Increasing response rates in community health surveys administered by telephone.
This paper reports the effects of two methods used to increase response rates in a community health survey administered by telephone. Converting refusals resulted in an increase of 3.7% in the final response rate, while the investigation and identification of indeterminate telephone numbers increased the response rate by an additional 6.1%. Together, these methods resulted in an increase of 9.8%, from an initial response rate of 70.1% to a final lower-bound response rate of 79.9%. The use of these methods helped to reduce non-response bias at a minimal cost.
