To maximise the response rate in a community survey among ethnic minorities by combining postal questionnaires and interviews and to evaluate the validity of combining results from these different methods.
A cross-sectional community survey of a local population using postal questionnaires with interview questionnaires for non-respondents. Postal questionnaires were in English and interview questionnaires were prepared in South Asian languages. A sub-sample completed both postal and interview questionnaires.
Two general practices in Tameside, Greater Manchester, UK.
Questionnaires were mailed to 1,267 people. People were included if they defined their ethnicity as Indian, Pakistani, Bangladeshi or a combination of these. Fifty-five people who returned postal questionnaires were also interviewed.
Overall response rate was 75%. Comparison of questionnaire and interview responses produced values of kappa ranging from marginally below zero to one. Equivalence was greater with a shorter time between postal completion and interview and where questions were more objective.
It is possible to achieve a good response rate for an epidemiological study among ethnic minorities by using both postal questionnaires and interviews. Care should be taken when results from these two methods are combined, since equivalence is uncertain.
通过结合邮寄问卷调查和访谈，使少数民族社区调查的回应率最大化，并评估将这两种不同方法的结果相结合的有效性。
对当地人群进行横断面社区调查，对未回复者采用邮寄问卷与访谈问卷相结合的方式。邮寄问卷用英文，访谈问卷用南亚语言编写。一个子样本同时完成了邮寄问卷和访谈问卷。
英国大曼彻斯特郡塔姆赛德的两家全科诊所。
向1267人邮寄了问卷。如果人们将自己的种族定义为印度人、巴基斯坦人、孟加拉人或这些种族的组合，则被纳入调查。对55名回复邮寄问卷的人也进行了访谈。
总体回应率为75%。问卷和访谈回复的比较得出的卡帕值范围从略低于零到一。在邮寄问卷完成和访谈之间的时间较短以及问题更客观的情况下，等效性更高。
通过使用邮寄问卷和访谈，有可能在少数民族的流行病学研究中获得良好的回应率。由于两种方法结果的等效性不确定，在将这两种方法的结果结合时应谨慎。
