This study examines the relationship between language use and psychological characteristics of the communicator. The aim of the study was to find models predicting the depressivity of the writer based on the computational linguistic markers of his/her written text. Respondents’ linguistic fingerprints were traced in four texts of different genres. Depressivity was measured using the Depression, Anxiety and Stress Scale (DASS-21). The research sample (N = 172, 83 men, 89 women) was created by quota sampling an adult Czech population. Morphological variables of the texts showing differences (M-W test) between the non-depressive and depressive groups were incorporated into predictive models. Results: Across all participants, the data best fit predictive models of depressivity using morphological characteristics from the informal text “letter from holidays” (Nagelkerke r2 = 0.526 for men and 0.670 for women). For men, models for the formal texts “cover letter” and “complaint” showed moderate fit with the data (r2 = 0.479 and 0.435). The constructed models show weak to substantial recall (0.235 – 0.800) and moderate to substantial precision (0.571 – 0.889). Morphological variables appearing in the final models vary. There are no key morphological characteristics suitable for all models or for all genres. The resulting models’ properties demonstrate that they should be suitable for screening individuals at risk of depression and the most suitable genre is informal text (“letter from holidays”).
The article presents research evidence on psychological impacts of the COVID-19 pandemic on the economically active Czech population aged 18–64 (n = 1603; 365 men and 1238 women) within a one year perspective. The aim is to describe the differences in the reported mental health indicators (anxiety, depression, and distress) for women and men in the four age groups, two groups with different working statuses (continuation of work/interrupted working status), and between two phases of the epidemic (March to May 2020 and September 2020 to February 2021). The results point to elevated scores of negative mental health indicators (anxiety, depression, and distress) in different subgroups. More negative experiences in a pandemic situation were found, especially in groups of women, people under the age of 35, and among people with interrupted working status. The results also indicate a deterioration of symptoms over time during the epidemic.
This study presents the results of a screening focused on the psychological impact associated with the outbreak and further development of COVID-19 pandemic in the Czech population. The aim of the study was to investigate temporal dynamics of psychological impact in a longer period covering phases of the epidemic growth, culmination, decrease, and slow return to a normal lifestyle. The sample of 2716 respondents aged between 18 and 89 years participated in an online survey from March 18th to May 25th, 2020; part of them (typically seniors and others, who had not access to the internet) were assisted in entering the data by trained interviewers. The survey comprised questionnaires capturing emotional states, psychological disturbance, anxiety, and depression. The changes in the scores by time phase were studied for the whole sample and for gender and age groups. The results show that the threat of COVID-19 caused a significant increase in negative emotional experience and in the symptoms of psychological disturbance, anxiety, and depression in the Czech population in time of infection culmination, even when the spread of the pandemic was well controlled, and then a gradual decline over time. The data indicated that the pandemic situation had a more pronounced impact on women and younger adults. The study also showed that in situations of pandemic stress associated with isolation, when isolated people are interviewed about their mental state, their reports on negative experiencing might be significantly reduced compared to direct anonymous self-reports data entry.
