Case Report: Physiological and Psychological Underpinnings of Muscle Dysmorphia Using EEG, GSR, and Eye-Tracking
(Frontiers Media SA, 2025) Cinaroglu, Metin; Ulker, Selami Varol; Yilmazer, Eda; Sayar, Goekben Hizli
Background Muscle dysmorphia (MD), a subtype of Body Dysmorphic Disorder (BDD), involves an obsessive preoccupation with perceived insufficient muscularity despite an objectively muscular physique. While its psychological features are well-documented, physiological and attentional underpinnings remain underexplored.Objective This exploratory, proof-of-concept case series examines the psychological, physiological, and attentional characteristics of individuals with varying experiences of MD using a multimodal approach combining electroencephalography (EEG), galvanic skin response (GSR), and eye-tracking technologies.Methods Three male participants were purposefully selected to represent distinct clinical profiles: one with active MD and steroid use, one in sustained remission from MD, and one with no MD history. Participants completed validated psychological scales (MDDI, BIDQ, STAI, RSES) and were exposed to personalized visual stimuli (past, current, and idealized body images). A triangulated recording protocol was used to capture EEG, GSR, and eye-tracking data during stimulus exposure.Results Participants with current and past MD showed elevated beta wave activity, increased skin conductance, and attentional biases toward muscular regions, corresponding with higher self-reported distress and anxiety. In contrast, the control participant exhibited stable physiological responses and emotionally neutral reactions. Triangulated data revealed coherent patterns across subjective and physiological domains, supporting the internal validity of the findings despite the small sample.Conclusion These findings illustrate the potential of multimodal assessment in identifying candidate psychophysiological markers of MD. While not generalizable, this case-series provides a valuable framework for future hypothesis-driven research and supports the need for gender-specific diagnostic and intervention strategies in muscle dysmorphia.
Cognitive Behavioral Therapy for Muscle Dysmorphia and Anabolic Steroid-Related Psychopathology: A Randomized Controlled Trial
(MDPI, 2025) Cinaroglu, Metin; Yilmazer, Eda; Ulker, Selami Varol; Sayar, Gokben Hizli
Background/Objectives: Muscle dysmorphia (MD), a subtype of body dysmorphic disorder, is prevalent among males who engage in the non-medical use of anabolic-androgenic steroids (AASs) and performance-enhancing drugs (PEDs). These individuals often experience severe psychopathology, including mood instability, compulsivity, and a distorted body image. Despite its clinical severity, no randomized controlled trials (RCTs) have evaluated structured psychological treatments in this subgroup. This study aimed to assess the efficacy of a manualized cognitive behavioral therapy (CBT) protocol in reducing MD symptoms and associated psychological distress among male steroid users. Results: Participants in the CBT group showed significant reductions in MD symptoms from the baseline to post-treatment (MDDI: p < 0.001, d = 1.12), with gains sustained at follow-up. Large effect sizes were also observed in secondary outcomes including depressive symptoms (PHQ-9: d = 0.98), psychological distress (K10: d = 0.93), disordered eating (EDE-Q: d = 0.74), and exercise addiction (EAI: d = 1.07). No significant changes were observed in the control group. Significant group x time interactions were found for all outcomes (all p < 0.01), indicating CBT's specific efficacy. Discussion: This study provides the first RCT evidence that CBT significantly reduces both core MD symptoms and steroid-related psychopathology in men engaged in AAS/PED misuse. Improvements extended to mood, body image perception, and compulsive exercise behaviors. These findings support CBT's transdiagnostic applicability in addressing both the cognitive-behavioral and affective dimensions of MD. Materials and Methods: In this parallel-group, open-label RCT, 59 male gym-goers with DSM-5-TR diagnoses of MD and a history of AAS/PED use were randomized to either a 12-week CBT intervention (n = 30) or a waitlist control group (n = 29). CBT sessions were delivered weekly online and targeted distorted muscularity beliefs, compulsive behaviors, and emotional dysregulation. Primary and secondary outcomes-Muscle Dysmorphic Disorder Inventory (MDDI), PHQ-9, K10, EDE-Q, EAI, and BIG-were assessed at the baseline, post-treatment, and 3-month follow-up. A repeated-measures ANOVA and paired t-tests were used to analyze time x group interactions. Conclusions: CBT offers an effective, scalable intervention for individuals with muscle dysmorphia complicated by anabolic steroid use. It promotes broad psychological improvement and may serve as a first-line treatment option in high-risk male fitness populations. Future studies should examine long-term outcomes and investigate implementation in diverse clinical and cultural contexts.
Effects of Mindfulness on Test Anxiety: A Meta-Analysis
(Frontiers Media Sa, 2024) Yilmazer, Eda; Hamamci, Zeynep; Turk, Fulya
Objective: This meta-analysis evaluated the effectiveness of mindfulness-based interventions (MBIs) on test anxiety across diverse age groups and intervention modalities. Methods: Rigorous inclusion criteria were applied to select studies focusing on MBIs as the independent variable, with test anxiety as the outcome. A comprehensive search across multiple databases yielded 18 primary studies, contributing 20 comparisons. Data were extracted on study characteristics, sample sizes, and intervention details, and were analyzed using a random-effects model. Results: The analyses incorporated 1,275 participants, with MBIs demonstrating a moderate to large negative effect on test anxiety (effect size = -0.716; 95% CI: -1.383 to -0.049). Moderation analysis indicated that mean age, number of sessions, and intervention delivery mode did not significantly influence effect sizes. Publication bias assessment suggested the presence of bias via Egger's regression (p = 0.025), though Begg and Mazumdar's test and Duval and Tweedie's trim and fill method indicated no missing studies. Conclusion: MBIs are effective in reducing test anxiety, though results should be interpreted with caution due to potential publication bias and unexplained heterogeneity. The impact of MBIs did not vary significantly with participant age, number of sessions, or delivery mode.
Ethical Leadership and Perceived Organizational Fairness: A Moderated Mediation Model of Moral Identity and Psychological Contract Breach
(Routledge Journals, Taylor & Francis Ltd, 2025) Aktas, Burak Nedim; Gunalan, Mustafa; Akcin, Kultigin; Erat, Serhat
This study identifies when and how ethical leadership is linked to employees' perceptions of organizational fairness. We propose and test a mechanism in which followers' moral identity explains this link, and the state of the psychological contract sets its boundaries, highlighting a novel, process-focused view of fairness formation. Using a cross-sectional survey of 306 white-collar employees in T & uuml;rkiye's industrial sector, we estimated a moderated-mediation model with partial least squares structural equation modeling and bootstrap inference. Results revealed that ethical leadership related to perceived organizational fairness indirectly through the symbolization (outward expression) facet of moral identity, whereas internalization (inward conviction) was unrelated. This indirect link emerged only when employees perceived that promised obligations were honored, indicating that psychological-contract fulfillment enables ethical signals to be read as fair. The findings clarify that visible moral behavior matters more than inward conviction for fairness judgments and that relational integrity is a precondition for leader influence. We discuss implications for theory and for building fair climates by making ethics visible and keeping promises.
Investment Strategies for Renewable Energy Technologies and Harvesting Systems in Airport Operations Using Spherical Fuzzy MCDM Models
(Nature Portfolio, 2025) Mizrak, Filiz; Sahin, Didem Rodoplu
This study presents a novel evaluation framework for prioritizing investment strategies in sustainable airport energy systems by integrating advanced fuzzy decision-making techniques with artificial intelligence-based expert weighting. Specifically, it employs a hybrid Spherical Fuzzy CRITIC-RATGOS model to rank renewable energy alternatives based on economic feasibility, environmental impact, technological efficiency, scalability, and operational reliability. To address limitations associated with equal expert weighting, a Principal Component Analysis-driven dimension reduction technique is applied to calibrate expert influence based on professional background and consistency of evaluation. The model is applied to a real-world case study at Istanbul Airport, demonstrating that AI-optimized energy management, solar microgrids, and waste-to-energy conversion are the most promising investment alternatives. In contrast, although technologies such as piezoelectric harvesting show future potential, their current limitations reduce their immediate feasibility. Sensitivity analysis affirms the robustness and stability of the results across various weighting configurations. The proposed framework contributes to both theory and practice by offering a scalable, transparent, and replicable decision-support tool for airport authorities, policymakers, and energy planners aiming to align infrastructure development with global sustainability and decarbonization goals.
Job Demands, Resources, and Future Considerations: Academics' Experiences of Working from Home During the Coronavirus Disease 2019 (COVID-19) Pandemic
(Frontiers Media Sa, 2022) Karatuna, Isil; Joensson, Sandra; Muhonen, Tuija
The coronavirus disease 2019 pandemic has severely affected workers, workplaces, and working practices. In the higher education setting, universities have shifted to distance learning, resulting in profound changes in academics' work. In this study, we aimed to describe academics' job demands and resources related to changes in working conditions during the pandemic, and to examine how these changes have affected the perceived occupational wellbeing of academics. Additionally, we aimed to investigate academics' expectations and concerns for future academic working practices following the pandemic. The data were collected through semi-structured interviews with 26 academics working at various universities in Sweden. A content analysis was used to identify the key themes from the transcribed interviews. The results indicated that academics experienced a lack of face-to-face communication, absence of an academic environment, work overload, and work-home interference as demanding during the pandemic. In relation to resources, online communication options, appropriate working conditions, organizational-social support, and individual factors were perceived as important. Most respondents perceived negative occupational wellbeing outcomes. However, academics who had the appropriate resources were less likely to be affected by job demands. Academics' expectations for future academic work included continuation of working online, flexibility in the choice of workspace, and strengthened digital capacity. Their concerns were related to a lack of face-to-face interaction, management actions and economic implications, and pure digital education. This paper contributes to the literature by illustrating the complexity and diversity of experiences and preferences among academics that are important for universities to consider when organizing and managing future academic work.
The Mediating Role of Cognitive Emotion Regulation Skills in the Relationship Between Romantic Relationship Satisfaction and Eating Attitudes
(Springer Nature, 2025) Yilmazer, Eda; Turk, Fulya; Hamamci, Zeynep
Background Romantic relationship satisfaction has been linked to psychological outcomes, including emotional well-being and eating behaviors. However, the mechanisms underlying this relationship remain unclear. This study examines the mediating role of cognitive emotion regulation strategies-particularly catastrophizing-in the relationship between romantic relationship satisfaction and eating attitudes. Methods A cross-sectional study was conducted with 355 university students. Participants completed the Relationship Satisfaction Scale, the Cognitive Emotion Regulation Questionnaire (CERQ), and the Eating Attitudes Test-26 (EAT-26). Structural equation modeling (SEM) was performed using AMOS and R with robust maximum likelihood estimation. Model fit was evaluated using chi 2/df, CFI, GFI, RMSEA, and SRMR. Results Catastrophizing significantly mediated the relationship between romantic relationship satisfaction and eating attitudes. Romantic relationship satisfaction was negatively associated with catastrophizing (beta = -0.18, p = .028), and catastrophizing was positively associated with problematic eating attitudes (beta = 0.35, p < .001). The direct effect of romantic relationship satisfaction on eating attitudes was not statistically significant (beta = -0.12, p = .104), indicating full mediation. Acceptance did not significantly mediate the relationship (p = .348). Gender differences were observed: women scored significantly higher on rumination, dieting, and bulimia/food preoccupation (p < .05). Conclusions These findings highlight the role of maladaptive cognitive emotion regulation-specifically catastrophizing-in linking romantic relationship dissatisfaction with disordered eating attitudes. Targeting catastrophizing in interventions may improve both relationship satisfaction and eating behaviors.
Mediating Role of Psychological Maladjustment in Relation Between Dark Triad, Psychological Distress and Subjective Happiness of Pakistani Emerging Adults
(Frontiers Media Sa, 2022) Mushtaq, Asia; Inam, Ayesha; Najmussaqib, Arooj; Afshan, Anjum; Ermagan-Caglar, Eda
The transition from adolescence to adulthood is fraught with challenges that might have impacts on later life and personality development. Earlier research investigated Dark Triad traits in connection to emotional problems. The current study, on the other hand, focused on investigating the mediating role of psychological maladjustment in the relation of Dark Triad traits, psychological distress, and subjective happiness in emerging adults. A sample of 546 participants aged 18-25 years (M = 21.2 years) from Pakistan have participated to complete an online survey. Standardized assessment tools were used to measure the targeted variables. Results indicated that Machiavellianism and psychopathy were positively associated with psychological distress, whereas narcissism appeared to be a non-significant predictor. Subjective happiness was positively associated with Machiavellianism and negatively associated with psychopathy. In addition, mediation analysis through Structural Equation Modeling (SEM) indicated that the Dark Triad traits (Machiavellianism and psychopathology), psychological distress, and subjective wellbeing were explained by psychological maladjustment. Implications and limitations are discussed.
Menstrual Cycle-Related Changes in Women with Schizophrenia: A Resting-State fMRI Study
(Karger, 2022) Noyan, Handan; Hamamci, Andac; Firat, Zeynep; Sarsilmaz, Aysegul; Ucok, Alp
Introduction: Different influences of ovarian hormones in schizophrenia (SCZ) have been reported, but no study to date has assessed their effects on the brain dynamics at rest. The present study aimed to examine the hormonal and clinical changes related to the menstrual cycle and alterations in the resting-state functional connectivity (RS-FC) depending on cycle phase and/or hormonal fluctuations in SCZ. Method: This study was conducted based on both between- and within-subject experimental designs, including 13 clinically stable female patients with SCZ (32 +/- 7.7 years) and 13 healthy women (30 +/- 7.3 years). RS-functional magnetic resonance imaging (fMRI) scanning, as well as hormonal and clinical assessments, was applied to each participant twice during two cycle phases: early follicular and mid-luteal. Results: A difference in mid-luteal progesterone levels was found between groups, with a large effect size (Cohen's d) of 0.8 (p < 0.05). Also, the estradiol levels negatively correlated with the negative symptom severity of the patients during their mid-luteal phase. In the patients, estrogen positively correlated with the auditory network connectivity in the left amygdala during the early follicular phase. In the controls, progesterone had positive correlations with the connectivity of the posterior default mode and the left frontoparietal networks in the bilateral precuneus during the early follicular phase and had a negative correlation with the executive control network connectivity in the mid-luteal phase. Conclusion: The present study showed hormonal differences between groups and suggested that the levels of cycle-dependent hormones might be associated with the changes in clinical symptom severity and the RS-FC in the groups. Our RS-fMRI findings warrant further investigation.
Prioritizing Cybersecurity Initiatives in Aviation: A DEMATEL-QSFs Methodology
(Cell Press, 2024) Mizrak, Filiz; Akkartal, Gonca Reyhan
The aviation industry's growing dependence on digital technologies necessitates robust cybersecurity measures to counter advanced threats. This study integrates the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method with Quantum Spherical Fuzzy Sets (QSFS) to enable precise and reliable decision-making under uncertainty. Key criteria, identified through expert evaluations, include Threat Detection Systems (TDS), Data Encryption Protocols (DEP), Regulatory Compliance (RC), Incident Response Plans (IRP), User Training (UT), Access Control Mechanisms (ACM), and Network Security Solutions (NSS). Analysis using the proposed method revealed that "Regulatory Compliance" and "Threat Detection Systems" are the most influential factors, emphasizing the need for strict adherence to standards and advanced threat detection capabilities. Additionally, the significance of "User Training" and "Data Encryption Protocols" underscores the importance of comprehensive training programs and strong encryption measures. By incorporating strategic management theories such as the Resource-Based View (RBV), Contingency Theory, and Risk Management Theory, this study presents a strategic framework to assist aviation organizations, policymakers, and researchers in developing effective cybersecurity strategies, ensuring the safety and security of global air travel.
Problematic Social Media Use, Self-Objectification, and Body Image Disturbance: The Moderating Roles of Physical Activity and Diet Intensity
(Dove Medical Press Ltd, 2025) Cinaroglu, Metin; Yilmazer, Eda
Purpose: This study examines the relationship between problematic social media use, self-objectification, and body image disturbance in women, with physical activity and diet intensity as moderators. It also explores the psychological outcomes of depression and anxiety.
Methods: A cross-sectional study was conducted with 594 women aged 18- 65 in Istanbul, T & uuml;rkiye. Participants completed validated measures assessing social media use, self-objectification, body image disturbance, physical activity, diet intensity, depression, and anxiety. A moderated mediation analysis was performed.
Results: Self-objectification significantly mediated the relationship between problematic social media use and body image disturbance (b = 0.14, SE = 0.03, 95% CI [0.10, 0.21], p < 0.01, R-2 = 0.18). Physical activity buffered this effect (b = - 0.12, SE = 0.05, p = 0.02, d = 0.36), while diet intensity exacerbated it (b = 0.15, SE = 0.04, p < 0.01, d = 0.42). Body image disturbance also mediated the association between social media use and depression (b = 0.18, SE = 0.05, p < 0.01, R-2 = 0.22) and anxiety (b = 0.16, SE = 0.04, p < 0.01, R-2 = 0.19).
Conclusion: The findings highlight the dual roles of physical activity and diet intensity in shaping body image outcomes. The study underscores the need for targeted interventions to mitigate the negative impact of social media-driven self-objectification on body image and mental health.
Psychological Distress, Resilience, and Well-Being Among Survivors of the 2023 Kahramanmaraş Earthquakes: A Multi-Site Cross-Sectional Study
(Frontiers Media SA, 2025) Yilmazer, Eda
Background The 2023 Kahramanmara & scedil; earthquakes were among the most devastating disasters in modern T & uuml;rkiye, with severe consequences for survivors' mental health. While post-disaster psychopathology has been widely studied, less is known about positive psychological outcomes such as resilience and well-being in this context.Objective This study examined levels of depression, anxiety, post-traumatic stress symptoms, well-being, and resilience among earthquake survivors, explored group differences, and identified predictors of key psychological outcomes.Methods A cross-sectional survey was conducted with 642 adult survivors across 11 heavily affected cities, nearly 2 years after the earthquakes. Data were collected between September 2024 and January 2025, corresponding to 19-22 months after the earthquakes. Participants completed validated self-report measures: BDI-II, BAI, PCL-5, WEMWBS, and CD-RISC. Analyses included group comparisons, correlations, hierarchical regressions predicting well-being and resilience, and logistic regression predicting probable PTSD (PCL-5 >= 47).Results Survivors reported moderate depression (M = 22.1), mild-moderate anxiety (M = 19.4), and near-threshold PTSD symptoms (M = 40.0). Overall, 31.0% of participants exceeded the PCL-5 cut-off for probable PTSD (95% CI: 27.4-34.8%). Well-being (M = 35.6) and resilience (M = 56.0) were below normative values. Women reported higher depression than men, while trauma-exposed participants had significantly worse outcomes across all measures. Bivariate correlations showed strong associations between distress, reduced well-being, and diminished resilience. Hierarchical regressions indicated that depression and PTSD symptoms were the primary predictors of both lower well-being (R2 = 0.45) and resilience (R2 = 0.32). Logistic regression revealed that female gender (OR = 1.80, p = 0.024) and depression severity (OR = 1.10, p = 0.001) significantly increased the likelihood of probable PTSD.Conclusion Nearly 2 years after the earthquakes, survivors experienced substantial psychological distress alongside reduced well-being and resilience. Clinical symptoms, particularly depression and PTSD, more strongly associated with outcomes than sociodemographic or exposure variables. These findings highlight the need for interventions that both alleviate trauma-related psychopathology and strengthen resilience and well-being as part of long-term disaster recovery.
Psychological Impact of the 2023 Kahramanmaras Earthquakes on Non-Victims: A Cross-Sectional Study
(BMC, 2025) Cinaroglu, Metin; Yilmazer, Eda; Sayar, Gokben Hizli
The 2023 Kahramanmara & scedil; earthquakes, with magnitudes of 7.7 and 7.6, caused extensive destruction and psychological distress across southeastern Turkey. This study explores the psychological impact on non-victims, particularly Istanbul residents, focusing on mental health outcomes and coping mechanisms. A cross-sectional survey was conducted from March to May 2024 with 721 participants from various Turkish cities, including a significant portion from Istanbul. Validated psychological scales such as the Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Warwick-Edinburgh Mental Well-being Scale (WEMWBS), and PTSD Checklist for DSM-5 (PCL-5) measured depression, anxiety, well-being, and PTSD symptoms. Sociodemographic factors like age, gender, occupation, income, education level, and previous earthquake experience were also analyzed. Results showed significant psychological distress among non-victims: 51.9% reported high levels of distress, with 24% meeting PTSD criteria, 30% exhibiting moderate to severe depression, and 28% experiencing significant anxiety. Higher income and education levels correlated with better mental health outcomes. Higher education levels were linked to lower PTSD risk (beta = -0.20, p < 0.01) and fewer depression symptoms (beta = -0.15, p < 0.05). Higher income was associated with lower depression scores (beta = -0.20, p < 0.01) and fewer PTSD symptoms (beta = -0.15, p < 0.05). Age positively correlated with well-being (r = 0.68, p < 0.001) and negatively with PTSD symptoms (r = -0.15, p < 0.05). Comparisons with victim studies of major earthquakes, such as the 1995 Great Hanshin-Awaji earthquake, the 1999 Marmara earthquake, the 2008 Wenchuan earthquake, and the 2000 Iceland earthquakes, revealed similar profound psychological impacts. This highlights the need for comprehensive mental health interventions for both direct and indirect exposures. This study underscores the necessity for inclusive mental health strategies to enhance resilience and well-being, ensuring robust recovery after catastrophic events.
Psychological Impact of the 2023 Kahramanmaraş Earthquakes: A Systematic Review and Meta-Analysis of PTSD, Depression, and Anxiety Among Turkish Adults
(Frontiers Media SA, 2025) Cinaroglu, Metin; Yilmazer, Eda; Ahlatcioglu, Esra Noyan; Ulker, Selami Varol; Sayar, Gokben Hizli
Background The twin earthquakes that struck Kahramanmara & scedil;, T & uuml;rkiye, on February 6, 2023, caused widespread devastation and loss of life. Beyond the physical destruction, such large-scale disasters often result in significant psychological trauma. This study systematically reviewed and meta-analyzed the prevalence and severity of probable post-traumatic stress disorder (PTSD), depression, and anxiety among adult Turkish survivors during the first 18 months post-disaster. Methods Following PRISMA 2020 guidelines, a systematic search of Web of Science, PubMed, and Scopus was conducted for peer-reviewed studies published between February 6, 2023, and May 30, 2025. Eligible studies included quantitative assessments of PTSD, depression, or anxiety using validated Turkish-language scales, with general adult population samples (N >= 370). Eight studies (N = 5,965) met inclusion criteria. A random-effects meta-analysis was conducted for studies reporting prevalence of probable PTSD, while depression and anxiety outcomes were synthesized descriptively due to limited and heterogeneous data. Risk factors for psychological morbidity were also extracted and analyzed. This review was registered with PROSPERO (CRD42025644127). Results The pooled prevalence of probable PTSD was 41% (95% CI: 32-52%). Reported PTSD rates ranged from 29 to 54%, and symptom severity remained high throughout the first year. Depression and anxiety were also widespread, with up to 40% screening positive for depression and 40-50% reporting moderate-to-severe anxiety symptoms. Comorbidity between PTSD, depression, and anxiety was common. Significant risk factors included female gender, bereavement, home destruction, displacement, job loss, and low social support. Resilience was protective in some studies, though findings were inconsistent. Conclusion Eighteen months after the 2023 Kahramanmara & scedil; earthquakes, Turkish adult survivors continued to experience high levels of probable PTSD, depression, and anxiety. These findings highlight a prolonged mental health crisis and underscore the urgent need for sustained, targeted psychosocial interventions. Integrating mental health support into disaster preparedness and long-term recovery efforts is essential for mitigating psychiatric morbidity in future disasters.Systematic review registration https://www.crd.york.ac.uk/PROSPERO/view/CRD42025644127.
Psychometric Properties and Validation of the Metacognitive Self-Assessment Scale (MSAS) in a Turkish Sample
(Frontiers Media Sa, 2024) Yilmazer, Eda; Hamamci, Zeynep; Tuerk, Fulya
Objective: Metacognition, a multifaceted psychological construct, encompasses recognising and explaining one's cognitive processes and those of others. Notably, deficits in metacognitive abilities are linked with diminished social performance, reduced quality of life, and increased severity of Personality Disorders (PD). While there are other assessment tools available in Turkish for evaluating metacognition, none offer the same combination of speed, simplicity, flexibility, and multidimensionality for screening metacognitive abilities as the Metacognition Self-Assessment Scale (MSAS).The Metacognitive Self-Assessment Scale (MSAS) was designed to evaluate various metacognitive functions-namely, Monitoring, Integration, Differentiation, and Disintegration-as described by the Metacognitive Multifunction Model. This study aims to translate and validate the MSAS for Turkish culture. Method: To check the factor structure's suitability for the Turkish population, 467 non-clinical participants (67.7% female, ranged from 18 to 31, mean 24.18; 3.25) were included. Results: Initial analyses confirm that the scale is a valid and dependable instrument for Turkish culture. Construct validity, represented by the 18 items and four subscales, was confirmed through Confirmatory Factor Analysis (CFA) and criterion validity assessments. As well as the test-retest reliability of the scale was confirmed. Based on these findings, it was concluded that the scale is valid and reliable for use in Turkey. The model aligns well with empirical data, highlighting its strong construct validity and indicating good reliability of the scale. Conclusion: The Turkish version of the MSAS, developed to measure metacognition and its associated components, has proven to be a credible and reliable tool, especially in non-clinical settings.
The Relationship Between Childhood Trauma, Psychotic Symptoms, and Cognitive Schemas in Patients with Schizophrenia, Their Siblings, and Healthy Controls: Results from the Eu-Gei Study
(Cambridge University Press, 2024) Ucok, Alp; Noyan, Handan; Guloksuz, Sinan; Saka, Meram Can; Alptekin, Koksal; Atbasoglu, Cem; van Os, Jim
Background The relationship between childhood trauma (CT) and psychotic symptoms in patients with schizophrenia (SCZ), and subthreshold psychotic experiences in non-clinical populations is well-established. However, little is known about the relationship between subtypes of trauma and specific symptoms in patients, their siblings, and controls. It is also not clear which variables mediate the relationship between trauma and psychotic symptoms.Methods Seven hundred and forty-two patients with SCZ, 718 of their unaffected siblings and 1039 controls from three EU-GEI sites were assessed for CT, symptom severity, and cognitive schemas about self/others. CT was assessed with the Childhood Trauma Questionnaire, and cognitive schemas were assessed by The Brief Core Schema Scale.Results Patients with psychosis were affected by CT more than their siblings and controls in all domains. Childhood emotional abuse and neglect were more common in siblings than controls. CT was related to negative cognitive schemas toward self/others in patients, siblings, and controls. We found that negative schemas about self-mediated the relationship between emotional abuse and thought withdrawal and thought broadcasting. Approximately 33.9% of the variance in these symptoms was explained by the mediator. It also mediated the relationship between sexual abuse and persecutory delusions in SCZ.Conclusions Our findings suggest that childhood abuse and neglect are more common in patients with schizophrenia than their siblings and healthy controls, and have different impacts on clinical domains which we searched. The relationship between CT and positive symptoms seems to be mediated by negative cognitive schemas about self in schizophrenia.
School-Based Psychosocial and Educational Interventions for Children and Adolescents After the 1999 Marmara Earthquakes in Turkey: A Review on Lessons Learned
(Pergamon-Elsevier Science Ltd, 2024) Cihanoglu, Mine; Vatansever, Merve; Erden, Gulsen
The massive earthquakes experienced in August and November 1999 affected thousands of people in the Marmara region, the most densely populated and industrialized part of Turkey. The humanitarian and economic cost was so enormous, and these earthquakes have changed the Turkish disaster management system and the Turkish people's approach to disasters. Marmara earthquakes are also considered as a milestone in the provision of psychosocial services for disaster victims. This paper aims to review the psychosocial interventions targeting children, adolescents, and their families after the 1999 earthquakes in Turkey. The progression from initial responses to more organized psychosocial interventions is outlined. Conducting the interventions at schools has ensured that thousands of children, teachers, and parents are reached in the most efficient and effective way possible. The significance of the school context in designing psychosocial interventions is highlighted and implications of the lessons learned for traumatic experiences of children and parents are also explored. It is evaluated that these inferences obtained from the Marmara earthquake in Turkey can be used in disasters around the world.
Unique Challenges in the Turkish Workforce: Examining the Impact of Job Demands and Resources on Work-Related Outcomes of Blue- and White-Collar Workers
(Frontiers Media SA, 2025) Ilhan, Umit Deniz; Guler, Burcu Kumbul; Turgut, Dilara; Duran, Cem
Introduction An increasing body of research has explored the impact of job demands and resources on employee wellbeing and performance; however, empirical evidence remains limited regarding how these factors operate in non-Western contexts. Addressing this gap, the present study examines blue-collar (70.7%) and white-collar (29.3%) workers in T & uuml;rkiye, investigating the effects of job demands (quantitative, cognitive, emotional) and job resources (leader support, co-worker support, trust) on emotional exhaustion, job satisfaction, organizational commitment, and intention to leave.Method A total of 563 employees from three large production companies in T & uuml;rkiye voluntarily participated in this study. Data were collected using the Turkish version of the Copenhagen Psychosocial Questionnaire (COPSOQ-III) for all constructs, except for intention to leave, which was assessed using the Michigan Organizational Assessment Questionnaire (MOAQ). The proposed relationships were analyzed through multi-group structural equation modeling (MG-SEM).Results Job demands significantly increased emotional exhaustion in both blue- and white-collar workers. However, while emotional exhaustion did not diminish organizational commitment among blue-collar workers, job satisfaction emerged as a key determinant in reducing their turnover intentions. In contrast, for white-collar workers, emotional exhaustion weakened organizational commitment, ultimately leading to higher turnover intentions. Moreover, job resources enhanced job satisfaction and indirectly reduced turnover intentions for blue-collar workers, whereas these resources did not significantly predict job satisfaction among white-collar workers.Conclusion These findings underscore the importance of tailoring workplace strategies to different occupational groups in a non-Western setting. Strengthening job resources-particularly trust, leader support, and co-worker support-can enhance job satisfaction and reduce turnover risk among blue-collar workers. Conversely, for white-collar workers, mitigating job demands and managing emotional exhaustion are crucial for sustaining organizational commitment. This study contributes to the cross-cultural understanding of job demands and resources, highlighting their differential impact on blue- and white-collar workers in T & uuml;rkiye.
