Problem-solving-based Bibliotherapy Program for Family Caregivers

Family caregivers of people with psychotic disorders are confronted by a various physical, psychosocial and financial hardships. This can adversely affect family members' caregiving experiences, psychological distress, general well-being, and family relationships or emotional involvement, which in turn may contribute to a greater risk of patient relapse and non-recovery. While family psycho-education and mutual support groups are effective in reducing caregivers' burden of care, these approaches usually require regular meetings and encounter difficulties in extensive training of group leaders/facilitators and engaging participants to actively share their caregiving experiences due to time inconvenience and fear/inability of expression of feelings. By virtue of the above, an alternate model of self-help program in book form named bibliotherapy, which is a guided reading and self-practice program with problem-solving training facilitated by a psychiatric nurse, has recently demonstrated evidences in clinical trials for families of depressive and psychotic patients by the research team, and other researchers. In phase 1, a pilot randomised controlled trial with repeated measures, parallel-group (2-arm) design will be carried out at one psychiatric clinic. This pilot trial aims to evaluate the effects between the treatment group (i.e., a problem-solving based self-learning program) and routine outpatient service (control group) for 116 randomly selected family caregivers of outpatients with recent-onset psychosis over a 6-month follow-up. The study outcomes include the caregivers' burden of care, caregiving experiences, and problem-solving abilities, and the patients' mental state, functioning, and re-hospitalization rates. They will be measured at recruitment, one week, and 6 months following the interventions. Another pilot controlled trial will recruit 116 families of people with first-episode psychosis attending follow-up at two regional psychiatric outpatient clinics in Hong Kong. Participant will be randomly selected in equal proportion from the two clinics under study and after baseline measures, the participants will be randomised to the treatment (i.e., the Chinese version of the original manual of bibliotherapy program) or the routine care. They will also be measured with the similar outcomes at the above pilot study at recruitment, one week, 6 months, and 12 months post-intervention. In phase 2, a 3-arm randomized controlled trial will be conducted to test the effectiveness of the problem-solving based bibliotherapy program (PSBBP) for Chinese family caregivers in early stage of psychotic disorders. A repeated-measures, three-group design will be used to evaluate and compare the effects between two treatment groups (PSBBP and psycho-education group) and routine outpatient service and family support (control group) for 198 randomly selected family caregivers of outpatients with psychotic disorders over a 24-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 12 and 24 months following the interventions. 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 24-month follow-up. Focus group interviews will be conducted after the first post-test with 20 caregivers (10 participants per group) in both treatment groups. Their data will be content analyzed to identify their perceived benefits, limitations and difficulties encountered and therapeutic ingredients of the two programs.
