STUDY OBJECTIVE
The purpose was to determine whether asking about ethnic origin and housing tenure in a postal survey affects the response rate.
DESIGN
The study derived from a postal survey designed to determine eligibility for a study of outpatients. A two way factorial design was used to look at the two experimental factors, questionnaires being randomly divided into four groups with or without questions about ethnic origin and housing tenure.
PARTICIPANTS
10,000 people (1000 from each of 10 areas) were systematically sampled from electoral registers, the areas being chosen to give a nationally representative sample.
MAIN RESULTS
The response rate was 66% irrespective of whether ethnic origin was asked about, but was 65% and 67% respectively to questionnaires with and without questions about housing tenure.
CONCLUSIONS
Asking about ethnic origin did not affect the overall response to this survey although it is possible that the response from some ethnic minority groups was lower. Asking about housing tenure slightly, but significantly, decreased response.
研究目的
目的是确定在邮政调查中询问种族起源和住房保有情况是否会影响回复率。
设计
该研究源自一项旨在确定门诊患者研究资格的邮政调查。采用两因素析因设计来研究两个实验因素，问卷被随机分为四组，分别有无关于种族起源和住房保有情况的问题。
参与者
从选民登记册中系统抽取10000人（来自10个地区，每个地区1000人），所选地区构成全国代表性样本。
主要结果
无论是否询问种族起源，回复率均为66%，但对于有和没有住房保有情况问题的问卷，回复率分别为65%和67%。
结论
询问种族起源虽可能使一些少数族裔群体的回复率较低，但并未影响本次调查的总体回复率。询问住房保有情况会轻微但显著降低回复率。
