To determine the feasibility of using audio computer-assisted self-interviewing (ACASI) for data collection in developing countries, and to compare responses to questions eliciting sensitive information about sexual behavior using ACASI versus computer-assisted personal interviewing (CAPI) in five developing countries.
A feasibility study determined whether ACASI could be used in populations in developing countries. A follow-up, randomized crossover study compared responses to questions eliciting sensitive information about sexual behavior using ACASI versus CAPI.
The NIMH Collaborative HIV/STD Prevention Trial conducted a feasibility study of ACASI in convenience samples in China, India, Peru, and Russia, then a randomized crossover ACASI versus CAPI study among volunteers in these countries plus Zimbabwe.
Approximately equal numbers of men and women completed the feasibility study; the results suggested a high comfort level among participants. Married respondents in China and India appeared to give unreliable responses on sexual activity. In the crossover study, the pattern of responses to sensitive questions showed few differences. In China, higher rates of sexual risk were reported on CAPI. In Peru and Russia, differences by mode were found in the number of partners in the past year.
Despite variable computer experience and literacy, feasibility study participants reported ease in completing ACASI, and preferred a computer to an interviewer for answering sensitive questions, or had no preference. In the crossover study, most participants gave similar responses on both modes of survey administration. ACASI appears to be feasible in these settings, although low literacy may pose problems if participants cannot clarify questions.
确定在发展中国家使用音频计算机辅助自我访谈(ACASI)进行数据收集的可行性,并比较在五个发展中国家使用ACASI与计算机辅助个人访谈(CAPI)来获取有关性行为敏感信息问题的回答情况。
一项可行性研究确定ACASI是否可用于发展中国家的人群。一项后续的随机交叉研究比较了使用ACASI与CAPI获取有关性行为敏感信息问题的回答情况。
美国国立精神卫生研究所(NIMH)的协作性艾滋病毒/性传播疾病预防试验在中国、印度、秘鲁和俄罗斯的便利样本中对ACASI进行了可行性研究,然后在这些国家以及津巴布韦的志愿者中开展了ACASI与CAPI的随机交叉研究。
完成可行性研究的男性和女性人数大致相等;结果表明参与者的舒适度较高。中国和印度已婚受访者关于性活动的回答似乎不可靠。在交叉研究中,对敏感问题的回答模式差异不大。在中国,CAPI方式下报告的性风险发生率较高。在秘鲁和俄罗斯,过去一年性伴侣数量在调查方式上存在差异。
尽管计算机使用经验和读写能力各不相同,但可行性研究的参与者表示易于完成ACASI,在回答敏感问题时更喜欢使用计算机而非访谈员,或者没有偏好。在交叉研究中,大多数参与者在两种调查方式下的回答相似。在这些环境中,ACASI似乎是可行的,不过如果参与者无法澄清问题,则低读写能力可能会带来问题。
