Conversation

Trilogy on SIB

Three-part conversation based on the study 'Child and Family Characteristics as Predictors of the Severity of Self-injurious Behaviours in Autistic Children and Adolescents' (2026): what SIB is, what the brain wants in therapy, and what it doesn't want.

PART I - What is this study about?

brain

The study examines self-injurious behaviours (SIB) in 594 children and adolescents on the autism spectrum.

me

Wait. What exactly is SIB?

brain

These are behaviours where a child disrupts their own physical integrity: head-banging, hand-biting, scratching until wounds form. Their function isn't destruction but regulation. Most often they serve as an emergency regulatory mechanism when the nervous system finds no other way.

me

Okay. So what we heard in lectures: the 'heavier' the #autism, the more SIB. The study probably doesn't change that?

brain

No. According to the study, the severity of autistic traits was not a predictor of SIB.

me

Oh?... Maybe then intellectual level?

brain

Also no significant connection. Cognitive functioning did not explain SIB severity.

me

I give up, so what actually mattered?

brain

Most strongly associated with SIB severity were: - sensory avoidance, - sleep problems, - reduced psychological wellbeing of the mother, - lower educational level of the father.

me

And I already see how someone will reduce this to 'parental blame'... though it's not about blame, but conditions and burdens.

brain

Yes. These are elements of the system in which the child functions, not an assessment of people. The study shows where burden accumulates, not 'who is at fault'.

me

The article also mentions that the model explains 'about 15% of variance'. What does that mean?

brain

It means this set of factors explains part of the differences in SIB severity between children, but definitely not all. The remaining 85% is complex reality: biology, experiences, pain, illnesses, environmental changes and current state of the organism.

me

So that's little or a lot?

brain

In studies on behaviour, this is typical, valuable result. It's a risk map, not an algorithm predicting an individual child's fate.

me

Summarize it for me? In one sentence?

brain

SIB is a regulatory and systemic phenomenon, not a characteristic of autism.


PART II - What does the brain want in therapy

me

Since this isn't 'bad #behaviour' but overload of the regulation system, I'll ask directly: what do you actually expect from therapy?

brain

Above all, I'd like resistance not to be confused with lack of willingness. Most often it means current demands exceed my resources.

me

So the key is cost?

brain

Yes. Every action should first be evaluated for energetic burden, and only then for conceptual appeal. If something overwhelms me, it doesn't become a strategy, it becomes another problem.

me

What about therapeutic goals? Every therapy starts with them, right?

brain

Yes. And then I often have emptiness in my head and grab the first available thought. Goals only make sense after basic stability is restored. When sleep-deprived, sensory-overloaded or under long-term tension, every goal is perceived as pressure.

me

So sleep really makes a difference?

brain

Huge difference. Sleep is a fundamental #RegulatoryIntervention, not the backdrop of daily life. Without it, the overload threshold drops dramatically.

me

And sensory aspects?

brain

First reduce stimulus load, then expect learning. In constant escape mode I don't have space for new skills.

me

Motivation?

brain

I don't need additional motivation. I need functional accessibility. When something is within my energetic reach, I do it without pressure.

me

And the system: school, procedures?

brain

Let it stop producing #RegulatoryDebt that later returns as behaviour (it doesn't disappear). It simply manifests later, usually at home after school, not because 'it's safe' but because the system has nothing left to 'regulate from'.

me

In one sentence, what kind of therapy is okay for you?

brain

One that first reduces life cost, and only then looks at what happens with behaviour.


PART III - What the brain DOESN’T want in therapy

me

Since we already know what helps, I'll ask directly: what do you definitely NOT want in therapy?

brain

I don't want therapy to add burden and then interpret my reaction as a problem.

me

Specifically?

brain

I don't want starting with demands, without checking if I have resources for them.

me

So goals before regulation?

brain

That's reversed order. Regulation isn't a means to an end, it is the end itself, and only on that foundation can we build what comes next.

me

What else increases cost?

brain

Ignoring sleep. With chronic sleep deprivation every subsequent intervention just deepens chaos.

me

And sensory environment?

brain

I don't want 'learning to function' in conditions that are unbearable for me. Stimulus reduction is a condition, not a privilege...

me

Motivating during crisis?

brain

Useless. At zero accessibility no reward system works.

me

So pressure, consequences, labels?

brain

I don't want language that judges instead of explains. Moralizing closes dialogue and increases cost.

me

And 'consequences'?

brain

Consequences that don't account for my state escalate rather than teach.

me

In one sentence?

brain

I don't want therapy that treats regulation as an add-on and behaviour as the main problem.


PS. This is a dialogue based on findings from the study and their implications for practice, not a literal summary of the article.
