Theory Based Integrated Program on Medication Adherence Among Community Dwelling Schizophrenia

This clinical trial aims to evaluate the effectiveness of the theory-based integrated program in promoting medication adherence in patients with schizophrenia. The purpose of this study are: * To explore the effectiveness of the theory-based integrated program in promoting community-based schizophrenia patients' adherence to medication(like :motivation, attitude and behavior) * To explore the effectiveness of the theory-based integrated program in improving the psychiatric symptoms of patients with schizophrenia in the community. Participants (the experimental group) received routine home visits from psychiatric mental nurses, including drug administration, drug side effects and symptom management, life care, and the theory-based program provided by the researcher(treatment as usual + the theory-based integrated program). The comparison group: received routine home visits from psychiatric mental nurses, including drug administration, drug side effects, and symptom management, life care,(treatment as usual).

Members of the experimental group received routine home visits, plus a 1-hour the theory-based program intervention 12 times in the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th, 21st, and 23rd weeks, and each patient received a total of 12 hours of intervention. The control group received routine home visits by psychiatric mental nurses, and the nurse provided patients with answers to questions about medications or care and handling of life events. The visits and intervention time frequency were the same as those in the experimental group. Both groups were received baseline (T0), after the 6th hours intervention (T1) and 12th hours intervention by nurses to collect data on the main outcome variables: adherence to medication, mental symptoms, motivation to take medication, and attitude towards medication.
