The DSM-5 Section III alternative model of personality disorder (AMPD) and the International Classification of Diseases – 11th Edition's (ICD-11) personality disorder classification allow clinicians to identify individual trait domains in which people score highly. However, how these domains relate to constructs associated with efficacious treatment approaches is unclear. The current study aimed to determine whether constructs from two evidence-based treatments (schema therapy [ST] and dialectical behavior therapy [DBT]) were associated with maladaptive personality traits in a way consistent with underlying theories. We examined associations between ST constructs, DBT skill use and maladaptive coping styles, and personality traits in a sample of 525 adults. Bivariate intercorrelations and a series of multiple regression analyses were conducted to investigate the associations. As hypothesized, maladaptive coping was strongly associated with all trait domains. Surprisingly, poor DBT-skill use was only associated with negative affectivity, detachment, and disinhibition trait domains. Specific schema domains were associated with each personality trait domain, supporting trait domain-schema domain specificity. The current study highlights the potential clinical utility of the AMPD and ICD-11 trait models and ultimately contributes to the dearth of evidence on their likely usefulness for treatment selection, planning, and applications.
