    (Wiley, 2023-01) Seçkin, Mustafa; Yıldırım, Elif; Demir, İlayda; Orhun, Ömer; Bülbül, Ezgi; Velioğlu, H. Aziz; Öget, Öktem; Yeşilot, Nilüfer; Çoban, Oğuzhan; Gürvit, Hakan
    Background: In this study, we aimed to outline the neuropsychiatric consequences of primary progressive aphasia (PPA) and to understand how neuropsychiatric symptomatology affects distress in caregivers. Methods: The Neuropsychiatric Inventory (NPI) including the distress index (NPI-Distress) was used. Additional information about the caregiver burden was obtained using Zarit Burden Interview (ZBI). NPI, NPI-Distress, and ZBI data from 17 patients with a clinical diagnosis of PPA were compared with 10 stroke aphasia patients. Neuropsychiatric symptomatology was investigated based on three clusters; Mood, Frontal/Comportmental, and Psychotic/Disruptive. Additionally, the Activities of Daily Living Questionnaire (ADLQ) was used to outline the functional impairment. Twelve healthy controls were included to compare the neurocognitive test scores with PPA and stroke aphasia groups. Results: A greater number of neuropsychiatric symptoms were observed in the PPA group compared to the stroke aphasia group. The number of symptoms in Mood, and Frontal/Comportmental clusters were greater than the number of symptoms in Psychotic/Disruptive clusters in the PPA group, whereas no significant relationship between the number of symptoms and symptom clusters was found in the stroke aphasia group. In the PPA group, a strong correlation was found between the NPI-Frequency × Severity scores and the NPI-Distress scores. Moreover, the NPI-Distress scores in the PPA group strongly correlated with the ZBI scores. Scores for anxiety, irritability/lability, and apathy had a stronger correlation with the NPI-Distress scores compared to the other NPI symptoms. The Communication subscale was the most impaired domain in the PPA group. Travel, and Employment and Recreation subscales showed greater functional impairment in the stroke aphasia group compared to the PPA group. Conclusions: Neuropsychiatric symptoms in PPA in our study were more frequent than previously reported. Furthermore, the distress index of the NPI was not only correlated with the severity of the neuropsychiatric symptoms but also reflected the overall burden on the caregivers in the PPA group.

    Eye movement desensitization and reprocessing therapy in adolescents with panic disorder: a twelve-week follow-up study
    (SAGE Publications Ltd, 2023-06-16) İnci İzmir, Sevim Berrin; Korkmazlar, Ümran; Ercan, Eyüp Sabri
    The aim of this study is to investigate the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) treatment in adolescents with panic disorder (PD). This follow-up study consists of 30 adolescents with PD without agoraphobia, aged 14–17 (15.53 ±.97). They were evaluated with Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children Present, also the Panic and Agoraphobia Scale (PAS) and Beck Anxiety Inventory (BAI) were administered at baseline, at the end of the 4th and 12th weeks of treatment. EMDR therapy which is an eight-phase treatment approach composed of standardized protocols and procedures was applied for 12 weeks, one session per week. The baseline mean of the total PAS score decreased from 40.06 to 13.13 at fourth week and 1.2 at the end of 12th week of treatment. In addition, BAI score decreased significantly from 33.67 to 13.83 at 4 weeks and 5.31 at the end of 12th week of treatment. Overall, our results underscore the effectiveness of EMDR in adolescents with PD. Moreover, the current study suggests that EMDR may represent an effective intervention technique for PD in adolescents to protect against relapses and to overcome a fear of future attacks.

    Psychometric properties of the pathological buying screener: reliability and validity study
    (Kare Publishing, 2021-06) Dikbaş, Ganime Tuba; Acartürk, Ceren; Akyunus, Miray
    Objective: The Pathological Buying Screener (PBS) is a self-report scale used to evaluate compulsive buying behavior. The aim of this study was to assess the validity and reliability of a Turkish version of the PBS in a nonclinical sample. Method: A total of 457 adult participants aged 18-64 years were enrolled in this study. Internal consistency, test-retest reliability and structure, concurrent and criterion-related predictive validity analyses were conducted to ensure reliability and validity for use of the scale with a Turkish population. As part of the validity study, all of the participants were asked to complete a battery of self-report scales: the Compulsive Buying Scale, the Brief Symptom Inventory, the Rosenberg Self-Esteem Scale, the Barratt Impulsiveness Scale-Short Form, and the PBS. In order to examine the test-retest reliability, 75 participants were asked to complete the questionnaire once again 2 weeks after the first administration. Results: The results of this study revealed that the PBS had good internal consistency and test-retest reliability. The findings supported concurrent and criterion-related predictive validity, and a 2-factor structure, consistent with the original form. Conclusion: The Turkish version of the PBS is a valid and reliable measurement tool that will add to understanding of pathological buying behavior.

    Normative data and factorial structure of the Turkish version of the junior temperament and character inventory-revised
    (Taylor & Francis, 2017) Köse, Samet; Çam Çelikel, Feryal; Akın, Ercan; Kaya, Cahit; Elbozan Cumurcu, Birgül; Etikan, İlker; Cloninger, Claude Robert
    Objective: Junior Temperament and Character Inventory (J-TCI) was developed by Luby, Svrakic, McCallum, Przybeck, and Cloninger based on Cloninger's biopsychosocial model to assess temperament and character dimensions in children and adolescents. Methods: The Turkish version of J-TCI-Revised (J-TCI-R) was administered to 1129 elementary and middle-school (male/female, 546/583) students. Internal consistency reliabilities were measured by Cronbach's alpha; test-retest was assessed across one month. Results: Cronbach's alphas for the subscales of J-TCI-R ranged from 0.60 to 0.75 for temperament and character subscales, which were comparable to US and other populations. The correlations between baseline and one month after administration of J-TCI-R were highly and statistically significant (r = 0.578-0.674 for scales and 0.366-0.582 for subscales) (n = 795). Factor analysis results using Eigenvalue greater than one rule indicated three out of four factors for temperament scales and one out of two factors for character subscales which were similar to findings from the other countries. When all of the subscales were subjected to factor analysis, four out of six factors were retained. To our knowledge, this is the first study analysing psychometric properties and factorial construct of the J-TCI-R. Conclusions: The internal reliability coefficients and test-retest indicated a good stability of scores over time and the factorial structure was consistent with Cloninger's model of personality. The reliability and validity of the Turkish version of the TCI is therefore supported.

    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 Sabri
    This 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.

    Bu araştırmanın amacı F.M.V. Işık Üniversitesi Mühendislik Fakültesinde öğrenim gören öğrencilerin genel öz-yeterlilik algılarının ve Programlamaya Giriş(CSE101) dersine yönelik tutumlarının; cinsiyet ve eğitim aldıkları programın diline (Türkçe-İngilizce) göre incelenmesidir. Araştırmaya 40 kadın ve 74 erkek olmak üzere toplam 114 üniversite öğrencisi katılmıştır. Öğrencilerin öz yeterlilik algılarını ölçmek için Genel Öz Yeterlilik ölçeği kullanılmış, ders sonucunu (başarı ve başarısızlık) değerlendirmeleri için açık uçlu sorular sorulmuş ve yaş, cinsiyet gibi temel demografik bilgileri alınmıştır. Açık uçlu sorular niteliksel (kalitatif) analiz yöntemi ile incelenmiştir. Yapılan niceliksel analiz sonucunda öğrencilerin genel öz-yeterlilik puanları ile genel not ortalaması arasında anlamlı, CSE101 dersi dönem sonu not ortalaması arasında ise anlamsız bir ili ki olduğu bulgulanmıştır. Ayrıca öğrencilerin öz-yeterlilik puanlarının cinsiyete ve eğitim aldıkları dile göre (Türkçe-İngilizce) değişmediği görülmüştür. Öğrencilerin motivasyon puanları da eğitim aldıkları dile göre farklılaşmamaktadır. Niteliksel analiz bulgularına göre ise öğrencilerin verdiği cevapların yüzde sıklık değerlerinin cinsiyetleri açısından değiştiği görülmüştür. Bu çalışmanın sonuçları özellikle öğrencilerin derse yönelik tutumlarında cinsiyet açısından bir farklılık olduğunu göstermesi ile mühendislik programlama eğitiminde öğrenci başarısını yordayan değişkenlerin tespit edilmesi sürecine katkı sağlaması beklenmektedir.

    Reliability, validity, and factorial structure of the Turkish version of the Empathy Quotient (Turkish EQ)
    (Taylor & Francis Ltd, 2018-07-03) Köse, Samet; Çam Çelikel, Feryal; Kulacaoğlu, Filiz; Akın, Ercan; Yalçın, Mehmet; Ceylan, Vedat
    OBJECTIVES: Empathy is an essential ability that allows us to tune into how others are feeling or thinking. Empathy makes it possible to resonate with others' positive and negative feelings alike so that we can thus feel happy when we vicariously share the joy of others and we can share the experience of suffering when we empathize with someone in pain. Empathy training not only promotes prosocial behaviour, but also augments positive affect and resilience, which in turn fosters better coping with stressful situations. The Empathy Quotient (EQ) is a self-report questionnaire that was developed to measure the cognitive, affective, and behavioural aspects of empathy. Here, we aimed to examine the validity, reliability, and factor structure of the EQ in a Turkish sample. METHODS: Participants were 436 mostly college students and civil servants (195 female, 241 male). Sociodemographic information, the Turkish version of the EQ, Marlowe-Crowne Social Desirability Scale (MC-SDS) 33-item full version and MC-SDS 13-item shorter versions were administered. All statistical analyses were performed by using SPSS version 23 for Windows. RESULT: EQ scores were significantly higher in female participants ((X) over bar (Female)=46.45, SDFemale=0.62) compared to the male participants ((X) over bar (Male)=43.68, SD (Male)=0.56). The Cronbach's alpha coefficient for the scale was 0.76, Guttman's split-half reliability coefficient was 0.61, and test-retest reliability coefficient was 0.95. A positive and statistically significant correlation was found between the Turkish EQ and MC-SDS Full version (r=0.299, p<.01) and short form of MC-SDS (r=0.273, p<.01). A three-factor solution that accounted for 25.28% of the variance observed. CONCLUSIONS: The Turkish version of the EQ has satisfactory validity, good internal and test-retest reliability with a robust factorial structure to use in a clinical population in Turkey. Moreover, as predicted, women scores were statistically significantly higher on the EQ than men. This result was consistent with a series of earlier studies reporting gender differences (female superiority) on questionnaires that measure empathy. A better knowledge of empathy will have important implications for the examination and understanding of certain neurological and psychiatric disorders, including autism, narcissistic and antisocial personality disorders, and may also provide important clues about the relevant brain circuitry underlying empathy.

    (Işık Üniversitesi, 2020-05-20) Ökke, Enna; Ergüney Okumuş, Fatima Elif; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Klinik Psikoloji Yüksek Lisans Programı
    Amaç: Bu araştırmada çeşitli ülkelerde kullanılan, uluslararası kabul görmüş Hamilton Depresyon Derecelendirme Ölçeği'nin Ermenice formunun geçerlik ve güvenirlik çalışmasının yapılması amaçlanmıştır. Yöntem: İlk olarak HDDÖ’nün pilot çalışması gerçekleştirilmiştir. Pilot çalışma örneklemini, hastanenin psikiyatri kliniğine depresif yakınmalarla başvuran ve psikiyatrist tarafından değerlendirilip depresyon tanısı alan 20 hasta oluşturmuştur. Sosyodemografik bilgi formu ve bağımsız olarak 2 uzman tarafından değerlendirilen HDDÖ tüm katılımcılara uygulanmıştır. Pliot çalışmada ölçeğin güvenirlik analizi; Cronbach alpha (.80), iki yarıya bölme (.88) ve madde toplam korelasyon analizleri (uzman1 için .34 ile .89 arasında; uzman2 için .36 ile .88 arasında) 17 maddelik HDDÖ için hesaplanmıştır. Bu sonuçlar, ölçeğin yüksek güvenirliğe sahip olduğunu gösterir. Puanlayıcılar arasındaki korelasyon katsayısı (%99) ve kappa katsayısı (.82) yüksek düzeyde ilişkili ve anlamlı bulunmuştur. Pilot çalışmanın ardından ana çalışmaya geçilmiştir. Ana Çalışmanın örneklemini; hastanenin psikiyatri kliniğine depresif yakınmalarla başvuran ve psikiyatrist tarafından değerlendirilip depresyon tanısı alan 82 hasta ile sağlıklı kontrol grubu olarak hastane çalışanlarından 52 kişi oluşturmuştur. Sosyodemografik bilgi formu, bireyin kendini değerlendirdiği CES-D ölçeği ve bağımsız olarak 2 uzman tarafından değerlendirilen HDDÖ tüm katılımcılara uygulanmıştır. Bulgular: Depresif grubun demografik değişkenleri (cinsiyet, medeni durum, eğitim düzeyi, gelir düzeyi, intihar girişimi, ailede psikiyatrik rahatsızlık vs.) ile HDRS skorları arasındaki korelasyonlar incelenmiştir. Kadınların HDRS skorları anlamlı derecede yüksek bulunmuştur. Ölçeğin geçerliği ilk olarak benzer ölçek geçerlik yöntemiyle HDDÖ toplam puanı ile CES-D toplam puanları arasındaki ilişkiye bakılarak değerlendirilmiştir. HDDÖ ve CES-D puanları (.81) arasında arasında pozitif yönde istatistiksel olarak anlamlı korelasyon bulunmuştur. Daha sonra ölçeğin ayırt edici geçerliği t-test ile incelenmiş ve depresif grubun HDDÖ puanları sağlıklı kontrol grubundan istatistiksel olarak anlamlı düzeyde yüksek bulunmuştur (p<0,05). HDDÖ’nün depresif olan ve olmayan grupları birbirinden ayırt edebildiği görülmüştür. Ölçeğin güvenirlik analizi; Cronbach alpha (.97), iki yarıya bölme (.96) ve madde toplam korelasyon analizleri (uzman1 için .48 ile .92; uzman2 için .46 ile .92) 17 maddelik HDDÖ için hesaplanmıştır. Bu sonuçlar, ölçeğin yüksek güvenirliğe sahip olduğunu gösterir. Puanlayıcılar arasındaki korelasyon katsayısı (%99) ve kappa katsayısı (.95) yüksek düzeyde ilişkili ve anlamlı bulunmuştur. ROC analizi ile kesme puanı >6 olarak belirlendi. Sonuç: Çalışma sonuçları, Hamilton Depresyon Derecelendirme Ölçeği’nin Ermenice Formunun geçerli ve güvenilir olduğuna dair destek sunmaktadır.

    Elevated sTREM2 and NFL levels in patients with sepsis associated encephalopathy
    (Taylor & Francis, 2023-03-04) Orhun, Günseli; Esen, Figen; Yılmaz, Vuslat; Ulusoy, Canan; Şanlı, Elif; Yıldırım, Elif; Gürvit, İbrahim Hakan; Ergin Özcan, Perihan; Sencer, Serra; Bebek, Nerses; Tüzün, Erdem
    Purpose: Sepsis-associated encephalopathy (SAE) is a common manifestation of sepsis that may lead to cognitive decline. Our aim was to investigate whether the neurofilament light chain (NFL) and soluble triggering receptor expressed on myeloid cells 2 (sTREM2) could be utilized as prognostic biomarkers in SAE. Materials and methods: In this prospective observational study, baseline serum levels of sTREM2 and cerebrospinal fluid (CSF) levels of sTREM2 and NFL were measured by ELISA in 11 SAE patients and controls. Patients underwent daily neurological examination. Brain magnetic resonance imaging (MRI) and standard electroencephalography (EEG) were performed. Cognitive dysfunction was longitudinally assessed after discharge in 4 SAE patients using the Mini-Mental State Examination (MMSE) and Addenbrooke’s Cognitive Examination-Revised (ACE-R) tests. Results: SAE patients showed higher CSF sTREM2 and NFL levels than controls. sTREM2 and NFL levels were not correlated with the severity measures of sepsis. Three months after discharge, 2 SAE patients displayed ACE-R scores congruent with mild cognitive impairment (MCI), persisting in one patient 12 months after discharge. SAE patients with MCI showed higher CSF NFL levels, bacteremia, and abnormal brain MRI. Patients with increased serum/CSF sTREM2 levels showed trends towards displaying poorer attention/orientation and visuo-spatial skills. Conclusions: sTREM2 and NFL levels may serve as a prognostic biomarker for cognitive decline in SAE. These results lend further support for the involvement of glial activation and neuroaxonal degeneration in the physiopathology of SAE.

    Exploring the impact of Flash technique on test anxiety among adolescents
    (SAGE Publications Ltd, 2025-07) Çitil Akyol, Canan; İnci İzmir, Sevim Berrin
    This study aims to investigate the specific effects of Flash Technique (FT) on adolescents with test anxiety. This follow-up study consists of 38 adolescents, 14–17 years of age (M = 15.39, SD = 1.13). Pre-post assessments were conducted using the Test Anxiety Inventory (TAI), Scale of Attitudes Negatively Affecting the Performance I/Test (POET), and Beck Anxiety Inventory (BAI) at baseline, at the end of the 4thand 12thweeks of therapy. The FT was applied for 12 weeks, with one weekly session as an intervention. As a result of the therapy process, the baseline means of total BAI scores decreased from 25.26 to 2.18; the baseline means of TAI decreased from 149.79 to 39.13, and the baseline mean of POET decreased from 298.47 to 73.84 at the end of the 12th week of therapy. Also, the baseline means of SUD scores decreased from 9.42 to zero at the end of the 12th week of treatment. All the adolescents showed complete improvement after the 12th week of the FT. The study findings showed that the test anxiety symptoms significantly decreased with the treatment of the FT. FT can be an effective intervention for test anxiety in adolescents.
