Purpose: the purpose of this study is to evaluate the effect of social adjustment training program on chronic schizophrenia patients` self-esteem and interpersonal relations so as to suggest evidence which could be applied in a clinic situation. Methods: The study was designed with nonequivalent control group non-synchronized design. The subjects of this study were 31 hospitalized chronic schizophrenia patients in J. sanatorium for mental disease in Busan. An experimental group of 16 and a control group of 15 patients participated. This study was carried out from April 20, 2002 to July 6. 2002. The program that used for social adjustment training was based on "Modern Mental Health & Community PART Ⅰ (1996)"and "Community based Mental Health Nursing Programme for Rehabilitation of Long-term Psychiatric Patients(1998)" and reconstructed by author. The program was performed 6 times, once a week. The effectiveness of the program was investigated through Self-Esteem Scale(SES) and Relationship Change Scale (RCS). The tool for self-esteem was made by Rosenberg in 1965. It was translated by Cheon, Byung Jae. The tool for interpersonal relations was made by Schien and Guerney. It was translated by Moon, Seon Mo(1980) and modified by Cheon, Suk Kyun(1994). The collected data was analyzed by SAS 8.2 program with x²- test and t-test. Result: The results of the study were as follows : 1. The first hypothesis "The experimental group which received the social adjustment training program would score higher from self-esteem scale than control group", was supported(p= .0005). 2. The second hypothesis "The experimental group which received the social adjustment training program would score higher from interpersonal relations scale than control group", was supported(p= .0145). Conclusion: From the above results, social adjustment training program had a positive effect on chronic schizophrenia patient`s self-esteem and interpersonal relations.
