This paper reports methodological aspects and response rates of a survey with the main objective of describing the drug utilization profile of retirees of the Institute of National Social Security of Brazil, 60 years of age or older, in three simple random samples: Brazil (countrywide), Belo Horizonte municipality, and Rio de Janeiro municipality. This cross-sectional study employed two approaches: mail (self-report questionnaires) and home interviews (questionnaires completed by interviewers). This strategy allowed evaluation of response agreement between the mail and home interview approaches. In the national sample of 3,000 individuals, 1,025 only responded to the self-report questionnaire. Despite this the low response rate, there was reasonable resemblance between respondents and non-respondents, suggesting that this sample is representative of the target population. In Belo Horizonte and Rio de Janeiro the initial samples of 800 individuals were replicated for both approaches, mail and home interview. The response rates to the mail surveys were 46.8% and 34.4% in Belo Horizonte and Rio de Janeiro, respectively. The response rates to the home interviews were 80.3% and 70.7% in Belo Horizonte and Rio de Janeiro, respectively, after unavoidable attrition.
本文报告了一项调查的方法学方面及回复率，该调查的主要目的是描述巴西国家社会保障局60岁及以上退休人员的药物使用情况，采用了三个简单随机样本：巴西（全国范围）、贝洛奥里藏特市和里约热内卢市。这项横断面研究采用了两种方法：邮寄（自我报告问卷）和家庭访谈（由访谈员完成问卷）。这种策略允许评估邮寄和家庭访谈方法之间的回复一致性。在3000人的全国样本中，只有1025人回复了自我报告问卷。尽管回复率较低，但回复者和未回复者之间存在合理的相似性，表明该样本代表了目标人群。在贝洛奥里藏特和里约热内卢，对800人的初始样本同时采用了邮寄和家庭访谈两种方法。贝洛奥里藏特和里约热内卢邮寄调查的回复率分别为46.8%和34.4%。在不可避免的人员流失后，贝洛奥里藏特和里约热内卢家庭访谈的回复率分别为80.3%和70.7%。
