项目计数技术是一种间接询问技术，用于估计从事污名化行为的人的比例。这种技术被期望产生比普通的直接询问技术更合适的估计，因为它要求应答者根据几个项目的列表，简单地指出适用于他们的项目的数量，包括目标关键项目。通过一项实验网络调查，对直接提问法和项目计数法进行了比较。与直接询问法相比，物品计数法对商店扒手比例的估计高出了近10个百分点，而在无害献血方面，使用这两种方法的估计之间的差异几乎不显著。调查结果表明，在项目计数技术中，与直接提问相比，被调查者倾向于报告较少的总行为。这种趋势在较长的项目列表中更为明显。对项目计数技术的三种域估计方法进行了比较，结果表明交叉估计方法是最合适的方法。在女性受访者、中年受访者、居住在城市地区的受访者和受过高等教育的受访者中，在物品数量和直接提问技术之间的领域估计存在很大差异。
The item count technique is an indirect questioning technique that is used to estimate the proportion of people who have engaged in stigmatizing behavior. This technique is expected to yield a more appropriate estimate than the ordinary direct questioning technique because it requests respondents to indicate, based on a list of several items, simply the number of items that are applicable to them, including the target key item. An experimental web survey was conducted in an attempt to compare the direct questioning technique and the item count technique. Compared with the direct questioning technique, the item count technique yielded higher estimates of the proportion of shoplifters by nearly 10 percentage points, whereas the difference between the estimates using these two techniques was mostly insignificant with respect to innocuous blood donation. The survey results suggest that in the item count technique respondents tend to report fewer total behaviors compared to the direct question case. This tendency is more pronounced in the case of longer item lists. Three domain estimators for the item count technique were compared, and the cross-based method appeared to be the most appropriate method. Large differences in domain estimates for shoplifting between the item count and direct questioning techniques were found among female respondents, middle-aged respondents, respondents living in urban areas, and highly-educated respondents.
