively long off-road glances that elevate the risk of crashes. This study directly manipulated information bandwidth of an in-vehicle monitor and asked young drivers to perform the number judgment task during simulated driving. Results show that the drivers produced more number of off-road glances and longer summed excess glance durations in 1.5-second threshold when the in-vehicle task imposed greater information processing demand. The crash risk estimated from the obtained summed excess glance durations is 3.2 times higher when the information processing demand was high than low using the 1.5-second threshold, and 4.3 times higher using the 2.0-second threshold. In practice, designers of in-vehicle technologies should consider information-processing demands of in-vehicle tasks that the technologies require in order to minimize the frequency of excessively long off-road glances during driving
Risky Sexual Behavior Among Heterosexual Male Turkish University Students
(2021) Kıylıoğlu, Levent; Dönmez, Ali
The aim of this study was to investigate the variables influencing risky sexual behaviors of heterosexual male Turkish university students. The sample of the study consisted of 382 university students studying at Ankara University and METU. As measurement instruments demographic questionnaire, sexual sensation seeking scale, sexual risk-taking scale, religious attitude scale, HIV knowledge scale, self-efficacy scale for AIDS prevention and Bem sex-role inventory were used. In addition to descriptive analysis, correlation and regression analyses were used. Findings showed that participants’ age, having sexually transmitted infection other than HIV, getting HIV test, sexual sensation seeking level and masculinity positively predicted sexual risk taking behavior. Using condom in first intercourse, condom use self-efficacy, and the femininity negatively predicted sexual risk-taking behavior. Findings once more proved protective effect of lifelong condom use.Keywords: HIV/AIDS, Risk-taking, Sexual Behavior.
Uyku ve Açık Bellek Arasındaki İlişki
(Galenos Yayınevi, 2018) Torun Yazıhan, Nakşidil; Yetkin, Sinan
Uyku fizyolojik olarak aktif bir süreç olup bilişsel süreçlere ilişkin fonksiyonu uzun zamandır bilinmektedir. Uykunun iki farklı aşamada bellek ile ilişkili olarak kritik olduğu bilinmektedir. Birincisi öğrenme öncesi olan bilginin kodlanması aşaması; ikincisi ise öğrenme gerçekleştikten sonra yeni bilgilerin kalıcılığıyla ilişkili olan konsolidasyon aşamasıdır. Konsolidasyonun belleğin pek çok formu için evrimsel olarak korunmuş uykunun bir fonksiyonu olduğu düşünülmektedir. Bu derleme yazısının amacı uykunun mikro ve makro yapıları ile açık-deklaratif bellek süreçlerinin ilişkisini araştıran başlıca çalışma bulgularını bir araya getirmektir. Öncelikle uyku tanımlanmış, sonrasında uykunun açık bellek konsolidasyonu sürecindeki özgün rolü açıklanmıştır. Bu bağlamda öne sürülen aktif sistem konsolidasyonu ve sinaptik homeostazis hipotezleri anlatılmıştır. Uyku deprivasyonunun açık bellek ve bilgi işleme süreçleri üzerine etkilerini araştıran çalışma sonuçları özetlenmiştir. Son olarak uykunun mikro yapısını oluşturan uyku iğciği ve yavaş dalga aktivitesinin bellek süreçleri üzerindeki rolü tartışılmıştır.

Psychometric Adaption of the Impulsive Driver Behavior Scale in a Chinese Sample
(Elsevier Sci Ltd, 2020) Qu, Weina; Zhou, Mu; Ozkan, Turker; Bicaksiz, Pinar; Zhang, Kan; Ge, Yan
Impulsivity plays an important role in aberrant driving behavior and crash involvement. The purpose of this study was to evaluate the reliability and validity of the Impulsive Driver Behavior Scale (IDBS, Bicaksiz & Ozkan, 2016a) with a Chinese sample. Two hundred and ninety-nine drivers completed the Chinese version of the Impulsive Driver Behavior Scale, the Driver Behavior Questionnaire, the Big Five Inventory and some social-demographic and traffic violation items. A confirmatory factor analysis indicated that a four-factor solution with 20 items yielded a better fit to the data than other solutions. The reduced IDBS showed good reliability and a stable structure. Drivers' functional impulsivity was positively correlated with positive driver behavior and some ordinary violations. Meanwhile, the other three dimensions of dysfunctional impulsivity showed negative correlations with positive driver behavior and positive associations with aberrant driving behavior and penalty points and fines. Impulsive driver behavior is also associated with agreeableness and conscientiousness. These results provide evidence supporting the IDBS as a reliable and valuable instrument for measuring driving impulsivity in the Chinese traffic environment. (C) 2019 Elsevier Ltd.

Kronik Hastalıklarda Duygu Düzenleme: Kalp ve Damar Sistemi Hastalıkları, Kanser, Migren, Fibromiyalji ve Sedef Hastalığı Üzerine Bir Derleme
(Association for Clinical Psychology Research, 2023) Tuna, E.
Emotion regulation (ER) involves conscious and automatic regulation of the occurrence, type, intensity, timing, and expression of emotions. Previous studies indicate that ER not only affects individuals’ mental health outcomes, but also plays a critical role in physical health as well. Especially in chronic diseases, how emotions are regulated shapes many patient variables including self-care, treatment adherence, and stress management; affecting both physical and psychological well-being. Furthermore, there is evidence that ER plays a role in initiation and prognosis of some chronic diseases. The aim of this review article was to summarize evidence regarding the association between chronic diseases and ER, and describe limitations in the existing studies in order to guide future research. To reach this aim, after a brief discussion of the mechanisms between emotions and health, we discussed research findings on ER in cardiovascular disease (CVD), cancer, migraine, fibromyalgia, and psoriasis, respectively. Findings indicate that emotion and ER play a role in the etiology of CVD; yet there are mixed findings regarding their role in the etiology of cancer. Research on migraine, psoriasis and fibromyalgia are rather correlational. Findings generally suggest that individuals with a chronic disease report more problems in ER as compared to healthy individuals. Frequent use of less adaptive strategies among patients have been related to less favorable outcomes such as psychopathology symptoms, bodily symptoms, and lower quality of life. Understanding ER in chronic diseases could guide the development of prevention and intervention programs aimed at increasing patients’ quality of life. The article ends with an evaluation of the literature and suggestions for clinical practice. © 2023 Klinik Psikoloji Araştırmaları Derneği. Tüm hakları saklıdır.

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.
Bölüm Seçimine Göre Karanlık Üçlü ve Büyük Beşli Kişilik Özelliklerinin İncelenmesi
(2020) Ekren, Buse; Göncü-köse, Aslı
Karanlık Üçlü (KÜ) kişilik özellikleri, birbirleriyle ilişkili kişilik özelliklerinden Makyavelizm, narsisizm ve psikopatiyi kapsamaktadır ve araştırmalar KÜ kişilik özelliklerinde yüksek skor alan bireylerin bu kişilik özelliklerine uygun olan ödüllere/çıktılara ulaşmalarını sağlayacak meslekler seçme eğiliminde olduklarını göstermektedir. Bu bulgular ve önermeyle uyumlu olarak, KÜ kişilik özelliklerinin üniversite öğrencilerinin bölüm tercihlerini etkileyeceği önerilmektedir. Önceki araştırmalar Büyük Beşli (BB) kişilik özelliklerinin de eğitim tercihlerini etkilediğini göstermektedir. Bu çalışmanın temel amacı, kariyer seçimlerinde bu kişilik özelliklerine bağlı olarak yapılan öz-seçimlerin etkili olup olmadığını araştırmaktır. Veri, Türkiye’de yedi farklı alanda (psikoloji, hukuk, iktisat/işletme, mühendislik, siyaset bilimi, tıp ve eğitim bilimleri) henüz eğitime başlamış 659 (359 kadın) üniversite öğrencisinden toplanmıştır. Grupların değişkenlerdeki ortalamaları KÜ ve BB kişilik özelliklerinin bağımlı değişken olduğu 2 (cinsiyet)×7 (bölüm) varyans analizi yöntemiyle karşılaştırılmıştır. Sonuçlar, iktisat/işletme ve mühendislik öğrencilerinin Makyavelizm skorlarının psikoloji öğrencilerinin skorlarından daha yüksek olduğunu; ayrıca, mühendislik, iktisat/işletme ve siyaset bilimi öğrencilerinin psikopati skorlarının psikoloji öğrencilerinin skorlarından yüksek olduğunu göstermiştir. Psikoloji öğrencilerinin nevrotizm skorlarının, mühendislik, iktisat/işletme ve siyaset bilimi öğrencilerinin skorlarından daha yüksek olduğu bulunmuştur. Hukuk ve eğitim fakültesi öğrencilerinin nevrotiklik skorları da mühendislik ve iktisat/işletme öğrencilerinin skorlarından daha yüksektir. Son olarak, sonuçlar deneyime açıklık ve dürüstlük kişilik özellikleri için bölüm ve cinsiyetin etkileşim etkisinin olduğunu göstermiştir. Bulgular, kuramsal ve uygulamaya yönelik çıkarımlar ile gelecekteki araştırmalar için öneriler bağlamında tartışılmıştır.

Relations Among Emotional Mood State Personality Dimensions and Social Desirability in Older Adults
(Gunes Kitabevi Ltd Sti, 2018) Kaynak, Hande
Introduction: Previous studies have shown that older adults report higher levels of positive affect (PA). Studies in the context of the five-factor model of personality have also noted the age-related changes in personality. However, the possible influence of personality on emotional state needs further investigation in older adulthood. This study examines relations among personality traits, social desirability, and positive/negative affectivity in conjunction with aging. Materials and Method: A total of 123 volunteers (62 young and 61 older adults) was participated in the study. A cross-design was used with consecutive sampling. All participants had higher education. Participants completed the Positive and Negative Affect Schedule as a measure of emotional state. Thereafter, they rated the degree to which each item described themselves on the Five-Factor Personality Inventory, which measures personality dimensions and social desirability. Results: Independent t-tests were conducted to compare young and older adults in terms of affectivity and personality. Findings revealed that older adults reported less negative affect (NA) compared with young adults. Older adults scored higher on agreeableness, conscientiousness, and social desirability, whereas young adults scored higher on extraversion and neuroticism. Based on correlational results, neuroticism was negatively correlated with extraversion, social desirability, and PA in older adults. Analyses of variance showed that conscientiousness, neuroticism, and social desirability impacted positive/negative affectivity. Conclusion: The results indicated that neuroticism proved to be the most important factor on emotional well-being. Older adults low on neuroticism experienced less NA. Furthermore, conscientiousness and social desirability had strong effects on PA indicating that the age-related differences found in affectivity might not only be attributable to age-related changes in personality, but also partly attributable to age-related increases in social desirability.
Are General Intelligence and Implicit Memory Related?: The Effect of Age
(2019) Kaynak, Hande
This study investigated the relationship between general intelligence and implicit memory performance in conjunction with aging. Data have been collected from 95 volunteers (49 young-46 older adults). General intelligence was measured by the Raven Standard Progressive Matrices (RSPM) test. Participants’ implicit memory performance was measured by the Word Stem Completion (WSC) task, in which the participants were presented with first three letters of a word and asked to complete this stem with the first word that comes to their mind. Explicit memory performance was also measured to be able to make a comparison with implicit memory performance and to document the differentiation between implicit and explicit memory. Although the same WSC task was used to measure implicit and explicit memory performance separately, the different instructions were used to deduce the different memory types. According to the results of factorial ANOVA, the main effect of age on general intelligence score was found to be statistically significant. After running further analyses by Pearson product-moment correlation coefficients, results indicated that RSPM test total correct score had a tendency to decrease with increasing age and RSPM test completion time had a tendency to increase with aging. Results also showed that implicit WSC task score and RSPM test total correct score were positively correlated. Similarly, explicit WSC task score and RSPM test total correct score were positively correlated, too. However, RSPM test completion time did not differ depending on implicit and explicit memory performances which were measured by WSC task. The present study indicated the relation between implicit WSC task and general intelligence. Within this context, this study is important to draw attention to the contribution of implicit memory measurement which is in the shadow of traditional explicit memory measurements to general intelligence, especially in older population.
Sleep spindle-related electroencephalograph activity of young adults and its relation to cognitive functions
(2019) Torun Yazıhan, Nakşidil; Yetkin, Sinan
Objective: Sleep spindles are phasic bursts of thalamocortical activity, typically defined as 11-16 Hz (in sigma frequency band) with a duration of 0.5 and 2 seconds. Spindles are most prominent during N2 sleep and are a defining feature of this stage. The aim of the present study was to investigate the association between spindle characteristics and cognitive functions of young adults. Methods:The study sample consisted of 17 healthy male subjects aged between 19 and 28 years.The participants had no medical or psychological conditions and were not taking any medications that might affect their sleep pattern and neuropsychological measurements. Polysomnography recordings were conducted from 22:30 to 07:00 hour for two subsequent nights. The first night was for adaptation to the laboratory conditions and to rule out sleep apnea syndrome and periodic leg movements. The second night was used to analyze macro and micro parameters of sleep. A neuropsychological test battery comprising the Serial Digit Learning Test, Raven Standard Progressive Matrices, Verbal Fluency Test,Trail Making A-B, and the Auditory Verbal Learning Test were administered before the second-night sleep session. Sleep spindles in all non-rapid eye movement stage 2 sleep were scored visually from C3-A2 electroencephalogram derivation after polysomnographic analysis was completed. Each 30-sec epoch was analyzed with a high-pass band filtered at 0.3 Hz, and a low-pass band filtered at 35 Hz. Spindle characteristics such as duration, amplitude, mean and peak frequencies were analyzed using the fast Fourier transform algorithm. The association between the characteristics of sleep spindles and the neuropsychological test scores were analyzed using Spearman correlations. Results: Significant positive correlations were found between spindle density and both verbal auditory learning performance and verbal fluency, cognitive flexibility, and semantic organization performances. The serial digit learning test was correlated positively with mean duration, mean frequency, and peak frequency of sleep spindles. Finally, the mean duration, and mean frequency of spindles were positively correlated with verbal fluency, cognitive flexibility, and semantic organization. Conclusion: The associations between spindle features and memory, verbal fluency, and verbal learning abilities were consistent with previous research findings suggesting that sleep spindles might be related to cognitive abilities and the potential to learn. In other words, it might be an indicator of the current level of aptitude for learning.

Relationships of Domestic Violence With Bullying, Silencing-The Resilience, and Self-Efficacy: Moderating Roles of Stress-Coping Strategies
(Springer, 2023) Karakus, Cansu; Goncu-Kose, Asli
The present study aimed to investigate the relationships of Child Exposure to Domestic Violence (CEDV) with bullying, silencing-the-self (STS) behaviors, resilience, and self-efficacy. In addition, moderating effects of stress-coping strategies in the relationships of CEDV with the outcome variables were examined. Data were collected from 569 adolescents aged between 14 and 17. The findings showed that CEDV was positively related to bullying and STS and it was negatively associated with resilience, overall self-efficacy, academic and emotional self-efficacy. Optimistic style and seeking social support moderated the relationship between CEDV and resilience. Also, the self-confident style, seeking social support, and optimistic style moderated the associations between CEDV and self-efficacy. Findings are discussed in terms of theoretical and practical contributions as well as directions for future research.
