To implement and evaluated a national survey of sexual behaviour using computer-assisted telephone interviewing (CATI).
A two-stage stratified national sample survey in which households were selected by random digit-dialing (RDD), with a single eligible interviewee per selected household, followed by subsample surveys of non-contacts and refusals to determine eligibility.
A 15-minute questionnaire based on the Global Programme on AIDS (GPA)/World Health Organization (WHO) protocol was administered by telephone to a nationally representative sample of 2361 respondents in the 18-54-year age group.
The overall response rate was 63%, but lower in the cities, in the 18-24 age group, and among men. Three-quarters of surveyed non-contacts, and a quarter of re-surveyed refusals, did not meet the eligibility criteria for the study. Less than 20% of refusals cited the subject matter of the survey as the reason for refusal. Item non-response (< 1%) increased with question sensitivity, and varied by respondent age, ethnicity and partnership status. Men reported twice as many adult lifetime partners as women.
The GPA/WHO protocol can be successfully adapted to administration by telephone, with adequate response rates and exceptionally low levels of item non-response. CATI is a cost-effective method for collecting national information on sexual behaviour in countries where there is a high level of telephone ownership. Used in conjunction with RDD, it can overcome problems of sample design in settings where there is no comprehensive population-sampling frame. Checks on item sensitivity and partner estimates suggest that acceptable levels of reliability can also be achieved.
采用计算机辅助电话访谈（CATI）实施并评估一项全国性行为调查。
一项两阶段分层全国抽样调查，通过随机数字拨号（RDD）选择家庭，每个选定家庭有一名符合条件的受访者，随后对未联系到的人和拒绝者进行子样本调查以确定其是否符合条件。
基于全球艾滋病规划署（GPA）/世界卫生组织（WHO）方案设计的一份15分钟问卷，通过电话对18 - 54岁年龄组的2361名具有全国代表性的受访者进行了调查。
总体回复率为63%，但在城市、18 - 24岁年龄组以及男性中的回复率较低。四分之三被调查的未联系到的人以及四分之一重新调查的拒绝者不符合该研究的资格标准。不到20%的拒绝者将调查主题作为拒绝的原因。项目未回复率（<1%）随着问题敏感性的增加而上升，并且因受访者年龄、种族和伴侣状况而异。男性报告的成年期性伴侣数量是女性的两倍。
GPA/WHO方案能够成功地改编为通过电话进行调查，具有足够的回复率且项目未回复率极低。在电话普及率较高的国家，CATI是一种收集全国性行为信息的具有成本效益的方法。与RDD结合使用时，它可以克服在没有全面人口抽样框架的情况下样本设计的问题。对项目敏感性和伴侣估计的检查表明，也能够实现可接受的可靠性水平。
