We present the case of a 14-year-old boy who experienced vicarious gender-based violence, child abuse, early maternal separation without alternative secure attachment figures, and forced sudden migration. The patient exhibited symptoms consistent with post-traumatic stress disorder (PTSD) and complex trauma. The culturally sensitive intervention, delivered at a public child and adolescent mental health center, consisted of twenty weekly individual sessions of 45 min each, complemented by three 45 min psychoeducation sessions with the caregiver. The assessment was conducted using a multitrait and multi-informant approach, systematically gathering information across multiple domains of functioning (emotional\u2013behavioral, physical, cognitive, self-perception, and relational) and from different sources (the adolescent, his mother, and the clinician) through clinical interviews, projective techniques, and parental feedback. The primary therapeutic focus was the establishment of a secure therapeutic alliance to facilitate emotional exploration and trauma processing. Following treatment, the patient demonstrated significant improvements in emotional regulation, family relationships, and school performance, as measured by both self-report and parental observations. This case highlights the potential of BFP in addressing complex trauma in adolescents, particularly during a developmental stage marked by increased vulnerability to the effects of chronic trauma exposure. The findings suggest that BFP can effectively reduce both acute symptomatology and broader psychosocial consequences associated with prolonged and cumulative trauma. Further research, particularly controlled studies and longitudinal follow-ups, is needed to refine and optimize the use of BFP by mental health professionals working with adolescents affected by complex trauma.<\/jats:p>","DOI":"10.3390\/bs15060784","type":"journal-article","created":{"date-parts":[[2025,6,6]],"date-time":"2025-06-06T03:52:28Z","timestamp":1749181948000},"page":"784","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Treating Complex Trauma in Adolescence: A Case Study of Brief Focal Psychotherapy After Vicarious Gender Violence and Child Abuse"],"prefix":"10.3390","volume":"15","author":[{"given":"Georgina","family":"Rosell-Bellot","sequence":"first","affiliation":[{"name":"Facultad de Ciencias de la Salud y la Educaci\u00f3n, Universidad a Distancia de Madrid, 28010 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4230-7268","authenticated-orcid":false,"given":"Eva","family":"Izquierdo-Sotorr\u00edo","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud y la Educaci\u00f3n, Universidad a Distancia de Madrid, 28010 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4461-7865","authenticated-orcid":false,"given":"Ana","family":"Huertes-del Arco","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud y la Educaci\u00f3n, Universidad a Distancia de Madrid, 28010 Madrid, Spain"},{"name":"Facultad de Psicolog\u00eda, Universidad Nacional de Educaci\u00f3n a Distancia, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4682-6695","authenticated-orcid":false,"given":"Mar\u00eda","family":"Rueda-Extremera","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud y la Educaci\u00f3n, Universidad a Distancia de Madrid, 28010 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2536-9499","authenticated-orcid":false,"given":"Mar\u00eda Elena","family":"Brenlla","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud y la Educaci\u00f3n, Universidad a Distancia de Madrid, 28010 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,6]]},"reference":[{"key":"ref_1","first-page":"15","article-title":"Extreme migrant bereavement: The chronic multiple stress immigrant syndrome (Ulysses syndrome)","volume":"11","author":"Achotegui","year":"2008","journal-title":"Journal of Psychopathology and Mental Health of the Child and Adolescent"},{"key":"ref_2","first-page":"33","article-title":"Psychotherapeutic interventions based on attachment theory","volume":"33","author":"Aguilar","year":"2019","journal-title":"Revista C\u00fapula"},{"key":"ref_3","first-page":"741","article-title":"Psychological alterations in minors exposed to gender violence: Prevalence and gender and age differences","volume":"29","author":"Castro","year":"2013","journal-title":"Revista Anales de Psicolog\u00eda"},{"key":"ref_4","unstructured":"Allen, J.
