본 연구에서는 MBTI의 타당도를 검증하기 위하여 505 명의 피험자를 대상으로 MBTI 실시 결과와 표준화 성격진단검사 결과와의 상관분석 및 일원변량분석을 실시하였다. 그 결과, MBTI 선호지표 중 E는 안정성, 지배성, 사회성, 남향성, 충동성, 우월성과, I는 사려성, 동조성, 임상척도 전부와, S는 책임성, 동조성과, N은 사려성과, T는 안정성, 지배성, 책임성, 사려성, 남향성과, F는 사회성, 동조성, 충동성, 신경질경향과, J는 책임성, 사려성, 동조성과, P는 사회성, 남향성, 충동성과 유의한 정적 상관을 보였다. 그리고 4 기능유형 중 ST는 책임성, 남향성이, SF는 동조성이, NT는 안정성, 지배성, 사려성, 남향성이, NF는 사회성, 충동성이 타유형에 비해 점수가 유의하게 높았다. 또한 4 기질 중 SP는 충동성, 동조성, 불안경향, 신경질경향이, SJ는 책임성, 동조성이 타기질에 비해 점수가 유의하게 높았으며 NT와 NF기질은 기능유형과 동일하게 나타났다.
The purpose of this present study was to test the validity of MBTI (Myers-Briggs Type Indicator) through the relational analysis between MBTI and SPDI(Standardized Personality Diagnosis Inventory). There were 505 people involved in the study. This included 191 high school students, 199 college students and 115 adults. The experiment used on these people was MBTI and SPDI. The data was analyzed to see the relation between the traits of SPDI and four preference indicators of MBTI. The results of the study were as follows ; First, the E indicator of MBTI and SPDI, which include Emotional stability, Dominance, Sociability, Masculinity, Impulsiveness and Superiority, have high positive relations in the context of the relationships between the traits of SPDI and four preference indicators of MBTI. The same is true for the I indicator of MBTI and Reflectiveness, Conformity, Depression, Anxiety, Paranoid tendency, Autism, Nervousness of SPDI. The S indicator of MBTI and Responsibility, Conformity of SPDI have meaningful positive relations and the same is true for the relations between T indicator and Emotional stability, Dominance, Responsibility, Reflectiveness, Masculinity, F indicator and Sociability, Conformity, Impulsiveness, Nervousness, J indicator and Responsibility, Reflectiveness, Conformity, P indicator and Sociability, Masculinity, Impulsiveness. Second, referring to the differences between four function types of MBTI and SPDI, ST type is higher in Responsibility, Masculinity, SF type is higher in Conformity, NT type is higher in Emotional stability, Dominance, Reflectiveness and Masculinity, NF type is higher in Sociability, Impulsiveness more than any other type. Third, regarding the differences between four temperament types of MBTI and SPDI, SP temperament is meaningfully higher in Impulsiveness, Conformity, Anxiety, Nervousness of SPDI than any other temperament type. The same is true for SJ temperament in Responsibility, Conformity, NT temperament in Emotional stability, Responsibility, Reflectiveness, Masculinity, NF temperament in Sociability, Impulsiveness. The results synthesized from this study are as follows ; Four preference indicators of MBTI have very meaningful relations with the traits of SPDI, four function types and four temperament types of MBTI also have meaningful differences compared with the traits of SPDI. Therefore, the result of this study supports that MBTI based on the psychological typology by Carl Jung is a very useful instrument for human understanding.
