When It’s Not A Part: Understanding an OPI in Parts Work

Graphic representing Resource State theory, alongside a INtrojects and Other Personalised Introject (OPI), demonstrating the difference between parts of the personality and an internal presence experienced as not belonging to the self in Resource Therapy.

For therapists working with trauma, parts, and complexity

A Subtle and Critical Moment In Therapy

Sometimes in therapy, there’s a moment that doesn’t quite fit. You’re with a client. The work is flowing. And then something shifts.

The tone changes.
The language sharpens.
The energy feels… different.

And if you’re really attuned, there’s often a quiet internal signal:

“Hmm ..I’m not quite speaking to my client right now.”

It’s easy to dismiss. But clinically, this moment matters.

Because not everything that appears in a session belongs to the personality.

What Is Resource Therapy? (And Why This Distinction Matters)

Resource Therapy is an attachment-informed, trauma-focused, action-based parts therapy developed by Professor Gordon Emmerson.

It provides therapists with:

  • a clear map of which part is at the helm
  • a structured way to identify 8 clinical pathologies
  • 15 targeted treatment actions for direct intervention

Unlike many parts models, Resource Therapy is not just about insight.

👉 It is about knowing what to do next in the room

Not Everything Present Is A Part

In Resource Therapy, we work primarily with Resource States (parts). So do EMDR Therapists, CBT workers and ACT psychotherapists.

These are aspects of the personality that:

  • belong to the person
  • hold emotional and sensory experience
  • can be accessed, processed, and resolved

But here is the clinical edge:

👉 Not everything present in the system is a Resource State

And when we assume it is, we risk working in the wrong place.

What Is An OPI (Other Personalised Introject)?

An OPI (Other Personalised Introject) is:

an internalised “other” that is experienced as separate from the self, and not part of the personality system

This is where Resource Therapy differs from many other parts-based approaches.

Rather than treating all internal experiences as parts, RT distinguishes between:

  • Resource States (parts)
  • Introjects (internalised relational imprints)
  • OPIs (not part of the personality)

How To Recognise An OPI In Session

OPIs have a distinct clinical feel.

You may notice:

  • Third-person language
  • Feels like a Perpetrator
    • “She’s useless”
  • A rigid, repetitive voice
  • A strong sense of “this is not me”
  • An intrusive or “other” quality
  • A feeling that you are speaking to someone else

This is not metaphor.

It is a clinical observation.

Common Mistake: Treating Everything As A Part

Most therapists are trained to respond to internal experiences by:

  • exploring them
  • integrating them
  • or healing them

And often, this works.

But when the experience is actually an OPI:

👉 This approach can slow the work down significantly

You may notice:

  • circular conversations
  • lack of shift
  • client confusion
  • therapist uncertainty

Not because the work is wrong.

Because the target is wrong.

The Resource Therapy Parts Distinction

Resource Therapy brings clarity through structure:

Resource States (Parts)

  • Belong to the self
  • Hold emotion and experience
  • Can be healed and integrated

Introjects

  • Internalised relational messages
  • Held within a Resource State
  • Worked through the part that carries them

OPIs

  • Not part of the self
  • Experienced as “other”
  • Can be engaged and leave

👉 This distinction allows for precision-based therapy

What To Do When It’s Not A Part

When an OPI is identified, the clinical stance shifts.

In Resource Therapy, we:

  • clarify what is present
  • check whether it belongs to the client
  • engage it directly if needed using the OPI protocol
  • support its separation from the system

We do not:

  • treat it as a part
  • attempt integration
  • or process it as a trauma state

What Clients Experience After OPI Work

When this is done well, the shift can be immediate.

Clients often report:

  • a sense of internal quiet and a sense of feeling lighter, unburdened
  • increased clarity
  • reduced internal conflict
  • relief that feels disproportionate to the time spent

This is not insight-based change.

👉 It is a structural change in the system

Why This Matters For Trauma Work

For therapists working with:

  • complex trauma
  • attachment disruptions
  • dissociation
  • internal conflict

This distinction is critical.

Because precision:

  • reduces overwhelm
  • increases safety
  • accelerates resolution

Reflections of a Parts Therapist

In therapy, we are trained to ask:

👉 What is happening here?

Resource Therapy invites a more precise question:

👉 What is here… and does it actually belong to the system?

Because when we get that right:

The work becomes clearer.
Faster.
And deeply effective.

How Memory Reconsolidation Works in Resource Therapy

advanced parts therapy informed memory reconsolidation

Have you ever wondered why some sessions lead to deep, lasting shifts while others just produce better coping, you are already thinking about memory reconsolidation. This is the brain’s natural process for updating emotional learning – and it sits at the heart of effective, evidence-informed trauma therapy.

For therapists using parts-based, trauma-informed approaches such as Resource Therapy, understanding memory reconsolidation can help us work more precisely and confidently with the “emotional brain”.

What is memory reconsolidation in therapy?

Memory reconsolidation is the process by which an existing emotional memory becomes open to change. When a significant emotional memory is reactivated, there is a brief neurobiological window in which that learning becomes “plastic” again. If – and only if – a mismatching, corrective experience is introduced during this window, the old learning can be revised rather than simply layered over with new coping strategies (Ecker, Ticic, & Hulley, 2012; Lane, Ryan, Nadel, & Greenberg, 2015).

Clients often describe the result in simple language: “It’s strange – the old reaction just isn’t there in the same way.” For trauma, attachment wounds, and long-standing shame, this is profoundly hopeful.

How Resource Therapy uses memory reconsolidation

Resource Therapy (RT) is a parts-based, trauma-informed model that maps beautifully onto memory reconsolidation. Instead of treating the client as a single, unified self, RT works with Resource States – the inner “parts” or “crew members” who each hold specific emotional learnings from earlier experiences.

In practice, a reconsolidation-informed RT advanced parts session often involves four stages:

  1. Bringing the State “on deck”
    The first step is helping the relevant Resource State come fully into conscious awareness, with its feelings, beliefs, images, and body sensations. The old story – “I’m not wanted”, “It’s not safe to need anyone”, “The only way to be loved is to be perfect” – needs to be alive in the room.
  2. Bridging to the Initial Sensitising Event (ISE)
    Next, we follow that State back to the Initial Sensitising Event where its core learning formed. Using RT’s structured treatment actions, we locate the scene where the State drew its painful conclusion about self, others, or the world.
  3. Creating a mismatch experience
    At the ISE, we then create a new emotional experience that directly contradicts the old learning. The hurt State may finally feel protected instead of abandoned, validated instead of shamed, or comforted instead of terrified. This is more than talking about safety – the child-state actually feels accompanied, defended, and believed.
  4. Consolidating new learning with other Parts
    Finally, we help other, better-able parts step forward so that, in similar situations in present-day life, a different part can take the wheel. The client begins to notice: “I respond differently now.” This is emotional rewiring rather than short-term coping.

What are the Key principles of memory reconsolidation?

Although the neurobiology is complex, the clinical principles are straightforward:

  1. Reactivate the emotional memory – the original learning must be vividly present.
  2. Elicit a mismatch experience – the client needs a felt experience that clearly contradicts the old belief.
  3. Allow new learning to consolidate – we slow down, stay with the shift, and let the nervous system absorb this new reality.
  4. Integrate into everyday life – we notice and reinforce new patterns as they show up in relationships, work, and self-care.

Used thoughtfully and ethically, these principles mean we are not only teaching clients to cope. We are helping the brain update its deepest emotional scripts.

What this means for your practice

For many clinicians, “evidence-informed” means more than quoting a study or adding a brain diagram to our slides. It is about aligning what we do in the room with what we know about how change actually happens carefully, collaboratively, and within our scope of practice.

As you consider your professional development for the year ahead, you might like to ask: where in my work am I offering true emotional rewiring, and where am I mainly helping clients manage?

If you are curious about parts-based, memory-re consolidation-aligned ways of working, Resource Therapy offers a clear, humane framework for doing just that. Training with Master clinicians Chris and Philipa (President of Resource Therapy International) at the Australia Resource Therapy Institute in 2026 is one pathway to deepen this work.
