The Personality Inventory for DSM-5 (PID-5) evaluates 25 maladaptive personality traits proposed in the Alternative Model of Personality Disorders. The questionnaire has been extensively investigated and validated in several languages. The current research sought to examine the psychometric properties of the instrument in a sample of nonclinical Romanian participants (N = 1276). Results indicated excellent internal consistency for the domain level, and very good reliability for the facet level. The assumption of unidimensionality was supported at both the domain and facet levels, apart from Risk Taking. Two domain scoring methods were also compared. One of them takes into consideration all the 25 lower order facets, whereas the other uses only 15 facets. Results show that mean differences across the two scoring methods were small, except for Disinhibition. Moreover, confirmatory factor analyses revealed slightly better fit indices for the model which uses 15 facets only. Lastly, the hierarchical structure of maladaptive personality traits was explored. Results are discussed in the light of previous literature.

People with borderline personality disorder (BPD) feel instability in self-image, affects and relationships. The current study aimed to examine the psychometric properties of the Borderline Personality Questionnaire (BPQ) in a sample of 737 nonclinical Romanian adults. Results indicated mostly satisfactory internal consistency for the subscales and high internal consistency for the total score of the scale. A factor analysis showed a one-factor solution that accounted for 50.21 % of the observed variance. Evidence for convergent validity, tested by evaluating the associations between borderline traits, anxiety, depression, stress, life satisfaction and impulsivity traits, was confirmed, but the assumptions for divergent validity were not met. Results are discussed considering previous studies. Future research is needed to fully evaluate its psychometric properties.
