SMBT is not a variant of EMDR, though it incorporates bilateral stimulation (BLS) as one mechanism for accessing and transforming non-verbal, non-conscious self-experience. While both approaches utilize BLS, they are grounded in divergent theoretical assumptions regarding the nature of self-experience and the primary targets of therapeutic processing.
EMDR is a well-established, empirically supported trauma treatment that focuses on reprocessing discrete traumatic memories and their associated negative cognitions, affects, and somatic responses (Shapiro, 2017). Its protocol is organized around present-day beliefs about the self that are linked to specific target incidents, with the aim of reducing distress and facilitating adaptive information processing related to those memories.
SMBT, by contrast, is oriented toward identifying and working with more enduring, relationally encoded self-meanings that may predate explicit autobiographical memory and extend beyond any single traumatic event. Rather than targeting a specific incident and its associated belief, SMBT focuses on the lived, phenomenological experience of a dominant self-referential meaning, or SM (e.g., “I’m worthless”), including its emotional, somatic, imagistic, and symbolic expressions. Bilateral stimulation is then used to facilitate access to, and processing of, this experiential Self-Meaning at a non-conscious level.
The extended comparison with EMDR is included here to clarify points of theoretical and procedural divergence rather than to establish clinical superiority. Both approaches share important commonalities, including an emphasis on trauma-informed care, attention to somatic and affective experience, and the use of BLS to facilitate processing. However, they differ in what is treated as primary: EMDR centers on incident-linked memory networks and current self-beliefs, whereas SMBT centers on enduring self-meanings that organize experience across time and relational contexts.
To illustrate this distinction, consider a patient with a history of childhood abuse who reports persistent distress related to a specific traumatic memory. In EMDR, treatment may focus on reprocessing that memory, the associated negative cognition (e.g., “I am powerless”) and the distress it evokes, often resulting in meaningful symptom reduction and improved present-day functioning.
In SMBT, clinical inquiry may reveal that across multiple memories and relationships, the patient holds a more pervasive experiential Self-Meaning (e.g., “I’m worthless”). In this case bilateral stimulation is directed toward the phenomenological experience of this Self-Meaning itself—its emotions, bodily sensations, and symbolic representations—rather than toward a single incident. Following such processing, patients may report a reduction in the centrality of this Self-Meaning and a corresponding shift in how the self, as well as current relationships, are experienced.
These differing emphases suggest that EMDR and SMBT may be complementary rather than competing approaches. EMDR may be particularly effective for resolving distress linked to identifiable traumatic events, while SMBT may offer an avenue for working with more global, comprehensive, relationally embedded self-experiences that persist despite successful incident-focused processing.
