2007 and 2008 National Survey of Latinos: These are the first studies of their kind to interview Hispanics nationally using a dual-frame design. Each study interviewed at least 750 Hispanics via cell phones and 1,000 via landlines. The studies included dual users within both frames and explored optimal weighting strategies for dual-frame designs. Conducted for Pew Hispanic Center.

NOLA II: Having conducted the first major NOLA study in 2006, SSRS repeated the study in 2008. This time, however, we employed a hybrid design that utilized mail, internet, door-to-door, and telephone methodologies. SSRS developed an address-based frame and overlaid listed telephone information on the sample. Those with a listed number were directed to a traditional telephone survey, while unlisted numbers were sent invitations in which they were given the choice to complete the survey online or call an 800 number to complete the survey by telephone. To boost non-response and ensure adequate coverage of still-devastated areas, SSRS conducted over 400 door-to-door in-person interviews. The study is being heralded as a case study in design excellence in sampling a frame that has undergone tremendous change since Hurricane Katrina. Conducted for the Henry J. Kaiser Family Foundation, September-November 2006 and March-April 2008. For reports and data see http://www.kff.org/kaiserpolls/7659.cfm

Commonwealth Young Adults: This young adults study employed a dual frame design that was stratified to maximize low income and ethnic minorities. It is one of the first dual frame designs of young Americans to be conducted in the United States.

MA Health Insurance Survey: Massachusetts recently passed a universal healthcare bill. This ongoing study tracks the progress of movement toward universal coverage for Massachusetts residents and, at the same time, explores the nature and quality of this coverage. In 2008, the study used a hybrid design with both a landline telephone frame and an address-based frame in which listed-sample residents were called to complete the study while unlisted respondents were sent invitations to participate via a call-in 800 number or online. Conducted for The Massachusetts Division of Health Care Finance and Policy (DHCFP) and the Urban Institute, June 26 to August 25, 2008
