Abstract

In this study, latent profile analysis of Bright and Dark Personality Inventory-Short Form was conducted and verified whether it was equivalent to the latent profile analysis result of the original form. Collected 1,059 people data for BDPI validation study was used, and latent profile analysis was conducted on the 10 high-order factor score of General personality 5 and Maladaptive personality 5 factor. In BDPI original form, latent group was determined as three groups. and BDPI short form’s latent group was determined as three groups like the orignal form. These three groups were named as “well-adjusted personality group”, “ordinary personality group”, “maladaptive personality group”. As a result, the score distribution of each group of the two forms were similar each other like that score distribution was found before, the percentage agreement between the original form and the short form was 86.89%, and the Cohen’s kappa coefficient between the original form and the short form was .778, showing a significant level of agreement. The difference in personality scores according to three latent groups of the short form was statistically significant. When the difference in personality scores of the high-order 10 factors according to the latent group was confirmed, the two groups with no score difference in general personality trait showed a significant difference in maladaptive personality trait. The latent groups predict differently Self-Report Standardized Assessment of Personality- Abbreviated Scale(SAPAS-SR) score, which proved prediction validity of BDPI-SF. The score differences according to each group were statistically significant, and the maladaptive personality group predicted the high SAPAS-SR average score. Finally, contributions and limitations of this study were presented in the discussion section.
