Opioid-dependent (OD) women tend to engage in unprotected sex with high-risk partners, placing themselves at elevated risk for sexually transmitted HIV infection. This behavior generally persists after completion of interventions that increase sexual HIV risk reduction knowledge and skills, suggesting that decision-making biases may influence HIV transmission among OD women.
The primary aim of this report is to examine delay discounting of condom-protected sex among OD women and non-drug-using control women using the novel Sexual Discounting Task (SDT; Johnson and Bruner, 2012). Data were collected from 27 OD women and 33 non-drug-using control women using the SDT, a monetary discounting task, and the Barratt impulsiveness scale (BIS-11).
OD women discounted the value of delayed condom-protected sex more steeply than controls for hypothetical sexual partners in the two sets of paired partner conditions examined. Overall, women discounted condom protected sex more steeply for partners they perceived as being lowest STI risk vs. those they perceived as being highest risk. Steeper discounting of condom-protected sex was significantly associated with higher scores on the BIS-11, but not with discounting of money.
Delay discounting of condom-protected sex differs between OD women and non-drug-using women, is sensitive to perceived partner risk, and is correlated with a self-report measure of impulsivity, the BIS-11. The effect of delay on sexual decision-making is a critical but underappreciated dimension of HIV risk among women, and the SDT appears to be a promising measure of this domain. Further investigation of these relationships is warranted.
阿片类药物依赖（OD）女性往往与高危伴侣进行无保护性行为，使自己面临感染性传播艾滋病毒的更高风险。在完成增加降低性传播艾滋病毒风险知识和技能的干预措施后，这种行为通常仍会持续，这表明决策偏差可能会影响OD女性中的艾滋病毒传播。
本报告的主要目的是使用新颖的性折扣任务（SDT；Johnson和Bruner，2012年），研究OD女性和非吸毒对照女性对使用避孕套性行为的延迟折扣情况。使用SDT、货币折扣任务和巴拉特冲动性量表（BIS-11）从27名OD女性和33名非吸毒对照女性中收集数据。
在两组配对伴侣条件下，对于假设的性伴侣，OD女性比对照组更陡峭地折扣延迟使用避孕套性行为的价值。总体而言，女性对她们认为性传播感染风险最低的伴侣比对她们认为风险最高的伴侣更陡峭地折扣使用避孕套的性行为。对使用避孕套性行为更陡峭的折扣与BIS-11得分较高显著相关，但与货币折扣无关。
OD女性和非吸毒女性对使用避孕套性行为的延迟折扣存在差异，对感知到的伴侣风险敏感，并且与冲动性的自我报告测量指标BIS-11相关。延迟对性决策的影响是女性艾滋病毒风险中一个关键但未得到充分重视的维度，而SDT似乎是该领域一个有前景的测量指标。有必要对这些关系进行进一步研究。
