When compared with those in the control (usual care) group, participants in the AT group are expected to demonstrate significant improvements immediately and at three, six and 12 months after completion of the intervention in the following aspects:
1. level of adherence to antipsychotic medication,
2. rate and length of psychiatric hospital readmission,
3. mental status,
4. insight and attitude into illness and treatment, and
5. level of functioning.
The primary outcomes are level of antipsychotic medication adherence, re-hospitalization rates and mental status; and the patients' drug attitude will be the mediating factor of the AT.
