Supporting adolescents who engage in high-risk behaviors requires a therapeutic approach that is structured, compassionate, and clinically rigorous. Teen DBT in Practice provides therapists with a clear, step-by-step framework for delivering Dialectical Behavior Therapy (DBT) to young people with consistency and confidence. Emphasising structure, flexibility, and fidelity, the book offers practical guidance for addressing self-harm and suicidal behaviors in young people. Written by a Linehan board-certified DBT clinician, this guide integrates individual therapy, skills training, caregiver involvement, and phone coaching into a unified, adolescent-specific model. It includes ready-to-use tools such as guidance on diary cards, session outlines, treatment hierarchies, commitment strategies, and creative, teen-friendly interventions designed for real-world clinical settings. Grounded in extensive clinical practice, Teen DBT in Practice supports immediate implementation while prioritising progress tracking, family collaboration, and therapist sustainability, making it an essential resource for clinicians delivering ethical, effective DBT with high-risk teens.
