    (Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2019) Kilic, Neslihan; Oyekcin, Demet Gulec; Akinci, Erhan
    Objective: The aim of this study was to investigate the relationship between chronotype and temperament in patients with unipolar depression and the effect of chronotype on suicide risk. Methods: The participants consisted of patients with unipolar depression who were eligible for inclusion and exclusion criteria. Subjects were interviewed with the Structured Clinical Interview for DSM-5 and HAM-D, HAM-A scales. Patients filled the Morningness-Eveningness Questionnaire (MEQ), the Pittsburgh Sleep Quality Index, the Suicide Probability Scale and the Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire. Results: The participants were admitted female (n = 69) and male (n = 19). The rate of past suicide attempts was 24.1%. 50% of the patients had moderate depression and 50% of them had mild depression. According to MEQ scores patients were classified into three groups: 30.7% of them were eveningness, 58% of them were neither (intermediate) and 11.4 % of them were morningness type. The 90.8% of the patients had poor sleep quality. Depressive temperament was the most common temperament in the participants. Chronotype preference was not found to be associated with depression severity, anxiety, suicide probability, sleep quality and temperament characteristics. Discussion: There was not an association between temperament and chronotype preferences. Chonotype preferences do not affect the severity of depression. Chronotype is not a risk factor for suicide. In assessing the risk of suicide in patients with mild to moderate severity depression without comorbid psychiatric disorders; the clinical characteristics of depression should be prioritized by the clinicians, rather than temperament and chronotype.

    Development and Investigation into the Psychometric Properties of the Troy Sleep Scale
    (Galenos Publ House, 2025) Akinci, Erhan; Bolat, Nurullah; Korkmaz, Sukru Alperen; Toraman, Cetin
    Objective: A unique and comprehensive self-report scale to help assess sleep in Turkish is needed. This study aimed to develop the Troy Sleep Scale (TSS) and perform validity and reliability analyses. Materials and Methods: The study was conducted with 494 medical students and residents. The psychometric properties of the devised scale were evaluated through exploratory and confirmatory factor analyses, Cronbach's alpha and McDonald's omega reliability evaluations, and item analyses based on both classical test theory and item response theory (IRT). The reliability assessment of the TSS was carried out through test-retest, and criterion-referenced validity was employed to provide additional validation. Results: The TSS consists of 11 items with a 3-factor structure with eigenvalues greater than 2. The factors provided information about (I) dysfunction due to sleep problems, (II) affective symptoms due to sleep problems, and (III) sleep quality. The reliability levels of all three sub-factors and overall scale scores were 0.82 and above. The test-retest reliability level had a correlation value of >0.80. The item analyses conducted in line with the IRT proved that the scale items provided a high level of information and functioned together with the answer set. The correlation between the TSS and the Pittsburgh Sleep Quality Index was analyzed for criterion-referenced validity, yielding a correlation of 0.73. Conclusion: The psychometric properties of the TSS indicated that it was valid and reliable, making it suitable for use as a screening test for individuals with sleep-related complaints.

    The associations of temperament, character, anxiety, and specialty choice among sixth-year medical students: a cross-sectional study
    (Kare Publ, 2020) Akinci, Erhan
    Objective: This study aimed to investigate the effects of anxiety, temperament, and character dimensions on the preferences of final-year medical students for postgraduate education. Method: Participants were 161 students in a sixth-year medical class. The primary outcome variables of the study were the preferred main specialty category and branch. Independent study variables were age, gender, perception of the economic situation, place of birth, and State-Trait Anxiety Inventory and Temperament and Character Inventory scores. Results for 151 participants were analyzed. Results: The mean (+/- SD) age of the participants was 23.66 +/- 1.18 years, and 57.6% (n=87) were females. The participants stated that they would choose mostly internal (64.2%, n=97) and surgical (35.1%, n=53) disciplines, while the basic sciences were the least favored (0.7%, n=1). The most popular specialties were psychiatry (9.9%, n=15), orthopedics and traumatology (8.6%, n=13), and physical therapy and rehabilitation (8.6%, n=13). There was no significant difference between state (chi(2)=1.93, p=0.382) and trait (chi(2)=2.31, p=0.315) anxiety levels and the specialty category selections. Harm avoidance (HA), fear of uncertainty (HA2), shyness (HA3), fatigability (HA4), and sentimentality (RD1) scores of students opting for internal medicine were statistically higher than scores for surgical sciences (p<0.05). In addition, the resourcefulness (SD3) scores of the aspiring internists were statistically lower than scores for surgery (p<0.05). Conclusion: Temperament and character have some degree of influence on the choice of specialty, whereas anxiety was shown not to have such an impact. These findings may be helpful to medical educators or career counselors in the specialty choice of medical students.
