The impact of the COVID-19 pandemic on stress, mental health and coping behavior in German University students - a longitudinal study before and after the onset of the pandemic

Background The COVID-19 pandemic has led to massive restrictions in public and private lives, including a shut-down of face-to-face teaching at universities in Germany. We aimed to examine the impact of these changes on perceived stress, mental health and (study-)related health behavior of students in a longitudinal study. Methods For two timepoints - the year before the COVID-19 pandemic (2019, n = 1377) and the year during the COVID-19 pandemic (2020, n = 1867) - we surveyed students of all faculties at one German university for perceptions and preventive behavior regarding the COVID-19 pandemic using standard instruments for stress, anxiety, depression, and behavior and experience patterns. Results About 90% of students (n = 1633) in 2020 did not have a known contact infected with SARS-CoV-2, while 180 (9.8%) did have one. Only 10 respondents (0.5%) reported an infection with SARS-CoV-2. Wearing masks and washing hands more often were practiced by >= 80% of students. Taking more care about cleanliness (51.8%) and using disinfectants (39.2%) were practiced much less. A higher percentage of female compared with male students and medical/health science students compared with science, technology, engineering, and mathematics students engaged more frequently in specific or nonspecific preventive measures. More than three quarters (77.1%) of all students rated their general health as (very) good. There were no significant differences in general health, stress, and depression between 2019 and 2020 in the students who responded at both timepoints. The distribution of behavior and experience patterns for this group showed a slight but significant difference from 2019 to 2020, namely decreasing proportions of students with a healthy pattern and a risk pattern for overexertion. Students with different behavior and experience patterns showed marked differences in perceptions and reaction to the COVID-19 pandemic as well as psychosocial stress and symptoms, with higher scores for mental health symptoms and lower scores in preventive behavior regarding risk patterns. Conclusion Despite massive alterations to students' lives in 2020, there were only moderate consequences for mental health compared with 2019 in the total student group of this German university. However, identifying students at risk would offer opportunities to foster mental health in relevant subgroups.

Automated summary

The COVID-19 pandemic in Germany led to significant restrictions in public and private life, including halting face-to-face teaching at universities. A longitudinal study was conducted to assess the impact on student stress, mental health, and behavior during the pandemic. Results showed that most students in 2020 did not have known contact with SARS-CoV-2, with the majority practicing mask-wearing and handwashing, but showing less adherence to cleanliness and disinfectant use. Despite the disruptions in 2020, mental health consequences were only moderately different from 2019 for the student population at the university.
