 In this study, we have studied the correlations between the level of implicit self-esteem and depression.An experimental survey using a paper and pencil version of the Implicit Association Test( IAT)and a questionnaire were conducted against college students. The questionnaire included the ExplicitSelf-Esteem Scale, Self-Rating Depression Scale (SDS), and depression scales such as SubjectiveAdjustment Scale for Adolescents, Self-Oriented Perfectionism Scale, and Subjective Well-Being Scale.The results of the surveys were analyzed from the perspectives of gender and grade differences aswell as the level of implicit and explicit self-esteem. From the assessment of the survey results, wehave evolved the following hypothesis:( 1) Implicit and explicit self-esteem are independent and notcorrelated. (2) When the levels of implicit and explicit self-esteem are inconsistent, the depressionlevel would be higher than when they are consistent. Previous studies have reported that when thelevels of implicit and explicit self-esteem are inconsistent, people are motivated to solve the inconsistency.The development of social maladjustment was expected as a consequence. The results supportedHypothesis (1) whereas Hypothesis (2) was not proven to be true. This result might havebeen caused by the issue in the survey control (experimental survey method, participants, andresearch designs). People with high self-esteem had lower depression, were more adaptive, and hadhigher well-being compared to those with low self-esteem. These results supported the previous studiesrelated to explicit self-esteem. The reason why Hypothesis( 2) was not supported may be becauseof the difficulty of precise measurement and detailed observation of the psychological adjustment inthe case of depression with the researches focused only on explicit self-esteem using self-administeredquestionnaires.
