The study aimed to examine the effects on emotion expressivity, illness engulfment, and empathy by applying group arts therapy using play to schizophrenic inpatients. The subjects were 12 inpatients with schizophrenia in H hospital (6 experimental groups and 6 control groups). Twelve sessions of group arts therapy using play were conducted twice a week and 50 minutes per session. In order to assessment, Berkeley expressivity questionnaire, Korean version of modified engulfment scale, and Basic empathy scale were conducted. As a result, first, group arts therapy using play had a significant effect on improving the factors of positive and negative expressivity among the emotional expressivity of schizophrenic patients. Second, group arts therapy using play was effective in reducing the factors of impact on self-concept among illness engulfment of schizophrenic patients. Third, group arts therapy using play had a positive effect on the factor of affective empathy among empathy of schizophrenic patients.
