The role of social desirability bias (SDB) in self-reported HIV risk behaviors continues to be problematic. This study examined whether SDB was associated with self-reported, via audio computer assisted self-interviewing, sexual risk behaviors among people who use drugs. The present study was conducted among 559 participants who reported having a recent sexual partner at their 6-month visit of a longitudinal study. Robust Poisson regression was used to model the association between SDB and five risk behaviors. Analyses were stratified by gender and partner type. Higher scores of SDB were associated with decreased reporting of selling sex and having more than one sexual partner. Higher SDB scores were associated with increased reporting of always using condoms during oral, vaginal, and anal sex. Gender-specific differences were observed. The inclusion of a measure of SDB in data collection, along with other strategies, can be used to both identify and reduce self-report biases.
社会期望偏差（SDB）在自我报告的艾滋病毒风险行为中所起的作用仍然存在问题。本研究通过音频计算机辅助自我访谈，调查了SDB是否与吸毒者自我报告的性风险行为相关。本研究在一项纵向研究6个月随访时报告有近期性伴侣的559名参与者中进行。稳健泊松回归用于模拟SDB与五种风险行为之间的关联。分析按性别和伴侣类型分层。SDB得分较高与报告卖性和有多个性伴侣的情况减少有关。SDB得分较高与报告在口交、阴道性交和肛交时始终使用避孕套的情况增加有关。观察到了性别差异。在数据收集过程中纳入SDB测量指标以及其他策略，可用于识别和减少自我报告偏差。
