This webinar provides a brief introduction to the DSM5 Section III Alternative Model of Personality Disorder. After a brief introduction of the model and the instruments we follow up with two case examples that illustrate how the AMPD has clinical- and client utility. We will show how TA helped us to improve the utility of the model in clinical practice. More specifically, we will present case material related to the standard intake procedure in the context of adult patients with severe personality pathology. Aspects of case-formulation and particularly client feedback are discussed. Next, we present the case of an adolescent client with pervasive interpersonal problems for whom the AMPD assessment included her parents. Collectively, their AMPD assessment served a critical role in acceptance of the feedback as well as subsequent compliance with recommendations.
