In this presentation, Anita Bundy discusses the importance of accurate assessment for effective intervention, using relatable examples to illustrate her points. She explains that the validity of tests lies in their interpretation, focusing on theoretical validity, which measures how well test findings align with underlying theories. Bundy evaluates various Sensory Integration (SI) tests, such as the Sensory Profile and EASI, highlighting potential discrepancies and emphasizing the need for tests to accurately reflect theoretical constructs. She concludes by advocating for a new, streamlined assessment tool that balances theoretical accuracy with practical clinical utility.
