The study aimed to test whether group reminiscence intervention for inpatients with schizophrenia is feasible, acceptable and preliminary effective. The effect of the intervention was evaluated on cognition, communication, and social function. Phase I was a multi-phase parallel study (n=38). The purpose of the study was to assess feasibility and preliminary efficacy by conducting an 8-week intervention with the participants. The study employed a single-group pretest-posttest evaluation. Phase II evaluated acceptability and performed a thematic analysis of semi-structured interviews conducted by a purposively selected subsample (N=8).
