Where it comes from
The ideal parent figure protocol was developed by Daniel P. Brown, a Harvard Medical School professor and clinical psychologist, and David Elliott, a licensed clinical social worker, over decades of attachment research and clinical practice. Their landmark book, Attachment Disturbances in Adults: Treatment for Comprehensive Repair (2016), is one of the most thorough treatments of adult attachment healing in the literature.
Brown’s work was grounded in several converging bodies of research:
Neuroplasticity. The brain does not stop forming new neural pathways in adulthood. Repeated, emotionally vivid experiences — including imagined ones — can establish new relational templates. The nervous system learns from felt experience, not from intellectual understanding.
Earned security. Studies of adults who were insecurely attached in childhood but became securely attached in adulthood consistently show one thing: meaningful relational experiences that provided what early relationships didn’t. Brown’s protocol creates these experiences in imagination — and the nervous system, with repetition, treats them as real.
Interpersonal neurobiology. Daniel Siegel’s work shows that relationships literally shape brain structure — particularly the circuits involved in emotion regulation, self-awareness, and attunement. The IPF practice creates a relational experience (even an imagined one) that exercises exactly those circuits.
The five qualities of ideal parental presence
Brown’s research identified five things that securely attached children receive from caregivers — and that adults with insecure attachment need to internalise at a felt, bodily level.
1. Felt safety
Not just the absence of danger, but the positive, physical sense that I am safe here. This person’s presence itself communicates: you are protected. The nervous system can settle. The scanning can pause.
2. Being seen and known
Not seen for your performance, or for the version of yourself you present, but for you — your inner life, your real feelings, your actual self. Being witnessed without the witness being overwhelmed or frightened by what they see.
3. Felt comfort
When you are in pain, the caregiver moves toward you, not away. They can hold your distress without shutting it down, fixing it prematurely, or being destabilised by it. You learn that emotional pain is survivable, and that others can stay present with you through it.
4. Expressed delight
Someone who genuinely lights up when they see you. Not because of what you’ve done or achieved — but simply because you exist. This is one of the most powerful and often most unfamiliar qualities in the practice.
5. Support for becoming yourself
A caregiver who has no agenda for who you should be — who actively encourages your individuality, your interests, your unique way of being in the world. Who celebrates your becoming, rather than shaping it toward their own needs.
