Are personality disorder criteria ethnically biased? A card-sort analysis

On the basis of methodology used in previous research on sex criterion bias, this study examined ethnicity criterion bias of personality disorders (PDs) defined in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., Rev.) and included examination of sex as well as ethnicity. A card-sort analysis using undergraduate college students as sorters indicated that criteria for all of the PDs were applied disproportionately by ethnicity, resulting in particular ethnic groups receiving diagnoses for specific PDs. Criteria were sorted systematically such that diagnoses of antisocial and paranoid PDs were assigned to African Americans, schizoid PD was assigned to Asian Americans, and schizotypal PD was assigned to Native Americans. All other PDs were assigned to European Americans, whereas none of the criteria were sorted resulting in any PD diagnosis being applied to Latinos. Implications for clinicians, methodological considerations, and recommendations for future research are discussed.
