Data from ICF International's Diseases, Injuries, and Risk Factors Study (DWICS) help quantify the global impact of specific diseases, injuries, and risk factors. The survey consisted of a series of pair-wise questions representing different sequelae of various health conditions. Respondents were asked to report which sequela they deem worse.
The DWICS study necessitated sophisticated data collection tools able to support several different data collection modes for this complex, multimode, multisite health survey. The study was conducted globally in multiple languages using Computer-assisted Personal Interviewing (CAPI), the Internet, and Computer-assisted Telephone Interviewing (CATI).
ICF programmed and hosted the Internet, CAPI, and CATI data collection tools in support of the University of Washington, which managed and deployed the in-field research team. DWICS collected more than 10,000 CAPI surveys, more than 2,800 CATI surveys, and more than 10,000 web surveys.
