 This proposed randomized controlled trial will test the effectiveness of a problem-solving based bibliotherapy program PSBBP for Chinese family caregivers in schizophrenia spectrum disorders. A repeated-measures, three-group design will be used to evaluate and compare the effects between two treatment groupsPSBBP and psycho-education group and routine outpatient service and family supportcontrol group for 129 randomly selected family caregivers of outpatients with schizophrenia-spectrum disorders over a 12-month follow-up. Primary outcomes include caregivers burden of care, caregiving experiences and coping and social problem-solving skills using validated instruments. Secondary outcomes are patients mental state, functioning, perceived expressed emotion, and re-hospitalization rate. They will be measured at recruitment, one week, and 6 and 12 months following the interventions. Kaplan-Meier survival analysis will be used to analyze the relative risks of re-hospitalizations amongst the treatment and control groups over 12-month follow-up. It is hypothesized that the PSBBP participants will produce significantly better improvements in caregivers perceived burden, caregiving experience and coping and problem-solving skills than those in psycho-education and control groups over 12-month follow-up.
