The Theory of Change Behind PDA Accommodations: Why Lowering Demands Is Not Enough | Ep. 184

Why do accommodations like lowering demands, providing autonomy, and using declarative language actually work for PDA children and teens over the long term? And why do so many parents, therapists, and teachers get stuck applying them even when they understand the concept?

In this episode, an excerpt from a live workshop I taught in 2024, I walk through what I call the theory of change for PDA: the logic that explains why these accommodations shift things at a nervous system level. I cover the two most common places where people get stuck, how to tell the difference between an accommodation and a reward, and why lowering demands alone is necessary but not sufficient for the transformation families are working toward.

 Key Takeaways

• What Accommodations Are Actually Doing in the Nervous System | 00:00:00 Accommodations for PDA children and teens serve three functions. They keep the child in the thinking brain rather than the survival brain, where learning, empathy, cause and effect, and connection can actually happen. They create new neural pathways back to the thinking brain over time, so the nervous system has more options than dysregulation. And they bring down cumulative nervous system activation below the threshold of tolerance so that the behaviors of avoidance, opposition, and shutdown begin to reduce. None of this happens in a single session or a single week. It is a long-term, cumulative shift in the opposite direction from the long-term, cumulative activation that brought the family to this point.

• The Most Common Sticking Point One: Removing Accommodations When Things Improve | 00:04:01 My son is out of burnout. He plays tackle football. He is thriving at a private school and we are doing things as a family again that we could not do for years. I am still bringing him food on the couch while he watches his iPad. I am still intensively accommodating him. That is not a contradiction. It is the reason things are going well. When families remove accommodations because the child seems regulated, the cumulative nervous system activation begins to build again, and what looked like progress reverses. The accommodations are what is keeping his nervous system below the threshold. They do not disappear when things improve. They are what made things improve.

• The Most Common Sticking Point Two: Using an Accommodation to Get a Behavior | 00:07:32 When I first learned declarative language, I started saying things like I noticed you still have apples on your plate, but the energy behind it was to get my son to eat the apple. A PDA nervous system can detect that. The amygdala is always scanning for whether someone is placing themselves above as the decider, and it will pick up on the intention underneath the words even when the words have changed. An accommodation used to achieve compliance is not an accommodation. It is a repackaged demand. This is one of the most common places I see families getting stuck even after months of learning the framework.

• The Transition Treat: Accommodation Versus Reward | 00:09:09 My son gets a Twix before every car transition to school, regardless of whether he gets in the car. That is an accommodation, not a reward. A reward is contingent on compliance: do the thing, get the treat. An accommodation is given regardless: here is a dopamine support for this moment of transition, whether or not you can get in the car today. The distinction matters because a contingent reward carries the energy of an expectation, which activates the PDA threat response. A non-contingent accommodation does not. This is one of the clearest practical examples I have of what the shift from behavioral to autonomy-based logic actually looks like in daily life.

• Lowering Demands Is Necessary but Not Sufficient | 00:11:00 Lowering demands is a powerful and necessary starting point, but it is not the whole picture. What I have seen across hundreds of families is that the full transformation, the one where the relationship shifts from avoidant and oppositional to collaborative and trusting, requires both the baseline of accommodation and the shift in the relational dynamic. A child or teen who feels genuine felt safety on a subconscious level, who trusts that the adult will not push them past their threshold, is a child who can eventually begin to lead their own learning, try new things, and ask for help. That trust is built through consistency over time, not through any single accommodation or technique.
