With the expansion of telecommunication and online technologies for the purpose of survey administration, the issue of measurement validity has come to the fore.

T...

BACKGROUND In recent years, response rates to telephone surveys have declined. Online surveys may miss many older and poorer adults. Mailed surveys may have promise in securing higher response rates. METHODS In a pilot study, 1200 breast, prostate and colon patients, randomly selected from the Pennsylvania Cancer Registry, were sent surveys in the mail. Incentive amount ($3 vs. $5) and length...

OBJECTIVE The purpose of this study was to characterize response rates for mail surveys published in medical journals; to determine how the response rate among subjects who are typical targets of mail surveys varies; and to evaluate the contribution of several techniques used by investigators to enhance response rates. METHODS One hundred seventy-eight manuscripts published in 1991, represent...

Methods: An initial environmental scan provided a comprehensive understanding of the population characteristics needed to design the study and develop the survey questionnaire and focus group materials. Data were collected using telephone surveys with community health personnel and focus groups with community members (e.g., parents, children, and school personnel) affected by asthma to assess t...
