Introduction: The COVID -19 pandemic significantly impacted the mental health and wellbeing of healthcare workers worldwide. This study examined the prevalence and predictors of self -reported mental health problems, specifically depression, anxiety, stress, and burnout among government healthcare professionals in Brunei Darussalam during the second and subsequent waves of the pandemic. Materials and Methods : A cross -sectional online survey was distributed to all government healthcare workers employed by the Ministry of Health in Brunei Darussalam. The survey collected sociodemographic information and applied two validated tools: the Depression Anxiety Stress Scale 21 -item version (DASS -21) to assess the depression, anxiety, and stress, and the Oldenburg Burnout Inventory (OLBI) to measure burnout. Results : Of 1,759 invited healthcare workers, 704 responded (response rate 40.0%). The prevalence of common mental health problems and burnout were 32.4% and 71.7%, respectively. Older age was protective against common mental health problems. Performing clinical duties outside one's training scope, and direct involvement in managing COVID -19 patients were significant predictors of common mental health problems. Expatriate staff had significantly lower odds of burnout compared to Bruneian nationals. Shift work and additional administrative duties independently predicted burnout. A history of mental health problems and difficulty accessing mental health support were strongly associated with both outcomes. Conclusions : This study identified a substantial burden of depression, anxiety, stress, and burnout among government healthcare professionals in Brunei Darussalam, with distinct vulnerable subgroups. These findings highlight the need for targeted mental health interventions, improved access to support services, and systemic workplace strategies to safeguard the wellbeing of the healthcare workforce.
