Strategy
The Interoception Curriculum, developed by occupational therapist Kelly Mahler, is a framework for teaching people to notice, identify, and respond to internal body signals: hunger, thirst, pain, heartbeat, temperature, muscle tension, bladder fullness, and emotional arousal. It is used in over 25 countries.
The logic is straightforward: if you cannot perceive your rising heart rate, tensing muscles, or clenching stomach, you cannot regulate before crisis. Interoceptive awareness underlies emotional regulation. For many autistic people, especially those with alexithymia, this foundation is unreliable. See Interoception in autism and Alexithymia and autism.
The curriculum differs from other self-regulation approaches in what it avoids. It does not teach people to appear calm or colour-code emotions for observers. It builds genuine internal awareness so people understand what is happening inside their own bodies and can respond on their own terms.
When it applies
The curriculum is designed for autistic people (and others with interoceptive differences) across age groups, though the published research focuses on school-aged children and adolescents (ages 9–19). It is delivered in school settings, clinical settings, and by trained carers at home.
It is most relevant for people who show signs of interoceptive difficulty: not recognising hunger until it’s extreme, not noticing the need for the toilet until it’s urgent, difficulty identifying emotions beyond “fine” or “not fine,” seeming blindsided by meltdowns without recognising the build-up, or having difficulty with self-care routines that depend on reading body signals.
How it works
The curriculum teaches interoceptive awareness through a structured sequence:
- Body awareness activities. Concrete exercises like noticing heartbeat before and after movement or identifying where feelings are located in the body. These are guided activities, not abstract discussion.
- Naming internal states. Building vocabulary for body signals (“tight,” “buzzy,” “heavy,” “fluttery”) without mapping them immediately to emotion labels.
- Connecting body signals to needs. Linking sensations to actions: “When my stomach feels hollow, I might need food. When my chest feels tight, I might need a break.”
- Building personal strategies. Developing a personal toolkit based on the individual’s body-signal map. What works for one person’s chest tightness may not work for another’s.
The approach is bottom-up, starting with body and moving toward cognition rather than beginning with abstract emotional concepts.
What the evidence shows
The first full-scale study was published in 2021 (PMC). Fourteen autistic students aged 9–19 participated in a 25-week school-based intervention. Results showed significant improvements in interoceptive awareness and emotion regulation.
This is a small study with no control group, limiting conclusions. However, it is the first to examine a self-regulation framework in its entirety with autistic participants and show positive results on validated measures. Compared to other self-regulation approaches (Zones of Regulation, for instance, does not meet evidence-based practice standards), it is a stronger starting point.
Broader interoception research supports the theoretical foundation. The link between interoceptive difficulty and emotion dysregulation in autism is well-documented. See Interoception in autism for the three-dimensional model (accuracy, sensibility, awareness) and evidence on interoceptive trait prediction error.
What to watch for
Signs it is working: The person beginning to notice and name body signals they previously missed. Earlier recognition of escalating states (catching “orange zone” before “red zone,” in prikkelbalans terms). Increased independence in self-care activities. The person spontaneously using body language to communicate their state.
Signs it is not: No change in body awareness after sustained engagement with the curriculum. Increased anxiety about body sensations (the curriculum should be calming, not alarming). The person finding the exercises aversive or confusing.
Known limitations:
- Metacognitive demands. The curriculum requires capacity to reflect on and report internal experience. For people with severe intellectual disability or minimal speech, the standard format may not be accessible. Visual supports and body-based activities exist as adaptations but have not been separately studied.
- Interoception-alexithymia interaction. People with both interoceptive difficulty and alexithymia may find it harder to bridge body sensation and emotional understanding. Progress may be slower.
- Limited evidence. The evidence base is promising but thin. Research is needed with larger samples, control conditions, and diverse populations including people with intellectual disabilities.
The intellectual disability question
This remains a critical open question for autistic people with intellectual disability. Approximately 70% of autistic people have co-occurring intellectual disability, yet curriculum research was conducted with verbally-engaged participants.
For people with more profound intellectual disability, support may look different: using timers for eating and toileting, incorporating body-awareness activities into physical routines, relying on carer observation of body-signal indicators. Some adaptations are described in the interoception literature but none have been formally studied.
The link between interoceptive difficulty and “challenging behaviour” in intellectual disability is important: people cannot communicate pain, hunger, or overwhelm, so behaviour becomes the signal. This area needs investigation.
Evidence notes
Evidence level: peer-reviewed (one full-scale study, supported by broader interoception research). The theoretical foundation is strong and grounded in autistic self-described experience. The intervention philosophy is explicitly not compliance-focused, which aligns with a neurodiversity-affirming approach.
Of self-regulation frameworks reviewed here, the interoception curriculum is most aligned with prikkelbalans: both centre the individual’s internal experience over external appearance.
