To advance research on mental health and wellbeing, we need new comprehensive self-report assessments. That’s why we developed DIWeC – The Developmental Inventory of Mental Health and Wellbeing Capacities. It is a new measure of capacities underpinning mental health and wellbeing based on the NDeTeC framework (Dorjee, 2024). If you can, please spare 10 minutes to complete the questionnaire. Validation of this measure will enable further research on the capacities underpinning mental health and wellbeing in the Well Minds Lab and beyond. For example, we have some pilot studies in the works examining links between these capacities, sustainable behaviour and social media polarisation. We are also planning to adapt these measures for children and adolescents. You can help facilitate our research by completing the this questionnaire, we need at least 200 more participants.
