Occupational Therapy for Autism
On this page
Direct answer
Autism changes how a child meets people, places and sensation — persistent differences in social communication paired with restricted, repetitive patterns of behaviour, interests or sensory responses, present from early development and graded in DSM-5 across three severity levels by support need. Occupational therapy targets the participation consequences: sensory over- and under-responsiveness, transitions and routine dependence, play and peer skills, feeding and toileting routines, and communication access through visual structure and augmentative systems. Assessment in India carries a native instrument — the Indian Scale for Assessment of Autism from NIEPID, Secunderabad, with a cut-off around 70 — alongside the Childhood Autism Rating Scale and ADOS. Structured teaching (TEACCH), the Picture Exchange Communication System, social stories and sensory integration form the intervention backbone, with National Trust schemes — Disha, Niramaya — behind the family.
What you must remember
- DSM-5's two domains: persistent deficits in social communication and social interaction, plus restricted, repetitive patterns — stereotyped movements, insistence on sameness, intense restricted interests, and hyper- or hypo-reactivity to sensory input (a DSM-5 addition, now examinable).
- Severity levels 1, 2 and 3: reflecting support needed, not intelligence — "high/low functioning" is loose language the viva should not hear.
- Indian Scale for Assessment of Autism (ISAA): a 40-item observer rating from NIEPID Secunderabad; commonly quoted bands run from about 70 (cut-off) upward, with roughly 70-106 mild, 107-153 moderate and 154-plus severe — the answer Indian examiners want named.
- CARS: 15 items, score of 30 or above indicates autism — the other classic viva number.
- PECS has six phases: from physically exchanged single pictures for requests, through discrimination and sentence strips, to commenting and responsive use — communication before speech, never instead of it.
- TEACCH structure: physical organisation of space, visual schedules, work systems with clear beginnings and ends, first-then boards — structure is the teaching language.
- Sensory strategies: Ayres sensory integration for processing deficits plus sensory diets for daily regulation, matched to the child's profile rather than applied wholesale.
- Social stories: Carol Gray's first-person scripts that rehearse a specific situation (haircut, bus, festival) before it happens.
- Indian scaffolding: National Trust Act 1999 covers autism (with cerebral palsy, intellectual disability and multiple disabilities); Disha funds early intervention; Niramaya provides health insurance; the RPwD Act 2016 recognises autism spectrum disorder.
Building a morning for a four-year-old who cannot bear transitions
A four-year-old, non-speaking, screams through every change of clothes and refuses the school van, sits in the corner lining up steel glasses. The ISAA places him in the moderate band; a brief sensory profile shows over-responsiveness to touch and sound. The intervention is built on his language — pictures. A morning schedule goes up: six photographs in fixed order — wake, toilet, dress, breakfast, shoes, van — each posted into a finish pocket as it is done, so time becomes visible and endings tolerable. Dressing gets a first-then card (dress first, then the spinning top he loves), and the clothes lose the seams-and-tags battle. PECS begins at phase one: he hands a picture of juice to his mother and receives juice, taught by physical prompt faded over two weeks, then generalised to father and grandmother. The van refusal is treated as a story, not defiance — a script with photographs of the driver, the seat, the school gate, read nightly before a trial ride. Toileting gets its own visual strip. Mother is coached weekly — less talking, more showing, warnings before transitions — and morning screaming drops to protest-then-compliance within eight weeks, picture requests appearing where tantrums used to do the asking.
Where students slip
Three answers sink vivas. Calling echolalia meaningless noise — it is communication in its rawest form, to be shaped, not silenced. Missing the DSM-5 shift — sensory features are now part of the diagnostic criteria, not a footnote. And reaching for cure language: autism is managed and supported, not treated away, and any "recovery" claim deserves open scepticism. The Indian exam touch is naming ISAA with its cut-off when asked for an assessment scale — quoting only western tools reads as rote.
Frequently asked questions
What are the two DSM-5 diagnostic domains in autism?
Persistent social-communication deficits, and restricted, repetitive patterns of behaviour, interests or sensory responses, with severity graded 1-3 by support need.
What is the ISAA and its commonly quoted cut-off?
The Indian Scale for Assessment of Autism, a 40-item scale from NIEPID Secunderabad; scores around 70 and above indicate autism, with bands for mild, moderate and severe.
What is taught in the first phase of PECS?
To physically exchange a single picture of a desired item with a communication partner to obtain it — the request before any word.
What is a visual schedule?
A fixed, picture-based sequence of the day's events that the child manipulates, making time, order and transitions visible and predictable.
Which Indian law and schemes support persons with autism?
The National Trust Act 1999 with schemes such as Disha for early intervention and Niramaya health insurance, alongside recognition under the RPwD Act 2016.
