Yayın Neuropsychiatric outcomes and caregiver distress in primary progressive aphasia(Wiley, 2023-01) Seçkin, Mustafa; Yıldırım, Elif; Demir, İlayda; Orhun, Ömer; Bülbül, Ezgi; Velioğlu, H. Aziz; Öget, Öktem; Yeşilot, Nilüfer; Çoban, Oğuzhan; Gürvit, HakanBackground: 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.Yayın Psychometric properties of the pathological buying screener: reliability and validity study(Kare Publishing, 2021-06) Dikbaş, Ganime Tuba; Acartürk, Ceren; Akyunus, MirayObjective: 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.Yayın 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 RobertObjective: 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.Yayın 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, VedatOBJECTIVES: 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.Yayın 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, ErdemPurpose: 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.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.
