Mental stress during the pandemic was lower in Switzerland than elsewhere
Data from a global study confirms that well-being and mental health suffered during the Covid-19 pandemic. Researchers from the University of Basel and the University Psychiatric Clinics Basel (UPK) have analyzed the Swiss data together with an international group of authors.

The Covid-19 pandemic turned everyday life upside down. In addition to the health and economic consequences, the mental strain on the population has also been a recurrent topic in the media and public.
An international study has now provided figures on how the pandemic affected the quality of life and mental health of people in different countries and regions. A team led by Professor Christian Huber from the UPK and the University of Basel has now analyzed the Swiss data separately. Scientists from other Swiss research institutions and from the international COH-FIT research consortium were involved. The researchers have published their results in the academic journal Frontiers in Psychiatry.
Global data collected
The study is based on standardized surveys that were conducted in parallel in over 40 countries on every continent. In Switzerland, 4037 people reported on their well-being, 3375 people provided information about psychological stress (see methodology box below). The respondents first stated how they currently felt. They were then asked about their well-being before the pandemic. Well-being scores declined over the course of the pandemic. Mental stress, on the other hand, increased. These results confirm the findings of earlier studies, such as the Swiss Corona Stress Study conducted by the University of Basel.
The Swiss population was affected to varying degrees
In an international context, Switzerland is doing well: Well-being and mental health suffered less than elsewhere. We can only speculate on the reasons for this.
“Well-being scores were higher in Switzerland even before the pandemic, and the measures to contain the virus were less drastic than in other countries,” says lead author Christian Huber. He is head of department and deputy clinical director at the UPK Basel and leads the “Psychiatric Care Research” group at the University of Basel.
Knowledge of good healthcare and a good social welfare system may also have had a positive effect, says Huber. The mortality rate may have had an impact too. People in South Africa, Mexico, Belarus and Kazakhstan suffered the most from mental stress.
The analysis of the data also reveals regional differences within Switzerland. In Ticino, the Lake Geneva region and northwestern Switzerland, mental health scores are lower and mental stress scores higher than in the Swiss Plateau and eastern Switzerland.
The researchers suspect that this could be due in part to the fact that the measures taken varied from canton to canton and affected people’s daily lives to different degrees. Geography could also have had an impact: “The fact that social contact was limited and leisure facilities were no longer available could have been more noticeable for people in urban areas than for people in less densely populated regions,” says Christian Huber. Restrictions on cross-border commuting may also have had an impact on perceived stress.
Keeping an eye on mental health
“It is not yet clear how much the pandemic will impact people’s mental health in the longer term. Some effects only become apparent after a longer period of time,” says the expert. He therefore believes it is important to conduct regular surveys to gauge the mental health of the population.
Huber sees prevention as an important starting point. How well people are able to deal with crisis situations has a lot to do with the amount of resources available. “I think it’s important to strengthen the mental resilience of the population and, in times of crisis, to consider how great the psychological strain can be. That’s when support measures are needed.” Huber can imagine, for example, training laypeople to help in a crisis, thereby relieving the burden on the system. “At the same time, there needs to be education in schools and destigmatization of mental illnesses, as has already happened in recent years with depression, ADHD and burnout.”
Further evaluations planned
As the survey was conducted using a voluntary online questionnaire, the data is not representative. “Nevertheless, the results provide important clues,” believes Christian Huber.
Further evaluations aim to show which risk factors played a role in the perceived stress and which coping strategies were particularly successful in dealing with the effects of the pandemic. Christian Huber and his research team expect the results by the end of 2026.
How the data was collected
The Swiss data comes from the international COH-FIT study and was collected online between April 2020 and June 2021. that recorded their subjective well-being (WHO-5) and mental stress (P-score). To measure subjective well-being, the study used the “Well-Being Index” (WHO-5) published by the World Health Organization (WHO), which participants completed. The researchers determined mental health using the “P-score”, which maps five dimensions of mental impairment: anxiety, depression, post-traumatic stress disorder, psychotic symptoms and psychosomatic factors such as sleep or stress.
The participants also reflected on how they felt in the two weeks before the pandemic. The survey was conducted in three waves – April to June 2020 (T1), July to December 2020 (T2) and January to June 2021 (T3) – and in all four national languages. The sample was recruited via media, social networks and partner institutions and was therefore random and unrepresentative. Each person participated only once. The study therefore does not allow any direct conclusions to be drawn about how the quality of life of individuals changed over the course of the pandemic.
