This study was conducted to measure the level of reliability of the MJPI, and to explore effects of faking test behavior, IQ and at random response on MJPI.
Findings were as follows :
(1) Reliability of MJPI was attested with a good level of internal consistency.
(2) Although it seemed to be easy to operate responses to questionnaire items of the MJPI in terms of social desirability, few delinquents made their responses socially desireble ones.
(3) The test behaviors of juvenile delinquents in the Juvenile Classification Home were not comparatively defensive. Many delinquents frankly showed their shortcomings.
(4) IQ was proved to be a significant factor to vary MJPI scores. The MJPI scores of the Sbs with IQ 69- were quite different from those of the Sbs with IQ 70+.
