Yayın Assessing the mediating relationships between psychological factors in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome(Routledge Journals, Taylor & Francis Ltd, 2024-04) İnci İzmir, Sevim Berrin; Aktan, Zekeriya Deniz; Ercan, Eyüp SabriThis study aims to investigate the predictive and mediating relationships between emotion dysregulation, internalizing disorders, family functionality, loneliness preference, and executive functions (EF) in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome (ADHD + CDS). This study included 176 children and adolescents (92 boys, 84 girls) who were diagnosed with ADHD + CDS according to the Diagnostic and Statistical Manual of Mental Disorders, the Fifth Edition criteria by a fellowship-trained child and adolescent psychiatrist, between ages 8 -12 (M = 10, SD = 1.52) with a convenience sampling method. The solitude scale for children, difficulties in emotion dysregulation scale, Child Behavior Checklist, Barkley Sluggish Cognitive Tempo Scale, Family assessment device, and CNS Vital Signs test were used. The results showed that difficulty in emotion regulation, preference for loneliness, internalizing disorders and CDS symptom severity did not have a mediating effect between family functionality and EF. Still, emotion dysregulation mediates the relationship between EF and internalizing disorders by itself and through loneliness preference. Also, preference for loneliness and emotion dysregulation had a mediating effect between family functionality and internalizing disorders. Finally, it was found that the effect of emotion regulation difficulty, loneliness preference, and internalizing disorders had a mediating role between CDS symptom severity and family functionality. In conclusion, the information obtained from this study on the etiology of CDS may guide future studies.Yayın The relationships of neuropsychological factors and loneliness preference in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome(Routledge Journals, Taylor & Francis Ltd, 2025-04-03) İzmir, Sevim Berrin İnci; Aktan, Zekeriya Deniz; Ercan, Eyüp SabriThis study aimed to examine emotion dysregulation and internalizing disorders mediating the relationship between selective and sustained attention and loneliness preference in children diagnosed with attention deficit hyperactivity disorder (ADHD) and Cognitive Disengagement Syndrome (CDS). This study included 176 children and adolescents between ages 8 and 12. The solitude scale for children, Difficulties in Emotion Regulation Scale, Child Behavior Checklist, Barkley Sluggish Cognitive Tempo Scale, and CNS Vital Signs test were used. The results suggest that difficulties in emotion regulation and having an internalizing disorder had a mediating effect between difficulties in selective attention and preference for the loneliness of children with ADHD + CDS. Also, it was likely that the association between sustained attention and preference for loneliness is mediated by internalizing disorders. The results suggest that the social problems commonly exhibited by children with ADHD + CDS may be related to deficits in sustained and selective attention.Yayın Emotion dysregulation as a mediator between parental emotional availability and game addiction among Turkish late adolescents(Routledge, 2025-02) Ülkümen, İpek; Aktan, Zekeriya DenizThis study aimed to examine how difficulty in emotion regulation mediates the relationship between parental emotional availability and game addiction among Turkish late adolescents. 537 adolescents completed the Lum Emotional Availability of Parents, the Difficulties in Emotion Regulation Scale, Internet Gaming Disorder Short Form, and Sociodemographic Characteristics and Data Form. The results show that difficulty in emotion regulation fully mediates between parental emotional availability scores and adolescents’ game addiction scores. It can be concluded that interventions for the prevention and treatment of game addiction in late adolescents should focus on improving the parents’ emotional support and adolescents’ emotion regulation skills.Yayın The role of inner speech in modulating electrophysiological stress responses(Işık Üniversitesi Yayınları, 2026-04-29) Kaleem, Zayna Syed; Küçük, ZeynepThe frequency and reliance on inner speech (IS) vary across individuals and may influence selfregulation processes such as emotion regulation and impulse control. This study examined whether IS frequency is associated with differences in emotion regulation, impulsive behavior, and physiological stress responses. The sample consisted of 35 university students aged 18–39. IS frequency was treated as a continuous predictor. Associations between IS frequency, self-report measures of emotion regulation and impulsivity, task performance (Stroop task), and physiological responses (heart rate (HR) and skin conductance level (SCL)) were analyzed using correlation, linear regression, and repeated-measures ANOVA. Results showed no significant associations between IS frequency and emotion regulation, impulsivity, Stroop task accuracy, or reaction times. A significant main effect of task condition on SCL was observed, with mental arithmetic eliciting higher electrodermal activity than baseline and Stroop conditions, confirming successful stress induction. However, regression analyses revealed no relationship between IS frequency and physiological responses across tasks. The only significant finding emerged at baseline: higher IS frequency predicted lower resting HR (β = −.48, p = .004, R² = .23). Overall, IS frequency did not substantially influence cognitive or physiological outcomes. Future research should use larger samples, counterbalanced designs, and alternative measures to better capture dynamic stress-related processes.
