This study investigates the convergent and predictive validity of behavioral crime scene indicators of sexual sadism in the context of rape and sexual homicide. The study is based on a sample of 268 adult males sentenced to a federal penitentiary in Canada. Information regarding crime scene behaviors was gathered from police records, a clinical interview with a psychologist, and a semistructured interview with the offender. A series of logistic regressions were performed to determine whether behavioral crime scene indicators of sexual sadism were associated with an official diagnosis of sexual sadism and were able to distinguish between sexual aggressors against women and sexual murderers. Findings suggest that several crime scene behaviors overlap with an official diagnosis of sexual sadism as well as being able to distinguish between sexual aggressors of women and sexual murderers. Importantly, the majority of crime scene behaviors associated with a clinical diagnosis of sexual sadism are not the same as those associated with sexual homicide.
本研究在强奸和性杀人案件的背景下，调查性施虐行为犯罪现场指标的收敛效度和预测效度。该研究基于对268名被判处加拿大联邦监狱监禁的成年男性的样本。关于犯罪现场行为的信息来自警方记录、与心理学家的临床访谈以及对罪犯的半结构化访谈。进行了一系列逻辑回归分析，以确定性施虐行为犯罪现场指标是否与性施虐的官方诊断相关，以及是否能够区分针对女性的性侵犯者和性杀人犯。研究结果表明，一些犯罪现场行为与性施虐的官方诊断重叠，并且能够区分针对女性的性侵犯者和性杀人犯。重要的是，与性施虐临床诊断相关的大多数犯罪现场行为与性杀人相关的行为并不相同。
