The purpose of this study is to explore responsive characteristics which university students’ show in the drawings of the ‘PPAT’ (person picking an apple from a tree) according to their level of ‘employment stress’ and ‘self-esteem.’ This study would be helpful to find the possibility of using ‘PPAT’ as a supplemental tool to enhance an objective psychological assessment in clinical field. Two hundred twenty-two university students without emotional and behavioral disorders were voluntarily participated in this study. They responded the ‘Scale of Employment Stress (SES),’ ‘Rosenberg Self-Esteem Scale (RSES),’ and drew a picture of ‘PPAT.’ The upper 30% respondents (N=68) of scale of employment stress were selected among the 222 respondents, 11 false respondent excluded. The selected respondents were divided into upper and lower groups based on the mean value of ‘RSES.’ FEATS (Formal Elements Art Therapy Scale) was used as a scoring system to analyze formal factors of the picture, and contents of the picture were treated through Contents Scale. The results of this study are as follows. The high employment stress subjects did not presented the differences on the FEATS Scales according to their self-esteem levels. However, some items of Contents Scale, such as ‘Approximate Age of Person,’ ‘Color of Apple Tree,’ and ‘Environmental Details' were significantly different according to the subjects’ self-esteem levels. In conclusion, the results suggest that ‘PPAT,’ a simple and low cost assessment tool for university students who are busy to prepare their future employment, may be of utility as a drawing test to understand, inspect, explore and express university students’ mental state.
