The Standard Protocol of eye movement desensitization and reprocessing (EMDR) therapy uses 2 measures: subjective units of disturbance (SUDS) and validity of cognition (VOC). Both are rated at assessment. SUDS is taken again when the target seems cleared; a reading of zero or one permits the move from desensitization to installation. It is also retaken at re-evaluation. VOC is rated again at installation and, once a target has reached installation, at re-evaluation. By the close of successful processing, disturbance is expected to be low and conviction high. In practice, this is sometimes not what happens: SUDS falls while the positive cognition still does not feel true, or the cognition begins to feel true while disturbance does not diminish. Drawing on affective neuroscience (Panksepp, Solms) and predictive processing (Friston, Seth), this paper proposes that the 2 scales index processes with different relationships to time. SUDS indexes the affective activation maintaining temporal collapse, a state in which past threat is experienced as present and the future as unreachable. VOC indexes the degree to which the predictive apparatus has opened toward temporal extension, the condition under which a positive cognition can be felt as true. That the 2 have distinct neurobiological bases is held as a hypothesis and developed at the predictive and phenomenological level. Panksepp’s primary emotional systems are read by the temporality each produces as well as by their motivational profile. Divergence between the scales is then clinically informative rather than a procedural problem. Four implications follow, including a reading of the widespread omission of VOC under high disturbance as an enactment of the client’s temporal position.
The expansion of eye movement desensitization and reprocessing (EMDR) therapy into group formats has created a need for greater conceptual clarity regarding how trauma can be organized and processed within group contexts. This paper presents a theoretical framework underlying the EMDR Group Traumatic Episode Protocol, conceptualizing trauma not as a single discrete event but as a temporally extended Trauma Episode, understood as a continuum of experience, comprising interconnected past experiences, present triggers, and anticipated future concerns. Grounded in the adaptive information processing model, this framework identifies a multitarget processing structure organized around points of disturbance (PoDs), representing discrete yet interconnected elements within a broader associative trauma network. A central construct, termed microprocessing, describes the self-directed and circumscribed engagement with one PoD at a time. It is proposed to regulate the amount and associative range of traumatic material activated while supporting progressive integration across the Trauma Episode. Within the group EMDR context, PoDs are identified through guided introspective procedures, creating an iterative target-identification and sequencing structure without requiring clinician selection of each target. This does not replace screening, risk assessment, or determination of suitability for group participation. The approach supports a model of EMDR group intervention as a structured form of guided self-help while retaining the need for trained facilitation, clinical governance, and appropriate referral pathways. The model extends existing EMDR theory by addressing the temporal and cumulative nature of trauma and provides a conceptual basis for multitarget processing and scalable group intervention.
