EMDR, AIP and Veteran Transition: A Clinical Perspective
Leaving military service can involve changes in work, relationships, identity and support. Some veterans also experience trauma-related distress during this period. The Adaptive Information Processing (AIP) model offers one clinical framework for thinking about distressing memories; it does not establish why symptoms emerge at a particular time for an individual veteran.
How AIP explains military trauma
In the AIP model developed by Francine Shapiro, distress is understood in relation to memories that have not been adequately processed. This is a treatment framework, not proof that military service stores memories in a particular biological state. The mechanisms underlying EMDR remain under study.
Considering the transition context
Changes in routine, relationships and support may matter when assessing a veteran’s distress after service. The clinician should explore the person’s history and current circumstances rather than assume that leaving the military has released previously stored trauma.
Moral injury inside the model
Moral injury can be relevant to a veteran’s presentation. VA describes distress following events that violate deeply held moral beliefs, and notes that it can occur with or without PTSD. Guilt, shame or betrayal may therefore need attention in case formulation. PTSD treatment evidence should not be treated as proof of a moral-injury-specific outcome.
Considering EMDR for PTSD
EMDR is a recommended psychotherapy for PTSD. Its fit for a particular veteran depends on assessment, preferences and clinical circumstances. The VA notes that much of the research was conducted in civilian samples and that more military- and veteran-specific research is needed; the evidence does not establish that EMDR uniquely matches military learning styles or identity.
An individual formulation
AIP may help organize a formulation, but difficulties during transition should not automatically be attributed to a memory-processing problem. Assessment can consider trauma symptoms alongside sleep, relationships, employment and other current needs.
