Background: This study aimed to evaluate the psychometric properties of the Coronavirus Worry Scale and related factors with COVID-19 worry.
Methods: The data were collected through online survey from 846 participants and final sample was 804 after excluding missing data. The psychometric properties of the Turkish Coronavirus Worry Scale were assessed through exploratory factor analysis, confirmatory factor analysis, internal consistency reliability analysis, and Pearson product moment correlation with other psychological constructs.
Objective: We aimed to assess the validity and reliability of a Turkish adaptation of the Glasgow Sleep Effort Scale (GSES).
Methods: We randomly divided the data into two: one set (n = 374) was used for exploratory factor analysis (EFA) and the other (n = 373) for confirmatory factor analysis (CFA). The psychometric properties were assessed using the item response theory approach.
Objective: To determine relationship between the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) on cognitive impairment and brain derived neurotrophic factor (BDNF), glial cell derived neurotrophic factor (GDNF) levels in treatment resistant depression (TRD).
