Abstract
The Alternative DSM-5 Model for Personality Disorders (AMPD) consists of level of personality functioning (Criterion A) and maladaptive personality traits (Criterion B). The brief scale versions of these are understudied, while often being used by clinicians and researchers. In this study, we wanted to investigate the overlap and predictive validity of Criterion A and B. Participants (N = 253) were measured on level of personality functioning (LPFS-BF) and maladaptive personality traits (PID-5-BF), as well as internalizing outcomes such existential meaninglessness (EMS) and externalizing outcomes such as substance and behavioral addictions (SSAB). Data analysis was conducted with principal component analysis (PCA) and regression analyses.... (More)

Data analysis was conducted with principal component analysis (PCA) and regression analyses. The results showed over 50% overlap between the brief versions of Criterion A and B, while Criterion B slightly outperformed Criterion A in outcomes of EMS and SSAB. We discuss the potential redundancy and usefulness of personality functioning and maladaptive personality traits. (Less)
