Much of psychology’s most valuable data is already out there — forgotten on old servers. Our new project unites nine European studies and over 50,000 participants to show how harmonizing existing data can unlock fresh insights into mental health and resilience, without starting from scratch.

When global health emergencies hit, healthcare workers face intense pressure that can strain their mental health. Our study of over 2,000 workers reveals most respond with resilience — their stress levels match the challenges they face.

During a five-week research visit in Halifax, I explored how resilience intersects with cultural and social contexts. Working with diverse communities and experts, I discovered that protecting mental health requires balancing individual strengths with structural realities. This experience reinforced that resilience is deeply connected to, and cannot replace, social justice.

Our reactions to events are shaped more by how we interpret them than by the events themselves. A positive appraisal style—tending to view situations realistically or optimistically—helps reduce stress and protects mental health. New questionnaires now allow researchers to measure this style, advancing our understanding of resilience and its role in well-being.
