Caregiver burden will not only affect the physical and mental health of caregivers but also affect the quality of care provided by caregivers， thus affecting the long-term outcome of patients with schizophrenia. At present， there have been many different assessment tools for caregiver burden of schizophrenia （including general tools and specific tools）. This paper reviews and compares these tools from different aspects such as content， characteristics， and application situations. This paper also analyzed the limitations of these tools and put forward suggestions， with the expectation to guide the assessment and intervention of caregiver burden of schizophrenia in China.
