=22 years; age range=18-26) defined by whether they were living with or living without their parents before and after the start of COVID-19, we retrospectively analyzed changes in psychological distress and wellbeing. SMYAs who returned to their parents' homes during post-onset of COVID-19 reported greater mental distress and lower wellbeing, followed by those who were living with their parents both before and after the start of COVID-19. Patterns were not consistent among non-SMYAs, and lower magnitudes of change were seen. There is a significant public health need for mental health services and family education resources for supporting SMYAs in the context of COVID-19 and beyond.
