Impulsivity is an important construct for understanding sexual behaviors, but behavioral and self-report measures of impulsivity often are not correlated. One possible explanation for this is that there is little shared variance in the measures because behavioral measures index impulsivity by asking questions about monetary preferences, while self-report measures index impulsivity by asking about a broad range of real-world outcomes (including those of a sexual nature) largely unrelated to money-related preferences. Undergraduate students (total N = 105; female n = 77, male n = 28) completed laboratory measures-delay discounting (DD) and probability discounting (PD)-for two different outcomes-money and sexual activity. Participants also completed the Delaying Gratification Inventory (DGI), which measures difficulty with delaying gratification (i.e., impulsivity) across different domains, including money and physical pleasures. Findings indicated that DD and PD for money were not related to any of the DGI subscales. However, DD for sexual activity was significantly related to the DGI Physical Pleasures subscale, but not other subscales. These findings suggest that the relationship between behavioral and self-report measures of impulsive choice may be stronger when both are measuring domain-specific rather than domain-general behavioral patterns, but further research is warranted.
冲动性是理解性行为的一个重要结构，但行为和自我报告的冲动性测量通常不相关。对此的一个可能解释是，这些测量方法之间的共同方差很小，因为行为测量通过询问关于货币偏好的问题来衡量冲动性，而自我报告的测量则通过询问与货币偏好关系不大的广泛的现实结果（包括性方面的结果）来衡量冲动性。本科学生（总人数=105；女性 n=77，男性 n=28）完成了两个不同结果（金钱和性活动）的实验室测量——延迟折扣（DD）和概率折扣（PD）。参与者还完成了延迟满足量表（DGI），该量表衡量在不同领域（包括金钱和身体愉悦）延迟满足的难度（即冲动性）。研究结果表明，金钱的 DD 和 PD 与 DGI 的任何一个分量表都没有关系。然而，性活动的 DD 与 DGI 的身体愉悦分量表显著相关，但与其他分量表无关。这些发现表明，当两者都在测量特定领域而非一般领域的行为模式时，行为和自我报告的冲动性选择测量之间的关系可能更强，但需要进一步的研究。
