Background: The aim of the research was to examine whether a role-focused self-help course intervention would decrease caregiver stress and distress, and functioning problems, among people who suffer stress because they combine paid work with informal care.; Methods: A pre-registered (NTR 5528) randomized controlled design was applied (intervention vs. wait list control). Participants (n = 128) were people who had paid work and were suffering stress due to their involvement in informal care activities.
