MMPI 단축형 우울척도 개발: 문항기반 요인분석의 사용

Abstract

The Minnesota Multiphasic Personality Inventory(MMPI) is one of the most popular and widely used personality assessment instruments in various settings. The primary advantage of the MMPI-2 is to provide an accurate and comprehensive personality profile based on affluent data. On the other hand, a shortcoming of the MMPI is that length of the test instrument and amount of time required for test administration are too long. Therefore, many researchers have developed short forms of the MMPI, which were of less items and less time consuming than the full MMPI, while retaining its validity and clinical utility. The purpose of this study was to develop a short form of the MMPI-2 (Depression scale) using full-information item factor analysis method. The reliability and validity of our short form were reasonably good. Three factors were extracted and labelled as subjective depression, difficulty in interpersonal relations, and decrease of physical activities respectively. The items of our short form showed a very high utility(R2=.948) of predicting scores of the full version and high correlations(.449∼.898) with Harris-Lingoes subscales and depression subscales. These results indicate that the short form has adequate reliability and validity, and explains the variability of the full version scores sufficiently. Thus it can be used as a substitute when it is not feasible to use the full version. Finally, the implications and limitations of the study along with suggestions for future research are discussed.
