The Sibling Therapy Starter Kit includes five documents:

• Clinical Orientation Guide — An orientation to adult sibling therapy as a subset of family systems work. Covers the dynamics worth paying close attention to in sibling cases: why unchosen peer relationships carry their own clinical texture, how shared adversity produces divergent responses, how older siblings become attachment figures, the role of parental favoritism and role rigidity, and when sibling work is and isn't indicated. Grounded in the frameworks of Karen Gail Lewis and EFT/EFFT.

• Pre-Intake Assessment Questions — A two-part questionnaire sent to each sibling separately before the first appointment. Covers sibling relationship history, family of origin, favoritism, roles, presenting concern, goals, hesitations, and safety. Formatted as clean question lists with framing language for each section, not fill-in forms. Designed to give you a clinical picture of each sibling's account before they're in the room together.

• Intake Assessment and Ongoing Session Structure Guide — Covers how to use the pre-intake responses in the intake appointment, how to open and close the intake, how to map the relational dynamic live in the room, and a general treatment arc across four phases of sibling therapy. Also covers the core ongoing session work, tricky clinical moments, when the work stalls, the closing phase and termination, and a composite sample session exchange with clinical annotation.

• Client Psychoeducation Handouts — Three ready-to-use handouts for clients: why sibling relationships get stuck and stay stuck, sibling roles and frozen images, and how shared adversity produces divergent adaptations. Each includes reflection questions for between-session work.

• Resource & Further Training Guide — An annotated list of sibling-specific reading and training resources, including Karen Gail Lewis's foundational and most recent work, the EFFT training pathway through ICEEFT, equity-informed resources, and consultation options.

→ A sibling case has landed on your caseload and you don't have a sibling-specific framework for it

→ You're building a niche or specialty practice and sibling therapy is underserved in your market

→ You know family systems well but want deeper clinical grounding in the specific dynamics siblings carry

→ You want to offer a service almost no one else is doing

This kit is written for LMFTs and relational therapists with graduate-level training. It assumes familiarity with family systems and attachment — it doesn't re-teach what you already know.
