PID 5/AMPD Norms
The introduction of the Alternative Model of Personality Disorders (AMPD) in the fifth edition of the Diagnostic and Statistical Model of Mental Disorders (DSM-5, APA, 2013) represented a substantive change in how personality disorders (PDs) are diagnosed. One barrier to its adoption (among several) in clinical practice, however, is a lack of information as to what constitutes an elevated score on the 25 domains and facets that comprise Criterion B. Unique sets of facets can be configured to assess any one of six PDs retained in the AMPD; each of these facets can in turn be added to create a PD sum score.
In a recent study, using the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2012), we reported mean scores, standard deviations, and cut-points that align with 1.0, 1.5, and 2.0 SD elevations for each facet, domain, and PD on the basis of Krueger and colleagues (2012) representative sample. We also compare these to those obtained from a community and a clinical sample. We hope these normative data will be useful to clinicians in determining whether a client has elevated scores on pathological personality domains, facets, or PDs. To further facilitate this, we also provide an excel spreadsheet that will generate z-scores and T-scores on facets, domains, and PDs once an individual's facets scores are entered (with facets computed a average scores). The preprint of the paper and the excel sheet appear below.
