In this study modified forms of MBT and UP \u2013 MBT\u2010A and UP\u2010A respectively\u2014were compared in their ability to reduce borderline symptoms in a sample of 91 Iranian adolescents (two\u2010thirds female) with a BPD diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Individuals randomly allocated to one of two treatment groups, MBT\u2010A (<jats:italic>N<\/jats:italic>\u2009=\u200945) or UP\u2010A (<jats:italic>N<\/jats:italic>\u2009=\u200946) were followed up across 36\u2009months following treatment. A MIXED ANCOVA was applied to compare the effectiveness of these interventions in reducing severity of borderline symptoms (the primary outcome), impulsivity, self\u2010harm, emotion dysregulation and anger (secondary outcomes). The trial was retrospectively registered at IRCT20231106059970N1.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both primary outcomes and secondary outcomes decreased significantly following both MBT\u2010A and UP\u2010A. In comparison with MBT\u2010A, UP\u2010A was more effective in reducing emotional dysregulation, but levels of remission declined progressively up to 36\u2009months of follow\u2010up following both treatments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>UP\u2010A appears to be more effective than MBT\u2010A in reducing emotional dysregulation in adolescents with BPD, despite being a shorter and less intensive treatment. An important <jats:italic>caveat<\/jats:italic> is that the treatment induced changes were largely limited to the emotion dysregulation aspect of BPD; other aspects (interpersonal and identity disturbances) were largely unchanged by either treatment.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cpp.70033","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T15:20:16Z","timestamp":1738596016000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Unified Protocol vs Mentalization\u2010Based Therapy for Adolescents With Borderline Personality Disorder: A Randomized Controlled Trial"],"prefix":"10.1002","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1765-2884","authenticated-orcid":false,"given":"Banafsheh","family":"Mohajerin","sequence":"first","affiliation":[{"name":"Taleghani Hospital Research Development Committee, School of Medicine Shahid Beheshti University of Medical Science  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew\u00a0W.","family":"Gallagher","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Houston  USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5397-7198","authenticated-orcid":false,"given":"Richard","family":"Howard","sequence":"additional","affiliation":[{"name":"Institute of Mental Health  Nottingham UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,2,3]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"1667","volume-title":"Assessing Alcohol Problems: A Guide for Clinicians and Researchers (No. 3)","author":"Allen J.
