Techniques to increase the response rate in follow‐up studies: Results of a pilot test

As a part of the design and implementation of a caseload weighting system, Arkansas Rehabilitation Services is adopting a revised client data system. To assess the validity of the data collected in the new system a follow-up survey for recently closed clients has been designed; and to insure the adequacy of the survey design several issues were considered. These included overall survey and questionnaire design. The process, designed to maximize useful information collected with limited resources, resulted in a telephone survey augmented by mail and personal interviews. The survey procedures and instrumentation were pilot tested for two months with 629 clients. This resulted in major modifications in questionnaire design and brought to light easily adopted procedural improvements resulting in less ambiguity, improved readibility, increased response rate and reduced response bias. Using the described survey methods the investigators observed an overall response rate of 50.8% which compares very favorably with that reported in other studies similar in nature.
