PROMIS Pediatric General Population Survey

The purpose of this study was to establish age-based norms for all pediatric PROMIS measures (a total of 20 measures), and to assess the concurrent validity and relative precision of 9 newly developed pediatric PROMIS measures. The GfK Group (GfK, formerly Knowledge Networks) conducted the survey in 2014 on behalf of The Children’s Hospital of Philadelphia. The survey was conducted using sample from KnowledgePanel®, a probability-based web panel designed to be representative of the United States. Opt-in sample was also used to achieve the requisite number of completed surveys.
