Sensory Integration Therapy for Preschool Children with Autism Spectrum Disorder and Co-Occurring Intellectual...

Area of Science:

• Pediatrics
• Neurodevelopmental Disorders
• Therapeutic Interventions

Background:

• Sensory Integration Therapy (SIT) is commonly used for children with Autism Spectrum Disorder (ASD).
• Evidence for SIT's effectiveness in ASD populations, particularly those with co-occurring intellectual disability, is limited.
• This study investigated the potential benefits of weekly SIT for this specific demographic.

Purpose of the Study:

• To explore the effectiveness of once-weekly Sensory Integration Therapy (SIT).
• To assess the impact of SIT on children aged 2-6 years with Autism Spectrum Disorder (ASD) and intellectual disability.
• To evaluate changes in adaptive behavior, sensory processing, and parental stress.

Main Methods:

• A non-blinded, single-group pre-post study design was employed.
• Participants received once-weekly SIT for 8 weeks.
• Outcome measures included Goal Attainment Scaling (GAS), Vineland Adaptive Behavior Scales (VABS-II), Short Sensory Profile (SSP), and Parenting Stress Index (PSI-SF).

Main Results:

• Ten children completed the intervention; changes in GAS and VABS-II showed high variability and uncertainty.
• No significant changes were observed in Short Sensory Profile (SSP) or Parenting Stress Index (PSI-SF) scores.
• The observed changes were not statistically significant and should be considered exploratory.

Conclusions:

• The study findings do not provide evidence supporting the effectiveness of Sensory Integration Therapy (SIT) for children with ASD and intellectual disability.
• Results are considered exploratory observations from a real-world clinical setting.
• Future research requires robust designs, including control groups, larger samples, and blinded assessments.
