The only observational assessment and caregiver interview for classifying sensory reactivity

Authors: Paige M. Siper, Ph.D. & Teresa Tavassoli, Ph.D.

Age: 2-12 years;

Time: 20 minutes for interview and observation;





  • First clinician-administered observational assessment and corresponding caregiver interview for quantifying sensory symptoms
  • Directly examines sensory hyperreactivity, hyporeactivity, and seeking behaviors (i.e. unusual sensory interests) across visual, tactile, and auditory modalities
  • Keeping with gold-standard autism assessment practices, combines a clinical observation with caregiver interview
  • Not dependent on verbal ability—appropriate for use in profoundly affected populations
  • Low cost and low burden tool that can be used by clinicians across a variety of disciplines

Well-researched, evidence-based instrument accurately identifies presence of clinically significant sensory symptoms commonly observed in children with autism and related neurodevelopmental disorders

  • Useful in comprehensive ASD diagnostic process
  • Aids in treatment planning to target specific symptoms
  • Useful for the evaluation of response to interventions
  • Quantitative measure for research purposes
  • Observation and Interview together increases scope of symptom evaluation compared with one source alone
  • Multiple scoring options, including cutoff scores for each scale, along with probabilities, and ability to adjust cutoff criteria based on the purpose of the assessment (e.g., diagnostic vs. screening)

Why classify sensory reactivity?

·        Not all sensory reactivity is the same. Auditory hyporeactivity behavior and its implications is very different than tactile seeking behavior, for example. It should be treated and accommodated differently. Providing recommendations that target the specific symptoms will help the individual succeed across settings and help stakeholders intervene and provide support appropriately.

Why observation and interview?

·        Information from a trained clinician and informant who knows the individual well is the gold-standard for obtaining the most well-rounded, balanced, and thorough information. Caregivers will have knowledge of a child across multiple settings and over the child’s life. Qualified professionals will have expert knowledge and standardized assessment methods to compare a child’s behavior against others. Parents can provide information about how a behavior is different at home than at the testing session. Clinicians will be able to recognize behaviors that might have become normalized to the parents.
