Why an evidence-driven approach is the best way for businesses to support workplace mental health

Mental health has never been higher on the agenda for businesses. It is easy to see why, as even prior to COVID-19, anxiety and depression were estimated to cost the global economy over $1 trillion every year in lost productivity. The exodus from offices in 2020 has presented further challenges and raised big questions about future ways of working.

With the global corporate wellness market forecast to reach $66 billion by 2022, many employees will be familiar with the range of workplace mental health initiatives that a growing number of businesses offer their staff – from yoga and mindfulness to flexible working. But despite the prevalence of different approaches, we’re yet to understand what works, for who, and why.

The absence of a deep and robust evidence base for approaches to supporting workplace mental health is a problem and can lead to well-intentioned businesses making critical and sensitive decisions in the dark. At best, such interventions are working and we just don’t know why or, at worst, they could be causing harm to workforces.

Data and evidence are familiar ground to businesses, used to make strategic decisions and improve performance – from pinpointing new opportunities to measuring impact and effectiveness of programmes. When it comes to finding the most effective approaches, there is an immediate need for businesses to apply this evidence-led mindset, collaborate with others to share learnings and put science to work in support of mentally healthy workplaces.

Wellcome, in partnership with the World Economic Forum, is publishing new research on workplace mental health: Putting Science to Work – Understanding What Works for Workplace Mental Health. Ten global research teams reviewed the evidence behind promising approaches for addressing anxiety and depression in the workplace, with a focus on younger workers.

These reviews show that there are some things that businesses can learn based on the existing evidence. To share a few examples:

The research also highlights how much we still don’t know about what works for different people and in different contexts. For example, many research teams commented on the lack of data about younger workers’ mental health. The evidence available also widely differs between geographies – for example there is significantly more research on mindfulness in high-income countries compared to low and middle-income settings, with particularly big gaps in the tourism and hospitality sectors. Comparison across different studies was also difficult, as approaches to measuring mental health in workplaces are not standardized.

The complexity of workplace mental health issues requires complex and considered solutions – there is no quick fix or “one size fits all” approach. We are still a long way off knowing what works and later this month, Wellcome will be launching a second research commission to look at the evidence behind a wider range of approaches. Through this commission we hope to broaden our understanding of the existing evidence and we’ve been engaging with the business community to find out what approaches they might like to see prioritized in this research.

However, crucial evidence gaps will remain unfilled unless businesses collaborate with researchers to fully understand the impact of their efforts and share their learning. This is the only way that businesses can guarantee that their investments and good intentions are making a difference for their employees and their business.
