This training is designed to equip trauma therapists with new techniques to maintain equanimity and promote synchronicity during relationship-focused treatment of complex trauma treatment. Therapists will learn how to integrate attachment and trauma theories into their clinical work with clients; they will learn interpersonal neurobiology-based micro-skills to develop attunement with clients; skills to effectively manage ego defenses that are activated during trauma reprocessing; skills to contain emotional abreactions; tools to promote the reintegration of clients’ projections onto the therapist; how to develop a two-person relational approach to managing countertransference, and skills to cultivate compassion for clients with challenging CPTSD symptoms.
