Eye Movement Desensitization & Reprocessing (EMDR) is a powerful and well-established methodology for treating PTSD, but numerous concerns have been raised about its safety and efficacy when used in a context of complexity, such as significant attachment wounds, and multiple or complex trauma. Interweaving various formulations of ego state therapies (EST) has been described and utilized to support and enhance safe utilization of EMDR procedures (Paulsen, 2018; Shapiro, 2018; van der Hart et al.,2014; Forgash & Copeley, 2008). Internal Family Systems therapy (IFS) is an evidence based (Hodgdon et al., 2022) ego state therapy which offers unique qualities that match key components of the EMDR’s foundational Adaptive Information Processing (AIP) model. IFS methods have been utilized in the context of EMDR therapy to enhance therapist-client communication about their internal experience and trouble-shoot processing difficulties (O’Shea Brown, 2020; Gomez & Krause, 2013; Twombly & Schwartz, 2008). Both IFS and EMDR have been described as experiential psychotherapies which can facilitate a form of neuroplasticity called memory reconsolidation, which uniquely unlocks and rewrites implicit memories that underlie many of the symptoms treated with these methodologies (Ecker et al, 2012). Some concepts and language from Coherence Therapy supports and clarifies key IFS concepts around exploring positive (adaptive) intentions behind symptoms with curiosity, compassion & persistence (i.e., Self-presence), while also mirroring the requisite dual attention condition for EMDR processing. These additional conceptual tools enable the IFS-informed EMDR therapist to more consistently generate juxtapositions (a critical condition required for memory reconsolidation), beginning in the Assessment Phase of EMDR and continuing through the subsequent phases of the EMDR Standard Protocol (Ecker & Bridges, 2020; Ecker et al, 2012).In Syzygy Institute’s Step One: Intro to IFS for EMDR Therapists 2-day Experiential workshop, psychologists, social workers, mental health counselors, and marriage & family therapists are taught the basic outline and key concepts of the model with an opportunity to experience guided practice sessions in therapist and client roles, after seeing these exercises demonstrated live by workshop instructors, thus observing numerous examples of the process throughout the workshop. Course material is developed from standard IFS background texts & training manual (Schwartz & Sweezy, 2020; Anderson, 2021; Anderson et al., 2017) and each workshop is led by an instructor who has completed IFS training and certification by the IFS Institute.Intro to IFS for EMDR Therapists 2-day Experiential does not teach the integration of IFS and EMDR, although it describes the rationale for supplementing EMDR with an ego state model, and for choosing IFS as that model. For EMDR therapists without IFS training, this is an experiential IFS primer, providing the bare essentials necessary for adequate integration of the models in subsequent Syzygy Institute’s Step Two IFS-EMDR integration course: IFS-Informed EMDR 2-day.Hosted by Syzygy Institute, LLC online for 13 CEs. For more info, visit the event webpage.
