Effectiveness of the Step-by-Step Interpersonal Adaptation Program for Patients with Severe and Chronic Schizophrenia Who Experience Extreme Difficulty in Social Participation (SIAP-SCS): A Retrospective Study

The Step-by-step Interpersonal Adaptation Program for patients with Severe and Chronic Schizophrenia who experience extreme difficulty in social participation (SIAP-SCS) was developed and implemented to achieve social participation for patients who were unable to receive existing psychosocial treatment. The study was conducted as a pilot and retrospective study involving 20 participants. Interviews and medical records were used to evaluate their social participation. After the program, their social participation increased, and the scale scores of social functioning and psychiatric symptoms improved significantly. The results suggest that the SIAP-SCS can help patients with severe and chronic schizophrenia participate in society.
