DSM-5

In this study, we developed the Japanese version of the Personality Inventory for DSM-5Brief Form (PID-5-BF-J), and examined its reliability and validity. PID-5-BF-J is a measure of maladaptive personality traits, which is a dimensional view of personality disorders in DSM-5 Part III. A total of 254 university students participated in the study, and 52 students cooperated in the retesting conducted at 2-week intervals. In addition to PID-5-BF-J, NEO-FFI, based on the five-factor model of personality, and SCID-5-PD, based on the diagnostic criteria for personality disorders, were used to examine criterion-related validity. The results of confirmatory factor analysis showed inadequate goodness of fit, leaving issues of factor validity. The correlations between PID-5-BF-J, NEO-FFI and SCID-5-PD were generally consistent with previous studies, suggesting a certain criteri-on-related validity. The results suggest that PID-5-BF-J have a certain criterion-relevant validity. Although further investigation of the factor validity, which is a particular issue, is desirable, by considering maladaptive personality traits as pre-morbid personality, it is expected to consider preventive interventions for clinical problems and to lead to self-understanding and acceptance of the respondent’s own personality.
