Article Citation - WoS: 22Citation - Scopus: 24Antecedents of Problematic Social Media Use and Cyberbullying Among Adolescents: Attachment, the Dark Triad and Rejection Sensitivity(Springer, 2023) Demircioglu, Zeynep Isil; Goncu-Kose, AsliWith the acceleration of internet use, problematic social media use (PSMU) is included in our lives. When looking at the antecedents of PSMU, being young has been found to be a risk factor for PSMU. In addition to the benefits of technological advances in education and training, rapid technological developments may also result in problematic behaviors, especially among children and young. Recently, possibilities brought by technology and more widespread use of technology by young people have created a new concept, namely, cyberbullying. The present study aims to examine the effects of attachment anxiety and avoidance on PSMU and cyberbullying as with the partial mediating effects of the Dark Triad personality traits, angry rejection sensitivity, and anxious rejection sensitivity among adolescents. In general, the findings supported the proposed theoretical model. The results are discussed in terms of theoretical and practical implications along with suggestions for future research.Article Citation - WoS: 7Citation - Scopus: 7Locus of Control as a Mediator of the Relationships Between Motivational Systems and Trait Anxiety(Sage Publications inc, 2024) Turan, Aysu; Demir, Yagmur; Kaynak, HandeThe Reinforcement Sensitivity Theory, first proposed by Gray and later revised, describes three motivational systems: Behavioral Inhibition System (BIS), Behavioral Activation System (BAS), and Fight-Flight-Freeze System (FFFS). Studies have shown that high BIS and FFFS activation are positively related to anxiety symptoms, yet the relationship between BAS and anxiety remains unclear. Research data have also suggested that anxiety symptoms occur with the loss of perceived control. Thus, although studies on the direct effect of locus of control (LOC) on trait anxiety have accumulated for many years, the issue of how LOC may mediate the relationship between BIS/BAS/FFFS sensitivity and anxiety has not been addressed. This study aimed to explore the mediating role of LOC orientation on trait anxiety among young adults in association with these three motivational systems. Cross-sectional data were obtained from 422 volunteers. The BIS/BAS Scale, Trait Anxiety Inventory, and Rotter's Internal-External LOC Scale were applied. A series of mediation analyses were performed to estimate total, indirect, and direct effects. The results showed that BIS and FFFS positively predicted trait anxiety. In addition, LOC positively predicted trait anxiety and BIS. The results of the mediation analyses indicated that LOC functioned as a partial mediator between BIS and trait anxiety. This finding revealed that a high BIS level, one of the motivational systems, was associated with external LOC, which in turn contributed to reporting high trait anxiety in young adults. Hence, BIS and external LOC orientation could be suggested as risk factors for trait anxiety. As the external LOC orientation of individuals with high punishment sensitivity increased, their trait anxiety levels also increased. Therefore, it was suggested that it might be useful to be aware that LOC orientations of individuals with BIS sensitivity may pose a risk for trait anxiety.Article Citation - WoS: 13Citation - Scopus: 13Sleep, Sleep Spindles, and Cognitive Functions in Drug-Naive Patients With First-Episode Psychosis(Amer Acad Sleep Medicine, 2020) Yazihan, Naksidil Torun; Yetkin, SinanStudy Objectives: Various lines of clinical findings have suggested abnormalities in macro- or microstructural parameters of sleep in patients with schizophrenia. Meanwhile findings are inconclusive due to some confounding factors, such as the heterogeneity of the disorder, drug regimen, and duration of the illness. There are a few studies in the literature that have been conducted on drug-free patients with first-episode psychosis (FEP). Based on this knowledge, we aimed to explore sleep characteristics, sleep spindles, and neuropsychological profiles of the drug-naive patients with FEP. Methods: The study sample consisted of 21 drug-naive patients with FEP and 21 healthy participants. Polysomnography recordings were conducted for 2 subsequent nights. A neuropsychological test battery was administered for assessing cognitive functions. The Positive and Negative Syndrome Scale was applied to measure symptom severity of the patients. Spindle detection was performed visually. Results: According to the results of the study, the patient group's percentage of stage N2 sleep and sleep efficiency index was lower than in the control group. Among sleep spindle parameters, spindle density was found to be reduced in the patient group. The results of neuropsychological tests measuring executive functions, learning, and memory support the idea that there is a global cognitive deterioration from the early course of the disorder. In the psychotic group, negative symptoms were negatively correlated with verbal memory, learning, verbal fluency, and semantic organization. We found that the percentage of stage N3 sleep decreased while negative symptom severity increased. In addition, the percentage of stage N1 sleep increased as negative symptom severity increased. Reduction in stage N3 sleep was associated with an impairment in learning, verbal fluency, and response inhibition. The sleep spindle density and cognitive functions did not show any associations. Conclusions: Taken together, these findings suggest that patients with FEP show global cognitive impairment (except for attention and processing speed), which is associated with changes in sleep architecture and higher score in a scale assessing negative symptoms. We conclude that cognitive function and spindle parameters differ nonlinearly among patients with FEP.Article Citation - WoS: 16Citation - Scopus: 16Measuring 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, NilayThe 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.Article Citation - WoS: 7Citation - Scopus: 6Turkish Muslim Healers: a Qualitative Investigation of Hocas and Their Methods(Springer, 2020) Canel Cinarbas, Deniz; Tuna, Ezgi; Ar-Karci, YagmurA vast majority of Turkish individuals are Muslim, and several Turkish individuals refer to traditional healers to get help for medical and psychological problems. The purpose of the present study was to investigate Turkish traditional healing methods and to delineate the kinds of presenting problems that the clients bring to healers, methods used by the healers, the healing process, and the effect of healing on the clients. For this purpose, 11 participants were interviewed. The data were analyzed using the consensual qualitative research method. Nine domains emerged from the interviews: symptoms, diagnosis, etiology, treatment, response to treatment, characteristics of healers, clients' beliefs and desire to be healed, all healing coming from Allah (God), and characteristics of jinns. The findings were discussed in light of Kleinman's (Patients and healers in the context of culture: an exploration of the borderland between anthropology, medicine, and psychiatry, University of California Press, Berkeley,1980) illness explanatory model and characteristics of Turkish culture.Article Citation - WoS: 15Citation - Scopus: 15Psychometric Properties of the Turkish Version of the Behavioral Emotion Regulation Questionnaire (Berq)(Routledge Journals, Taylor & Francis Ltd, 2021) Tuna, EzgiThe Behavioral Emotion Regulation Questionnaire (BERQ) is a self-report measure of the behavioral strategies individuals use to regulate emotions in response to stressful or negative events. The purpose of the present study was to report on the psychometric properties of the Turkish version. The sample was recruited through courses at a semi-private university in Turkey and through social-media announcements. A sample of 320 adults (81.9% females, 18.1% males) with a mean age of 22.03 (SD = 2.73) completed the Turkish translation of the BERQ, the Emotion Regulation Questionnaire, the Difficulties in Emotion Regulation Questionnaire and the Brief Symptom Inventory. Exploratory factor analysis indicated that the Turkish version replicated the 5-factor structure of the original version; yet, a confirmatory factor analysis indicated that the original model showed an inadequate fit to the present data. Internal consistency coefficients of the subscales ranged between 0.72 and 0.88, and the test-retest reliability of subscales over a 3-week interval ranged from 0.51 to 0.70. As in the original version, we found that actively approaching and seeking social support were more adaptive strategies, whereas withdrawal and ignoring were less adaptive strategies. Results were mixed for the seeking distraction subscale. Additionally, withdrawal significantly predicted future depressive and anxiety symptoms. Overall, our results provide support for the Turkish version of the BERQ as a reliable and valid measure of behavioral emotion regulation strategies.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: 161Citation - Scopus: 156Measuring Anxiety Related To Covid-19: a Turkish Validation Study of the Coronavirus Anxiety Scale(Routledge Journals, Taylor & Francis Ltd, 2022) Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; Evren, CuneytThe aim of the current study is to validate the Turkish version of the Coronavirus Anxiety Scale (CAS). Participants were assessed across the CAS, Obsession with COVID-19 Scale (OCS) and Fear of COVID-19 Scale. We surveyed 1023 Turkish native speakers who participated online. Confirmatory factor analysis showed that the factor structure of the CAS was satisfactory. The scale was internally consistent with a Cronbach's alpha of 0.80. Positive correlations of the CAS with the OCS and the Fear of COVID-19 Scale demonstrated adequate convergent validity. These findings suggest that the CAS is a valid and reliable measure to assess the severity of dysfunctional coronavirus related anxiety.Article Citation - WoS: 32Citation - Scopus: 36Attentional Control Is Partially Impaired in Obstructive Sleep Apnea Syndrome(Wiley, 2013) Atalay, Nart Bedin; Kanat, Fikret; Suerdem, Mecit; Tulek, BaykalObstructive sleep apnea syndrome is associated with executive cognitive impairment. An important question is whether impairment in executive functioning in obstructive sleep apnea syndrome is independent of dysfunction in attention. Attentional control is a subcomponent of executive functioning that is mediated by frontal lobe processing. In the current study, we investigated whether attentional control is deficient in obstructive sleep apnea syndrome. Attentional control processes were investigated through conflict adaptation and conflict frequency paradigms. These neuropsychological paradigms were assessed by using the Simon, Flanker and Stroop tasks. We additionally analysed post-error slowing data within these tasks. Error processing is another index of cognitive control that is mediated by frontal lobe functioning. Our sample consisted of 14 healthy adults and 24 patients with untreated moderate-severe obstructive sleep apnea syndrome. Results indicated that attentional control is partially dysfunctional among patients with obstructive sleep apnea syndrome. Attentional control processes were deficient when focal attention (Flanker task) processes were involved, but were intact when observed using the Simon and Stroop tasks. A non-significant trend in post-error slowing data suggested that error processing, assessed with the Flanker task, was diminished among patients with obstructive sleep apnea syndrome. These results support the view that obstructive sleep apnea syndrome leads to some amount of frontal lobe dysfunction, and that attentional control and error processing might be particularly affected by obstructive sleep apnea syndrome.Article 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.
