Kim and Jung: An Integrative Literature Review of Quality of Life Intervention Programs for Patients with Schizophrenia



The purposes of this study are to review the literature on quality of life intervention programs and to recommend further research and clinical considerations to improve the quality of life among patients with schizophrenia.


Three electronic databases - PubMed, CHINAHL and RISS - were searched using the search terms of “schizophrenia” AND “quality of life” AND “intervention*” OR “program*.” The search was limited to studies published in English and Korean.


Ten studies were selected for the final analysis and evaluated in terms of contextual and methodological quality. The 10 studies consisted of 5 randomized controlled trials, 4 quasi-experimental studies, and 1 case report. The selected studies utilized an educational program, art and music therapy, physical activity therapy, and community-based integrated programs to alleviate psychological symptoms and showed effectiveness in improving quality of life.


Interdisciplinary interventions and programs using multiple components reduced psychological symptoms and improved the quality of life of patients with schizophrenia.
