Each year the program strives to reach different audiences with targeted anti-abuse messages, and in 2000, the campaign focused on the issue of teen dating violence. The interviews took place from December 4 to 14, 2000. Knowledge Networks employs a complex sample stratification design that incorporates the known probabilities of selection associated with geographical location, the number of phone lines, and whether or not the phone number is listed. Once a Knowledge Networks household is selected, members are contacted first by an express delivery mailing and then by telephone for enrollment in the panel. Every participating Knowledge Networks household receives free hardware, free Internet access, free email accounts, and ongoing technical support.
Participants receive a short multimedia survey about once a week.
Surveys are delivered by email on the same standardized hardware, through their television sets.
