Patient-initiated violence may pose a significant risk to the strength and longevity of informal caregiving relationships in psychosis. We aimed to assess caregiver reports of patient-initiated violence in early psychosis and to examine the relationship between violent incidents and appraisals of caregiving, perceived mental wellbeing in caregivers and Expressed Emotion (EE) in the caregiving relationship. Eighty psychosis caregivers were recruited via Early Intervention (EI) psychosis services in London, United Kingdom.
