About

A common feature of ASD is over or under sensitivity to the environment and difficulty putting sensory information together in an orderly way, referred to here as sensory issues. Building on previous work, this study will test the efficacy of Sensory Integration Therapy (SIT), a non-invasive intervention to improve functional skills in children with ASD, in comparison to commonly applied ABA behavioral treatments, in the treatment of ASD symptoms. A total of 180 children with ASD and sensory issues in the greater New York City Metropolitan area will complete this study.

Full description

Autism Spectrum Disorders (ASD) are among the most common neurodevelopmental disorder with estimated costs of treatment across the lifespan of $3.2 million. A common feature of ASD is over or under sensitivity to the environment and difficulty putting sensory information together in an orderly way, referred to here as sensory issues. Such sensory issues are now included in the diagnostic criteria in the DSM5 under the Restrictive and Repetitive Behaviors and Interests Criteria. These sensory issues have a deleterious effect on functional skills and limit participation in work, education, and social activities for individuals with ASD and their family. Building on previous work, this study seeks to extend understanding of Sensory Integration Therapy (SIT) as a non-invasive intervention to improve functional skills in children with ASD and sensory issues, and to test its efficacy in comparison to commonly used applied behavioral treatments. Further, the investigators will explore the proposed neurobiological mechanisms by which this intervention may work, and phenotypic moderators of outcome. This study utilizes a randomized trial to compare SIT to a commonly used behavioral intervention to evaluate outcomes on functional skills as a basis for improved independence over the lifetime. A total of 180 children with ASD and sensory issues in the greater New York City Metropolitan area will complete this study.

Enrollment: 135 patients

Sex: All

Ages: 6 years to 114 months old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Between the ages of 6.0 and 9.5 at the time of enrollment
2. Have a diagnosis of ASD that is confirmed by our research certified licensed psychologist based on clinical impression, DSM-5 criteria, and cut off scores from the Autism Diagnostic Schedule -2 (ADOS) (or CARS; an adjustment made as a consequence of pandemic) and the Autism Diagnostic Interview - Revised (ADI-R)
3. Has a non-verbal cognitive level of 70 or above (IQ cutoff is based on feasibility study data, and we make exceptions on a case-by-case basis to as low as 65)
4. Demonstrate difficulty processing and integrating sensory information as measured by the Sensory Profile (SP; 3 or more subscales or total test score in the definite difference range; or the Sensory Integration and Praxis Test -SIPT-; score of -1.0 on 3 or more subtests)
5. Guardians willing to attend 3 weekly sessions for the duration of the period and to refrain from initiation of any new behavioral, therapeutic or alternative treatments during the study period
6. If on psychotropic medication, they are at a point where dosage and treatment are stabilized for the duration of the study.

Exclusion criteria

• Children who are receiving > 12 hours/week of ongoing ASD-related services(excluding their educational programing), or who are receiving more than one hour per week of services that closely approximate the experimental intervention, will be excluded. Additionally, for safety reasons, children with significant medical co-morbidities (e.g., major heart problems, blindness, deafness, cerebral palsy, Fragile X or Down Syndrome, or tuberous sclerosis) will not be allowed to participate.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

135 participants in 3 patient groups

Sensory Integration Therapy

Experimental group

Description:

Children receive manualized SIT intervention that follows principles of sensory integration. SIT directly addresses the specific sensory factors hypothesized to underlie the child's functional skills difficulties and follows the Data Driven Decision Making Process, to tailor the intervention to the child's specific sensory issues.

Treatment:

Behavioral: Sensory Integration Therapy

Applied Behavioral Analysis

Active Comparator group

Description:

This involves examination of environmental variables that influence behavior and altering those variables to improve the child's skills. Intervention is individualized based on identified needs of the child, assessment of environmental variables impacting their performance of specific functional skills, and their abilities.

Treatment:

Behavioral: Applied Behavioral Analysis

No Treatment

No Intervention group

Description:

Treatment as usual will occur through the treatment period. As with the other treatment conditions, the participant agrees to refrain from beginning new treatments during participation in this study.
