About

In this study, we are going to investigate quantitative and qualitative natures of appetite and eating-behavior changes induced by atypical antipsychotics, i.e., risperidone, olanzapine and aripiprazole, in schizophrenia patients.

Full description

This is an observational study. 2 Self-report questionnaires assessing changes of appetite and eating behaviors after medication are applied to patients who have been receiving one of the three atypical antipsychotics. We are going to compare changes of appetite and eating behaviors after medication between three atypical antipsychotics and investigate the association between changes of appetite and eating behaviors and changes of weight after medication.
