After Greenspan: Reimagining DIR in a World of Real Dependency
From developmental optimism to interpretive responsibility
DIR (Developmental, Individual-differences, Relationship-based) changed the field by insisting on something radical at the time: development does not unfold in isolation.
It unfolds in relationship.
It unfolds in time.
It unfolds through engagement rather than compliance.
Intervention within DIR was therefore never meant to be corrective or rehabilitative. It was meant to support the developmental process, not fix a child.
This shift was paradigmatic: DIR directly challenged the prevailing behavioral paradigm in the treatment of neurodevelopmental conditions. It continues to do so, while also leaving important questions unanswered.
But after Dr. Stanley Greenspan’s death in 2010, something else became visible. Greenspan was not only the originator of DIR; he was its generative force. He built institutions to disseminate the model, founded publishing and training infrastructures, and produced an extensive body of peer-reviewed work and books that gave DIR its conceptual momentum.
Fifteen years later, the research base explicitly using DIR as methodology remains small. While our understanding of the neurobiology of autism continues to grow, and while relational support is increasingly recognized as central to human development, empirical work linking relational developmental models to long-term outcomes for autistic individuals remains limited.
This is not a dismissal of DIR.
It is an invitation to re-situate its strengths within what we now understand about developmental science and the lived needs of autistic individuals.
DIR helped us see that development is a dynamic process, shaped both by internal organization and by relational context, rather than the linear acquisition of skills. It emphasized affectively organized engagement as the primary experiential mediator of this process and resisted fragmenting the child into workable parts.
But DIR also inherited a cultural assumption it never fully questioned: that development is ultimately oriented toward independence and typicality.
In practice, this assumption appears when:
limits are treated as contextual rather than structural
affect is implicitly assumed to eventually reorganize all capacities
caregivers are implicitly asked to “do more” when progress stalls
relationship becomes the default solution to real neurodevelopmental constraints
This is not because DIR is naïve.
It is because DIR never fully theorized dependency.
Greenspan did not have the luxury of questioning everything. DIR was born into a field that urgently needed humanization, not further theorization of limitation. Today, the landscape has changed. The work of disability scholars and advocates, especially those speaking from the realities of individuals with extremely high support needs, has made it possible to name dependency without erasing dignity or possibility. A post-DIR model must take responsibility for asking the questions DIR could not afford to ask at the time.
In much of developmental thinking, dependency is treated as something children grow out of, something relationship temporarily supports and skill acquisition eventually resolves.
But in neurodevelopmental disability, dependency is often structural.
Some individuals will require, most of the time:
assistance with regulation
support for participation
scaffolding for communication
relational mediation to access the world
This is not a failure of development.
It is a feature of human variation.
The problem is not dependency.
The problem is pretending it is temporary when it is not.
To move forward, a different conceptual move is needed.
In physics, Einstein introduced the speed of light as a constant, not because everything moves at that speed, but because all motion must be understood in relation to it.
A post-DIR model needs something similar.
Dependency is not:
a deficit to eliminate
a problem to fix
a sign that engagement failed
It is a reference condition.
The question is not whether dependency exists, but how much, in what domains, under what conditions, and at what cost.
Neurodevelopmental constraints, neurological, sensory, motor, cognitive, determine the degree and form of dependency. They do not erase development itself.
Once dependency is acknowledged as structural rather than temporary, development can no longer be read through outcome alone. There is no neutral metric that tells us whether a trajectory is “successful,” no automatic endpoint that resolves uncertainty.
What remains is interpretation: decisions about what counts as participation, dignity, progress, or harm over time.
A post-DIR model therefore demands interpretive responsibility, not from families alone, but from clinicians, researchers, and systems. It requires taking responsibility for how developmental difference is read, where limits are named, and where expectations are imposed or released.
This is the shift from developmental optimism to interpretive responsibility.
What Changes When Dependency Is a Constant
Once dependency is treated as a constant rather than an anomaly, several things shift.
1. Development stops meaning “catching up”
Development becomes oriented toward quality of life: increased coherence, reduced suffering, expanded participation, and greater agency within real constraints.
Progress is no longer measured by proximity to typical milestones.
2. Relationship stops being romanticized
Relationship is no longer treated as the answer to all constraints or as an infinite responsibility caregivers must continually refine.
It is recognized as what it actually is: a powerful modulator of the developmental process, one lever among several that can support or strain developmental potential.
This is imperative because it relocates responsibility from constant relational optimization to a broader understanding of development as multi-determined, bounded, and shared.
3. Care becomes visible labor
Dependency requires work: emotional, physical, temporal, cognitive.
A post-DIR model makes this work visible and recognizes it as a shared social responsibility, rather than leaving it invisible, unqualified, and endless.
DIR does not disappear.
It is reassigned.
DIR becomes a way of interpreting development in dialogue with developmental science, rather than a total explanatory theory of it.
It offers a disciplined way of reading engagement, collapse, recovery, and participation over time. It constrains practice ethically and clinically by asking:
Is engagement present or collapsed?
Is participation expanding or becoming more costly?
Are interventions supporting meaning or merely producing output?
Are we respecting the child’s system rather than imposing a norm?
DIR does not deny neuroscience.
It does not erase limits.
It does not promise normalization.
Being human means interdependence.
Autism does not create dependency.
It reveals forms of dependency that were always present in human life—but unevenly distributed, privately managed, and socially hidden.
A just developmental model does not ask how to eliminate dependency.
It asks how to recognize it without shame, share its costs, and preserve dignity within it, for individuals and for the families who sustain them.
A post-DIR paradigm holds all of this at once:
real neurodevelopmental constraints
open-ended developmental processes
permanent and variable dependency
relationship as support, not salvation
care as shared responsibility, not private virtue
This is not less hopeful.
It is more truthful.
And truth is what families, clinicians, and disabled individuals have been asking for all along.
