Expertly designed, the Structured Clinical Interview for the DSM-5 Alternative Model for Personality Disorders (SCID-5-AMPD) is a semistructured diagnostic interview that guides clear assessment of the defining components of personality pathology as presented in the DSM-5 Alternative Model. The modular format of the SCID-5-AMPD allows the researcher or clinician to focus on those aspects of the Alternative Model of most interest. Module II: Structured Clinical Interview for Personality Traits focuses on the dimensional assessment of the five pathological personality trait domains in the Alternative Model and their corresponding 25 trait facets. This comprehensive review of the trait domains (Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism) identifies multiple areas of personality variation and provides a visual profile of trait facets across the trait domains. Module II can be used independently or in combination with any of the following SCID-5-AMPD modules: • Module I dimensionally assesses self and interpersonal functioning using the Level of Personality Functioning Scale.• Module III comprehensively assesses each of the six specific personality disorders of the Alternative Model, as well as Personality Disorder–Trait-Specified. Also available is the User's Guide for the SCID-5-AMPD: the essential tool for the effective use of any SCID-5-AMPD module. This companion guide provides instructions for each SCID-5-AMPD module and features completed samples of all modules in full, with corresponding sample patient cases and commentary. Trained clinicians with a basic knowledge of the concepts of personality and personality psychopathology will benefit from the myriad applications and insights offered by the SCID-5-AMPD.
