Psychopathy and sexual sadism

Psychopathic Personality as a Moderator of the Relationship Between Atypical Sexuality and Sexual Coercion Proclivity in the General Population

Being sexually coerced can have long-lasting psychological impacts on victims; with perpetration strongly predicted by elevated psychopathic traits. Owing to recent legislative developments in the United Kingdom that criminalize coercive control under the Domestic Abuse Act (2021), this study offers a timely investigation into the mechanisms of sexual coercion in domestic abuse across sexual abuse and coercive control. We used moderation analysis (n = 405) to investigate whether sexual coercion proclivity was predicted by facets of atypical sexuality (non-clinical elevated levels of sex drive, sexual sadism, and sexual masochism), and whether this relationship was moderated by psychopathic personality traits specifically the factor one components, which encompasses interpersonal and affective characteristics. Psychopathic personality traits significantly moderated the positive association between sex drive and sexual coercion proclivity, and between sexual sadism and sexual coercion proclivity in males (but not females), but psychopathic personality traits had no such moderating effect in the sexual masochism model. Results are discussed in terms of identifying risk factors of sexual coercion within a general population sample and international application.

What if Marquis de Sade Was a Woman? New Evidence of Sex Differences in Behavioral Manifestation of Sadism

This study aims to explore the behavioral manifestation of sadism in females involved in sexual crimes. The sample includes 24 female sex offenders for which sadism was assessed with the SeSaS. To conduct a gender-based comparison analysis, we conducted a random selection of 100 sadistic male offenders. Bivariate comparisons and multidimensional scaling analysis were used to determine whether behavioral manifestation and dimensions of sadism are different in female sex offenders. Results showed that sadism in women manifests itself differently from male offenders and practical implications are discussed.

Dark Tetrad personality traits, paraphilic interests, and the role of impulsivity: an EEG-study using a Go/No-Go paradigm

Maladaptive personality traits, such as 'dark personalities' are found to result in a diverse set of negative outcomes, including paraphilic interests and associated (illegal) behaviors. It is however unclear how these are exactly related, and if related, if then only those individuals higher on dark personality traits and higher impulsivity engage in paraphilic behaviors. In the current study, 50 participants were recruited to investigate the relationship between Dark Tetrad personality traits (i.e., narcissism, psychopathy, Machiavellianism and everyday sadism), paraphilic interests (arousal and behavior) and the moderating role of impulsivity. Personality and paraphilic interests were investigated through self-report questionnaires. Impulsivity was measured both through self-reported dysfunctional impulsivity and the P3 event related potential using electroencephalography during the Go/No-Go task (i.e. response inhibition). The results showed that there was a positive association between psychopathy, sadism and paraphilic interests. Whereas everyday sadism was associated with paraphilic (self-reported) arousal, psychopathy was associated with paraphilic behavior. Although P3 amplitude was not associated with paraphilic interests, self-reported dysfunctional impulsivity was associated with paraphilic behavior specifically. However, there was no moderating role of dysfunctional impulsivity and response inhibition (P3) in the relationship between psychopathy and paraphilic behavior. Findings indicate that the relation between specific dark personalities and paraphilic interests may be more complex than initially thought. Nevertheless, risk assessment and intervention approaches for paraphilia and related behavior both may benefit from incorporating Dark Tetrad and impulsivity measurements.

Diagnosing psychopathy in an intercultural setting: Applications and implications in postcolonial contemporary Mayotte

International scientific research has extensively studied psychopathy, but few studies focus on an intercultural and postcolonial context. Mayotte, a French overseas collectivity located in East Africa, offers a unique opportunity to study the application and effects of psychopathy diagnosis in the criminal justice field within a social context shaped by colonial legacy. This research uses a mixed-method approach, combining quantitative and qualitative data, to show that in Mayotte, the majority of individuals diagnosed with psychopathy are young, low-income individuals who act in groups. Among them are minors, and the majority have no prior criminal history. This article provides a complementarist reflection on this phenomenon, informed by immersive field anthropology and theoretical contributions from psychology, sociology, and criminology. Through an inductive research process, this study posits the hypothesis that diagnoses of psychopathy in post-colonial contexts may be influenced by complex determinants rooted in collective history and contemporary power relations.

Psychological and Developmental Correlates of Paraphilic and Normophilic Sexual Interests

The classification of sexual fantasies and behaviors (here referred to as 'sexual interests') has historically been divided into 'paraphilic' and 'normophilic'. However, studies on paraphilic interests are often limited to clinical or forensic samples and normophilic interests are rarely assessed in tandem. Previous research has found mixed results for psychological and other correlates of sexual interests, potentially due to inconsistency in operationalism and measurement of fantasies and behaviors. The aim of the current study was to quantify correlates of sexual interests via the Sexual Fantasies and Behaviors Inventory, containing factors related to general fantasies/behaviors, normophilia, power dynamics, sadomasochism, and courtship paraphilias, using a large (N = 4280) non-clinical sample. Psychological, developmental, sexual, and demographic correlates were investigated via bivariate correlations, mean difference testing, and multiple regression. Sexual interest domains were largely unrelated to psychopathology and developmental factors. Sociosexuality and more accepting attitudes towards sadomasochism was generally related to more arousal to/engagement in normophilic and paraphilic domains. More autism spectrum disorder traits were related to decreased normophilic interests. Psychopathic traits, sexual sensation seeking, and sexual compulsivity were related to paraphilia dimensions, especially courtship paraphilias and domination/sadism; the former was also associated with negative attitudes about establishing consent. Men, non-monogamous, and non-heterosexual participants indicated greater sexual fantasies and behaviors compared to women (except in the case of submission and masochism), monogamous, and heterosexual participants, respectively.

Your pain, my gain: The relationship between self-report and behavioral measures of everyday sadism and COVID-19 vaccination intention

Vaccination plays a crucial role in containing the spread of the COVID-19 pandemic. However, a significant fraction of the global population is reluctant to take a coronavirus vaccine. A burgeoning literature has considered mainly adaptive personality traits as antecedents of vaccine hesitancy (i.e., Big Five and HEXACO), while maladaptive personality traits (i.e., "Dark Tetrad" of personality) are often a comparatively neglected area. In this research, we examined the relationship between everyday sadism and intention to get vaccinated against COVID-19. We theorized that driven by antisocial tendencies and social indifference, individuals with higher sadism may be less willing to obtain a vaccine. Employing a bug-killing paradigm to capture everyday sadism, we tested this prediction in a Chinese sample of non-student adults (N = 188). Support for this proposition was found in the lab task, which demonstrates that sadism was associated with more vaccine refusal spanning the self-report and behavioral domains. In addition, we showed that the sadistic behavioral choices can be predicted with self-report measure of sadistic personality. These findings highlight the important role of maladaptive personality traits in predicting vaccination attitudes and intentions.

Emotional intelligence in incarcerated sexual offenders with sexual sadism

Emotional intelligence (EI) is defined by the ability to perceive, manage, and reason about emotions in oneself and others. Studies have reported deficits in EI abilities among certain antisocial populations such as individuals with psychopathy, and enhanced performance among sexual offenders. Despite EI's relevance to offending behaviour, the association between EI and paraphilic offending has been under-studied. We examined the association between EI, sexual offending, and sexual sadism in 80 incarcerated men with sexual offenses and 207 incarcerated men with non-sexual offences. EI was assessed using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Sadism was measured using the Severe Sexual Sadism Scale (SeSaS). Results showed that SeSaS scores were positively associated with Strategic EI (the ability to understand and manage emotions), but were not significantly related to Experiential EI. This may reflect core characteristics of sexual sadism including domination and manipulation, challenging the prevalent notion that higher EI is invariably positive.

Rational, emotional, or both? Subcomponents of psychopathy predict opposing moral decisions

Recent research has documented a small but significant correlation between psychopathic capacities and utilitarian moral judgment, although the findings are generally inconsistent and unclear. We propose that one way to make sense of mixed findings is to consider variation in perspective-taking capacities of psychopathic individuals. With this in mind, we had criminal offenders (n = 60), who varied in their psychopathy levels according to the Psychopathy Checklist-Revised (PCL-R), respond to common sacrificial moral dilemmas (e.g., trolley dilemmas) under different conditions. In a baseline condition, participants simply responded to the sacrificial moral dilemmas as is typically done in previous research. In an "emotion-salient" condition, participants had to reason about the emotions of another person after solving moral dilemmas (deliberative processing). In the "emotion-ambiguous" condition, participants saw images of people in distress, after solving moral dilemmas, but did not have to explicitly reason about such emotions (spontaneous processing). The four PCL-R facets predicted distinct interference effects depending on spontaneous versus deliberative processing of hypothetical victim's emotions. The findings suggest that the use of a multi-faceted approach to account for cognitive and moral correlates of psychopathy may help address previously mixed results. Implications and future directions for theory and research are discussed.

Neural Correlates of Moral Judgment in Criminal Offenders with Sadistic Traits

Sexual sadism is a paraphilia that focuses on domination, humiliation, and infliction of pain on a victim to stimulate sexual arousal. Although extensively described in psychology and forensic sciences, less is known about whether the harmful acts committed by sexual sadists are accompanied by deficits in moral judgment. A limited amount of behavioral research suggests moral insensitivity in sexual sadists; however, the neural networks underlying moral judgment in sadists have not been studied. In this pilot study, 21 incarcerated male sexual offenders with (n = 11) and without (n = 10) sexual sadism were scanned with functional magnetic resonance imaging (fMRI) while they viewed pictures that did or did not depict situations considered by most individuals to represent moral transgressions, and rated their degree of moral transgression severity. Results indicated primarily overlapping neural systems underlying moral judgment in sadists and non-sadists. However, non-sadists but not sadists showed a positive correlation between moral transgression severity ratings and activity in the anterior temporal cortex (ATC). This lack of ATC engagement in sadists might be a biomarker of altered moral judgment.

Characteristics and Behaviors of Anonymous Users of Dark Web Platforms Suspected of Child Sexual Offenses

International law enforcement have noted a rise in the use of the Dark Web to facilitate and commit sexual offenses against children, both prior to and since the start of the COVID-19 pandemic. The study presented here therefore aimed to investigate the characteristics and behaviors of anonymous users of Dark Web platforms who were suspected of engaging in the sexual abuse of children. Naturally-occurring data on 53 anonymous suspects, who were active on the Dark Web and had come to police attention in the United Kingdom (UK), were sampled. Analysis of the data yielded 462 features that could be coded reliably. Analysis of these features provided novel insights into suspects’ characteristics, their motivations for using the Dark Web, the nature of the offending behavior they reported engaging in, their technical and security precautions, sexual interests, and the content of their interactions with one another. Findings are discussed in relation to theoretical and practical implications, as well as directions for future research.

Sexual homicide in Australia and New Zealand: a description of offenders, offences and victims

The field of sexual homicide research is relatively recent, with many existing studies limited by small sample sizes and sampling bias. In Australia and New Zealand specifically, only one study to date addresses this phenomenon but there is a lack of comprehensive descriptive data. This study aims to fill this research gap using a representative sample gathered from public legal databases. A total of 118 cases of sexual homicide offenders are described to create a portrait of this type of offender, their victims and their offence behaviour. Findings are similar to those found in other large samples from the UK, Canada and Germany. Because this crime is rare and practitioners tend to have limited experience of them, the findings of this research have the potential to inform investigative, criminal justice and clinical practice.

Cognitive, Affective, and General Empathy in Individuals Convicted of a Sexual Offense: A Meta-Analysis

Empathy has an important role in promoting proper societal functions. Those who violate societal functions, such as those convicted of having committed a criminal offense, are theorized to possess deficits in their empathic capacity. This assumption has been adopted by many criminological models, including for individuals convicted of a sexual offense (ICSO). However, contradictory research results have resulted in conflicting theories regarding the level of empathy within ICSO. This meta-analysis compiled available data to provide empirical clarity in a divided theoretical field. Results of the meta-analysis indicate that ICSO have lower levels of cognitive (Hedges's g = -.303, p = .007) and general empathy (Hedges's g = -.188, p = .020) than those in the general population but do not have significantly lower levels of affective empathy (Hedges's g = .023, p = .849). Several moderator analyses were conducted, including type of sexual offense, assessment instrument used, and age at conviction.

Screening for Dark Personalities

Abstract. Consensus is emerging that the constellation of dark personalities should include the sadistic personality. To build a four-factor measure, we modified and extended the Short Dark Triad (SD3) measure to include sadism. A series of three studies yielded the Short Dark Tetrad (SD4), a four subscale inventory with 7 items per construct. Study 1 ( N = 868) applied exploratory factor analysis (EFA) to a diverse 48-item pool using data collected on MTurk. A 4-factor solution revealed a separate sadism factor, as well as a shifted Dark Triad. Study 2 ( N = 999 students) applied EFA to a reduced 37-item set. Associations with adjustment and sex drive provided insight into unique personality dynamics of the four constructs. In Study 3 ( N = 660), a confirmatory factor analysis (CFA) of the final 28 items showed acceptable fit for a four-factor solution. Moreover, the resulting 7-item subscales each showed coherent links with the Big Five and adjustment. In sum, the four-factor structure replicated across student and community samples. Although they overlap to a moderate degree, the four subscales show distinctive correlates – even with a control for acquiescence. We also uncovered a novel link between sadism and sexuality, but no association with maladjustment.

The Unusual Suspects: Multiple-Perpetrator and Multiple Concurrent Victim Sexual Homicide

Sexual homicide typically implies a crime involving two people: perpetrator and victim. Thus, multiple-perpetrator and multiple concurrent victim sexual murderers are unusual, empirically invisible due to their exclusion from (or burying within) research samples. The present study examines 21 such cases of male sexual murderers having perpetrated at least one sexual homicide either together with a co-offender or alone but killing two victims at once. The aim was to investigate just how unusual, or not, these cases may be in relation to current scientific understanding of sexual murderers and their crimes. A descriptive analysis of offenses (co-offender and offender-victim dynamics, modus operandi) and offender characteristics is presented. Main findings, that multiple-perpetrator and multiple concurrent victim sexual murderers are not so unusual in that they are well conceptualized through application of the established sexualized, grievance, and rape murderer typology, are discussed in relation to clinical and empirical implications.

Sexual Sadism and Psychopathy in Sexual Homicide Offenders: An Exploration of Their Associates in a Clinical Sample

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 DSM-IV (Diagnostic and Statistical Manual of Mental Disorders-IV) 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.

The Intensity and Timing of Sex Offender Treatment

Current evidence about the impact of specialized sex offender treatment on reoffending remains inconsistent, drawing attention to the need to focus more on those program characteristics that potentially moderate outcome. This review considers current professional perspectives and evidence on two defining aspects of treatment: its intensity and timing. It is concluded that insufficient evidence currently exists to articulate best practice in this area and there is a pressing need to collect empirical evidence about the effectiveness of different intensity treatments offered at different stages of sentence.

Dark and Peculiar

Abstract. Earlier research suggested that militant extremists could have certain aspects of psychopathic and psychotic characteristics. Relying on these studies, we investigated whether the Militant Extremist Mind-Set (MEM) could be explained by psychopathy, sadism, and Disintegration (psychosis proneness), as subclinical manifestations of amoral, antisocial, and psychotic-like traits. In Study 1 (306 undergraduate students), it was shown that sadistic and psychopathic tendencies were related to Proviolence (advocating violence as a means for achieving a goal); psychopathic and disintegrative tendencies were associated to the Vile World (belief in a world as a corrupted and vile place), while Disintegration was the best predictor of Divine Power (relying on supernatural forces as a rationale for extremist acts). In Study 2 (147 male convicts), these relations were largely replicated and broadened by including implicit emotional associations to violence in the study design. Thus, while Proviolence was found to be related to a weakened negative emotional reaction to violent pictures, Vile World was found to be associated with stronger negative emotions as a response to violence. Furthermore, Proviolence was the only MEM factor clearly differentiating the sample of convicts from male students who participated in Study 1. Results help extend current understanding about personal characteristics related to militant extremism.

Personality Disorder Features and Paraphilic Interests Among Undergraduates: Differential Relations and Potential Antecedents

We examined the relations between: (1) narcissism, psychopathy, DSM-5 personality disorder symptom counts; and (2) paraphilic interests among undergraduates (N = 608). Base rates of paraphilic interests were appreciable. The disinhibition and meanness features of psychopathy and the entitlement and exploitativeness features of narcissism were robustly associated with paraphilic interests, particularly sexual sadism, whereas the boldness features of narcissism and psychopathy were essentially unrelated to these interests. Narcissism and psychopathy features typically manifested the most pronounced relations with paraphilic interests, although antisocial personality disorder features were also strong predictors. By and large, these relations were comparable across gender. Lastly, there was no evidence that erotophilia mediated the relations between the narcissism and psychopathy features and paraphilic interests, most likely because erotophilia was generally unrelated to paraphilic interests. Relative to other dimensions of personality disorders, facets of meanness and disinhibition from psychopathy and entitlement/exploitativeness facets from narcissism were most associated with paraphilic interests.

Using latent variable- and person-centered approaches to examine the role of psychopathic traits in sex offenders

The current study employed both latent variable- and person-centered approaches to examine psychopathic traits in a large sample of sex offenders (N = 958). The offenders, who had committed a range of sexual crimes, had been assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four-factor model of psychopathy (Hare, 2003; Neumann, Hare, & Newman, 2007) provided good representation of the dimensional nature of psychopathic traits across the sample of offenders, and that the PCL-R factors significantly predicted sexual crimes. In particular, the Affective and Antisocial psychopathy factors each predicted sexually violent crimes. Latent profile analysis results revealed evidence for a 4-class solution, with the subtypes showing distinct PCL-R facet profiles, consistent with previous research. The four subtypes were validated using sexual crime profiles. The prototypic psychopathy subtype (high on all 4 PCL-R facets) evidenced more violent sexual offenses than did the other subtypes. Taken together, the results demonstrate how variable- and person-centered approaches in combination can add to our understanding of the psychopathy construct and its correlates.

Sadism and Violent Reoffending in Sexual Offenders

A diagnosis of sadism in sexual offenders is commonly regarded as indicative of high risk for violent reoffending. The purpose of the current two studies was to evaluate whether sadism is indeed associated with higher rates of violent (including sexual) reoffending. In Study 1 (meta-analysis), the rate of violent and sexual recidivism was assessed across seven samples of male sex offenders (total N = 2,169) as a function of diagnoses of sexual sadism. In Study 2 (N = 768) the outcome (violent recidivism yes/no) was regressed on sadism, along with behavioral indicators of sexually sadistic offending, and scores from violence risk assessment instruments. In Study 1 (meta-analysis), the overall risk of sadists compared with nonsadists with respect to violent (including sexual contact) reoffending was slightly elevated (by a factor of 1.18), yet not significantly increased. Similarly, the risk of sexual reoffending among sadists was slightly, but not significantly, higher than among nonsadists (factor 1.38). According to Study 2, only a measure of sadistic behavior, not the clinical diagnosis, was associated with violent reoffending. This association, however, was not present once age and customary risk assessment instruments for violence risk were included in the regression. A clinical diagnosis of sexual sadism and behavioral measures of sadism are related to the risk of violent reoffending in sexual offenders. These associations, however, are weak and do not hold once variables relevant for the prediction of violence are controlled for. At the individual level, the risk for future violence in sadists can therefore be adequately described by customary risk assessment instruments.

The Dark Tetrad

Abstract. Machiavellianism, narcissism, and psychopathy are personality traits understood to be dispositions toward amoral and antisocial behavior. Recent research has suggested that sadism should also be added to this set of traits. In the present study, we tested a hypothesis proposing that these four traits are expressions of one superordinate construct: The Dark Tetrad. Exploration of the latent space of four “dark” traits suggested that the singular second-order factor which represents the Dark Tetrad can be extracted. Analysis has shown that Dark Tetrad traits can be located in the space of basic personality traits, especially on the negative pole of the Honesty-Humility, Agreeableness, Conscientiousness, and Emotionality dimensions. We conclude that sadism behaves in a similar manner as the other dark traits, but it cannot be reduced to them. The results support the concept of “Dark Tetrad.”

Inverted social reward: associations between psychopathic traits and self-report and experimental measures of social reward

Individuals with high levels of psychopathic traits tend to undervalue long-term, affiliative relationships, but it remains unclear what motivates them to engage in social interactions at all. Their experience of social reward may provide an important clue. In Study 1 of this paper, a large sample of participants (N = 505) completed a measure of psychopathic traits (Self-Report Psychopathy Scale Short-Form) and a measure of social reward value (Social Reward Questionnaire) to explore what aspects of social reward are associated with psychopathic traits. In Study 2 (N = 110), the same measures were administered to a new group of participants along with two experimental tasks investigating monetary and social reward value. Psychopathic traits were found to be positively correlated with the enjoyment of callous treatment of others and negatively associated with the enjoyment of positive social interactions. This indicates a pattern of ‘inverted’ social reward in which being cruel is enjoyable and being kind is not. Interpersonal psychopathic traits were also positively associated with the difference between mean reaction times (RTs) in the monetary and social experimental reward tasks; individuals with high levels of these traits responded comparatively faster to social than monetary reward. We speculate that this may be because social approval/admiration has particular value for these individuals, who have a tendency to use and manipulate others. Together, these studies provide evidence that the self-serving and cruel social behaviour seen in psychopathy may in part be explained by what these individuals find rewarding.

Sexual sadism in sexual offenders and sexually motivated homicide

This article gives a clinically oriented overview of forensically relevant forms of sexual sadism disorder and its specific relationship to sexual homicide. In sexual homicide perpetrators, peculiar patterns of sexual sadism may be a motivational pathway to kill. Sexual sadism increases the risk for reoffending in sexual offenders. Through psychotherapy and pharmacological interventions, treatment of sadistic sex offenders has to consider special characteristics that may be different from those of nonsadistic sex offenders. Many of these offenders share a combination of sexual sadistic motives and an intact self-regulation, sometimes combined with a high level of sexual preoccupation.

Relating sexual sadism and psychopathy to one another, non-sexual violence, and sexual crime behaviors

Sexual sadism and psychopathy have been theoretically, clinically, and empirically linked to violence. Although both constructs are linked to predatory violence, few studies have sought to explore the covariation of the two constructs, and even fewer have sought to conceptualize the similarities of violence prediction in each. The current study considered all four Psychopathy Checklist-Revised (PCL-R) facets and employed well-defined, validated measures of sadism to elucidate the relation between sadism and psychopathy, as well as to determine the role of each in the prediction of non-sexual violence and sexual crime behaviors. Study 1 assessed 314 adult, male sex offenders using archival ratings, as well as the self-report Multidimensional Inventory of Development, Sex, and Aggression (the MIDSA). Study 2 used archival ratings to assess 599 adult, male sex offenders. Exploratory and confirmatory factor analyses of crime scene descriptions yielded four sexual crime behavior factors: Violence, Physical Control, Sexual Behavior, and Paraphilic. Sadism and psychopathy covaried, but were not coextensive; sadism correlated with Total PCL-R, Facet 1, and Facet 4 scores. The constructs predicted all non-sexual violence measures, but predicted different sexual crime behavior factors. The PCL-R facets collectively predicted the Violence and Paraphilic factors, whereas sadism only predicted the Violence factor.

Behavioral Confirmation of Everyday Sadism

Past research on socially aversive personalities has focused on subclinical psychopathy, subclinical narcissism, and Machiavellianism—the “Dark Triad” of personality. In the research reported here, we evaluated whether an everyday form of sadism should be added to that list. Acts of apparent cruelty were captured using two laboratory procedures, and we showed that such behavior could be predicted with two measures of sadistic personality. Study 1 featured a bug-killing paradigm. As expected, sadists volunteered to kill bugs at greater rates than did nonsadists. Study 2 examined willingness to harm an innocent victim. When aggression was easy, sadism and Dark Triad measures predicted unprovoked aggression. However, only sadists were willing to work for the opportunity to hurt an innocent person. In both studies, sadism emerged as an independent predictor of behavior reflecting an appetite for cruelty. Together, these findings support the construct validity of everyday sadism and its incorporation into a new “Dark Tetrad” of personality.

High-risk sexual offenders: an examination of sexual fantasy, sexual paraphilia, psychopathy, and offence characteristics

High-risk sexual offenders are a complex and heterogeneous group of offenders about whom researchers, clinicians, and law enforcement agencies still know relatively little. In response to the paucity of information that is specifically applicable to high-risk offenders, the present study investigated the potential influence of sexual fantasy, sexual paraphilia, and psychopathy on the offending behaviour of 139 of the highest risk sexual offenders in one province of Canada. The sample included 41 child molesters, 42 rapists, 18 rapist/molesters, 30 mixed offenders, and 6 "other" sexual offenders. Two offenders could not be categorized by type due to insufficient file information. Data analyses revealed significant differences between offender types for a number of criminal history variables including past sexual and nonsexual convictions, number of victims, weapon use, and age of offending onset. Further, there were significant differences between offender types for sexual fantasy themes, paraphilia diagnoses, and levels of psychopathy. For example, results revealed that offenders' sexual fantasies were significantly more likely to correspond with the specific type of index sexual offence that they had committed. Further, offenders scoring high in psychopathy were significantly more likely to have a sadistic paraphilia than offenders with either low or moderate psychopathy scores. Results from the current study provide a refined and informed understanding of sexual offending behaviour with important implications for future research, assessment, and treatment, as well as law enforcement practices when working with high-risk sexual offenders.

Emotional empathy and psychopathy in offenders: an experimental study

Previous studies associated psychopathy in adults with deficits in empathy but these studies did not directly compare cognitive and emotional facets of empathy. The present study sought to establish whether psychopathy is associated with impairments in emotional empathy among adult offenders. Participants were 90 male offenders scoring low (n = 29), medium (n = 33) or high (n = 28) on the Psychopathy Checklist-Revised (PCL-R) and n = 28 male noncriminal controls. Empathy functioning was assessed through self-report and computerized decision tasks, differentiating between perspective-taking (cognitive empathy) and compassion (emotional empathy). Against expectations, level of psychopathy among the offenders was not associated with either emotional or cognitive empathy. Offenders however had lower scores for both cognitive and emotional components of empathy functioning than controls. Both facets of empathy showed small but significant positive correlations with education level and social desirability. The methods employed to assess differences in empathy functioning may not be sensitive enough to assess differences in forensic samples.

Empathy in sexually sadistic offenders: an experimental comparison with non-sadistic sexual offenders

Previous studies suggest that severe sexual sadism and psychopathy are phenotypically different, although both are characterized by deficits in emotional processing. We assessed empathic capacity in a sample of 12 sexual sadists in comparison with 23 non-sadistic offenders using the Multifaceted Empathy Test (MET). All participants were forensic patients under mandatory treatment orders who had committed sexual offenses. The MET is a computerized rating task that differentiates and measures cognitive and emotional components of empathy, or perspective-taking versus compassionate components. To identify the effects of possible empathy deficits caused by psychopathic traits, we controlled both samples for psychopathy as a covariate, measured by the Psychopathy Checklist-Revised (PCL-R). According to our results, sexual sadists did not differ from non-sadistic sexual offenders with regard to emotional empathy for either positive or negative stimuli. The results suggest that severe sexual sadism is a distinct, pathological sexual arousal response, not a deficit in emotional processing.
