Objectives：Among the various schizophrenic symptoms, negative symptoms are particularly disabling as the disorder continues with time. This study aims to evaluate the effect of clinical art therapy on negative symptoms in patients with schizophrenia. Methods：Twenty patients, 10 in a case group and 10 in a control group, admitted to Severance mental health hospital diagnosed with schizophrenia participated in this study. Case group participated in an 18-session clinical art therapy program. Patients’ symptoms were evaluated with Positive And Negative Symptom Scale (PANSS) before and after the program. Anhedonia, one of the negative symptoms of schizophrenia, was evaluated using an anhedonia rating scale. Qualitative analysis of Landscape Montage Technique (LMT) drawn by patients at session 1 and session 18 was done to compare the change of drawing contents. Participation rate and attitude were also evaluated. Results：There was no statistical significance in total negative subscale score change (p=0.063). However, among seven negative symptom subscales, blunted affect (p=0.028) and poor rapport (p=0.028) showed a statistically significant difference. Anhedonia rating scale also showed significant difference (p=0.036) where physical subscale was significantly different (p=0.048) but social anhedonia was not (p=0.115). Comparison of LMT before and after the program showed positive change in colors, space, and content. Participation attitude and sociability also improved. Conclusion：Clinical art therapy may help patients with schizophrenia in improvement of negative symptoms. (Journal of The Korean Academy of Clinical Art Therapy 2008;3(2):89-94)
