Elizabeth Cox’s recent publication in Quality of Life Research advances the utility of novel PROMIS measures of family relationships among chronically ill children. In the study done in collaboration with investigators at UW and Children’s Hospital of Wisconsin, the PROMIS Family Relationships 8-item short form demonstrated reliability and validity for use among children with asthma, sickle cell disease and type 1 diabetes. Future work will examine how trends in family relationships over time are related to neighborhood deprivation and to health over time for chronically ill children.
