This article compares two national surveys carried out through the most commonly used procedures in Italy: CATI (computer-assisted telephone interviews) and SAQ-FI (self-answered questionnaires following interviews). Both surveys ask two identical questions concerning sensitive sexual behavior: early age at first intercourse and same-sex attraction. The SAQ-FI survey had both unit non-response and item non-response rates much lower than the CATI survey. Moreover, in the CATI survey, the groups with highest item non-response rates were also the groups with the lowest proportions of early intercourse and homosexual attraction. In addition, a differential analysis of the respondents produced diverse results for the two surveys. This is especially true of results by gender for same-sex attraction: Such behavior is more common among men (3.1%) than women (2.9%), according to the CATI survey, whereas the opposite is true of the SAQ-FI survey (6.1% of men vs. 7.7% women). In Italy at the beginning of the 21st century, CATI surveys reveal a lower level of early intercourse and same-sex attraction than SAQ-FI surveys. This article argues that the CATI survey underestimates the true level of these sensitive sexual behaviors in the Italian population.
计算机辅助电话访谈（CATI）和访谈后自填问卷（SAQ-FI）。两项调查都询问了两个关于敏感性行为的相同问题：初次性交的年龄和同性吸引。SAQ-FI调查的单位无回答率和项目无回答率均远低于CATI调查。此外，在CATI调查中，项目无回答率最高的群体也是初次性交和同性恋吸引比例最低的群体。此外，对受访者的差异分析在两项调查中产生了不同的结果。对于同性吸引按性别划分的结果尤其如此：根据CATI调查，这种行为在男性（3.1%）中比在女性（2.9%）中更常见，而SAQ-FI调查的情况则相反（男性为6.1%，女性为7.7%）。在21世纪初的意大利，CATI调查显示的初次性交和同性吸引水平低于SAQ-FI调查。本文认为，CATI调查低估了意大利人口中这些敏感性行为的真实水平。
