To establish unified definitions and descriptions for core behavioral features in Prader-Willi syndrome to facilitate standard outcome measurement in future clinical trials.
Convened the International Prader-Willi Syndrome Clinical Trials Consortium Behavior Outcomes Working Group, bringing together expert scientists, clinicians, and patient advocacy representatives.
Evaluated established assessment tools and emerging instruments designed to quantify complex behavioral symptoms in clinical settings.
Established clinical consensus definitions for prominent behavioral phenotypes, specifically severe hyperphagia, temper outbursts, anxiety, obsessive-compulsive behaviors, rigidity, and social cognition deficits.
Characterized the clinical interconnectedness and everyday quality-of-life impacts of these behaviors using representative patient vignettes.
Identified existing gaps in behavioral assessment instruments required for valid, sensitive clinical trial outcome measures.
