We studied women 45-54 years of age from two communities who failed to return a mailed survey in an experiment to assess the impact on interviewing response rates of leaving messages on telephone answering machines at the time of telephone follow-up. There were 88 and 103 subjects assigned to the "message" and "no message" groups, respectively. After adjustment for age, interviewer, and community, leaving messages increased the rate of reaching a household by about 15% and improved the overall interviewing response rate by about 15% as well. This improvement was more apparent in women from the higher socioeconomic status community.
我们研究了来自两个社区的45至54岁女性，这些女性在一项评估电话随访时在电话答录机上留言对访谈回复率影响的实验中未回复邮寄的调查问卷。分别有88名和103名受试者被分配到“留言”组和“无留言”组。在对年龄、访谈员和社区进行调整后，留言使联系到家庭的比率提高了约15%，总体访谈回复率也提高了约15%。这种改善在社会经济地位较高社区的女性中更为明显。
