目的：确定风险行为评估 (RBA) 梅毒问题的重测信度、敏感性和特异性以及标准相关有效性。 RBA 是一种标准化工具，已用于吸毒者 STD 的多项研究。方法：在重测可靠性研究中，219 名注射吸毒者在 48 小时内完成了两次 RBA。为了确定标准相关有效性，对同时完成 RBA 的 207 名个体进行了快速血浆反应素试验 (RPR)，并对 206 名个体进行了梅毒螺旋体颗粒凝集试验 (TP-PA) 进行了测试。结果：“医生或护士告诉您多少次您患有梅毒？”问题的重测信度？为 0.78。 “您最后一次接受梅毒治疗是在哪一年？”这一问题的重测信度。为 0.89。对于自我报告与R-PR检验的比较，自我报告的敏感性为46.2%，特异性为95.7%。将自我报告与TP-PA测试进行比较，自我报告的敏感性为37%，特异性为97.7%。结论：自我报告梅毒感染史具有良好的可靠性、优异的特异性和中等敏感性。在使用这些自我报告项目的任何研究中都需要考虑这些特征。
Objective: To determine the test-retest reliability, sensitivity and specificity, and criterion-related validity of the Risk Behavior Assessment (RBA) syphilis questions. The RBA is a standardized instrument that has been used in several studies of STDs in drug users.Methods: For the test-retest reliability study, 219 injection drug users completed the RBA twice within a 48-hour period. To determine criterion-related validity, 207 individuals, who also completed the RBA, were tested with the rapid plasma reagin test (RPR), and 206 individuals were also tested with the Serodia Treponema pallidum particle agglutination test (TP-PA).Results: The test-retest reliability for the question "How many times have you been told by a doctor or a nurse that you had syphilis?" was 0.78. The test-retest reliability for the question "In what year were you last treated for syphilis?" was 0.89. For the comparison of self-report with the R-PR test, the sensitivity of self-report was 46.2% and the specificity was 95.7%. For the comparison of self-report with the TP-PA test, the sensitivity of self-report was 37% and the specificity was 97.7%.Conclusions: Self-reports of syphilis infection history were found to have good reliability, excellent specificity, and moderate sensitivity. These characteristics need to be taken into account in any study using these self-report items.
