This scoping review examines how organisations can take a more structured approach to workplace mental health by identifying tools that support implementation. It maps a wide range of instruments across three areas: preventing harm, promoting wellbeing, and responding to mental health issues. Most tools focus on identifying psychosocial risks, with far fewer supporting proactive wellbeing or early intervention. The findings suggest organisations tend to prioritise measurement over action. Overall, the research highlights a gap between assessing mental health and effectively improving it, reinforcing the need for more practical, integrated approaches.
