As the empirical literature on the clinical utility of the AMPD grows, there is a need to examine changes in diagnostic profiles and personality expression in treatment over time. Assessing these changes in individuals diagnosed with borderline personality disorder (BPD) is complicated by the tendency for patients to cycle through multiple therapists over the course of treatment leaving the potential for muddled diagnostic clarity and disjointed case conceptualizations. Following patient trajectories across therapists offers a unique opportunity to examine the AMPD\u2019s sensitivity to and utility for capturing personality stability and change over time for patients with BPD. This article demonstrates the utility of the AMPD for two clinical cases in three distinct ways: (i) highlighting heterogeneity in BPD between patients, (ii) comparing improvements in personality severity and style over time, and (iii) elucidating profile change across therapist ratings. We present two patients diagnosed with<jats:italic>DSM<\/jats:italic>-5 Section II BPD, crossing between two therapists over the course of 3 years of psychodynamic psychotherapy. Treating clinicians rated patients for their respective treatment phases using the Level of Personality Functioning Scale (LPFS), capturing severity, and the Personality Inventory for the<jats:italic>DSM<\/jats:italic>-<jats:italic>5<\/jats:italic>(PID-5), capturing style. AMPD diagnostic profiles differentiated patients with BPD in both severity and style, and captured within-patient change beyond within-therapist response bias. Results indicated greater improvements in personality severity while personality style remained more stable. Implications for the patients\u2019 treatment progress and associated challenges are discussed, as are considerations for the utility of the AMPD in therapy.<\/jats:p>","DOI":"10.3389\/fpsyg.2022.794624","type":"journal-article","created":{"date-parts":[[2022,2,14]],"date-time":"2022-02-14T17:52:17Z","timestamp":1644861137000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Trading Patients: Applying the Alternative Model for Personality Disorders to Two Cases of DSM-5 Borderline Personality Disorder Over Time and Across Therapists"],"prefix":"10.3389","volume":"13","author":[{"given":"Chloe F.","family":"Bliton","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lia K.","family":"Rosenstein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron L.","family":"Pincus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,2,14]]},"reference":[{"key":"B1","year":"2013","journal-title":"Diagnostic and statistical manual of mental disorders: DSM-5"},{"key":"B2","doi-asserted-by":"publisher","first-page":"329","DOI":"10.1016\/j.comppsych.2007.02.001","article-title":"Psychosocial impairment and treatment utilization by patients with borderline personality disorder, other personality disorders, mood and anxiety disorders, and a healthy comparison group.","volume":"48","author":"Ansell","year":"2007","journal-title":"Comprehen.
