SUD and VOC in EMDR: How to Track Ratings Across a Session

What SUD and VOC Track in EMDR

SUD and VOC ratings give EMDR therapists a structured way to follow change across a target.

SUDS, or Subjective Units of Disturbance, captures how distressing the target feels right now. It is usually rated from 0 to 10. A 0 means no disturbance, while a 10 means the highest distress the client can imagine or tolerate naming.

VOC, or Validity of Cognition, captures how true the positive cognition feels right now. It is usually rated from 1 to 7. A 1 means the statement feels completely false, while a 7 means it feels completely true.

CoralEHR's free SUD/VOC Tracker lets trained EMDR clinicians record baseline ratings, changes between BLS sets, installation ratings, closure status, and a plain-text session summary.

Why Tracking Matters

EMDR sessions move quickly. A client may begin with high disturbance, report images or body sensations that shift after several sets, then need containment or closure before the target is fully resolved. Without a structured record, it is easy to lose the exact sequence.

Tracking helps the therapist remember:

• the target label and related negative cognition
• the intended positive cognition
• the starting SUD and VOC
• meaningful shifts after BLS sets
• body sensations or new material that emerged
• closure status and next-session needs

The ratings are not the whole clinical story. They are anchors that help organize the story.

When to Record Ratings

Target Setup

Record the target label, negative cognition, positive cognition, starting SUD, starting VOC, emotion, and body location when those elements are part of the protocol being used.

Keep labels de-identified. For example, "car accident target" is safer than a full narrative with names, locations, and dates.

Between BLS Sets

Between sets, the therapist may capture SUD, VOC, client report, body sensation, or short process notes when clinically useful. Some sets only need a brief observation. Others may produce enough change that a rating helps preserve the flow.

Avoid turning every set into a long questionnaire. The tracker should support the work, not interrupt processing.

Installation

When the disturbance has reduced and installation is clinically appropriate, record the VOC for the positive cognition. This helps show whether the adaptive belief is strengthening rather than only noting that distress decreased.

Closure

At the end of the session, document whether the target was complete, incomplete, contained, or planned for reevaluation. If the target is incomplete, note the stabilization or containment strategy used.

Reevaluation

At the next session, reevaluate the target and compare current SUD/VOC to the prior closure state. This is often where a clean summary is most useful.

Example EMDR Tracking Flow

A simple session record might include:

• Target: de-identified accident memory
• Negative cognition: "I am not safe"
• Positive cognition: "I am safe now"
• Baseline SUD: 8
• Baseline VOC: 2
• Set 1: SUD 7, image shifted, chest tightness
• Set 2: SUD 5, more distance from image
• Set 3: SUD 3, sadness increased briefly
• Closure: incomplete target, container exercise used, follow-up planned

That summary gives the therapist enough continuity for the next appointment without over-documenting every detail.

Documentation Example

Use concise clinical language:

Therapist used EMDR SUD/VOC tracking during processing of de-identified target. Client reported baseline SUD 8/10 and VOC 2/7 for selected positive cognition. Across BLS sets, client reported reduced disturbance to SUD 3/10 with shifting body sensation from chest tightness to neutral. Target remained incomplete at end of session; therapist completed containment and grounding. Reevaluation planned next session.

Avoid making unsupported claims:

EMDR tracker proves trauma memory is resolved.

SUD and VOC ratings are subjective clinical data. They should be interpreted with client report, observed regulation, protocol stage, risk context, and therapist judgment.

Safety and Scope

A SUD/VOC tracker is for trained EMDR clinicians. It does not decide readiness, select targets, manage dissociation, prescribe interweaves, or determine whether EMDR is appropriate for a client.

Use extra caution when clients have active safety concerns, complex dissociation, unstable living situations, acute substance use concerns, medical vulnerability, or trauma material that requires more stabilization before processing.
