Assessing Criterion A of the Alternative Model for Personality Disorders: The Potential of Performance-Based Personality Measures.

The conceptualization of personality disorder has been refined through recent nosological advances introduced in the Alternative Model for Personality Disorders (AMPD). These advances locate self and interpersonal (dys)function at the core of personality pathology. Self-report personality assessment instruments have demonstrated promise in the assessment of Criterion A domains. However, research highlighting the utility of performance-based personality assessment instruments has been largely absent in these advances, despite acknowledgment of their potential. We adhered to PRISMA review guidelines to survey and assess the potential relevance and utility of select performance-based personality instruments in assessing Criterion A domains of the AMPD. We conclude that performance-based personality measures are uniquely positioned to assess maladaptive self- and interpersonal functioning and may address some limitations of self-report measures. Toward this end, we propose a working model that provides ranges of test scores that correspond to the 5-point scale of the Criterion A domains of the AMPD.
