1 in 3 South Africans will experience depression, anxiety or a substance use disorder in their lifetime. Yet for most people, the path to recognising it, let alone seeking help is long, stigmatised, and inaccessible.
A team of researchers at the University of the Witwatersrand is putting in all that work in changing that, Dr Tasneem Hassem and Prof Sumaya Laher, from the Wits School of Human and Community Development, have developed MDDSA; the first validated online depression screening tool designed specifically for the South African context.
The urgency behind this work is backed by their own research. A Wits study led by Dr Joel Msafiri Francis found that nearly half of undergraduate students surveyed screened positive for probable depression; a striking finding that underscores just how widespread and under-addressed this crisis is, particularly among young people.
What makes MDDSA different?
Most existing screening tools were developed for and validated in high-income, English-speaking populations. South Africa has its own unique social, economic, and linguistic landscape and depression presents and is experienced within that context. MDDSA was built with that reality in mind.
The tool is built on the CESD-R scale, adapted and validated for local use over four years of rigorous PhD research. It consists of 19 questions about how a person has felt over the past two months and takes approximately 15 minutes to complete. Upon finishing, users receive instant, empathetic feedback indicating their risk level; low, medium, or high, along with resources and contact details for professional support.
It's free. It's online. And it meets people where they are.
The innovation was selected from a competitive field in the Prospector@Wits programme run by Wits Enterprise, earning R100 000 in seed funding to advance its commercialisation a validation not just of the technology, but of its potential for real-world impact.
Why this matters now
South Africa faces a profound mental health treatment gap. Awareness is low, stigma is high, and access to professionals is limited. An accessible, culturally relevant, and clinically validated screening tool is not a luxury it's an essential first step in getting people the help they need.
