Biases associated with volunteering for studies in human sexuality were studied. Beginning with a sample of over 1000 introductory psychology students, subjects participated in a two-phase study in which those willing and unwilling to volunteer for a variety of sexuality studies were compared. In both phases of this study, volunteers were significantly different from nonvolunteers on some, but not all, dimensions assessed. Specifically, compared to nonvolunteers, volunteers reported a more positive attitude towards sexuality, less sexual guilt, and more sexual experience. These differences were independent of subject gender. Sobering implications of these findings for the generalizability of sexuality research results are discussed.
对参与人类性行为研究的志愿者相关偏差进行了研究。从1000多名心理学入门课程的学生样本开始，受试者参与了一项两阶段研究，在该研究中，对愿意和不愿意参与各种性行为研究的学生进行了比较。在这项研究的两个阶段中，志愿者和非志愿者在一些（但并非所有）评估维度上存在显著差异。具体而言，与非志愿者相比，志愿者对性行为的态度更为积极，性内疚感更少，性经验更多。这些差异与受试者的性别无关。讨论了这些发现对性行为研究结果普遍性的严峻影响。
