The authors' previous research has shown that in cross-sectional analysis, partner-specific perceptions of risk for gonorrhea and chlamydial and HIV infection correlated with partner-specific intentions to use condoms.
The goal was to determine whether partner-specific measures of perception of risk for STDs (PRSTD) predict partner-specific condom use 6 months later among high-risk and low-risk youth.
Youths aged 14 to 19 years were recruited from an STD clinic (n = 236) and an HMO teen clinic (n = 306) and were interviewed at baseline and at 6 months about PRSTD, attitudes about condoms, self-efficacy, normative expectations, and condom use.
PRSTD with a main sex partner was an independent predictor of condom use with a main sex partner in the STD clinic cohort (odds ratio = 2.5; 95% CI = 1.1-6.2). There was no association between PRSTD with a casual sex partner and condom use in this cohort or between PRSTD for main or casual sex partners and condom use in the HMO teen clinic cohort.
Interventions that target high-risk adolescents should focus on PRSTD with a main sex partner.
作者之前的研究表明，在横断面分析中，对淋病、衣原体感染和艾滋病毒感染的特定伴侣风险认知与特定伴侣使用避孕套的意图相关。
目的是确定性传播疾病（STD）风险认知的特定伴侣测量指标（PRSTD）是否能预测高危和低危青少年6个月后特定伴侣的避孕套使用情况。
从一家性病诊所（n = 236）和一家健康维护组织（HMO）青少年诊所（n = 306）招募了14至19岁的青少年，并在基线和6个月时就PRSTD、对避孕套的态度、自我效能、规范期望和避孕套使用情况进行访谈。
在性病诊所队列中，与主要性伴侣的PRSTD是与主要性伴侣使用避孕套的独立预测因素（优势比 = 2.5；95%置信区间 = 1.1 - 6.2）。在该队列中，与临时性伴侣的PRSTD和避孕套使用之间没有关联，在HMO青少年诊所队列中，主要或临时性伴侣的PRSTD与避孕套使用之间也没有关联。
针对高危青少年的干预措施应侧重于与主要性伴侣的PRSTD。
