Abstract The present study identified relationships between the CATI personality disorder scales and judgmental attitudes and behavior as measured by the First Impression Interaction Procedure [FIIP; Personality and Individual Differences, 33(1) (2002) 131]. A total of 134 women and 42 men completed two separate 25-min uncontrolled interaction sessions as specified by the FIIP. Scores on the 14-item FIIP rating form were then combined to quantify first impression central tendency (Judgment Index), variability (Judgment Variability Index), and the degree to which participants judged others more harshly than self (Judgment Ratio). Eight of the CATI personality disorder scales were able to predict FIIP forms of judgmental behavior and attitude. CATI personality disorder predictors of the FIIP indices were generally weaker than those found in a prior analysis of the MCMI-II. The present CATI analysis was unsuccessful in replicating the specific gender by personality trait interactions on JR scores found previously. Significant interactions were found between gender and JR scores on the avoidant and dependent scales, and seven of the JR and personality scale correlations differed in strength on the basis of gender. These collective findings provided further support for the hypothesis of King and Pate [MCMI-II personality disorder scale predictors of judgmental tendencies as measured by the First Impression Interaction Procedure. Personality and Individual Difference (in press)] that judgmental attitude and behavior may be mediated by different personality factors among men and women.
