The accuracy of self-report data may be marred by a range of cognitive and motivational biases, including social desirability response bias. The current study used qualitative interviews to examine self-report response biases among participants in a large randomized clinical trial in Vietnam. A sample of study participants was reinterviewed. The vast majority reported being truthful and emphasized the importance of rapport with the study staff for achieving veridical data. However, some stated that rapport may lead to under reporting of risk behaviors in order not to disappoint study staff. Other factors that appeared to influence accuracy of self-reports include fear that the information may be divulged, desire to enroll in the study, length of the survey, and memory. There are several methods that can be employed to reduce response biases, and future studies should systematically address response bias and include methods to assess whether approaches and survey items are effective in improving accuracy of self-report data.
自我报告数据的准确性可能会受到一系列认知和动机偏差的影响，包括社会期望反应偏差。本研究采用定性访谈来检验越南一项大型随机临床试验参与者中的自我报告反应偏差。对一部分研究参与者进行了再次访谈。绝大多数人报告说自己如实作答，并强调与研究人员建立融洽关系对于获取真实数据的重要性。然而，一些人表示，为了不让研究人员失望，融洽关系可能会导致对风险行为的报告不足。其他似乎影响自我报告准确性的因素包括担心信息可能会被泄露、希望参与研究、调查问卷的长度以及记忆力。有几种方法可以用来减少反应偏差，未来的研究应该系统地解决反应偏差问题，并包括评估方法和调查项目是否能有效提高自我报告数据准确性的方法。
