The CHIRR website will be retired in August, 2019.

CHIRr provides a resource of outcome variables and suggested measures to guide a comprehensive consumer health informatics assessment. The resource provides a reservoir of suggested outcome variables that make it easier to engage in health communication and related consumer health informatics intervention research.

CHIRr is intended to help scholars in diverse fields such as: consumer health informatics, health communication, social marketing, eHealth, mHealth, mass communication, public health, health promotion, and science communication. CHIRr strives to prompt similar measures and outcome variables within eHealth and mHealth where current disciplinary boundaries may result in the use of different measures to assess highly similar variables.

Updates of sections as well as new entries are provided when available. Sections of the website were updated in winter 2012-2013.
