Description: This webinar will address the concept of dosage- the amount of intervention needed to make a meaningful change- in relation to Ayres Sensory Integration (ASI). A synthesis of dosages and resulting outcomes recorded in the ASI literature will be discussed. Dosages and efficacy of alternative evidence-based interventions will also be explored to guide a discussion on the available evidence on dosage, factors that impact the current delivery of ASI intervention as well as factors for occupational therapists to consider when making dosage decisions.

Learning Objectives:
By the end of this webinar viewers will be able to:

  1. Discuss the current evidence that is available on dosage within the ASI literature.
  2. Describe factors that impact current delivery model(s) of ASI intervention.
  3. Describe how specific client factors may impact the dosage decision making process for ASI
