Anne Wheeler, PhD RTI International Development and Validation of an Angelman Specific Behavior Measure
Individuals with Angelman syndrome (AS) are known to have an increased likelihood of exhibiting challenging behavior, especially in situations that are anxiety provoking. These behaviors substantially affect family functioning and caregiver mental health. However, there is not a well-established and validated measurement that helps capture the frequency, nature, and severity of challenging behavior in people with intellectual disability, much less in conditions like AS, where communication challenges are a significant problem.
The FDA developed a series of four methodological patient-focused drug development (PFDD) guidance documents which highlights the importance of using patient input to identify endpoints that are important and valid. As several potential future therapies for AS are being developed, an assessment that appropriately and objectively measures behavioral symptoms is needed.
