During 1965, 1585 questionnaires were sent to physicians in British Columbia, Manitoba and Ontario to elicit information about persons who had died and in whom a chronic non-specific respiratory disease had been recorded on the registration of death. The response rate to the first letter of enquiry was 54.1%. This was improved to 76.5% when the enquiry was sent by registered mail, and to 90.6% by a registered special appeal. The final response rate was 93.8% for British Columbia, 92.8% for Manitoba and 89.5% for Ontario. Although response varied with the time of the year, there was no evident relationship between response rate and characteristics of the physician. Physician characteristics studied were place and year of graduation and the nature of practice. Acceptable and high response rates to mailed questionnaires eliciting clinical data from physicians can be obtained if the investigator's concern is demonstrated by sending the request in successive waves to the diminishing group of non-respondents.
1965年期间，向不列颠哥伦比亚省、曼尼托巴省和安大略省的医生发送了1585份调查问卷，以获取有关已死亡人员的信息，这些人员的死亡登记中记录有慢性非特异性呼吸道疾病。对第一封询问信的回复率为54.1%。当通过挂号信发送询问时，回复率提高到76.5%，通过挂号特别呼吁则提高到90.6%。不列颠哥伦比亚省的最终回复率为93.8%，曼尼托巴省为92.8%，安大略省为89.5%。尽管回复随一年中的时间而有所不同，但回复率与医生的特征之间没有明显关系。所研究的医生特征包括毕业地点和年份以及执业性质。如果调查人员通过连续向未回复的人数逐渐减少的群体发送请求来表明关注，那么就可以从医生那里获得对邮寄调查问卷的可接受且较高的回复率，这些问卷用于获取临床数据。
