Overview

What Is the Adaptive Yearning Model?

Grief therapy has long treated yearning as a symptom to be resolved. The AYM proposes something different: yearning is the attachment system doing exactly what it was designed to do.

The Adaptive Yearning Model (AYM) is an original clinical framework proposing that yearning β€” the somatic and relational longing for a deceased attachment figure β€” is a normative, adaptive response to loss rather than a marker of complicated or pathological mourning.

Grounded in Bowlby's attachment theory (1980), continuing bonds theory (Klass et al., 1996), the Dual Process Model (Stroebe & Schut, 1999), grief neuroscience (O'Connor, 2019), meaning reconstruction theory (Neimeyer, 2019), and polyvagal theory (Porges, 2011), the AYM integrates neurobiological and somatic perspectives to describe how grieving individuals process loss through the body, the relational field, and the adaptive nervous system.

The AYM is the theoretical foundation for the Grief Map framework β€” a dimensional clinical system integrating EMDR therapy's eight-phase protocol with the ADEC grief domain taxonomy. The two frameworks are being explored empirically through the Grief Map Pilot Study, currently underway.

Core Concept

Adaptive Yearning vs. Frozen Yearning

The clinical question the AYM is built to answer is not whether a client is yearning. Most bereaved people are. The question is whether the yearning is moving.

Bonanno's resilience research (2004) established that most bereaved people process loss adaptively over time without formal intervention. Stroebe and Schut's Dual Process Model (1999) named the mechanism: oscillation. Healthy grieving involves movement between loss-orientation and restoration-orientation. The AYM positions adaptive yearning within this oscillatory arc.

When oscillation stops and yearning becomes fixed, pervasive, and impairing, the clinical threshold of Prolonged Grief Disorder (DSM-5-TR, APA, 2022) may have been crossed.

Adaptive Yearning

  • Oscillates in intensity
  • Accessible without overwhelming dysregulation
  • Integrates into continuing bonds
  • Permits moments of restoration-orientation
  • Moves toward meaning reconstruction
  • Does not require formal intervention

Frozen Yearning

  • Fixed and constant in intensity
  • Dysregulating and overwhelming
  • Blocks restoration-orientation
  • Functionally impairing
  • Resists integration over time
  • Indicates clinical intervention is warranted

"Yearning that oscillates β€” that the grieving person can feel and also set down, return to and then step away from β€” is healthy grief doing exactly what it should. Yearning that has stopped moving is where clinical attention is required."

Theoretical Grounding

Six Foundational Frameworks

The AYM integrates six theoretical traditions, each selected because it addresses a dimension of grief that the others cannot fully reach.

01

Attachment Theory

Grief is biologically organized. The attachment system does not distinguish between temporary separation and permanent loss β€” yearning is its adaptive protest response.

Bowlby (1980)
02

Continuing Bonds

Maintaining ongoing relationships with the deceased is normative and healthy. Yearning is the somatic expression of bonds that continue beyond death.

Klass, Silverman & Nickman (1996)
03

Dual Process Model

Adaptive grief oscillates between loss-orientation and restoration-orientation. Oscillation is the mechanism β€” not linear stage progression.

Stroebe & Schut (1999)
04

Grief Neuroscience

Yearning activates the nucleus accumbens β€” the brain's attachment and reward circuitry β€” not pain pathways alone. The reaching is neurobiologically meaningful.

O'Connor (2019)
05

Meaning Reconstruction

Grief reorganizes narrative identity. The AYM positions yearning as the somatic leading edge of meaning reconstruction β€” the body holding what narrative has not yet integrated.

Neimeyer (2001, 2019)
06

Polyvagal Theory

Two nervous systems are present in every grief session. The clinician's co-regulatory presence is the neurobiological condition that makes safe processing of yearning possible.

Porges (2011)
Framework Architecture

Six Core Propositions

The AYM rests on six propositions that together constitute its theoretical claim:

  1. Yearning is an adaptive, neurobiologically organized response to the absence of an attachment figure β€” not a symptom of grief dysfunction. Bowlby (1980); O'Connor (2019)

  2. Continuing bonds with the deceased are normative and healthy. Yearning is one primary somatic expression of those bonds. Klass et al. (1996)

  3. Adaptive yearning is characterized by oscillation β€” the capacity to move into and out of the felt experience of longing within a regulated window of tolerance. Stroebe & Schut (1999)

  4. Yearning is the somatic leading edge of meaning reconstruction. When yearning is metabolized, the narrative work of rebuilding the assumptive world becomes accessible. Neimeyer (2001, 2019)

  5. When the grief network remains accessible, adaptive information processing occurs naturally over time. Clinical intervention supports rather than directs this process. Shapiro (2001, 2018)

  6. The clinician's co-regulatory presence β€” grounded in polyvagal attunement and felt sense awareness β€” is the primary mechanism through which safe adaptive processing becomes possible. Porges (2011); Gendlin (1978)

Empirical Investigation

Research Status

The AYM is a theoretical and clinical framework. It does not precede empirical investigation β€” it generates it. A peer-reviewed paper on the AYM has been submitted to Death Studies. The framework is being explored empirically through the Grief Map Pilot Study, currently underway.

Active Research

Grief Map Pilot Study β€” Cohort 1

The pilot study examines the clinical utility and preliminary feasibility of the Grief Map framework β€” which integrates the AYM with EMDR therapy's eight-phase protocol β€” with EMDR-trained grief therapists. Data collection is underway across two training sessions in May and July 2026.

The study uses a pre-post design with proposed instruments including the Adaptive Yearning Scale (AYS), Dimensional Grief Scan (DGS), and Relational Grief Field Inventory (RGFI). No outcome claims are advanced at this stage.

The AYM and the Grief Map

The AYM is the theoretical foundation of the Grief Map clinical system, which integrates three instruments:

  • The ADEC grief domain taxonomy β€” six content themes examined through ten dimensional lenses, functioning as a target selection architecture
  • EMDR therapy's eight-phase protocol β€” the processing mechanism (Shapiro, 2001, 2018)
  • The Adaptive Yearning Model β€” the theoretical bridge describing what is happening in the grief and the nervous system as the three-layer system operates
