Informal carers are increasingly involved in supporting people with severe and enduring mental health problems, and carers' perceptions impact the wellbeing of both parties. However, there is little research on how carers actually make sense of what their loved one is experiencing. Ten carers were interviewed about how they understood a loved one's psychosis. Data were analysed using a hermeneutic-phenomenological approach. Three themes described the carers' effortful quest to understand their loved one's experiences while maintaining their relational bonds.
