This paper addresses the application of Landscape Montage Technique(LMT) as an emotional assessment
tool for adolescents. The study subjects are 449 high school students(268 male, 181 female) between the first
and second levels in Daegu and Kyungbuk. The measurements are LMT and Adolescent Mental Health and
Problem Behavior-II(AMPQ-II). This study established 12 interpretation criteria, which consisted of 8
composition indices and 4 color indices. Data analysis was performed using cross tabulation. The results are
as follows. First, the indices for integration, cubic expression, perspective, bridge, reality of figures,
connection to items, deviating the fence, color fit, number of colors, and mixed colors show a significant
difference by emotional levels. It is shown that low-risk group's LMT paintings have more integration,
perspective, reality of figures, color fit, number of colors, mixed colors, and less deviating the fence, than
high-risk group's LMT paintings. Second, the indices for integration, cubic expression, perspective, deviating
the fence, color fit, number of colors, and mixed colors show a significant difference by suicidal ideation. It
is shown that LMT paintings of group devoid of suicidal ideation have more integration, cubic expression,
perspective, color fit, number of colors, and mixed colors, and less deviating the fence, than LMT paintings
in the suicidal ideation group. In conclusion, this study found that LMT can be a useful tool to assess
adolescents' emotion.
