This study endeavors to explore the application and effectiveness of Structural Family Therapy (SFT) in addressing adolescent behavioral issues, utilizing a case study methodology. SFT, a therapeutic method that intervenes at the level of the family system, emphasizes restructuring the family and clarifying boundaries among its members. By selecting emblematic cases, this study meticulously analyzes the foundational principles employed in therapy alongside specific techniques, including enhancement of family functionality, adjustment of family structure, and resource-oriented strategies. This research probes into the effectiveness and theoretical foundations of Structural Family Therapy (SFT) in tackling adolescent behavioral challenges, highlighting its unique contributions to family therapy. Through an exhaustive examination of seminal cases from distinguished practitioners such as Minuchin, Fishman, and Lee, Wai–Yung, the paper elucidates SFT's proficiency in navigating the dynamics of family systems. It reveals how the therapy's strategic modifications in interaction patterns and boundary configurations among family members catalyze notable improvements in adolescent behaviors. These transformations transcend mere direct interventions; they epitomize a deeper, collaborative process engaging both therapists and family units. The findings further illuminate SFT's prowess in enhancing family functionality, thereby fostering an environment conducive to nurturing adolescent independence. This exploration affirms SFT's pivotal role in reshaping familial interactions, thereby mitigating adolescent behavioral issues through a holistic and collaborative approach that benefits the entire family structure. Moreover, this study additionally concentrates on the sustainability of treatment outcomes and their impact on the overall well-being of family members, aiming to provide a comprehensive evaluation of SFT's efficacy in ameliorating adolescent behavioral issues. Through an in-depth analysis of the cases, this research reveals the details of SFT's application in practice and its potential to foster positive changes in adolescent behavior and enhance overall family function. The results aim to provide mental health professionals with effective strategies for treating adolescent behavioral problems and to offer further theoretical and practical guidance in the field of family therapy.
