This study analyzed responses to the House-Tree-Person (HTP) test based on the Big Five personality
traits. To identify the relevant response indicators for the HTP test, a temporary website was created to
collect 363 HTP sample pictures from subjects over the age of 20 and without any relevant experience.
Three experts with master’s degrees in art therapy devised the HTP test analysis table by compiling the
indicators that appeared in more than 15% of the collected samples and by referring to existing works on
HTP analysis. Using convenience sampling methods, the researchers conducted the HTP test and NEO-
Ⅱ Personality Inventory on students of 11 universities from Seoul/Gyeonggi, Youngnam, Honam,
Choongchung, and Gangwon provinces during March 2015. Of the collected data, 783 pictures were used as
valid data samples for analysis. The degree of consistency among the raters was found to be r=0.97.
Through dichotomous logistic regression analysis and multiple logistic regression analysis, it was found that
20 indicators were statistically significant. When the Big Five personality traits and their subordinate traits
were used as the basis for interpreting the Person pictures, the results were largely in line with those from
the preceding studies and the existing clinical results.
