精神病态暴力犯执行功能的缺陷*

为了解精神病态罪犯可能存在的执行功能缺陷及其是否受冲动性影响,研究采用精神病态检核表（PCL-R）筛选出30名精神病态组被试和30名非精神病态组被试,通过爱荷华赌博任务（IGT）和河内塔任务（TOH）对两组被试执行功能的特点进行分析,并结合冲动性量表（BIS-11）对其冲动性进行测量。研究发现精神病态组的冲动性显著高于控制组;精神病态组选择高风险的不利牌显著多于对照组,即对惩罚不敏感;精神病态组在河内塔任务中的错误次数及所消耗时间都显著高于控制组;冲动性水平与两任务得分均无显著相关。结果表明,精神病态暴力犯在与前额叶相关的执行功能上存在缺陷,并与个体的高冲动性无关。     

国外精神病态罪犯的脑机制研究述评

精神病态是一种个体表现在人际关系、情感、生活方式和反社会特质等方面的人格障碍, 与非精神病态者相比, 精神病态者更容易违反社会规则和法律, 表现出更加残忍和极端的侵犯模式, 犯罪的起始年龄更早, 犯罪活动更为广泛和多样, 累犯率非常高。国外关于精神病态罪犯脑机制的ERP研究表明精神病态罪犯注意朝向、语义和情感加工以及对错误加工的后期阶段存在缺陷。MRI和fMRI的研究表明, 大脑结构异常以及额叶-边缘系统回路活动异常与精神病态行为有关。     

精神病态的家庭风险因素

精神病态(psychopathy)是一种个体表现在人际关系、情感、生活方式和反社会特征等方面的人格障碍, 其特征为自我中心、欺骗、冲动、缺乏共情、缺乏罪恶感等。以往研究偏向于精神病态的生理机制, 认为精神病态具有高度的遗传性, 近期越来越多的研究发现家庭因素对精神病态的重要影响。这些因素包括：产前风险因素、破碎家庭、不良的教养方式、不安全的亲子依恋关系和童年期虐待等。未来的研究应探讨家庭因素对各个精神病态亚型的作用机制, 探索抑制精神病态表达的保护性环境因子, 并构建精神病态的生物心理社会模型等。     

220名男性罪犯人格障碍的初步研究

采用人格障碍诊断量表和艾森克人格问卷,对在押的220名男性罪犯的人格障碍及人格特征进行调查,结果发现：（1）罪犯人格障碍的发生率显著高于普通人群,且与普通人群存在极显著的差异。（2）罪犯人格障碍与艾森克人格量表中情绪稳定性、精神质、内外向三个因素有显著的相关。其中,情绪稳定性因素与12种类型人格障碍及总分存在极显著的正相关;精神质因素与除强迫型以外的11种类型的人格障碍及总分存在极显著的正相关;内外向因素与表演型、反社会型人格障碍以及自恋型人格障碍存在显著的正相关,与分裂样人格障碍存在显著的负相关。情绪稳定性因素可能是各型罪犯人格障碍的基本人格因素。     

男性罪犯人格和抑郁的关系研究

该研究采用问卷法{中国罪犯个性分测验量表（COPA—PI）、自评抑郁量表（SDS）},对在押的200名男性犯人的人格和抑郁的关系进行研究,结果发现：1）人格和抑郁之间存在着显著相关关系。2）混合型罪犯在人格因子“同情”上的得分显著低于暴力型罪犯,在“暴力倾向”上的得分显著高于财产型罪犯,在“变态心理”和抑郁上的得分显著高于财产型和暴力型罪犯。3）有前科罪犯的抑郁分数显著高于无前科罪犯。4）“焦虑”、“聪敏”、“波动”、“同情”四个人格因子对罪犯的抑郁情绪有显著预测力。为罪犯矫治工作提供了科学的理论依据和指导。     

大学生幽默风格与精神健康关系的初步研究

目的:测试幽默风格量表在中国大学生中的信度和效度,探讨幽默风格与精神健康之间的关系。方法:354名大学生接受幽默风格量表和症状自评量表(SCL-90)的问卷调查,4周后74名大学生重新填写幽默风格量表。结果:幽默风格量表所提出的4个因子结构在中国人的样本中也存在,该量表的信度和效度可接受。中国被试在4个子量表的得分均低于加拿大被试的得分。亲和型幽默、自强型幽默得分与症状自评量表的子量表以及总体症状指数得分全部呈现负相关,而嘲讽型幽默和自贬型幽默得分与症状自评量表的子量表以及总体症状指数得分全部呈现正相关。结论:(1)该量表的初步测试效度和信度可接受,但须结合中国文化作进一步的修订;(2)亲和型和自强型幽默有益于精神健康,但嘲讽型和自贬型幽默有害于精神健康;(3)中国人与加拿大人在幽默风格、幽默对精神健康起作用的方式上存在一定的文化差异。     

基于三元精神病态模型的精神病态认知-情感加工框架

精神病态作为暴力犯罪、累犯和青少年犯罪的重要预测变量, 在临床心理学和司法领域受到了广泛重视。三元精神病态模型通过大胆、卑劣和去抑制三个维度对精神病态进行了操作化定义, 反映了精神病态在神经生物学维度上存在的认知情感加工缺陷。其中, 低威胁敏感性是精神病态大胆的主要病因学基础; 而执行功能受损, 尤其是注意调节缺陷则导致了精神病态的去抑制倾向; 而与情绪识别存在联系的共情缺陷可能是卑劣的深层原因。未来研究中仍需关注精神病态的概念化问题, 以及不同精神病态特质之间是否存在共同的潜在病因学基础, 探索精神病态特质在生命早期阶段的体现从而进行及时有效的干预。     

正念训练对睡眠质量与日间警觉性的影响

为考察正念对睡眠质量与日间警觉性的影响,本研究将参与实验的被试分为正念组与控制组,在八周训练前后,采用五因素正念度量表(FFMQ)、匹兹堡睡眠质量指数量表(PSQI)与精神运动警觉性测试(PVT)进行测量。结果显示:(1)正念组的后测FFMQ得分显著高于前测,后测PVT任务反应时、反应延迟数与完成任务的疲劳自评差值显著低于前测,控制组前、后测无显著差异;(2)正念组的前测PSQI睡眠障碍维度得分显著高于控制组前测,而两组后测差异不显著。研究证明,正念训练可以提升个体正念水平与日间警觉性水平,并一定程度上改善个体的睡眠质量。

黑暗人格三合一研究述评

如果说大五人格代表了特质论人格心理学对非临床人格的研究成果,近期出现的黑暗人格三合一则代表了对亚临床人格阴暗面的研究成果。黑暗人格三合一由马基雅维利主义、自恋和精神病态三种人格特质构成,这三种人格特质在西方文化中均属于反社会型人格特质。对黑暗人格三合一的研究发现:(1)马基雅维利主义、自恋和精神病态各自独立又相互交织;(2)它们的测量工具均较为成熟;(3)黑暗人格三合一不仅具有反社会性,也具有亲社会性;(4)黑暗人格三合一反映个体的快速生命策略;(5)遗传和环境因素在黑暗人格三合一的形成中发挥不同作用;(6)黑暗人格三合一是不同于大五人格的人格特质群。     

Cross-national differences in the assessment of psychopathy: do they reflect variations in raters' perceptions of symptoms?

Cross-national differences in the prevalence of psychopathy have been reported. This study examined whether rater effects could account for these differences. Psychopathy was assessed with the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). Videotapes of 6 Scottish prisoners and 6 Canadian prisoners were rated by 10 Scottish and 10 Canadian raters. No significant main or interaction effects involving the nationality of raters were detected at the level of full scores or factor scores. Using a generalizability theory approach, it was demonstrated that the interrater reliability of total scores was good, that is, the proportion of variance in test scores attributable to raters was small. The interrater reliability of factor scores was lower, typically falling in the fair range. Overall, the results suggest that the reported cross-national differences are more likely to be in the expression of the disorder rather than in the eye of the beholder.     

Examining the utility of the PCL:SV as a screening measure using competing factor models of psychopathy

The correspondence between the Hare Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) and the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) was examined in forensic (N = 175) and correctional (N = 188) samples. Intermeasure correlations for Total scores (.95 forensic, .94 correctional) and the original 2-factor, D. J. Cooke and C. Michie's (2001) 3-factor, and R. D. Hare's (2003) 4-facet models (range = .87-.95) were high. Area under the curve values for the PCL:SV were .98 in both samples (cutoff = PCL-R Total score of 25). The PCL:SV performed well as a screen, maximizing false positive relative to false negative errors. Close correlations for prediction of violent recidivism in the correctional sample were obtained for the PCL-R (.42) and PCL:SV (.37). Results indicate the robust relation between the measures is maintained whether they are completed on the basis of file review only or file plus interview and whether the same or different raters score the measures.     

Four-facet PCL-R structure and cognitive functioning among high violent criminal offenders

High violent inmates (N = 126) were administered the Psychopathy Checklist-Revised (PCL-R; Hare, Clark, Grann, & Thornton, 2000; Hare et al., 1990) and neuropsychological measures. No significant correlations were present between the overall PCL-R score and 14 cognitive measures. A violence score, computed as the total number of violent acts across all situations and types, was significantly correlated with the PCL-R total score and Facet 2 but not with the other three facets. Our data suggest that Facet 2 elevations may prove relevant to violence risk assessment; this link, however, needs further exploration with larger samples.     

The interpersonal measure of psychopathy: construct and incremental validity in male prisoners

The authors examined the construct and incremental validity of the Interpersonal Measure of Psychopathy (IM-P), a relatively new instrument designed to detect interpersonal behaviors associated with psychopathy. Observers of videotaped Psychopathy Checklist-Revised (PCL-R) interviews rated male prisoners (N = 93) on the IM-P. The IM-P correlated significantly with the PCL-R total score. Moreover, the IM-P was preferentially related to the interpersonal rather than the affective and antisocial lifestyle features of psychopathy. IM-P scores were significantly correlated with age, antisocial behaviors, and self-reported fear, anxiety, and socialization (in reverse). Hierarchical multiple regression analyses demonstrated that although the IM-P exhibited incremental validity beyond the PCL-R total score in detecting self-reported fear, anxiety, and several personality traits, it did not exhibit much incremental validity beyond PCL-R Factor 1. These findings raise questions concerning the unique assessment contribution of the IM-P beyond PCL-R Factor 1. Potential reasons for these findings and alternative means of enhancing the interpersonal assessment of psychopathy are discussed.     

Incremental validity of the Psychopathy Checklist facet scores: predicting release outcome in six samples

The incremental validity of the 4 facet scores (Interpersonal, Affective, Lifestyle, Antisocial) of the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) and the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was evaluated in 6 forensic/correctional samples with average follow-ups ranging from 20 weeks to 10 years. Results indicated that whereas Facet 4 (Antisocial) achieved incremental validity relative to the first 3 facets (Interpersonal, Affective, and Lifestyle) in predicting recidivism in all 6 samples, a block of the first 3 facets achieved incremental validity relative to the 4th facet in only 1 sample. Thus, although there was consistent support for the incremental validity of Facet 4 above and beyond the first 3 facets, there was minimal support for the incremental validity of Facets 1, 2, and 3 above and beyond Facet 4. The implications of these findings for the psychopathy construct in general and the PCL-R/SV in particular are discussed.     

Capturing the four-factor structure of psychopathy in college students via self-report

A number of self-report psychopathy scales have been used successfully in both clinical and nonclinical settings. However, their factor structure does not adequately capture the four factors (Interpersonal, Affective, Lifestyle, and Antisocial) recently identified in the Psychopathy Checklist-Revised (PCL-R; Hare, 2003) and related measures. This deficit was addressed by upgrading the Self Report Psychopathy Scale (SRP-II; Hare, Hemphill, & Harpur, 1989). In Study 1 (N = 249), an exploratory factor analysis of this experimental version revealed oblique factors similar to those outlined by Hare (2003). In Study 2 (N = 274), confirmatory factor analysis (CFA) confirmed this structure, that is, four distinct but intercorrelated factors. The factors exhibited appropriate construct validity in a nomological network of related personality measures. Links with self-reports of offensive activities (including entertainment preferences and behavior) also supported the construct validity of the oblique four-factor model.     

Hare Psychopathy Checklist-Revised

The Hare Psychopathy Checklist-Revised (PCL-R) is among the most frequently used instruments for the assessment of psychopathic traits. In the scope of the German adaptation of the PCL-R, normative data were collected from a sample of adult male offenders. Based on these data the factor structure and reliability of the German language version of the PCL-R are discussed in the first section of the article. The assessment of a model with four facets and two superordinate factors showed a very good agreement with the empirical data. In addition, examination of interrater agreement and internal consistency indicated that the PCL-R is a reliable measure. In the second part of the paper recommendations are provided for the correct application of the PCL-R. The focus lies on the correct performance, evaluation and interpretation of PCL-R test results with respect to key indices and the dimensional structure of the psychopathy construct.     

Response perseveration in psychopaths: Interpersonal/affective or social deviance traits?

In order to clarify the role of the two broad components of psychopathy (interpersonal/affective and social deviance; R. D. Hare, 2003) in explaining maladaptive response perseveration in psychopaths, as well as the role of reflection after punished responses in this deficit, the authors administered a card perseveration task to 47 Spanish male inmates assessed using the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). Hierarchical regressions showed that psychopaths' maladaptive perseveration (more cards played and less money earned) was uniquely predicted by the social deviance features of psychopathy (PCL-R Factor 2)--particularly by its impulsive and irresponsible lifestyle facet (PCL-R Facet 3)--and not by its interpersonal/affective features (PCL-R Factor 1). Moreover, perseveration was related to a lack of reflection both after punishment and after reward feedback. The authors' results, in conjunction with previous evidence indicating perseverative deficits in several impulse control disorders, suggest that response perseveration may not be specific to psychopathy but rather is associated more generally with the externalizing dimension of psychopathology.     

A multigroup item response theory analysis of the psychopathy checklist--revised

Item response theory was used to investigate the functioning of the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) in several offender populations. With male criminal offenders (N=3,847) as a reference group, differential item functioning analyses were performed for 3 comparison groups: female criminal offenders (N=1,219), male forensic psychiatric patients (N=1,246), and male criminal offenders scored from file reviews (N=2,626). Results are discussed in the context of the 2-factor, 4-facet model for the PCL-R (R. D. Hare, 2003; J. Parker, G. Sitarenios, & R. D. Hare, 2003). Application of a multigroup graded response model to all 4 groups suggests scalar equivalence may hold at least approximately for each population, although the PCL-R provided slightly greater information about the latent trait of psychopathy for male criminal offenders scored from the standard procedure.     

Does treatment really make psychopaths worse? A review of the evidence

We aimed to evaluate critically the evidence behind the perceived inverse association between the degree of psychopathy as reflected by a high score on the Hare Psychopathy Checklist-Revised (PCL-R) and treatment response. A literature search with the key identifiers of PCL-R (or its derivatives) and treatment response produced 24 studies that were then systematically evaluated. This showed that only three studies were of an appropriate research design to answer the question and of these, none met our standard for an acceptable study. We conclude therefore that the commonly held belief of an inverse relationship between high-scores on the PCL-R and treatment response has not been established.
