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.

Background Medical education has a reputation for being demanding and stressful. However, longitudinal surveys across the whole course of study considering risks and resources are rare. Methods For the evaluation of stress and coping we administered the standard instruments Perceived Medical School Stress Scale (PMSS), Hospital Anxiety and Depression Scale (HADS), Work-Related Behavior and Experience Patterns (AVEM), Maslach Burnout Inventory (MBI), and a short form of the Coping Orientations to Problems Experienced Scale (Brief COPE) in three consecutive cohorts of medical students (N = 377) at one German university. Students were surveyed at the beginning of their studies (t0) and again during each consecutive summer semester (t1-t6). Results Stress and symptoms of anxiety and depression increased in the first two years of medical studies but decreased again towards their end. Consistently, freshmen medical students presented with a large proportion of the healthy pattern at t0 (56 %) that decreased to 30 % at t2, and increased up to 44 % at t6. Correspondingly, the proportion with the burnout-related risk pattern B increased from 9 to 16 % at t2, again decreasing to 7 % at t6. Over the whole course of study there was an almost continuous increase of the unambitious pattern S from t0 13 to 40 % at t6. Characteristic differences especially between the healthy pattern and the risk patterns regarding stress, mental health symptoms and coping were observed. Female students showed a higher vulnerability for stress, anxiety and depression as well as lower proportions with a healthy pattern, and higher proportions with risk patterns for overexertion and burnout. Conclusions The development of stress, symptoms and behavior and experience patterns especially in the first two years, demonstrating increasing study-related stress in the preclinical years, as well as the high proportion with an unambitious pattern at the end of the course of study emphasize the need for prevention and health promotion at both the individual and contextual levels.

Studying can be very stressful leading to a decreased academic efficacy. In this exploratory longitudinal study, we analysed a wide range of students’ leisure activities and their effects on students’ academic efficacy. Further, we identified the personality types of students who choose specific leisure activities as a strategy to stress reduction and determined how the use of leisure behaviours affects academic performance among students with different personality types. Students were asked about their personality (Neo-FFI), leisure time behaviour (self-generated items), and academic efficacy (MBI-SS) at three measurement points. Multivariate regression analyses were applied to estimate the moderation effects. In total, 331 students were included in the study. Social activities were found to have a direct effect on academic efficacy. The students’ personality moderated the effects of leisure behaviour on efficacy, suggesting a negative effect on academic efficacy for some personality traits. Since our results suggest that the effectiveness of stress management through the use of leisure behaviour depends on the students’ personality, universities offering stress management services should pay attention to precise targeting to attract the specific students who might benefit the most from the offered services.
