undefinedEvery Time We Walk, It Is a Pride March!undefined A Conversation on the Everyday Politics of Queer Walking
(Routledge Journals, Taylor & Francis Ltd, 2025) Avşar, Erdem; Akıncı, Özgül
This is a critical-meditative conversation between artist-researchers Avşar and Akıncı. Reflecting on 'queer walking' in two cities, Istanbul and Glasgow, it takes walking as an ever-shifting and embodied site of everyday politics. Avşar and Akıncı draw on voice messages, letters, and texts exchanged between them to auto-ethnographically trace how their daily walks have been undulating with wider political pressures and more intimate contexts. Echoing the Istanbul pride slogan, 'Every time we walk, it is a pride march!', this dialogue insists on honouring the quiet political capacities of walking queerly without overlooking the vulnerabilities that such public mobility can carry in autocratic regimes.

Ericksonian Hypnotherapy versus Cognitive Behavioral Therapy for Post-Traumatic Stress Disorder
(Routledge Journals, Taylor & Francis Ltd, 2026) Çınaroğlu, Metin; Yılmazer, Eda; Noyan Ahlatcıoğlu, Esra; Hızlı Sayar, Gökben; Ülker, Selami Varol
Post-traumatic stress disorder (PTSD) is characterized by persistent psychological distress and heightened neurophysiological reactivity. While trauma-focused cognitive behavioral therapy (CBT) is an established treatment, Ericksonian Hypnotherapy (EH) may offer comparable benefits via different therapeutic mechanisms. In this randomized clinical trial, 63 adults meeting DSM-5 criteria for PTSD were allocated (1:1:1) to EH, CBT, or a waitlist control; 54 participants completed post-treatment assessments. Both active interventions consisted of 12 weekly individual sessions. Outcomes included PTSD symptom severity (PCL-5), depression (BDI-II), anxiety (BAI), EEG markers (N2, P3, frontal alpha asymmetry), and autonomic reactivity (galvanic skin response, heart rate). Group & times; Time effects were analyzed using mixed-effects models. Treatment fidelity was independently evaluated. Both EH and CBT produced large and significant reductions in PTSD symptoms compared with waitlist, with no significant difference between the two therapies in total PCL-5 improvement. Depression and anxiety symptoms also decreased substantially in both active groups. Subscale analyses suggested slightly greater reductions in intrusion, hyperarousal, and somatic anxiety symptoms in EH, whereas CBT showed modestly greater improvement in cognitive depressive symptoms. Neurophysiological findings demonstrated parallel treatment-related changes across therapies, including normalization of ERP components, shifts toward left-frontal alpha activity, and reduced autonomic reactivity to trauma cues. No adverse events were observed. In this study, Ericksonian Hypnotherapy was as effective as trauma-focused CBT for reducing PTSD symptoms and associated psychological and physiological dysregulation, supporting EH as a viable alternative intervention for PTSD.
Cognitive Behavioral Therapy Reduces Symptom Severity and Normalizes Neurophysiological and Attentional Reactivity in Anorexia Nervosa: A Randomized Controlled Trial
(MDPI, 2026) Yılmazer, Eda; Çınaroğlu, Metin; Hızlı Sayar, Gökben; Ülker, Selami Varol
Background: Anorexia nervosa (AN) is a severe psychiatric disorder marked by restrictive eating, distorted body image, and high relapse rates. While cognitive-behavioral therapy (CBT) is a widely used treatment, its mechanisms of action in AN remain incompletely understood, particularly beyond self-reported symptom change. This study investigated the effects of a 12-week CBT intervention on both clinical and multimodal laboratory-based outcomes in women with restrictive-type AN. Methods: In a two-arm, pre-post randomized controlled trial (ClinicalTrials.gov: NCT07037017), 59 women with restrictive-type AN were randomized to a CBT intervention (n = 30) or no-treatment control (n = 29). A total of 50 participants (CBT: 26; control: 24) completed baseline and post-intervention assessments and were included in analyses. Outcomes included psychometric measures (eating disorder symptoms, depression, anxiety, body image-related obsessive-compulsive symptoms, and cognitive emotion regulation) and laboratory-based indices: electroencephalography (EEG), galvanic skin response (GSR), and eye-tracking during exposure to food- and body-related stimuli. Group & times; Time effects were analyzed using repeated-measures mixed-effects models, and statistical analyses were conducted using SPSS (Version 31; IBM Corp., Armonk, NY, USA). Results: Significant Group & times; Time interactions indicated greater improvements in the CBT group across all psychometric outcomes, including reduced eating disorder symptom severity (p < 0.001, eta(2)(p) = 0.28) and increased adaptive emotion regulation. CBT participants also showed significant reductions in EEG P300 and late positive potential (LPP) amplitudes to body-related stimuli, increased frontal alpha asymmetry, decreased visual fixation on salient body and food cues, and attenuated GSR reactivity (all p < 0.05). Exploratory correlations revealed that symptom improvements were associated with reductions in neurophysiological and attentional reactivity. Conclusions: To our knowledge, this is the first RCT in AN to demonstrate that CBT not only improves self-reported outcomes but also modulates neurophysiological and attentional processes implicated in the maintenance of the disorder. Multimodal laboratory assessments provided mechanistic insight into treatment effects and may inform personalized intervention strategies. CBT appears to facilitate recovery through both cognitive-emotional and physiological recalibration.
Attenuated Rightward Hemispheric Asymmetry in ADHD: Structural MRI Evidence from a Normalized Asymmetry Index and Its Association with Cognitive Performance
(Frontiers Media SA, 2026) Tarlaci, Sultan; Cinaroglu, Metin; Yilmazer, Eda; Ulker, Selami Varol
Background Altered hemispheric asymmetry has been proposed as a potential neurodevelopmental feature of Attention-Deficit/Hyperactivity Disorder (ADHD). However, findings remain inconsistent, and the functional relevance of structural asymmetry patterns is not well established. This study examines volumetric and cortical-thickness asymmetries across cortical and subcortical regions in children and adolescents with ADHD compared to typically developing controls and evaluates their association with objective cognitive performance. Methods Forty participants with ADHD and 30 age- and sex-matched controls underwent high-resolution T1-weighted MRI. Bilateral regional volumes and cortical thickness were quantified using the volBrain pipeline, and asymmetry indices (AI = [R-L]/[(R + L)/2]) were computed for lobar and subcortical structures. Group differences were assessed using independent t-tests. Within the ADHD group, associations between asymmetry indices and MOXO-d-CPT performance (Attention, Timing, Impulsivity, Hyperactivity) were examined using Pearson correlations with correction for multiple comparisons. Results ADHD participants showed significantly reduced rightward asymmetry in frontal lobe volume, cerebellar hemispheres, caudate, putamen, and amygdala (ps < 0.05). Cortical-thickness asymmetry was also diminished in the frontal and parietal lobes and the anterior cingulate cortex. Temporal and occipital asymmetries were preserved. Within the ADHD group, greater rightward frontal and ACC thickness asymmetry correlated with better attention performance (r = 0.45 and 0.40), rightward parietal asymmetry associated with more accurate timing (r = 0.38), reduced rightward IFG asymmetry related to greater impulsivity (r = -0.42), and amygdala asymmetry correlated with lower hyperactivity (r = 0.36). Conclusion Children with ADHD exhibit a consistent attenuation of typical right-hemisphere dominance across frontal, striatal, cerebellar, and limbic systems. These altered asymmetry patterns are meaningfully associated with attentional control, timing accuracy, impulsivity, and hyperactivity, suggesting that hemispheric imbalance may serve as a structural may represent a neurodevelopmental characteristic associated with ADHD. Findings support models emphasizing right-hemisphere developmental lag and highlight hemispheric asymmetry as a clinically relevant dimension of ADHD neurobiology.

Green Marketing and Repurchase Intention in the Airline Industry: The Mediating Role of Electronic Word-of-Mouth
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Beğendik B.; Karadeniz S.; Beğendik, Behiye; Karadeniz, Serhan
The aviation industry faces increasing pressure to reduce its environmental footprint, prompting airlines to adopt green marketing practices that align with sustainability goals. Grounded in the Elaboration Likelihood Model (ELM), this study investigates the influence of green marketing on consumers’ repurchase intentions, with electronic word-of-mouth (e-WOM) as a mediating factor. An online survey was conducted among 390 airline passengers in Turkey, and the data were analyzed using structural equation modeling. The results indicate that green marketing significantly enhances both e-WOM and repurchase intention. Additionally, information quality and credibility exert significant effects on e-WOM and make a modest direct contribution to repurchase intention. While e-WOM is positively associated with repurchase intention, its mediating role in the relationship between green marketing and repurchase intention is not statistically supported. These findings suggest that e-WOM functions as a reinforcing rather than a transmitting mechanism linking green marketing to repurchase intention. The model explains 68.9% of the variance in repurchase intention and 18.9% in e-WOM. The study contributes by integrating green marketing, e-WOM, and information characteristics within an ELM-based framework for the airline context, offering actionable insights for sustainability-oriented marketing strategies. © 2026 by the authors.
Emotion Regulation and Visual Attention in Body Dysmorphic Disorder: A Multimodal Study Using EEG, GSR, and Eye-Tracking
(BMC, 2026) Ulker, Selami Varol; Cinaroglu, Metin; Yilmazer, Eda; Sayar, Gokben Hizli
BackgroundBody Dysmorphic Disorder (BDD) is a psychiatric condition characterized by obsessive preoccupation with perceived physical flaws, often accompanied by emotional dysregulation and attentional biases. Despite increasing clinical recognition, the neurophysiological and attentional mechanisms underlying BDD remain poorly understood.MethodsThis study employed a multimodal experimental design to compare individuals with BDD (n = 27) and healthy controls (n = 27). Participants completed standardized psychometric assessments and were exposed to emotionally valenced facial and body-related images while undergoing electroencephalography (EEG), galvanic skin response (GSR), and eye-tracking. Group-by-valence interactions were analyzed using mixed-model ANOVAs.ResultsThe BDD group showed significantly higher depression, anxiety, body image disturbance, and suppression scores, alongside reduced cognitive reappraisal and self-efficacy. EEG analyses revealed increased N170 amplitudes, attenuated P300 amplitudes, and greater right-sided frontal alpha asymmetry, suggesting early hypervigilance, reduced evaluative processing, and affective withdrawal. GSR data indicated heightened sympathetic arousal and delayed physiological recovery. Eye-tracking data descriptively indicated gender-specific attentional patterns within the BDD group, with females allocating greater visual attention to facial and lower-body regions and males showing increased fixation on muscular upper-body features; such patterns were not observed in the control group.ConclusionBDD is associated with dysregulated multisystem responses to appearance-related stimuli, characterized by neural hyperreactivity, impaired cognitive-emotional regulation, and gender-related patterns of visual attention. These findings support the utility of integrating psychophysiological and attentional markers into individualized assessment and intervention strategies for BDD.Clinical trial numberNot applicable.
A New Approach for Increasing the Photocatalytic Activity of Titanium Dioxide in Water Hydrolysis
(Pleiades Publishing Ltd, 2026) Kasapbasi, Emine Esra; Kirci, Serap; Hatipoglu, Arzu
Photocatalytic hydrogen production via water splitting is a sustainable and promising green technology. Producing clean hydrogen fuel using sunlight will significantly benefit the environment. TiO2 photocatalysts can split water into H-2 and O-2 under sunlight. However, the wide band gap of TiO2 (similar to 3.2 eV) limits its activity to UV-light, making it inactive under visible light. Doping with cations has been shown to enhance visible-light absorption and affect the photocatalytic properties of TiO2. Despite extensive research, there is still no clear explanation for how different cations influence its activity under solar irradiation. In this study, the non-defective anatase (001) surface was modeled using finite, neutral, stoichiometric cluster models derived from bulk anatase. Doped models were created by substituting one Ti atom with a cation, and their positions were optimized for minimum energy. Calculations were carried out using Density Functional Theory (DFT) with the B3LYP hybrid functional and the 6-31G(d) basis set. All dopants were found to reduce the TiO2 band gap, improving visible-light activity. Additionally, metal doping positively influenced water decomposition. Water showed a tendency to remain dissociated in clusters doped with +4 and +5 valence cations, indicating enhanced catalytic potential. Among these, the Ta5+-doped cluster exhibited the highest reaction energy, suggesting that future studies should focus on the reaction energetics of +5 valence doped systems to better understand their role in photocatalytic efficiency.
Coping Strategies and Psychological Outcomes Following the 2023 Kahramanmaraş Earthquakes: A Systematic Review with Meta-Analytic Synthesis
(Frontiers Media SA, 2026) Cinaroglu, Metin; Yilmazer, Eda
Background The 2023 Kahramanmara & scedil; earthquakes caused unprecedented devastation across southern T & uuml;rkiye, resulting in widespread psychological distress among survivors. Identifying coping strategies linked to better mental health outcomes is essential for guiding post-disaster support. Objective To systematically synthesize quantitative evidence on associations between coping strategies and psychological outcomes (PTSD/trauma symptoms, depression, anxiety, and posttraumatic growth [PTG]) among adult survivors of the 2023 earthquakes, and to meta-analyze associations reported in at least two independent studies. Methods Following PRISMA 2020 guidelines and a preregistered OSF protocol (osf.io/7z2pe), four databases (Web of Science, Scopus, PubMed, and DergiPark) were searched for quantitative studies published in Turkish or English. Ten cross-sectional studies (total N = 6,223) met inclusion criteria. Data were extracted using a standardized form, study quality was appraised with an adapted Newcastle-Ottawa Scale, and random-effects meta-analyses were conducted for coping-outcome pairs reported in >= 2 studies; remaining associations were summarized descriptively. Results Meta-analytic evidence indicated that resilience was consistently associated with lower psychological distress, including post-earthquake trauma severity (pooled r = -0.44), depression (r = -0.41), anxiety (r = -0.43), and overall distress across four studies (r = -0.42). Perceived social support/support-seeking coping was moderately associated with lower PTSD/trauma-related symptoms (pooled r = -0.31). Religious coping (pooled r = -0.21) and positive reappraisal (pooled r = -0.19) showed small inverse associations with PTSD symptoms but with substantial heterogeneity. In single-study analyses, meaning-centered coping and self-compassion were associated with higher PTG, suggesting potentially important pathways that require replication. Conclusion Coping processes are meaningfully linked to psychological adjustment after the Kahramanmara & scedil; earthquakes. The most robust evidence supports resilience and social support as protective correlates of lower distress. Evidence for religious coping and positive reappraisal is suggestive but heterogeneous, and PTG-related findings remain preliminary due to limited replication. Longitudinal and intervention-based research is needed to clarify causal mechanisms and inform culturally responsive disaster mental health programs.
Comparative Efficacy of Brief Psychoanalytic Psychotherapy and Cognitive Behavioral Therapy for Generalized Anxiety Disorder: A Randomized Controlled Trial
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Çınaroğlu M.; Yılmazer E.; Ülker S.V.; Hızlı Sayar G.; Çınaroğlu, Metin; Yılmazer, Eda; Hızlı Sayar, Gökben; Ülker, Selami Varol
Background: Cognitive behavioral therapy (CBT) is the most established psychological treatment for generalized anxiety disorder (GAD), yet many patients do not achieve full remission. Brief psychoanalytic psychotherapy represents a theoretically distinct alternative, but direct controlled comparisons remain limited. This study examined the short-term efficacy of brief psychoanalytic psychotherapy and CBT relative to a waitlist control in adults with GAD. Methods: In a three-arm randomized controlled trial, 60 adults with DSM-5-diagnosed GAD were allocated to brief psychoanalytic psychotherapy (12 weekly sessions), CBT (12 weekly sessions), or a waitlist control. Assessments were conducted at pre-treatment and post-treatment. The primary outcome was anxiety severity measured by the Beck Anxiety Inventory (BAI). Secondary outcomes included depressive symptoms (BDI-II), quality of life (WHOQOL-BREF), functional impairment (WHODAS 2.0), and therapeutic alliance (Working Alliance Inventory). Data were analyzed using mixed-design ANOVAs and effect size estimates. Results: Both active treatments produced significantly greater reductions in anxiety than the waitlist control, with large effect sizes. Mean BAI scores decreased by 14.5 points in the psychoanalytic group and 16.3 points in the CBT group, compared to minimal change in the waitlist condition. Similar patterns were observed for depressive symptoms, quality of life, and functional impairment, with both therapies outperforming waitlist controls on all secondary outcomes. No statistically significant differences were found between CBT and brief psychoanalytic psychotherapy on any outcome measure. Therapeutic alliance ratings were high and comparable across the two active treatments. Conclusions: Brief psychoanalytic psychotherapy and CBT were both effective short-term treatments for GAD and superior to no treatment, with no significant differences between the two modalities at post-treatment. These findings suggest that time-limited psychoanalytic psychotherapy may represent a promising short-term therapeutic option to CBT for GAD, expanding treatment options for patients and clinicians. © 2026 by the authors.
An Analysis of Airports’ Sustainability Promotion Activities on Instagram through Content Analysis Method
(IGI Global, 2026) Beğendik B.; Beğendik, Behiye
This study evaluates how airports in Türkiye communicate sustainability-related activities on Instagram by applying content analysis within the framework of the United Nations’ 17 Sustainable Development Goals (SDGs). The results indicate that airports post content related to the SDGs, but they mostly focus on economic and operational topics, especially SDG 9 (Industry, Innovation, and Infrastructure), which emphasizes digital advancements, new services, and infrastructure improvements. Airports display environmental themes, albeit in limited and uneven ways. From a strategic innovation perspective, airports tend to signal sustainability primarily through modernization and efficiency narratives rather than comprehensive environmental transformation. Accordingly, airport operators should move beyond symbolic messaging by communicating measurable environmental targets, actions, and outcomes on Instagram. © 2026 by IGI Global Scientific Publishing.

Persistent Urinary Tract Infections After Kidney Transplantation: Risk Factors and Management
(Elsevier Inc., 2026) Huseynov A.; Kuşlu Çiçek S.N.; Cicek, Sevim Nuran Kuslu; Kuşlu Çiçek, Sevim Nuran; Huseynov, Amil
Background: Persistent urinary tract infections (UTIs) are a frequent complication among kidney transplant recipients, often leading to increased morbidity, healthcare costs, and potential compromise of graft function. Identifying risk factors and effective management strategies is crucial to improve clinical outcomes in this vulnerable patient population. Methods: In this retrospective study conducted from January 2020 to December 2024, 1130 kidney transplant recipients aged 18 to 75 years were analyzed. Clinical and laboratory data were obtained from electronic medical records, with information on demographics, immunosuppressive regimens, microbiological findings, and treatment outcomes. Persistent UTIs were defined as 2 or more microbiologically confirmed episodes within 12 months despite appropriate therapy. Statistical analyses included descriptive measures, comparative tests, and multivariate logistic regression to identify independent predictors. Results: Of the total cohort, 31.2% developed persistent UTIs, with 68.5% experiencing recurrent episodes. Diabetes mellitus (adjusted OR: 1.56), prolonged urinary catheterization (adjusted OR: 2.04), and infection with multidrug-resistant (MDR) pathogens (adjusted OR: 2.32) emerged as significant risk factors. Escherichia coli was the most frequently isolated organism (36.4%), followed by Klebsiella pneumoniae and Pseudomonas aeruginosa. Patients with persistent UTIs exhibited lower mean eGFR levels, although graft loss rates did not differ significantly from those without persistent UTIs. Conclusion: Persistent UTIs represent a major clinical challenge in kidney transplant recipients. Early identification of modifiable risk factors—particularly glycemic control and appropriate urinary catheter management—may reduce recurrence and preserve renal function. A comprehensive approach involving routine microbiological surveillance and judicious antibiotic use is essential to mitigate the impact of MDR organisms on patient outcomes. © 2026

Desire and Absence in Rimini Protokoll's Conference of the Absent: A Lacanian Analysis of Audience Interviews
(John Wiley and Sons Ltd, 2026) Akıncı Ö.; Sümerkan H.H.; Akinci, Ozgul; Sumerkan, Hazal Hamarat
This paper explores the Conference of the Absent experience, a participatory theater piece produced by Rimini Protokoll, through a Lacanian psychoanalytic perspective. Drawing on semi-structured interviews with audience members who participated in the performance, it seeks to analyze the anxieties and resistances around performing, as well as how these experiences are retrospectively narrated and made sense of. Conference of the Absent is considered as a reconfiguration of the spectator-performer relation in a manner analogous to processes of subject formation in Lacanian psychoanalysis. The paper, thus, discusses how the performance destabilizes scopic mastery, repositions the voice as the central medium of subjectivation and situates the participants in a new system of meaning. Drawing from the audience interviews and analysis of the theatrical design, it is argued that the audience's engagement is less an act of personal agency than a pre-orchestrated response conditioned by the performance's dramaturgical design. This paper contributes to theater audience research by offering psychoanalytical theory as a methodological tool in understanding the workings of spectatorship in a participatory theater setting. © 2026 John Wiley & Sons Ltd.

Ericksonian Hypnotherapy: A Systematic Review and Meta-Analysis of RCTs
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Çınaroğlu M.; Yılmazer E.; Noyan Ahlatcıoğlu E.; Çınaroğlu, Metin; Yılmazer, Eda; Noyan Ahlatcıoğlu, Esra
Ericksonian hypnotherapy (EH), a client-centered hypnotic approach characterized by indirect suggestion, individualized flexibility, collaboration, and the principle of Utilization, has seen increased interest as a therapeutic modality across diverse clinical settings. This systematic review and meta-analysis aimed to evaluate the efficacy of EH by synthesizing evidence from randomized controlled trials (RCTs) published between 2015 and 2025. Eight eligible RCTs (N = 676) were identified, spanning conditions such as acute pain, depression, grief, irritable bowel syndrome, disordered eating, and alcohol use. EH interventions consistently produced significant symptom reductions compared to waitlists or standard care, with a pooled standardized mean difference of 1.17 (95% CI: 0.70–1.64), indicating a large effect. Moreover, trials comparing EH to active treatments (e.g., CBT, motivational interviewing) revealed comparable efficacy, with pooled estimates supporting non-inferiority. Sensitivity analyses confirmed the robustness of these findings. Notably, some trials suggested that the indirect and personalized nature of EH may confer advantages in domains like grief and hypervigilance. Although evidence remains limited by sample size and heterogeneity, this review provides initial empirical support for EH and supports its inclusion in the evidence-based repertoire for both physical and psychological conditions. Future research should examine mechanisms of change and individual predictors of response to optimize the use of this distinctive hypnotic style. © 2026 by the authors.

Solution to the Single Parametric Linear Programming Problems via Simplex-Based Algorithms: Handling the Uncertainties in Costs, Left or Right-Hand Sides
(Croatian Operational Research Society, 2026) Ergenecosar, Gizem Temelcan; Kocken, Hale Gonce; Albayrak, Inci; Sivri, Mustafa
Parametric programming is one of the notable approaches to expressing the uncertainties encountered in real life. Many studies express the parameters of the objective function and right-hand side parametrically, but only a few include the parametric coefficient matrix of the constraints. This paper examines the feasibility and optimality conditions of the simplex table and proposes a simplex-based algorithm (dual-simplex, generalized-simplex, or primal-simplex). In the solution process, each case is considered independently through the mathematical analysis of simplex multipliers. Distinct numerical examples illustrate each case to demonstrate the algorithm's implementation.
Resting-State EEG Power and Machine-Learning Classification in Adult Males with Gambling Disorder
(Frontiers Media SA, 2026) Cinaroglu, Metin; Yilmazer, Eda; Ulker, Selami Varol; Tarlaci, Sultan
Background: Gambling disorder (GD) is a behavioral addiction sharing neurobiological features with substance use disorders, yet objective biomarkers remain limited. This study examined resting-state EEG power and applied machine learning to identify potential electrophysiological markers of GD. Methods: Resting eyes-closed Electroencephalography (EEG) was recorded from 47 individuals with GD and 32 healthy controls. Absolute and relative power across delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) bands were quantified over eight cortical regions. Group differences and correlations with the South Oaks Gambling Screen (SOGS) were analyzed. Multiple comparisons were controlled using the Benjamini-Hochberg False Discovery Rate (FDR) correction. A Linear Discriminant Analysis (LDA) classifier was trained to differentiate GD from controls based on EEG features. Results: Group differences in EEG power were subtle, with GD showing significantly higher delta power in the left temporal region (p = 0.032, d = 0.43). Within the GD group, greater gambling severity was associated with higher absolute beta power across frontal, parietal, temporal, and occipital regions (r approximate to 0.40-0.50, p < 0.01), and these associations remained significant after FDR correction (pFDR < 0.05). The LDA model using absolute power achieved 73.7% classification accuracy (AUC = 0.74), whereas relative power yielded near-chance accuracy (57.9%). Conclusions: GD is characterized by subtle but meaningful EEG alterations, particularly increased beta activity linked to gambling severity. Multivariate EEG patterns can distinguish GD from controls, supporting the potential of resting-state EEG as a biomarker for clinical assessment and severity monitoring in behavioral addiction.
