To examine the quality of response rate reporting and to identify methodological factors influencing response rates in published patient satisfaction studies.
Examination and analysis of 210 studies from 200 papers published in 1994 in 141 different health journals. Papers were located in the following databases: British Nursing Index, CINAHL, EMBASE, MedLine, Popline, and PsycLIT.
Reported and calculated response rates, collection and recruitment procedures of published studies, and type of instruments used for data collection.
Forty-eight per cent of studies reported a response rate. The mean response rate was 72.1%. There was no association between response rate and the type of instrument used for data collection. Studies which used a face-to-face approach to either subject recruitment (mean response rate, 76.7%) or data collection (mean response rate, 76.9%) were associated with significantly higher response rates than those in which subjects were recruited by mail (mean response rate, 66.5%) or data were collected by mail (mean response rate, 67%). Response rate was not related to questionnaire length.
Patient satisfaction studies generally show poor awareness of the importance of methodological issues relevant to response rate. Far more attention to this aspect is needed if findings in this field are to be accepted as valid and useful.
检验患者满意度研究中应答率报告的质量，并确定影响已发表研究中应答率的方法学因素。
对1994年发表在141种不同健康期刊上的200篇论文中的210项研究进行审查和分析。这些论文来自以下数据库：《英国护理索引》、护理学与健康领域数据库、《荷兰医学文摘》、《医学索引》、人口信息在线数据库和心理学文摘数据库。
报告的和计算得出的应答率、已发表研究的收集和招募程序，以及用于数据收集的工具类型。
48%的研究报告了应答率。平均应答率为72.1%。应答率与用于数据收集的工具类型之间没有关联。采用面对面方式进行受试者招募（平均应答率为76.7%）或数据收集（平均应答率为76.9%）的研究，其应答率显著高于通过邮件招募受试者（平均应答率为66.5%）或通过邮件收集数据（平均应答率为67%）的研究。应答率与问卷长度无关。
患者满意度研究总体上对与应答率相关的方法学问题的重要性认识不足。如果该领域的研究结果要被视为有效且有用，就需要更加关注这一方面。
