Nonconsensual sexual experiences (NSEs) may contribute to mental health concerns among incarcerated individuals, yet NSEs are understudied in this population. This study takes a novel approach in examining the prevalence of NSEs among incarcerated males by utilizing both quantitative and qualitative measures. The sample consisted of 189 men from three provincial maximum-security prisons in Ontario, Canada. Based on quantitative findings, 44.2% of the sample experienced NSEs before the age of 18, and 41.7% of the sample endorsed an experience that fit the legal definition of a NSEs as adults. Participants also responded to a qualitative open-ended question about their history of NSEs. Based on qualitative findings, a total of 23% of the men reported at least one incident of a NSE (e.g., child and adult). Based Findings highlight the high prevalence of NSEs among incarcerated men with quantitative responses demonstrating how the use of a behavioral questionnaire may, to some extent, correct for underreporting of NSEs. Qualitative responses illustrate the lived experience of incarcerated men and provide a deeper understanding of their NSEs. Responses also speak to the lack of resources and support available to these men. Findings underscore the need for proactive approaches in meeting mental health needs of incarcerated men in general and with regard to NSEs in particular. Results may inform the development of future correctional procedures (i.e., intake protocols that account for men with NSEs) and resources to support incarcerated men in navigating the psychological impact of non-consensual sexual experiences.

非自愿性经历（NSE）可能会导致被监禁者的心理健康问题，但该人群中的 NSE 尚未得到充分研究。这项研究采用了一种新颖的方法，通过定量和定性措施来检查被监禁男性中 NSE 的患病率。样本由来自加拿大安大略省三座省级最高安全监狱的 189 名男子组成。根据定量研究结果，44.2% 的样本在 18 岁之前经历过 NSE，41.7% 的样本认可符合成年人 NSE 法律定义的经历。参与者还回答了有关其 NSE 历史的定性开放式问题。根据定性调查结果，共有23% 的男性报告至少发生过一次 NSE（例如儿童和成人）。基于调查结果强调了被监禁男性中 NSE 的高患病率，并通过定量反应证明了行为问卷的使用可以在某种程度上纠正 NSE 的漏报情况。定性回答展示了被监禁男子的生活经历，并提供了对其 NSE 的更深入的了解。回应还表明这些人缺乏可用的资源和支持。研究结果强调，需要采取积极主动的方法来满足一般被监禁男子的心理健康需求，特别是 NSE 方面的需求。结果可能会为未来惩教程序（即考虑患有 NSE 的男性的收治方案）和资源的制定提供信息，以支持被监禁的男性应对非自愿性经历的心理影响。
