摘要

背景:人口调查应答率低的问题已经存在了几十年,但很少有研究探索如何在随访人群队列研究中提高应答率。方法:从澳大利亚的一个大型人群队列——45岁及以上研究中抽取了10万名成年人作为样本,在基线队列建立后进行了3.5年的随访。在邮寄5000份调查问卷的试点中,回复率仅为41.7%。本研究测试了提高回复率的方法,分为三组,每组1000人(1)收到预先通知明信片,然后收到问卷,(2)收到问卷,然后收到后续提醒信,(3)这两种策略。结果:与试点相比,增强的策略都产生了改善的反应率,结果平均反应率为53.7%。当同时使用明信片和问卷提醒时,应答率最高(56.4%),但仅与单独使用明信片(50.5%)相比,应答率明显更高,而单独使用提醒(54.1%)则没有。在剩余的92,000名参与者中使用了联合方法进行招募,结果进一步提高了61.6%的响应率。结论:在大规模流行病学调查中,单独或联合应用明信片和提示随访问卷的调查提示可提高随访率。

Maximising follow-up participation rates in a large scale 45 and Up Study in Australia.

Background: The issue of poor response rates to population surveys has existed for some decades, but few studies have explored methods to improve the response rate in follow-up population cohort studies.

Methods: A sample of 100,000 adults from the 45 and Up Study, a large population cohort in Australia, were followed up 3.5 years after the baseline cohort was assembled. A pilot mail-out of 5000 surveys produced a response rate of only 41.7 %. This study tested methods of enhancing response rate, with three groups of 1000 each allocated to (1) receiving an advance notice postcard followed by a questionnaire, (2) receiving a questionnaire and then follow-up reminder letter, and (3) both these strategies.

Results: The enhanced strategies all produced an improved response rate compared to the pilot, with a resulting mean response rate of 53.7 %. Highest response was found when both the postcard and questionnaire reminder were used (56.4 %) but this was only significantly higher when compared to postcard alone (50.5 %) but not reminder alone (54.1 %). The combined approach was used for recruitment among the remaining 92,000 participants, with a resultant further increased response rate of 61.6 %.

Conclusions: Survey prompting with a postcard and a reminder follow-up questionnaire, applied separately or combined can enhance follow-up rates in large scale survey-based epidemiological studies.

期刊介绍: Emerging Themes in Epidemiology is an open access, peer-reviewed, online journal that aims to promote debate and discussion on practical and theoretical aspects of epidemiology. Combining statistical approaches with an understanding of the biology of disease, epidemiologists seek to elucidate the social, environmental and host factors related to adverse health outcomes. Although research findings from epidemiologic studies abound in traditional public health journals, little publication space is devoted to discussion of the practical and theoretical concepts that underpin them. Because of its immediate impact on public health, an openly accessible forum is needed in the field of epidemiology to foster such discussion.
