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: 2Citation - Scopus: 3The 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, HandeObjective: 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."Article 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, AsliWith 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.Article Citation - WoS: 1Citation - Scopus: 1Direct 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, HandeObjective: 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.Article 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.

Methods: The cross-sectional online study was conducted with 752 volun-teer participants in Turkey. The participants were assessed with the nine-item Internet Gaming Disorder Scale - Short Form (IGDS9-SF) and the Motives for Online Gaming Questionnaire (MOGQ). Results: The age of participants who engage with loot boxes (n=171, 22.7%) was lower than the group who do not engage with loot boxes (n=581, 77.3%). Also, of the male using microtransaction, buying games, time spent on the gaming, gaming more than usual on weekends, being an e-sport gamer and/or following e-sport, having problems related with gaming, using MMORPGs, the severity of IGD symptoms, and all six types of motives for online gaming were higher in the group who engage with loot boxes. Age at first gaming did not differ between the groups. In the logistic regression model, loot box engagement was related to the severity of disordered gaming, using MMORPGs and severities of skill development and competition motives for online gaming. Conclusion: These findings suggest that those who engage with loot boxes may be using MMORPGs more with the motives of skill development and competition and they may have higher severity of IGD symptoms. Thus, this group of gamers who engage with loot boxes should be considered as a risk group and interventions should particularly include these individuals.Article Citation - WoS: 4Citation - Scopus: 5The Relationship Between Probable Adhd and Playing Mmorpgs With the Severity of Disordered Gaming: The Effect of Gaming Motivations(Kare Publ, 2021) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Topcu-bulut, MerveObjective: The main aim of the present study was to consider the impact of gaming motivations among young adults when evaluating the relationship between probable attention deficit hyperactivity disorder (ADHD) and massively multiplayer online role-playing games (MMORPGs), with disordered gaming. Method: In the present study, participants were assessed with the Adult ADHD Self-Report Scales (ASRS-v1.1), the Motives for Online Gaming Questionnaire (MOGQ), and the nine-item Internet Gaming Disorder Scale-Short Form (IGDS9-SF). Results: Participants with probable ADHD (n=143,19.2%) and without probable ADHD (n=602, 80.8%) did not differ according to the current age, gender, presence of romantic relationship, marital status, where and with whom they are living, employment status and time spent on the gaming. Compared to participants without probable ADHD, those with probable ADHD had higher rates of having a game console, purchasing games, gaming more than usual on weekends, having problems related to gaming, probable internet gaming disorder (IGD) according to IGDS9-SF cut-off score and higher scales scores (IGDS9-SF and MOGQ), whereas they had a lower age at first gaming. Among different game types, those with probable ADHD were gaming more with multiplayer online battle arena games, social network games, music games, MMORPGs, sports games/car games, and horror-themed/survival games. Scores of all six types of gaming motives were higher among those with probable ADHD, and among them coping/escape, social, skill development, and fantasy distinguished the presence of probable ADHD. In the ANCOVA analysis, the presence of probable ADHD and the use of MMORPGs (as well as online gaming motives [coping/escape, recreation, fantasy, social and competition]) predicted the severity of IGD symptoms, and also these effects also interacted, involving probable ADHD and using MMORPGs. Conclusion:These findings suggest that those with probable ADHD may have different gaming characteristics than those without probable ADHD. Probable ADHD and using MMORPGs are related to the severity of disordered gaming, along with almost all type of online gaming motivations. Also, the effects of probable ADHD and MMORPGs use interacted with each other.Article Remembered or Forgotten Stimuli: a Functional Magnetic Resonance Imaging Study on the Effects of Emotion(Kare Publ, 2020) Kilic, Betul; Ozcelik, ErolObjective: The first aim of this study is to examine why emotional events enhance memory for preceding stimuli. The second goal is to identify brain regions associated with remembering and forgetting by finding brain activation differences during encoding of remembered and forgotten stimuli. The third goal is to examine which brain areas are activated when studying emotional pictures compared to neutral ones. Method: In each trial, a picture of an object followed by an emotional or neutral picture from the Turkish culture were presented to 15 volunteers. The effect of the succeeding pictures on the remembering of preceding stimuli was examined. The participants studied the stimuli in the magnetic resonance scanner and, meanwhile, brain images were taken. The memory performances of the participants were measured with the recognition test administered one week later. Results: Behavioral results suggest that emotion has no effect on memory for preceding stimuli. Functional magnetic resonance imaging results indicate that remembered stimuli compared to forgotten ones caused more activation in left inferior frontal gyrus and left superior medial gyrus. Emotional pictures create more activation in the - mid-temporal gyrus and supramarginal gyrus compared to neutral images. Conclusion: Brain structures in which activations are observed in remembered stimuli compared to forgotten ones (left inferior frontal gyrus and left superior medial gyrus) are responsible for the semantic elaboration and associative memory formation. Thus, it can be concluded that object pictures are remembered because they are processed more deeply. Besides, activations are observed in the areas known to be related to the processing of emotional face expressions when emotional and neutral pictures are compared.Article 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, HandeAlzheimer'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.Article Does a correlation exist between fluid intelligence and creativity?(2020) Torun Yazıhan, NakşidilThe aim of the study was to investigate the associations between fluid intelligence and creativity among young adults.
