Response patterns to a postal survey using a cervical screening register as the sampling frame

The Effect of Multiple Mailings on Recruitment: The Multiethnic Cohort

“…These findings are generally similar to findings reported in the literature. Certainly, people have shown education and/or other proxies for socioeconomic level were inversely related to timing of response (9,10,13,17,18,28). The association of current smoking with late response has also been reported (9,10,15,17,29).…”

“…These strategies have included providing a pen/pencil, financial incentives, use of a culturally sensitive letter, and varying survey length (2)(3)(4)(5)(6)(7). In contrast, reports of post hoc analyses compared respondents to nonrespondents and those who responded early or later to recruitment efforts (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21), some of which make inferences about bias and the value of extensive recruitment methods. There have also been simulations to show how assumptions about nonrespondents or late respondents can potentially affect prevalence estimates for disease or exposure (22,23).…”

Acceptability and response to a postal survey using self-taken samples for HPV vaccine impact monitoring

“…Although our market research suggested that this would not have an effect, previous postal surveys have shown that this improved take-up rates 3 19. The period allowed for return of specimens was 6 weeks in total, between March and April 2009.…”

“…If women who were more sexually active were less likely to participate, then an underestimate in HPV prevalence is likely, while if women who were less sexually active were less likely to participate, then an over estimate in HPV prevalence is likely. From previous studies, we anticipated poorer responses from women living in more deprived areas and used SIMD for responders and non-responders to obtain sampling weights to attempt to correct for non-response bias 3 19. Women with a high level of health awareness or those who had heard about HPV and the vaccination programme may have been more likely to participate.…”

Concerned yet polluters: A survey on French research personnel and climate change

“…One method of analyzing non-response biases consists in examining the trend over time in the characteristics of respondents. This aspect has been analyzed in several studies (for example, [39][40][41][42]). By identifying who participated in the survey at a later stage, after several reminders, we can attempt to understand who did not respond.…”
