Knowledge about psychotic disorders, having a positive attitude towards psychotic disorders and having knowledge about the care required is an important aspect for families caring for and handling psychotic disorders (family caregiver) to provide ongoing care. Psychoeducation can facilitate effective treatment and care through understanding family knowledge and attitudes related to caring for people with psychotics. This study was carried out in Sadangmekar village, Cisarua sub-district, West Bandung, for seven family caregivers who treated family members who were experiencing psychotic disorders using alternative medicine or were left without treatment. Psychoeducation lasts for one day and uses methods of providing information (lectures), discussions, and watching videos. The results showed that after attending caregiver psychoeducation gained knowledge about the symptoms of the disorder (100%), the importance of medical and psychological treatment in managing the disorder (100%), the importance of adherence to treatment (100%) as well as the insight that the family has an important role in sustaining care (100%).
