Abstract
Public Significance Statement In this study, the authors report that a commonly used instrument to assess personality pathology (the Personality Inventory for DSM-5 [PID-5]) is not an equivalent measure across Black Americans and White Americans. Until other evidence emerges to suggest otherwise, we advise against its use in Black American samples.
The Personality Inventory for the DSM-5 (PID-5) assesses the five pathological personality trait domains that comprise the descriptive core of the DSM-5 Alternative Model of Personality Disorders (AMPD). The PID-5 five-domain factor structure is aligned with the AMPD and is reported as replicable across samples in the U.S., in other countries, and in different languages. In this study, the PID-5 factor structure is examined in two distinct racial groups within the U.S.-White Americans (WA) and Black Americans (BA). Student participants from four universities in the U.S. (N = 1,834)-composed of groups of WA (n = 1,274) and BA (n = 560)-were proportionally parsed into derivation and replication subsamples. The "traditional" PID-5 five-factor structure emerged for the WA group in the derivation subsample and was subsequently confirmed in the WA replication subsample. In the BA group derivation subsample, a single-factor solution emerged, which was also confirmed in the BA replication sample. This single-factor solution in the BA group reflects large shared covariation across all pathological personality domains, suggesting an undifferentiated, broadly based level of demoralization represented by the item pool of the PID-5. We argue that this structure can be construed as mirroring a racialized and prejudice-based living experience for many BAs in a predominantly non-Black society. Based on the results with the samples employed in the present study, we conclude that the PID-5 is not an equivalent measure of pathological personality traits across Black Americans and White Americans.
