Sexual sadism and psychopathy are often considered synonymous with sexual homicide, but there is limited research on their associates in sexual homicide offenders. Associates of dimensional measures of sexual sadism (Sexual Sadism Scale; SeSaS) and psychopathy (Psychopathy Check List-Revised [PCL-R] total, Factor 1, and Factor 2) were examined in 51 male Scottish cases. Over a third were () sexual sadists, just under a third screened in with the SeSaS, and a quarter were "Hare psychopaths." Sexual sadism and PCL-R measures were moderately associated. Sexual sadism predicted control, sexual deviance, and unusual behaviour at crime scenes; attempted homicide and having a co-accused; and multiple sexual homicides and previous sexual offending. PCL-R Factor 1 predicted violent, exploitative, and evading detection behaviours at crime scenes; completed homicide; and previous violent offending. PCL-R Factor 2 predicted impulsive behaviours at crime scenes, substance misuse, and previous general offending. Psychopathy and sexual sadism play key roles in sexual homicide, interact with each other, and determine different aspects of offences and offenders.
性施虐癖和精神病态常被视为与性杀人同义，但关于性杀人罪犯中它们的相关因素的研究有限。在51例苏格兰男性案件中，对性施虐癖（性施虐量表；SeSaS）和精神病态（修订版精神病态量表[PCL-R]总分、因子1和因子2）的维度测量相关因素进行了研究。超过三分之一的人是（）性施虐者，略低于三分之一的人通过SeSaS筛查出来，四分之一的人是“哈雷精神病患者”。性施虐癖和PCL-R测量结果呈中度相关。性施虐癖预示着在犯罪现场的控制、性偏差和异常行为；未遂杀人及有共同被告；以及多起性杀人案和先前的性犯罪。PCL-R因子1预示着在犯罪现场的暴力、剥削和逃避侦查行为；完成杀人；以及先前的暴力犯罪。PCL-R因子2预示着在犯罪现场的冲动行为、药物滥用和先前的一般犯罪。精神病态和性施虐癖在性杀人中起关键作用，相互作用，并决定犯罪和罪犯的不同方面。 （注：原文括号处内容缺失）
