目的：在对敏感问题进行调查时，社会期望导致的报告偏差是一个重要的考虑因素。该研究比较了传统的“电话访谈法”（TIM）和一种结合访谈和计算机数据采集方法（电话访谈和计算机问卷调查方法，简称TICQM）之间自我报告的敏感行为的频率和反应率。方法：在横断面研究中，共招募了580名男性和582名女性，随机分配到两种方法中的任何一种。总有效率约为51.6%。结果：虽然两种方法均具有较高的完成率和较低的项目无反应率，但TICQM受访者报告的敏感风险行为频率较高。TICQM采访的性活跃女性受访者更有可能报告说，她们的性伴侣是稳定的男朋友，而不是丈夫；与TIM组相比，他们也更有可能承认自己有过“一夜情”经历或接受过艾滋病毒抗体检测。在性活跃的男性受访者中也观察到类似的对比，TICQM组更有可能报告他们与女性性工作者或非正规性伴侣发生过性关系。观察到某些研究行为（例如艾滋病毒检测和药物滥用）与数据收集模式之间的关联强度存在性别差异。结论：数据收集方法的选择对敏感性研究的结果有显著影响；应特别注意研究的设计和结果的解释。
Objective: Reporting bias due to social desirability is an important consideration in carrying out surveys on sensitive issues. The study compared the frequency of self reported sensitive behaviours and response rates between the conventional "telephone interviewer method" (TIM) and a combined interviewer and computerised data capturing method (telephone interviewer and computerised questionnaire method, or TICQM).Methods: A total of 580 males and 582 females were recruited and randomly assigned to either of the two methods in a cross sectional study. The overall response rate was about 51.6%.Results: While the two methods both had high completion and low item non-response rates, the TICQM respondents reported higher frequencies of sensitive risk behaviours. Sexually active female respondents interviewed by the TICQM were more likely to report that their sex partners were their steady boyfriend, instead of their husband; and were also more likely to admit that they had had "one night stand" experiences or had undergone an HIV antibody test, when compared with their counterparts in the TIM group. Similar contrasts were observed for sexually active male respondents, that the TICQM group were more likely to report that they had had sexual intercourse with female sex workers or non-regular sex partners. Sex differences in the strength of association were observed between some studied behaviours (for example, HIV testing and substance abuse) and modes of data collection.Conclusion: The choice of data collection method has a significant impact on the results of sensitive studies; special attention should be given to designing the study and interpreting the results.
