The Sexual Delay Discounting Task (SDDT; Johnson & Bruner, 2012) is a behavioral economic task that assesses sexual risk-taking by measuring likelihood of immediate and delayed condom use. The SDDT is ecologically valid and has been used to test effects of various substances on sexual risk-taking. However, considerable variety in implementation, analysis, and reporting of the SDDT may limit rigor and reproducibility of findings. The current review synthesized studies that used the SDDT to evaluate these possible variabilities systematically. A two-step search (citation-tracking and keyword-based search) was conducted to identify studies that met inclusion criteria (i.e., used the SDDT). Eighteen peer-reviewed articles met inclusion criteria. The SDDT has been implemented primarily in three populations: individuals who use cocaine, men who have sex with men, and college students. Comparable results across diverse populations support the SDDT's validity. A few studies administered substances before the SDDT. Evidence suggests that while cocaine and alcohol increased sexual risk-taking under some conditions, buspirone decreased preference for immediate condomless sex. There was also heterogeneity in the determination of data orderliness (i.e., outliers) and inconsistent reporting of task design and analysis. Considerable differences present in methodologic approaches could influence results. Reducing variation in the administration, analysis, and reporting of the SDDT will enhance rigor and reproducibility and maximize the task's tremendous potential.
性延迟折扣任务（SDDT；Johnson 和 Bruner，2012）是一种行为经济学任务，通过测量即时和延迟使用避孕套的可能性来评估性风险行为。SDDT 具有生态有效性，已被用于测试各种物质对性风险行为的影响。然而，在实施、分析和报告 SDDT 方面存在相当大的差异，可能会限制研究结果的严谨性和可重复性。本综述系统地综合了使用 SDDT 评估这些可能的变异性的研究。进行了两步搜索（引文追踪和基于关键字的搜索），以确定符合纳入标准（即使用 SDDT）的研究。有 18 篇同行评审文章符合纳入标准。SDDT 主要在三个群体中实施：使用可卡因的个体、男男性行为者和大学生。不同人群的可比结果支持了 SDDT 的有效性。一些研究在 SDDT 之前给予了物质。有证据表明，虽然可卡因和酒精在某些情况下会增加性风险行为，但丁螺环酮会降低对即时无保护性行为的偏好。在确定数据有序性（即异常值）和任务设计和分析的报告方面也存在异质性。方法学方法中存在的相当大差异可能会影响结果。减少 SDDT 的管理、分析和报告方面的差异将提高严谨性和可重复性，并最大限度地发挥任务的巨大潜力。
