  • Çocuk ve Ergen Psikiyatrisi Konsültasyon İstemlerinin 10 Yıllık Değişimi: Bir Üniversite Hastanesinden Karşılaştırmalı Bir Çalışma

    by Ayşegül Tuğba Hıra Selen, Hurşit Ferahkaya, Ali Türker Çiftçi

    Amaç: Bu çalışmanın amacı, bir üniversite hastanesinde çocuk ve ergen psikiyatrisine yönlendirilen konsültasyon istemlerinin 10 yıl içindeki değişimini incelemektir.Gereç ve Yöntemler: Retrospektif dosya taraması yapılarak 2014 ve 2024 yıllarına ait 1 yıllık konsültasyon formları, yaş, cinsiyet, başvuru nedeni, hizmeti isteyen klinik, tanı, öneri gibi değişkenlere göre karşılaştırıldı.Bulgular: Konsültasyon sayısı 2014’ten 2024’e artmış; istemlerin kaynak dağılımı pediatri polikliniği ağırlığından yataklı servislere doğru kaymıştır. Bölüm bazında 2024’te çocuk endokrinoloji ve hematoloji-onkolojiden gelen istemler artmış, çocuk nöroloji, fizik tedavi rehabilitasyon (FTR), çocuk cerrahiden gelen istemler azalmıştır. Tanısal profilde, 2014’te “tanı yok” ve özgül öğrenme bozukluğu (ÖÖG) daha sık iken; 2024’te depresyon, dikkat eksikliği ve hiperaktivite bozukluğu (DEHB) ve otizm spektrum bozukluğu (OSB) oranlarında anlamlı artış saptanmıştır. Tedavi örüntüsü de değişmiş; 2024’te antipsikotik ve metilfenidat reçetelenmesi ile “daha önce psikiyatrik tedavi öyküsü” anlamlı olarak daha yüksekti.Sonuç: Bulgular çocukluk ve ergenlik çağında ruhsal gereksinimin arttığını ve Konsültasyon-Liyezon hizmetlerinin hastane örgütlenmesi ve klinik iş akışlarıyla birlikte evrildiğini düşündürmektedir. Çocuk sağlığı ve hastalıkları ile çocuk psikiyatri alanı arasındaki iş birliğinin artması ve karşılıklı sorunların irdelenerek çözümlenmesi çocuk hastaların tedavilerinin daha hızlı ve etkili yapılabilmesi açısından önem taşımaktadır.

    Cyberbullying involvement in adolescence: Associations with emotion regulation, metacognitive beliefs, loneliness, and perceived social support in a cross-sectional study

    by Fatma Coşkun, Hasibe Ağir, Hurşit Ferahkaya, Ömer Faruk Akça

    Cyberbullying is an increasingly prevalent public mental health concern during adolescence and is associated with substantial emotional and interpersonal difficulties. In this cross-sectional, school-based study, we examined the interrelated associations of emotion regulation difficulties, maladaptive metacognitive beliefs, loneliness, perceived social support, and duration of social media use with cybervictimization and cyberbullying perpetration in a school-based sample of 600 adolescents aged 14 to 18 years. Participants completed the Revised Cyber Bullying Inventory–II, the Metacognitions Questionnaire for Children, the Difficulties in Emotion Regulation Scale–Short Form (DERS-SF), the UCLA Loneliness Scale–Short Form, and the Multidimensional Scale of Perceived Social Support (MSPSS). Cybervictimization was positively associated with DERS-SF ( r = 0.36, P < .001), MCQ-C ( r = 0.25, P < .001), and the UCLA Loneliness Scale–Short Form ( r = 0.22, P < .001), and negatively associated with MSPSS-total scores ( r = −0.19, P < .001). In hierarchical regression analyses, gender (β = −0.190, P < .001), DERS-SF total scores (β = 0.284, P < .001), MCQ-C total scores (β = 0.104, P = .02), and the MSPSS family subscale (β = −0.119, P = .004) significantly predicted cybervictimization ( R 2 = 0.186). Structural equation modeling showed indirect associations between emotion regulation difficulties, perceived social support, and cybervictimization through loneliness. Cyberbullying perpetration was positively associated with DERS-SF total scores ( r = 0.22, P < .001), MCQ-C total scores ( r = 0.11, P < .05), and negatively associated with the MSPSS family subscale ( r = −0.17, P < .001). In regression analyses, gender (β = −0.212, P < .001), DERS-SF total scores (β = 0.267, P < .001), and the MSPSS family subscale (β = −0.111, P = .01) significantly predicted cyberbullying perpetration ( R 2 = 0.108). Structural equation modeling analyses further suggested that loneliness may play a role in the association between emotion regulation difficulties, perceived family support, and cyberbullying perpetration. Overall, the findings suggest that adolescents’ involvement in cyberbullying-related behaviors may be associated with a broader psychosocial framework involving emotional dysregulation, maladaptive metacognitive beliefs, loneliness, and perceived social support. These findings may contribute to the development of multidimensional prevention and intervention approaches targeting emotional, cognitive, and interpersonal processes in adolescents.

  • The effect of Parental Attitudes on Eating Behaviors and HbA1c Levels in Children Diagnosed with Type 1 Diabetes

    by Hurşit Ferahkaya, Elif Nur Yaşar

    Background: Parental attitudes and feeding behaviors are considered important factors associated with self-management skills and metabolic control in children and adolescents with type 1 diabetes (T1D). However, there are different views on this role in the literature. This study aimed to investigate the associations between parental attitudes, children’s eating behaviors, and HbA1c levels in youth diagnosed with T1D. Methods: This cross-sectional study included 105 children and adolescents aged 7–18 years diagnosed with T1D for at least six months and followed at a pediatric endocrinology clinic. Parental attitudes were assessed using the Parent Attitude Scale (PAS) and eating behaviors using the Children’s Eating Behavior Questionnaire (CEBQ). Analyses were performed by dividing the participants into three groups according to their HbA1c levels (9.0). Results: Parents of children in the 9.0 group (p = 0.031). The “Desire to Drink” score was significantly higher in the 7.5–9.0 and >9.0 groups compared with the <7.5 group (p = 0.014). HbA1c levels showed negative correlations with PAS Acceptance/Interest and Auton-omy scores, and a positive correlation with the CEBQ Desire to Drink subscale. Additionally, Acceptance/Interest was negatively correlated with Emotional Overeating. Conclusion: Lower parental autonomy support and increased desire for sweetened beverages were associated with poor-er metabolic control in children with T1D. These findings suggest that supportive and autonomy-promoting parenting practices, as well as beverage-related eating behaviors, may be relevant clinical targets in routine T1D care. Family-based psychoeducation and structured parental guidance may therefore be considered as potentially useful components of comprehensive diabetes management.

    Emotion Regulation and Temperament Characteristics in Children and Adolescents Diagnosed With Migraine and Tension-Type Headache

    by Hurşit Ferahkaya, Ayhan Bilgiç, Melek Türker, Fatih Mehmet Akif Özdemir, Doğukan Mustafa Keskin

    Objective This study aimed to investigate the relationship between headache and psychiatric characteristics by comparing emotion regulation skills, temperament traits, and psychiatric symptom severity among children and adolescents diagnosed with migraine and tension- type headache (TTH) versus healthy controls.Methods A total of 131 participants aged 9–18 years were included: 45 with migraine, 42 with TTH, and 44 healthy controls. Assessments included the Difficulties in Emotion Regulation Scale (DERS), the Early Adolescent Temperament Questionnaire–Revised, and the Revised Child Anxiety and Depression Scale.Results Migraine patients had significantly higher scores on DERS subscales related to difficulty maintaining goal-directed behavior and developing effective coping strategies, as well as on major depressive disorder scores, compared to controls. TTH patients showed significantly lower effortful control scores, associated with attention and self-regulation, than the control group. No significant differences were found between the migraine and TTH groups in emotion regulation or temperament traits.Conclusion The findings suggest that both migraine and TTH may be associated not only with secondary psychiatric disorders such as depression and anxiety, but also with innate structural predispositions (emotion regulation skills and temperament characteristics). These shared structural predispositions may contribute to the development of both headache types and psychiatric symptoms.

    Concurrent Assessment of Neurotrophic Factors and HPA-Axis Hormones in Early Childhood Autism Spectrum Disorder

    by Hurşit Ferahkaya, Ayşegül Tuğba Hira Selen, Şeyma Tezer, Ömer Faruk Akça, Abdullah Akkuş, İbRahim Kılınç, Fatma Coşkun

    Purpose: Neurotrophic pathways and hypothalamic–pituitary–adrenal (HPA) axis regulation have been implicated in autism spectrum disorder (ASD), yet peripheral findings—particularly in early childhood—remain inconsistent. We examined peripheral neurotrophic factors and HPA-axis hormones in medication-naïve young children with ASD and evaluated their associations with clinical severity. Methods: This cross-sectional study included 45 medication-naïve children with ASD (18–72 months) and 52 age-matched healthy controls. ASD diagnosis was established per DSM-5, supported by the Childhood Autism Rating Scale (CARS) and the Autism Behavior Checklist (ABC). Morning samples (08:30–09:30) were assayed for serum BDNF, GDNF, NT-3, VEGF, cortisol, and plasma ACTH. Group comparisons used ANCOVA adjusted for age, sex, and BMI-for-age z score (BAZ), with Benjamini–Hochberg false discovery rate (FDR) correction. Within-ASD associations were tested using covariate-adjusted partial Spearman correlations. Results: BDNF was significantly lower in ASD than controls and remained significant after covariate adjustment and FDR correction. No between-group differences were observed for GDNF, NT-3, VEGF, ACTH, or cortisol. Within the ASD group, lower BDNF correlated with higher CARS total scores and higher ABC relating, social and self-help, and total scores. No significant correlations were found between neurotrophic factors and ACTH/cortisol. Conclusions: In medication-naïve children with ASD aged 18–72 months, peripheral BDNF is reduced and relates to symptom severity and adaptive/social difficulties, whereas other neurotrophic factors and basal HPA-axis hormones do not differ from controls. Longitudinal studies incorporating standardized sampling and diurnal/stress-reactivity indices are needed to clarify developmental dynamics and clinical implications.
