متن کاملIncentives in Random Digit Dial Telephone Surveys: A Replication and Extension
Singer, Van Hoewyk, and Maher (2000) found that a $5 prepaid incentive markedly increased response rates during the period 1996 to 1998 on the University of Michigan’s monthly RDD Survey of Consumer Attitudes (SCA). Although this led the study to adopt that incentive, SCA’s response rate has declined sharply since then. We examine (a) whether the effect on response rates of the $5 prepaid incen...
متن کاملComplementing random-digit-dial telephone surveys with other approaches to collecting sensitive data.
Surveys of sensitive topics, such as the Injury Control and Risk Surveys (ICARIS) or the Behavioral Risk Factors Surveillance System (BRFSS), are often conducted by telephone using random-digit-dial (RDD) sampling methods. Although this method of data collection is relatively quick and inexpensive, it suffers from growing coverage problems and falling response rates. In this paper, several alte...

Knowledge of the characteristics of survey non-respondents is important to determine generalizability to the population of interest. In a recent random-digit dialling survey of health behaviours only 73 per cent of the households contacted provided any information about household composition, and only 74 per cent of those actually completed the extended interview, for an overall response rate o...
