Methods
mental disorders
A one-group pretest–posttest trial was conducted using a mixed-method design for 45 individuals with mental disorders in Japan. Outcome data were collected at three time points: baseline, post-intervention, and one month after program completion. Mixed models for repeated measures (MMRM) were used to examine changes over time in the Rosenberg Self-Esteem Scale (RSES), Recovery Assessment Scale (RAS), Herth Hope Index (HHI), and the original items. Group interviews were conducted for process evaluation.
