Addiction disorders, psychopathy and crime in the light of empirical studies results

The paper is based on the available empirical researches and examines the scientific basis of widely accepted thesis about the connection of substance addiction, psychopathy and crime. The analysis of research results indicated that correlation between the observed phenomena exists not only at a symptomatic level, but also at the level of etiology. It was established that the same risk factors underly alcoholism, drug addiction, psychopathy and criminal behavior. It was also found that the presence of conduct disorders at an early age (before the age of 15) indicates that psychopathic disorder is primary and that in this case, psychopathy is a reliable predictor of addiction and penal treatment failure, and also that it contributes substantially to addictive and criminal recidivism. Highly aggressive and poorly controlled psychopaths under the desinhibited influence of substances become even more violent and dangerous and most of them have a polysubstance disorder. Therefore, for the prevention of all three maladaptive forms, particularly important is the category of minors with early disruptive behavior, characterized by lower verbal ability, increased impulsivity and high aggressiveness as a main feature of psychopathy. Judging by research findings, the absence of conduct disorders in juvenile period could be considered as an indicator that psychopathic and criminal behavior occur as a secondary effect of substance abuse, with better chances for rehabilitation.

High levels of psychopathic traits alters moral choice but not moral judgment

Psychopathy is a personality disorder frequently associated with immoral behaviors. Previous behavioral studies on the influence of psychopathy on moral decision have yielded contradictory results, possibly because they focused either on judgment (abstract evaluation) or on choice of hypothetical action, two processes that may rely on different mechanisms. In this study, we explored the influence of the level of psychopathic traits on judgment and choice of hypothetical action during moral dilemma evaluation. A population of 102 students completed a questionnaire with ten moral dilemmas and nine non-moral dilemmas. The task included questions targeting both judgment (“Is it acceptable to … in order to …?”) and choice of hypothetical action (“Would you … in order to …?”). The level of psychopathic traits of each participant was evaluated with the Levenson Self-Report Psychopathy (LSRP) scale. Logistic regression fitted with the generalized estimating equations method analyses were conducted using responses to the judgment and choice tasks as the dependent variables and psychopathy scores as predictor. Results show that a high level of psychopathic traits, and more specifically those related to affective deficit, predicted a greater proportion of utilitarian responses for the choice but not for the judgment question. There was no first-order interaction between the level of psychopathic traits and other potential predictors. The relation between a high level of psychopathic traits and increased utilitarianism in choice of action but not in moral judgment may explain the contradictory results of previous studies where these two processes were not contrasted. It also gives further support to the hypothesis that choice of action endorsement and abstract judgment during moral dilemma evaluation are partially distinct neural and psychological processes. We propose that this distinction should be better taken into account in the evaluation of psychopathic behaviors.

The Psychopath in the C Suite: Redifining the SOB

Meet the SOB — Seductive Operational Bully — or psychopath “lite.” SOBs don’t usually end up in jail or psychiatric hospital but they do thrive in an organizational setting. SOBs can be found wherever power, status, or money is at stake. Outwardly normal, apparently successful and charming, their inner lack of empathy, shame, guilt, or remorse, has serious interpersonal repercussions, and can destroy organizations. Their great adaptive qualities mean they often reach top executive positions, especially in organizations that appreciate impression management, corporate gamesmanship, risk taking, coolness under pressure, domination, competitiveness, and assertiveness. The ease with which SOBs rise to the top raises the question whether the design of some organizations makes them a natural home for psychopathic individuals. This article begins with an elaborate example of such an individual, and notes the deep divide that distinguishes people without a conscience from the general population. Most studies have resorted to a deficit theory to explain psychopathic behavior — something has gone with the wiring in the emotional part of the brain. Here, however, I suggest that nurture can also play a role in the etiology of psychopathy. The article explores ways of identifying and dealing with SOBs from an organizational and individual perspective, and recommends a clinical orientation to organizational diagnosis and intervention.

The relative influence of conduct problems and attention-deficit hyperactivity disorder in the development of adolescent psychopathy

Abstract An in depth literature review was conducted into the relative influence of conduct problems and attention-deficit hyperactivity disorder in the development of child/adolescent psychopathy. Lynam (1996) wrote that children/adolescents exhibiting behaviors of both were ‘fledgling psychopaths;’ however, recent evidence suggests that if youth with comorbid conduct problems and ADHD exhibit a persistent form of antisocial and/or psychopathic behavior, the cause is primarily due to the levels of conduct problems, not the influence of ADHD. This article looks at the three perspectives regarding the development of psychopathy: (1) Conduct Problem Mediation, (2) the Independent Position, and (3) the Comorbid Subtype. The studies examining the three perspectives found that the Conduct Problem Mediation, not the Comorbid Subtype, was the most important in the development of psychopathy.

Genetic and neurocognitive contributions to the development of psychopathy

An overview is provided of recent twin, molecular genetic, and magnetic resonance imaging studies that are helping to inform a model of developmental vulnerability to adult psychopathy. Although the current evidence base suggests that children with high levels of callous-unemotional traits are genetically and neurocognitively vulnerable to developing psychopathic and antisocial behaviors, existing research also clearly indicates that environmental influences play an important role. One potential implication is that interventions for children with antisocial behavior and callous-unemotional traits may need to be tailored to take into account their distinct pattern of neurocognitive vulnerability, as revealed by developmental neuroimaging studies. Specifically, interventions that pursue punishment-oriented or explicit empathy induction strategies may be less effective with this group of antisocial children. By contrast, preliminary evidence suggests that enhancing positive parenting and parental involvement, as well as applying consistent rewards may represent more promising intervention approaches.

ECP02-01 - Is forensic psychiatry erally needed in the training of modern psychiatrists

More than other disciplines in medicine psychiatry is closely connected with legal and medico-legal issues. Mental disorders can influence the individual capacities of cognition and affectivity which are necessary to comply with social norms and rules. Disturbances of impulse control, affect regulation and reality control may lead our patients to aggressive, disruptive, or disorganized behaviours which result in different forms of conflicts with the law. The psychiatrist must be able to detect the influence of disturbed mental functioning in offenders and to protect his patients against the usual consequences in society for deviant and criminal behaviour. Mentally ill offenders need treatment, not punishment. This is the reason that we need a well developped subdiscipline of forensic psychiatry. Important tasks are the evaluation of legal responsibility, the treatment and rehabilitation, last not least the prognosis of dangerousness. In addition, forensic psychiatry is based on detailed and differentiated analysis of abnormal mental conditions including psychopathic behaviours. Therefore, this subdiscipline is a resort for general and for clinical psychopathology, which have lost some of their importance in other fields of psychiatry

Breakdown in the brain network subserving moral judgment in criminal psychopathy

Neuroimaging research has demonstrated the involvement of a well-defined brain network in the mediation of moral judgment in normal population, and has suggested the inappropriate network use in criminal psychopathy. We used functional magnetic resonance imaging (fMRI) to prove that alterations in the brain network subserving moral judgment in criminal psychopaths are not limited to the inadequate network use during moral judgment, but that a primary network breakdown would exist with dysfunctional alterations outside moral dilemma situations. A total of 22 criminal psychopathic men and 22 control subjects were assessed and fMRI maps were generated to identify (i) brain response to moral dilemmas, (ii) task-induced deactivation of the network during a conventional cognitive task and (iii) the strength of functional connectivity within the network during resting-state. The obtained functional brain maps indeed confirmed that the network subserving moral judgment is underactive in psychopathic individuals during moral dilemma situations, but the data also provided evidence of a baseline network alteration outside moral contexts with a functional disconnection between emotional and cognitive elements that jointly construct moral judgment. The finding may have significant social implications if considering psychopathic behavior to be a result of a primary breakdown in basic brain systems.

Patterns and changes in psychopathic interpersonal behaviour in forensic inpatient treatment

ABSTRACTPsychopathy is a vital construct in the treatment of mentally disordered offenders, and it is arguable that at the heart of psychopathy is a deviant interpersonal style. The present study analysed the changes in perceived dominance and warmth (as rated by staff using the Chart of Interpersonal Reactions in Closed Living Environments) of 34 male psychopathic patients admitted to the Dangerous and Severe Personality Disorder Service of a high‐security hospital in the UK. Results showed that the level and direction of change in dominance and warmth were dependent on the level of psychopathy; patients with a higher level of psychopathy increased significantly in dominance but did not decrease in warmth, whereas patients with a lower level of psychopathy decreased significantly in warmth but did not increase in dominance. These results are discussed in terms of possible implications for the treatment and management of patients with varying levels of psychopathy. Copyright © 2011 John Wiley & Sons, Ltd.

Utilitarian moral judgment in psychopathy.

Psychopathic behavior is characteristically amoral, but to date research studies have largely failed to identify any systematic differences in moral judgment capability between psychopaths and non-psychopaths. In this study, we investigate whether significant differences in moral judgment emerge when taking into account the phenotypic heterogeneity of the disorder through a well-validated distinction between psychopathic subtypes. Three groups of incarcerated participants [low-anxious psychopaths (n = 12), high-anxious psychopaths (n = 12) and non-psychopaths (n = 24)] completed a moral judgment test involving hypothetical dilemmas. The moral dilemmas featured 'personal' (i.e. involving direct physical harm) or 'impersonal' (i.e. involving indirect or remote harm) actions. Compared to non-psychopaths, both groups of psychopaths were significantly more likely to endorse the impersonal actions. However, only the low-anxious psychopaths were significantly more likely to endorse the personal harms when commission of the harm would maximize aggregate welfare-the 'utilitarian' choice. High-anxious psychopaths and non-psychopaths did not significantly differ in their personal moral judgments. These results provide novel laboratory evidence of abnormal moral judgment in psychopaths, as well as additional support for the importance of considering psychopathic subtypes.

The notion of ‘the criminal gene’ is now dead and buried. Yet there is growing evidence that some psychopathic behaviour is indeed grounded in our genes and has an evolutionary origin

An exploratory study of the relations between psychopathic traits and depressive symptoms in a non-clinical sample of adolescents

Empirical evidence suggests an association between psychopathic traits, depressive symptoms and delinquent behavior in community samples of adolescents. In this study, a sample of 243 high school students completed questionnaires assessing depressive symptoms and psychopathic traits (callousness and narcissistic traits). There were significant positive correlations between depressive symptoms, callousness and narcissistic traits. Narcissistic traits appeared to be a mediator between depressive mood and callousness while depressive mood was the main predictor of impulsivity/poor behavioral control. These findings are consistent with the hypothesis that impulsivity/poor behavioral control, callous and narcissistic traits are defenses against depressed mood. Narcissistic defenses may prepare the development of callousness. There might be a developmental process from depressive symptoms to psychopathic traits and behavior problems in adolescents.

Attention Moderates the Fearlessness of Psychopathic Offenders

Psychopathic behavior is generally attributed to a fundamental, amygdala-mediated deficit in fearlessness that undermines social conformity. An alternative view is that psychopathy involves an attention-related deficit that undermines the processing of peripheral information, including fear stimuli. We evaluated these alternative hypotheses by measuring fear-potentiated startle (FPS) in a group of 125 prisoners under experimental conditions that 1) focused attention directly on fear-relevant information or 2) established an alternative attentional focus. Psychopathy was assessed using Hare's Psychopathy Checklist-Revised (PCL-R). Psychopathic individuals displayed normal FPS under threat-focused conditions but manifested a significant deficit in FPS under alternative-focus conditions. Moreover, these findings were essentially unchanged when analyses employed the interpersonal/affective factor of the PCL-R instead of PCL-R total scores. The results provide unprecedented evidence that higher-order cognitive processes moderate the fear deficits of psychopathic individuals. These findings suggest that psychopaths' diminished reactivity to fear stimuli, and emotion-related cues more generally, reflect idiosyncrasies in attention that limit their processing of peripheral information. Although psychopathic individuals are commonly described as cold-blooded predators who are unmotivated to change, the attentional dysfunction identified in this study supports an alternative interpretation of their chronic disinhibition and insensitive interpersonal style.

Attention moderates the processing of inhibitory information in primary psychopathy.

Primary psychopathic individuals are less apt to reevaluate or change their behavior in response to stimuli outside of their current focus of attention. According to the response modulation hypothesis, this tendency reflects a lack of responsivity to important peripheral information and undermines adaptive self-regulation. To evaluate this hypothesis, the authors administered a response competition (flanker-type) task and manipulated focus of visual attention. They predicted that psychopathic individuals would display significantly less interference to response incongruent information than nonpsychopathic participants when attention was cued to the target location but display normal interference when there was no prepotent focus of attention. The results confirmed this hypothesis and are consistent with the contention that attention moderates psychopathic individuals' responsivity to inhibitory cues. Implications of this attentional anomaly for psychopathic traits and behavior are discussed.

From Genes to Brain to Antisocial Behavior

This review summarizes recent brain-imaging and molecular-genetic findings on antisocial, violent, and psychopathic behavior. A “genes to brain to antisocial behavior” model hypothesizes that specific genes result in structural and functional brain alterations that, in turn, predispose to antisocial behavior. For instance, a common polymorphism in the monoamine oxidase A ( MAOA) gene has been associated with both antisocial behavior and also reductions in the volume of the amygdala and orbitofrontal (ventral prefrontal) cortex—brain structures that are found to be compromised in antisocial individuals. Here I highlight key brain regions implicated in antisocial behavior, with an emphasis on the prefrontal cortex, along with ways these areas give expression to risk factors for antisocial behavior. Environmental influences may alter gene expression to trigger the cascade of events that translate genes into antisocial behavior. Neuroethical considerations include how responsibility and punishment should be determined given the hypothesis that neural circuits underlying morality are compromised in antisocial individuals.

Measuring psychopathic traits in children through self-report. The development of the Youth Psychopathic traits Inventory—Child Version

The current article investigates whether self-reports of children provide reliable and valid information concerning psychopathic personality traits and behaviours. For this purpose, we developed a downward extension of an existing adolescent self-report measure; the Youth Psychopathic traits Inventory [YPI; Andershed, H., Kerr, M., Stattin, H., & Levander, S. (2002). Psychopathic traits in non-referred youths: Initial test of a new assessment tool. In E.S. Blaauw, L. (Ed.), Psychopaths: Current international perspectives (pp. 131–158): The Hague: Elsevier], called the Youth Psychopathic traits Inventory—Child Version (YPI-CV). The reliability and validity of the YPI-CV were tested in n = 360 children from the general population. The YPI-CV had good internal consistency and a three factor structure similar to the original adolescent version. Test–retest reliability over a 6-month period was adequate. In validating the instrument, both self, teacher and peer report were used. The convergent and divergent validity of the three YPI-CV dimensions was examined by relating each of them to an external criterion measures assessing the same construct. It was concluded that psychopathic traits can be measured reliably and meaningfully through self-report in 9 to 12 year olds and that the YPI-CV is potentially a useful instrument for doing so.

The limited role of neuroimaging in determining criminal liability: An overview and case report

Objective Studies indicate there is a substantial biological substrate for psychopathic behavior. Neuroimaging techniques have afforded biomedical sciences a means to investigate further how aberrant brain activity or structure may be correlated with psychopathy and violence. This paper will provide an overview of the literature, and then will explore the role of structural and functional MRI brain imaging in the defense of a young adult male charged with kidnapping and rape. Method Using Pubmed and the keywords “functional neuroimaging,” “structural neuroimaging,” “psychopathy,” “antisocial personality,” “sociopathy,” “aggression,” “impulsivity,” and “violence,” the authors conduct a review of structural and functional neuroimaging studies involving aggressive, violent, psychopathic or antisocial offenders. We then provide a case report of a defendant, charged with kidnapping and rape, who was found during a forensic evaluation to have abnormal neuroimaging findings. Results The defendant's counsel was able to present in his client's defense multiple indicators of brain dysfunction and psychiatric illness partially substantiated by brain imaging. Conclusions The extent to which neuroimaging findings can be used as exculpatory or mitigating evidence remains the subject of much debate. Neuroimaging is just one piece of evidence the forensic expert relies on in determining the extent of neuropathology and mental illness. As illustrated in the case report, imaging studies most often will serve a mitigating role, affording the courts an opportunity to tailor punishment, provide court-ordered treatment, and potentially decrease recidivism.

Personality Correlates of Physiological Response to Stress Among Incarcerated Juveniles

To examine the relationship between personality type and physiological response to stress among juvenile delinquents. Delinquent males (N = 42, mean age 16.5, SD = 1) recruited from a convenience sample at local juvenile detention facility were compared to a male control sample from a local high school (N = 79; mean age 16.1, SD = 0.8). All participants completed the Weinberger Adjustment Inventory and a Stress-Inducing Speech Task during both of which heart rate was measured. Compared to controls, delinquent youths showed significantly lower heart rates under both free association and stress conditions (p < 0.05) and a lower rate of increase during stressful stimuli (p < 0.05). Among delinquents, those with a non-reactive personality type appeared to show consistently lower levels of physiological arousal as measured by heart rate. Delinquents consistently had lower overall levels of arousal as measured by heart rate. In delinquent boys, we also found a persistently low arousal group with a non-reactive psychological pattern. This combination may be a forerunner of future psychopathy or a product of the developmental trajectory that leads to and results from psychopathic behavior.
