Therapy Options — Evidence at a Glance
An evidence-ranked tour of the main therapy approaches for autism, plus the six questions to ask before starting any therapy.
Parents are offered a dizzying list of therapies after a diagnosis. The most useful framing is evidence classification: scientifically based → promising → limited → not recommended. This tour comes from a children's development center's parent packet, which classified twelve therapies using a published review plus clinical judgment.
The evidence-ranked tour
| Therapy | Type | Classification |
|---|---|---|
| ABA (Applied Behavior Analysis) | Skill-based | Scientifically based; highly recommended — see the contested-topic note below |
| TEACCH | Skill-based curriculum | Promising practice |
| PECS | Skill-based (communication) | Promising practice |
| Sensory Integration (OT) | Biologically based | Promising; possibly better for younger children |
| Social Stories | Cognitive | Promising practice |
| Floortime (DIR) | Relationship-based | Limited supporting information |
| RDI | Relationship-based | Limited supporting information |
| Music / art / animal therapy | Relationship-based | Limited evidence for treating autism; valued for self-esteem and relationships |
| Prescription medications | Biological | No medication treats core autism; symptom-targeted only, specialist-managed |
| Vitamins & supplements | Biological | Little/no supporting research; some can be toxic |
| Dietary interventions (GF/CF, yeast-free) | Biological | Not scientifically based; malnutrition risk — work with a doctor/nutritionist |
| Heavy metal detox (chelation) | Biological | Not recommended — can be harmful; child deaths reported |
The six questions to vet any therapy
Before starting any approach — especially ones recommended by well-meaning friends or promoted online — run it through these:
- Could the therapy harm my child in any way?
- Will it cause undue hardship on my family?
- Is it scientifically based and widely accepted?
- How will success be measured?
- Am I learning so I can work with my child at home?
- Is the person qualified to do the therapy?
A note on contested topics
ABA is the most-researched behavioral approach and is highly recommended by major clinical bodies — but it is also the subject of an ongoing debate within the autistic community, with many self-advocates describing harmful experiences and calling for reform. Both perspectives are real, and families should be informed about both before choosing an ABA provider. Look for modern, relationship-first practitioners who center the child's dignity and consent.
Similarly, "recovery" / "cure" language and biomedical or detox approaches are contested: this site presents them as contested, not as settled fact. The goal for a family — per the autistic self-advocate framing this site follows — is functional and happy, not "normal".
Not medical advice. Classifications are a parent summary of published materials; therapy decisions belong with your child's clinical team.
