Objective: In this study, we investigated the effects of a mindfulness-based family psychoeducation (MBFPE) program on the mental-health outcomes of both caregivers and young adults with first-episode psychosis with an onset in the past three years through a multi-site randomized controlled trial. We also studied the outcomes of three potential mediating effects of interpersonal mindfulness, expressed emotions, and non-attachment on the program. Method: We randomly assigned 65 caregivers of young adults with psychosis to MBFPE (Psychosis has significant detrimental effects on the physical and social functioning of individuals [While young adults experience the symptoms of psychosis, they also face tremendous stigma. Accordingly, the caregivers of such young adults are likely to experience emotional burden, depression, and anxiety. The caregivers of young adults after the first onset of psychosis often struggle with performing the roles of caregiver and parent of the affected young people and maintaining the harmony of the family unit [The expressed emotions (EEs) of caregivers and the relationships between EEs and the prognosis of psychosis have been documented [When exploring the manifestations of EEs, it should be noted that the context and cultural norms should also be considered. Young adults lacking self-care abilities to some extent and over-involvement from their caregivers are quite common. In Asian countries, such as China, Japan, and India, strong family ties and connectedness might mean that the caregivers’ concern is likely to be converted into over-involvement [
