This study assessed the feasibility of the intervention and of a multicentre research design, as a preliminary step towards larger, better\u2010controlled trials. A one\u2010group pretest\u2013posttest design was used across five mental healthcare institutions. Eligible participants were adolescents aged 12\u201318 meeting threshold criteria for a PD under the DSM\u20105 alternative model. Participants (91.9% female; mean age 15.9\u2009years) received GITPD\u2010A for 6\u2009months. Intervention feasibility was evaluated via paired\u2010samples\n                    <jats:italic>t<\/jats:italic>\n                    \u2010tests on pre\u2010 and posttest scores. Feasibility of the multicentre design was assessed by eligibility and enrolment rates, measure completion and study dropout. Significant improvement was found for pathological personality traits (PID\u20105), with a medium effect size (Hedges'\n                    <jats:italic>g<\/jats:italic>\n                    \u2009=\u20090.50). Secondary outcomes showed significant reductions in depression, anxiety, emotion dysregulation and symptoms of borderline PD. Participants reported high satisfaction (\n                    <jats:italic>M<\/jats:italic>\n                    \u2009=\u20098.1). Following a broad screening process involving 245 participants, 65 were found to be eligible. Of these, 47 adolescents took part in the study overall, with 38 completing the intervention. The treatment dropout rate was 19.1% (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20099). Despite the limited sample, preliminary findings support the feasibility of GITPD\u2010A for adolescents with emerging PD, showing high acceptability, satisfaction, retention and acceptance of scientific assessments. Selected measures appear suitable for detecting intervention\u2010related changes. However, a different primary outcome and improved screening strategies may be needed.\n                  <\/jats:p>","DOI":"10.1002\/pmh.70109","type":"journal-article","created":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T01:06:21Z","timestamp":1792631181000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploring the Feasibility of a Generic Early Intervention Programme for Emerging Personality Disorder in Adolescents: Guideline\u2010Informed Treatment for Personality Disorders\u2014Adolescent Version (GITPD\u2010A)"],"prefix":"10.1002","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8245-1824","authenticated-orcid":false,"given":"Paulien","family":"Jansen","sequence":"first","affiliation":[{"name":"NL\u2010PSY  Zwolle the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacquelijne","family":"Schraven","sequence":"additional","affiliation":[{"name":"Altrecht Child and Youth Psychiatry  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Laschen","sequence":"additional","affiliation":[{"name":"iHub  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5641-659X","authenticated-orcid":false,"given":"Stephan","family":"Kraai","sequence":"additional","affiliation":[{"name":"Karakter Child and Youth Psychiatry  Nijmegen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0189-3771","authenticated-orcid":false,"given":"Joost","family":"Hutsebaut","sequence":"additional","affiliation":[{"name":"Viersprong Institute for Studies on Personality Disorders  Halsteren the Netherlands"},{"name":"Department of Medical and Clinical Psychology Tilburg University  Tilburg the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,21]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/10503307.2020.1813914"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/1073191116676889"},{"key":"e_1_2_11_4_1","doi-asserted-by":"crossref","DOI":"10.1093\/med:psych\/9780199644209.001.0001","volume-title":"Borderline Personality Disorder: An Evidence Based Guide for Generalist Mental Health Professionals","author":"Bateman A.
