Standard Pediatric Crohn's Disease App This App includes five NIH PROMIS symptom scales—a publicly available set of valid and reliable PROs .
Each of these five scales (except Anxiety Scale) were significantly associated with Crohn's disease activity in a linear and clinically meaningful manner in a study including 276 children age 9-17 (Arvanitis et al 2016).
Thus, this App can be used as a starting point for building an App that measures PROs in children with Crohn's Disease.
