The Personality Inventory for the DSM-5 (PID-5) was developed as a measure of the traits included in the Alternative Model of Personality Disorders (AMPD) in Section III of the DSM. The PID-5 is composed of 25 scales measuring each trait in the AMPD across five domains: Negative Affectivity, Detachment, Disinhibition, Antagonism, and Psychoticism. Previous research suggests that there may be important differences in the expression of personality pathology across race and culture, particularly between people with Eastern and Western cultural heritages. The goal of the current research was to examine the measurement invariance of the PID-5 across these groups. In the current study, 865 young men and women who identified as White, East Asian, or Southeast Asian completed the PID-5 and International Personality Item Pool (IPIP). On the domain level, a multigroup exploratory structural equation model found that the PID-5 had configural and metric invariance, but lacked complete scalar invariance. On an item level, all scales had configural invariance, one lacked metric invariance, and 11 of the 25 scales lacked scalar invariance across race. For the invariant scales, East and Southeast Asians tended to have higher mean scores than White participants. The PID-5 scales had similar relations with IPIP scales across groups. These results suggest that the PID-5 scales are measuring similar constructs across groups on global, structural level, but that mean scores may represent different levels of latent personality pathology across groups. The PID-5 may be confidently used in these groups, but mean comparisons should be interpreted with caution.

Two of the most commonly used psychosis screening measures are the Prodromal Questionnaire-Brief (PQ-B) and the Youth Psychosis at Risk Questionnaire-Brief (YPARQ-B). Both scales have considerable support for the reliability and validity of their scores for use with English- and Spanish-speaking participants, with measurement equivalence established across a subset of demographic characteristics. However, measurement invariance has not been examined across several important demographic variables, including: native language, language of the scales used with Hispanic participants, education, occupation, income, birth country, and generation status. In the current study (N = 1,202) measurement invariance was examined for each of these variables across three samples (ns = 505, 713, and 126). The PQ-B total scores and YPARQ-B were found to demonstrate configural and scalar invariance, while PQ-B Distress scores displayed configural, metric, and scalar invariance across most tested demographic variables. Psychosis scores were associated with social determinants of health including major and everyday experiences of discrimination, food insecurity, financial insecurity, acculturation, and ethnic identity. The associations between psychosis and social determinants of health were mostly consistent across groups. Compared to White-non-Hispanic participants, Hispanic participants had higher scores on all psychosis measures and tended to have higher scores on discrimination, food and housing insecurity, affirmation aspects of ethnic identity, and acculturative stress. Despite differences in psychosis levels, the groups did not differ in history of treatment. Overall, these results provide strong evidence that the PQ-B and YPARQ provide equivalent, non-biased, valid, and reliable scores in Hispanic and Non-Hispanic participants in both English and Spanish.
