Personality inventory for DSM-5-Brief Form (PID-5-BF): Measurement invariance across men and women.

The study examined the measurement invariance (configural, metric, scalar, and residual) of the Personality Inventory for Brief Form (PID-5-BF; Krueger et al., 2013) across gender for the theorized Five-Factor oblique model. A large group of adults ( = 502), with ages ranging from 18 to 67 years, from the Australian general community completed the PID-5-BF. When the Δ² test was applied, multiple-group confirmatory factor analysis supported configural invariance and full metric and residual invariance. For scalar invariance, at least seven items (constituting 13 thresholds) across the different dimensions lacked invariance for one or more of its thresholds. In addition, controlling all these noninvariance thresholds, women had higher latent mean scores for Negative Affect, and men had higher scores for Antagonism and Disinhibition. When the Δcomparative fit index (ΔCFI) test was applied, the findings also supported the configural invariance model and the full metric and residual invariance models. With the exception of one threshold, all the other thresholds were also invariant. The psychometric and practical implications of the findings are discussed.
