The purpose of this paper is to assess the internal consistency of self-reported condom use among sex workers in Puerto Plata and Santo Domingo, Dominican Republic. We examined the responses to questions about condom use among 4 cross-sectional samples of sex workers. We compared measures based on: (1) questions using always-to-never scales; (2) questions about use with the past 5 clients; and (3) questions about use in the past week obtained from a retrospective coital log. In each sample, more women reported 'always' using condoms with clients than with each of the past 5 clients. In 3 of the 4 samples, only about half of the women who reported 'always' using condoms used condoms with the most recent 5 clients and with all clients in the past week. Internal consistency was significantly higher when the comparison was limited to use with the most recent 5 clients and use in the past week. Self-reported measures of condom use can be difficult to interpret. Assessing the internal consistency of several measures of use provides insight into the strengths and weaknesses of each measure.
本文旨在评估多米尼加共和国普拉塔港和圣多明各性工作者自我报告的避孕套使用情况的内部一致性。我们检查了4个性工作者横断面样本中关于避孕套使用问题的回答。我们基于以下内容比较了各项测量指标：（1）使用从总是到从不量表的问题；（2）关于与过去5名客户使用情况的问题；（3）从回顾性性交记录中获取的关于过去一周使用情况的问题。在每个样本中，报告“总是”与客户使用避孕套的女性多于报告与过去5名客户中的每一位都使用避孕套的女性。在4个样本中的3个样本中，报告“总是”使用避孕套的女性中，只有约一半的人与最近5名客户以及过去一周内的所有客户都使用了避孕套。当比较仅限于与最近5名客户的使用情况和过去一周的使用情况时，内部一致性显著更高。自我报告的避孕套使用测量指标可能难以解释。评估几种使用情况测量指标的内部一致性有助于深入了解每种指标的优缺点。
