Although a considerable amount of research has been conducted examining the validity of psychopathy as a psychological construct, relatively few studies have focused on the effects of using this disorder in "real-world" settings to influence the attitudes of laypersons who are making life-altering decisions about offenders. This study attempted to replicate and extend earlier findings (Guy & Edens, 2003) suggesting that there are gender differences in the impact of expert testimony regarding psychopathy. A sample of 599 undergraduates reviewed case facts regarding a hypothetical Sexually Violent Predator trial in which the type of risk assessment testimony provided (clinical opinion, actuarial scale, psychopathy evaluation) and the age of the victims (adult versus child) were manipulated. Consistent with prior research, despite overall high rates of support for commitment in the adult victim condition, men were less prone than women to support civil commitment when the defendant was described as "a psychopath" (62.5 versus 86.5%). No such gender differences were noted in the clinical opinion or actuarial conditions. When the victims were identified as children, type of testimony had no impact because support for commitment was almost unilateral. Finally, ratings of how psychopathic the defendant was perceived to be (regardless of the testimony provided) were significantly associated with support for commitment across most conditions.
尽管已经开展了大量研究来检验心理变态作为一种心理结构的有效性,但相对较少的研究关注在“现实世界”环境中使用这种障碍来影响对罪犯做出改变生活决定的外行人的态度所产生的影响。本研究试图复制并扩展早期的研究结果(盖伊和伊登斯,2003年),这些结果表明,关于心理变态的专家证词的影响存在性别差异。599名本科生参与了一项研究,他们审阅了关于一个假设的性暴力捕食者审判的案件事实,其中提供的风险评估证词类型(临床意见、精算量表、心理变态评估)和受害者年龄(成人与儿童)是被操纵的变量。与先前的研究一致,尽管在成年受害者情况下总体上支持关押的比例很高,但当被告被描述为“心理变态者”时,男性比女性更不容易支持民事关押(62.5%对86.5%)。在临床意见或精算条件下未发现此类性别差异。当受害者被确定为儿童时,证词类型没有影响,因为对关押的支持几乎是一边倒的。最后,在大多数情况下,对被告被认为有多心理变态的评分(无论提供何种证词)与对关押的支持显著相关。
