This paper is a basic study for applying Landscape Montage Technique(LMT) to art therapy. The purpose of this study is to examine the differences in the reaction characteristics of LMT between the individual conduct and the collective conduct in LMT. For this study, 103 elementary students (46 male, 57 female) were asked to participate in LMT twice from March to June 2011, in order to target the same group by the individual conduct and the collective conduct. Data analysis was performed using Cohen\'s Kappa value and cross tabulation. The results are as follows: First, reliability appeared to be in the range of .773 to 1.0. Secondly, there are 5 interpretation criteria that show a significant difference. These include: integration, reality of figures, color fit in total index, mountain figures, and stone use in item index. In conclusion, it was found that LMT can be an effective treatment tool for schizophrenia patients and can also be used as a diagnostic tool by the collective conduct, especially in regards to quantitative research.
