This study examined the factor structure of the MMPI-A basic and content scales based on the data of Korean normal and clinical adolescent samples. Principal factor analyses were conducted on the raw score data for 13 MMPI-A basic scales and 15 content scales, respectively. Analyses of the 13 basic scales yielded a three-factor solution for boys and girls in the normal sample and for the combined normal group. The three factors were labeled general maladjustment, repression/overcontrol, and social introversion. The fourth factor, masculinity-femininity, was obtained for the combined clinical group. Analyses of the 15 content scales produced a two-factor solution for all samples. The two factors were considered as externalizing tendencies and social discomfort. These results indicate that the factor structure of the Korean MMPI-A may be seen as relatively robust and stable within and across gender and settings. Given the limitations of this investigation, the results of this study would be an important step toward establishing the factor structure of this new instrument.
