Sensory integration therapy for children with autism and sensory processing difficulties: the SenITA RCT

Area of Science:

• Pediatric Occupational Therapy
• Autism Spectrum Disorder Research
• Sensory Processing Interventions

Background:

• Carers report unmet needs for occupational therapy services for autism-related sensory difficulties.
• Limited evidence exists to support specific therapeutic approaches for these challenges.

Purpose of the Study:

• To determine the clinical effectiveness of sensory integration therapy (SIT) for children with autism and sensory difficulties.
• To assess the cost-effectiveness of SIT across behavioral, functional, and quality-of-life outcomes.

Main Methods:

• A parallel-group randomized controlled trial was conducted with 138 participants.
• The intervention involved manualized SIT over 26 weeks, compared to usual care.
• Primary outcome was problem behaviors (Aberrant Behavior Checklist); secondary outcomes included adaptive behavior, stress, and quality of life.

Main Results:

• No significant main effects of SIT were observed on primary outcomes at 6 or 12 months.
• Some subgroup differences were noted for irritability/agitation, carer stress, and goal performance.
• Health economic evaluation indicated SIT is not cost-effective compared to usual care.

Conclusions:

• Sensory integration therapy did not demonstrate clinical benefit above standard care for children with autism.
• Further investigation into specific subgroup effects is warranted.
• The therapy may be effective for individualized performance goals, but maintenance and additionality to standard care remain unclear.
