Dr Herkulaas Combrink, a senior lecturer in the Faculty of Economic and Management Sciences (EMS) at the University of the Free State (UFS), is representing the university in a new international research project that aims to improve how evidence is used in public health policymaking.

Dr Combrink, who is also a co-director of the Interdisciplinary Centre for Digital Futures (ICDF), has been selected as one of the principal investigators in a newly funded project supported by the UK’s International Science Partnerships Fund under the Evidence-Informed Policymaking Programme. Running from April 2025 to March 2026, the project – titled Integrating Evidence for Contextualised Public Health Policy: Lessons from South Africa – explores how different types of evidence can be used more effectively in shaping public health policy. The international collaboration includes researchers from the Centre for Philosophy of Epidemiology, Medicine and Public Health, which is a collaboration between Durham University and the University of Johannesburg; as well as Durham’s Centre for Humanities Engaging Science and Society.

 

From the Free State to global impact

For Dr Combrink, being part of this collaboration highlights the important work being done in the faculty and ICDF that is reaching beyond borders. 

“It’s important to showcase the impact we are making from the Free State that leads to global outcomes,” he said.

The project aims to evaluate an evidence mapping framework to determine how model-based projections and social listening reports can be more effectively integrated and contextualised for policymaking.

“These are two very different data types,” he explained. “The value lies in demonstrating how to apply the framework to different contexts for evidence-based mapping.”

Dr Combrink brings extensive expertise to the team, having worked on both disease modelling and risk communication during South Africa’s COVID-19 response. He was involved in national and provincial social listening initiatives, and used high-frequency social media data to track the spread of misinformation, often referred to as the ‘infodemic.’ 

“We’ve built up enough data within ICDF and EMS to support this study,” he noted.

The goal is not just theoretical. A key outcome of the project is engaging directly with policymakers to refine modelling and risk communication strategies for future pandemics. 

“This will help us to engage with the various departments of health to assist with improving modelling and risk communication work for better social behavioural change,” he explained.

According to Prof Brownhilder Neneh, Vice-Dean for Research and Internationalisation in the EMS faculty, the project reflects the faculty’s growing global presence. 

“Dr Combrink’s participation is a testament to the calibre of scholarship within the faculty,” she said. “It positions EMS as a key contributor to shaping policy and practice with societal impact.”

She added that the collaboration aligns well with the faculty’s vision for global partnerships that are rooted in local relevance.

“By focusing on contextualised evidence for policymaking, this project reflects our commitment to relevance, engagement and global partnership,” she said.

 

What comes next

Over the project’s 12-month timeline, the team will deliver:

• a case study analysis of modelling and social listening during South Africa’s COVID-19 response;
• an extended evidence mapping framework tailored to diverse evidence types;
• policy briefs and practical tools for public health practitioners; and
• a hybrid international workshop in late 2025 bringing together researchers, policymakers and health professionals to test and refine these outputs.

Emotional health of vulnerable children needs urgent intervention
2014-02-04



In South Africa, thousands of children under the age of 18 are orphaned as a result of HIV/Aids. Experts are worried that these orphans and vulnerable children will experience serious socio-emotional problems and behaviour disorders, should urgent intervention programmes not be implemented urgently.

A study was undertaken by the Centre for Development Support at the UFS, in conjunction with Stellenbosch University and the Houston University in America. The research found that in the Free State province alone, about 15% of orphans and vulnerable children showed signs of psychiatric disorders. Almost half of the children in the study showed signs of abnormal or maladjusted behavioural functioning.

The research team believes that the South African government and the numerous non-governmental organisations put too much emphasis on the physical needs of orphaned and vulnerable children and that their socio-emotional or mental wellbeing receives very little attention.

The nominal financial grant is a welcome relief for some of the needs of this risk group. Researchers are worried, though, that the lack of reliable and culturally-sensitive diagnostic methods for the early detection of psychiatric disorders may pose a challenge when the children reach puberty.

The current study is focusing on the detection of emotional behavioural problems even before adolescence. Questionnaires were distributed across the Free State at clinics, schools and non-governmental organisations dealing with these children. The questionnaires enabled researchers to establish the children's socio-emotional needs.

"Overcrowding in houses where orphans and vulnerable children often live is directly linked to poor socio-emotional health in children," says Prof Lochner Marais from the Centre for Development Support. "The state institutions offering programmes for orphans and vulnerable children overemphasise the physical and/or financial needs of these children. The programme provides, for example, food for the children, grants for the [foster] parents, assistance with school clothes and ensures clinic visits for the children. Of these, only the supply of food has a direct impact on the improved mental health of children."

The study provides, for the first time, a profile of the state of mind of this group, as well as the emotional impact of HIV/Aids – an "urgent matter" according to Dr Carla Sharp from the University of Houston's Department of Psychology. According to Dr Sharp, much more could be done to assist foster parents in addressing the emotional needs of these children. The early detection of behavioural disorders should be the key in intervention programmes.
