Harris Interactive conducted the survey in February 2008 via its Harris Poll Online (HPOL) Research Panel, a database that consists of several million people who have agreed to participate in online research projects. A total of 1,012 HPOL respondents, 258 people living with schizophrenia who were in treatment, and 256 caregivers completed the survey, which averaged about 17 minutes. Demographic weighting was used to ensure that the data reflect the national population of adult U.S. citizens. Propensity score weighting adjusted for respondents' propensity to be online. Data for the caregivers and individuals living with schizophrenia were not weighted.
