The purpose of the current study was to identify latent profiles of COVID-19 fear, depression, anxiety, stress, mindfulness, and resilience among university students. A total of 506 university undergraduate and graduate students from various universities were recruited through online platforms in Turkey. Data were collected utilizing self-report scales and were analyzed utilizing latent profile analysis. Results indicated significant relationships among COVID-19 fear, depression, anxiety, stress, resilience, and mindfulness. A three-class solution was adapted to fit the current data. Findings revealed that 46% of the participants were classified into the high COVID-19 fear and medium psychological symptoms profile. Also, 38% of the participants were identified as low psychological symptoms and high mindfulness and resilience. Additionally, 16% of the participants were classified as high COVID-19 fear, psychological symptoms and low mindfulness and resilience. Female gender was positively associated with COVID-19 fear, depression, anxiety, and stress. Life satisfaction and social support were positively associated with the mindfulness and resilience, and were negatively related to COVID-19 fear, depression, anxiety, and stress.
ObjectiveTo date, the affective temperamental characteristics of adults with attention-deficit hyperactivity disorder (ADHD) have not been studied. The aim of this study is to explore those temperamental characteristics for adults diagnosed with ADHD as measured by the TEMPS-A and then to compare those results with results for individuals diagnosed with bipolar disorder (BD) and with healthy controls.MethodsForty adults with ADHD, 40 patients with BD, and 40 healthy controls were enrolled in this study. The groups were matched by age and gender. All patients were assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID I), the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, the Young Mania Rating Scale and the Wender Utah Rating Scale. Subjects' temperamental characteristics were examined using the Turkish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A).ResultsTen subjects (25%) in the ADHD group and 15 subjects (30%) in the bipolar group had at least one dominant temperament. There was no identifiable dominant temperament in the control group. Compared to the control group, the ADHD group scored higher than other groups on all domains of the TEMPS-A: depressive cyclothymic, irritable and anxious. However, the hyperthymic domain was not higher for this group. Adults with ADHD scored higher on the irritable temperament scale as compared to the BD group. The ADHD and BD groups had similar mean scores for each of the other four temperaments.ConclusionThe adults diagnosed with ADHD in this study had different temperamental characteristics from the control group, and these temperamental characteristics were similar to those of the bipolar patients. Recognizing the role of temperamental characteristics in adults with ADHD may increase our understanding of ADHD.
Objective : Somatic Symptom Disorder (SSD) is a reflection of medically unexplained physical symptoms that lead to distress and impairment in social and occupational functioning. SSD is phenomenologically diagnosed and its neurobiology remains unsolved. Approach : In this study, we performed hyper-parameter optimized classification to distinguish persistent SSD patients and healthy controls by utilizing Functional Near Infrared Spectroscopy via performing two painful stimulation experiments, Individual Pain Threshold (IND) and Constant Sub-Threshold (SUB), that include conditions with different levels of pain (INDc & SUBc) and brush stimulation. We estimated dynamic functional connectivity time series by using sliding window correlation method and extracted features from these time series for these conditions and different cortical regions. Main Results : Our results showed that we found highest specificity (85%) with highest accuracy (82%) and 81% sensitivity using SVM classifier by utilizing connections between Right Superior Temporal-Left Angular Gyri, Right Middle Frontal (MFG) -Left Supramarginal Gyri and Right Middle Temporal -Left Middle Frontal Gyri from INDc condition. Significance : Our results suggest that fNIRS may distinguish subjects with SSD from healthy controls by applying pain in levels of individual pain-threshold and bilateral MFG, left Inferior Parietal and Right Temporal Gyrus might be robust biomarkers to be considered for SSD neurobiology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
