The purpose of this study was to develop and test a sexual-partner-related risk behavior index to identify high-risk individuals most likely to have a sexually transmitted infection (STI). Patients from five STI and adolescent medical clinics in three US cities were recruited (N = 928; M age = 29.2 years). Data were collected using audio-computer-assisted self-interviewing. Of seven sexual-partner-related variables, those that were significantly associated with the outcomes were combined into a partner-related risk behavior index. The dependent variables were laboratory-confirmed infection with Chlamydia trachomatis, Neisseria gonorrhoeae, and/or Trichomonas vaginalis. Nearly one-fifth of the sample (169/928; 18.4%) tested positive for an STI. Three of the seven items were significantly associated with having one or more STIs: sex with a newly released prisoner, sex with a person known or suspected of having an STI, and sexual concurrency. In combined form, this three-item index was significantly associated with STI prevalence (p < .001). In the presence of three covariates (gender, race, and age), those classified as being at-risk by the index were 1.8 times more likely than those not classified as such to test positive for an STI (p < .001). Among individuals at risk for STIs, a three-item index predicted testing positive for one or more of three STIs. This index could be used to prioritize and guide intensified clinic-based counseling for high-risk patients of STI and other clinics.
本研究的目的是开发并测试一个与性伴侣相关的风险行为指数，以识别最有可能感染性传播感染（STI）的高危个体。招募了来自美国三个城市的五家性传播感染及青少年医疗诊所的患者（N = 928；平均年龄 = 29.2岁）。数据通过音频计算机辅助自我访谈收集。在七个与性伴侣相关的变量中，那些与结果显著相关的变量被合并为一个与伴侣相关的风险行为指数。因变量为经实验室确诊的沙眼衣原体、淋病奈瑟菌和/或阴道毛滴虫感染。近五分之一的样本（169/928；18.4%）性传播感染检测呈阳性。七个项目中的三个与感染一种或多种性传播感染显著相关：与新获释囚犯发生性行为、与已知或疑似感染性传播感染的人发生性行为以及同时与多名性伴侣发生性行为。以组合形式，这个三项指数与性传播感染患病率显著相关（p < .001）。在存在三个协变量（性别、种族和年龄）的情况下，被该指数归类为高危的个体感染性传播感染检测呈阳性的可能性比未被归类为高危的个体高1.8倍（p < .001）。在有性传播感染风险的个体中，一个三项指数可预测三种性传播感染中一种或多种检测呈阳性。该指数可用于对性传播感染高危患者及其他诊所进行基于诊所的强化咨询进行优先排序和指导。
