Methods: This descriptive study was conducted through Google Forms with the involvement of 2,509 immigrants. A descriptive questionnaire, the "IFOMA Post-Migration Post-Traumatic Effect Scale" and the "GADOT Personality Types Determination Scale" were used to collect the research data. Independent samples t-test, one-way ANOVA, and related sample Friedman's two-way analysis tests were used in data analysis. Results: Immigrants were exposed to significant effects in all sub-dimensions of the Post-Migration Post-Traumatic Effect Scale. Experiencing post-traumatic stress was found to be significantly related to the research parameters, which, respectively, are gender, age, marital status, educational background, legal status, years of living in the current country, employment status, ethnicity, Turkish language proficiency, and postmigration psychological problems (p < 0.05); 42.8% of the immigrants had the Type 9 personality, and all personality types were affected by the Psychological Affection, Physical Affection, Anxiety, and Social Adaptation sub-dimensions, respectively (p < 0.05). Conclusion: By analysing the impact of migration-induced trauma on immigrants within their society, it can be recommended to implement initiatives specific to immigrants' personality traits and to carry out protective/preventive projects that will minimize immigrants' exposure to trauma and encourage their participation in social adaptation processes.

Materials and Methods: An online questionnaire was performed to evaluate 713 medical school students. The questionnaire included the subsections of sociodemographic data, items evaluating selected features, Generalized Anxiety Disorder-7 (GAD-7) Scale and Coping Styles Scale Brief Form (The Brief COPE). Results: Of the 713 participants, 285 (39,97%) were normal, 261 (36,61%) were mild, 123 (17,25%) were moderate, and 44 (6,17%) had severe anxiety. 167 (23,42%) of the participants had GAD-7 scores ≥ 10, so they had a "clinically significant anxiety" and these individuals needed clinical evaluation in terms of GAD. Being female and younger was associated with significant clinical anxiety. More adoption of the ineffective coping strateg...

METHODS: Pregnant women who were followed up in our gynecology outpatient clinic were evaluated during their admissions between November 15, 2020 and February 15, 2021. This cross-sectional study analyzes prospectively collected data from a university hospital. Inclusion criteria were those being at risk of pregnancy and between the age of 18 and 45 years, while exclusion criteria were mental retardation and the presence of serious psychiatric illness. The study included 140 participants. Sociodemographic and pregnant attitudes-behaviors data form, State-Trait Anxiety Inventory, Coping Styles Scale Brief Form (Brief-COPE), and Multidimensional Scale of Perceived Social Support were used to collect data. RESULTS: Participants had high anxiety levels (State-STAI: 40.32±9.88; Trait-STAI: 42.71±7.32) and high prevalence of probable clinical anxiety [State-STAI: 84 (60.0%); Trait-STAI: 92 (65.7%)]. The fact concerning the transmission of the coronavirus disease 2019 to the baby during pregnancy/birth, extent to which coronavirus disease 2019 pandemic prevents regular pregnancy checkups, and family subgroup-Multidimensional Scale of Perceived Social Support predicted state probable clinical anxiety. Use of disinfectants predicted trait probable clinical anxiety. Employment status predicted state/trait probable clinical anxiety. The existence of trait probable clinical anxiety was significantly associated with behavioral disengagement and substance use which are considered ineffective coping styles. Participants without trait probable clinical anxiety had significantly more adopted positive reinterpretation, one of emotion-focused coping styles. CONCLUSION: Based on our results, the concern of the transmission of the coronavirus disease 2019 to the babies during pregnancy/birth may be the main factor influencing anxiety among high-risk pregnant women.

The major obstacles to this endeavor have been the severity and the delay from time of exposure to the traumatizing events. To avoid these issues, EEG and clinical examinations of 18 healthy, drug-free subjects were performed 2 weeks after an earthquake occurred in Turkey in 1999. It was found, for the first time to our knowledge, that EEG parameters can predict startle response in acute stress reaction correctly in 100% of the cases. EEG measures of the reactivity to eyes opening were especially important in this regard.

The aim of this study is to evaluate the prevalence of positive screening of the MDQ among general population and to investigate the associated risk factors.In this cross-sectional study, the sample was randomly selected from household data to represent the city population. A total of 432 participants were asked to fill in MDQ, CAGE (cutting down, annoyance by criticism, guilty feeling, and eye-openers) questionnaire, which consists of four clinical interview questions proven to aid in the diagnosis of alcoholism, and clinical and sociodemographic data form.The Cronbach’s alpha value of our current study was 0.813 for MDQ.

Whereas, positive reinterpretation, one of the emotional focused coping styles was a predictor in reduction of significant clinical anxiety. Also more frequent exposure to social media and sleep disturbances were the predictors of significant clinical anxiety in the healthcare staff. Conclusion: Our results have emphasized the factors that should be taken into account and application of coping styles that may be functional in protecting mental health of the healthcare workers in their struggle against a huge disaster affecting worldwide societies.

The estimated prevalence rate of bipolar disorders varied between 0.3 and 13.4% according to different cutoff values. Multivariate logistic regression models showed that the presence of possible alcohol addiction, shift work history, and body mass index (BMI) were statistically significant predictors of MDQ positivity. The prevalence of MDQ positivity found is similar to studies in literature. Keeping in mind that psychometric properties of the MDQ, positive screen results should be cautiously interpreted due to the presence of other risk factors and comorbidities.

In this study we aimed to evaluate the personality traits of epileptic patients and compare them healthy controls by using Cloninger’s Temperament and Character Inventory (TCI).

The data were analyzed with regard the group differences with t test (parametric condition) or Mann- Whitney U tests by using computer program.
