The present study was a psychometric evaluation of two recently revised Jungian personality instruments, the Singer-Loomis Type Deployment Inventory (SL-TDI) and the Personal Preferences Self-Description Questionnaire (PPSDQ). The study also examined the relationship between Jungian personality dimensions and the Five-Factor Model of personality (neuroticism, extraversion, agreeableness, openness to experience, and conscientiousness), using the NEO Five-Factor Inventory (NEO-FFI). These three instruments and a demographic questionnaire were administered to 305 college undergraduates. Alpha coefficients indicated very good reliability of scores from the SL-TDI and the PPSDQ. Bivariate and canonical correlations between the two Jungian personality instruments and predicted scales on the NEO-FFI provided support for the construct validity of scores from both Jungian personality instruments.
