Neuroimaging and Brain-Based Markers Identifying Neurobiological Markers Associated With Criminal Behaviour, Personality Disorders, and Mental Health: A Narrative Review.

We begin the review by pointing to the common stigma associated with mental health issues, which often derives from a lack of understanding or incomplete knowledge. Neurobiological research provides us with a new lens to help challenge and dispel common assumptions and misunderstandings and gives an understanding of sexual behaviours that influence society. As such, it generates substantial evidence for the structural and functional asymmetry of the brains of individuals with mental disorders. However, this type of representation poses many challenges to traditional thinking and constantly provokes change in perspective and empathy towards those individuals. In the review, we go deeper into the effects of neurobiological findings on understanding criminal behaviours and personality disorders, looking further beyond behavioural health. These problems, which were once mainly discussed as moral ones or viewed from the perspective of character flaws, are analysed today through neurological considerations pointing to their complexity. When the root of bipolar disorder is revealed to be neurological, society will react with more information and understanding, hence reducing the stigmatisation and discrimination meted out to people with these problems. At a macro level, findings from neurobiology affect society in ways that go beyond individuals; social attitudes, laws, and policies about the services rendered are influenced. Operating as a catalyst within the community, neurobiological research helps to initiate social change through the creation of an informed, understanding public forum. Thus, it creates broader value for those dealing with behavioural and mental health challenges. The first and most important question of this narrative review is focused on identifying identifiable neurobiological markers that are closely related to criminal conduct, personality disorders, and mental health disorders. Through this review, we aim to present detailed insights into the neurological foundations that anchor these phenomena via a narrative analysis of contemporary literature. The potential implications are finding problems early to apply specific treatment and learning an advanced strategy for social attitudes. This will promote a more humanistic approach based on adequate information on the behavioural and mental health issues involved.

Examining the propensity and nature of criminal risk behaviours in frontotemporal dementia syndromes and Alzheimer's disease.

INTRODUCTION: Some people with dementia develop changes in behaviour and cognition that may lead to interactions with police or the legal system. However, large, prospective case-control studies examining these behaviours are lacking. METHODS: One hundred and forty-four people with dementia and 53 controls completed the Misdemeanours and Transgressions Screener. RESULTS: Criminal risk behaviours were reported in: 65.6% of behavioural-variant frontotemporal dementia, 46.2% of right-lateralised semantic dementia, and 27.0% of Alzheimer's disease patients. In 19.1% of patients these behaviours led to contact with police or authority figures. Compared to controls, people with dementia showed higher rates of physical assault (p = 0.024), financial/professional recklessness (p = 0.009), and inappropriate behaviours (p  = 0.052). DISCUSSION: Criminal risk behaviours are common across dementia subtypes and may be one of the first clinical signs of frontotemporal dementia. Further research to understand how to balance risk minimisation with an individual's liberties as well as the inappropriate criminalisation of people with dementia is needed. Highlights: The Misdemeanours and Transgressions Screener is a new tool to assess criminal risk behaviours.Forty-seven percent of patients with dementia show criminal risk behaviour after dementia onset.Behaviours included verbal abuse, traffic violations, physical assault.New onset of criminal risk behaviours >50 years is a clinical sign for frontotemporal dementia.

Mild traumatic brain injury increases engagement in criminal behaviour 10 years later: a case-control study.

Introduction: Sustaining a mild traumatic brain injury (mTBI) has been linked to increased criminal behaviour in later life. However, previous studies have not controlled for the number of injuries, gender, social deprivation, impact of past behaviour, or link to offence type. This study aims to determine if people who experienced a single or multiple mTBI have increased risk of criminal behaviour 10 years post-injury than matched orthopaedic controls. Methods: This was a case control study of adults (aged >16 years) who experienced a medically diagnosed mTBI and controls who experienced a lower limb fracture (with no TBI) over a 12-month period (01/01/2003-31/12/2003). Participants were identified within Stats New Zealand's Integrated Data Infrastructure (national database including health and justice records). Participants who experienced a subsequent TBI (post-2003), who were not resident in New Zealand, and who died by 2013 were excluded. Case and controls were matched by age, sex, ethnicity, deprivation index and pre-injury criminal history. Results: The study included N = 6,606 mTBI cases and N = 15,771 matched trauma controls. In the 10 years after injury, people experiencing a single mTBI had significantly higher numbers of violent charges (0.26 versus 0.21, p < 0.01) and violent convictions (0.16 versus 0.13, p < 0.05) but not for all court charges and convictions. Analysis of those with a history of prior mTBIs yielded larger effects, with significantly higher numbers of violent charges (0.57 versus 0.24, p < 0.05) and violent convictions (0.34 versus 0.14, p < 0.05). For males, the single mTBI case group had a significantly higher number of violent charges (0.40 versus 0.31, p < 0.05) and violent convictions (0.24 versus 0.20, p < 0.05) but this was not observed for females or all offence types. Discussion: Experiencing multiple mTBIs over the lifetime increases the number of subsequent violence-related charges and convictions but not for all offence types in males but not for females. These findings highlight the need for improved recognition and treatment of mTBI to prevent future engagement in antisocial behaviour.

["Impulsive insanity" according to Emil Kraepelin : A clinical framework for female criminals at the beginning of the twentieth century]. / Das "impulsive Irresein" nach Emil Kraepelin : Ein Krankheitsbild für die Verbrecherinnen am Beginn des 20. Jahrhunderts.

BACKGROUND: In his comprehensive classification of the beginning of the twentieth century, Emil Kraepelin provided a detailed description of an entity he called "impulsive insanity", which had not been elaborated before him. The forms depicted by him largely corresponded to the offences, which were referred to as typically female in their nature in the late nineteenth and early twentieth centuries. QUESTION: How did Kraepelin classify "impulsive insanity" and what forms did he describe? Did Kraepelin also see these disorders predominantly prevailing in women, did he establish a connection with women's criminality and how did this fit into the discourses of the time on femininity, criminal legislation and degeneration? MATERIAL AND METHODS: This study focused on the clinical picture "impulsive insanity" as described by Emil Kraepelin in his main work, the 8th edition of his Textbook of Psychiatry published between 1909 and 1915. His description was analyzed in detail and embedded in a historical context on the basis of secondary literature. RESULTS: In rudiments Kraepelin's clinical classification is still comprehensible today, although there are major differences to how literature in later years treated this issue. Kraepelin clearly sees "impulsive insanity" as a driving disorder predominantly prevailing in women. DISCUSSION: Elaborating his concept of "impulsive insanity", Kraepelin positioned himself in relation to important scientific discourses of the early twentieth century, such as the debate on criminal legislation and the theory of degeneration. On the basis of the individual forms of "impulsive insanity" described by Kraepelin, various concepts of constructing and pathologizing femininity can be identified. Apparently, it also aims to explain common female crimes within the patriarchal hegemony.

Gambling and crime: An exploration of gambling availability and culture in an English prison.

BACKGROUND: There is evidence that prisoners have the highest rate of problem gambling in any population, but little is known about the nature of in-prison gambling, the motives for it or how it relates to prior gambling behaviour. AIMS: To investigate the prevalence and type of gambling prior to prison and the prevalence, type, and reasons for gambling in prison. METHODS: Two hundred and eighty-two male volunteers in a Category B male prison in England completed a questionnaire which included the Problem Gambling Severity Index (PGSI). RESULTS: One hundred and twenty-six (45%) reported gambling in prison, with eighty-one (30%) of participants reporting that gambling was a normal part of prison life. Pre-prison behaviour, whether type of index offence or prior gambling, had little relationship to in-prison gambling. Frequency of gambling in prison increased with increasing PGSI risk category. The most common types of gambling in prison were card/dice games, sports and ball games, while the most common motives were entertainment, excitement or sense of challenge and to win prizes, with significant differences in motive between PGSI risk categories. Prison canteen items formed the most common currency gambled. People within the higher PGSI risk category were more likely to have borrowed items from other prisoners. CONCLUSIONS: Our research has added to existing literature by identifying high rates of gambling in prison and showing that prisoners' perceptions of gambling are as a normal part of prison life. Findings suggest that screening and support should be available to manage gambling in prison, including support to reduce gambling-related debt, particularly given associations between debt and violence in prison. Relief from boredom and need for excitement were among the most common reasons for gambling in prison, indicating that there is a need to provide a more appropriately stimulating prison environment.

Intergenerational continuity of crime: A comparison between children of discordant siblings.

BACKGROUND: Various studies have shown that fathers and children show similarities in criminal behaviour, but little is known about the nature of this relationship. By using a family-based research design, this study controls for familial confounders and gives a better estimate of the extent to which paternal crime has a direct effect on offspring offending. AIMS: To test the extent of any relationship between paternal offending during the childhood of offspring and adolescent offending by those offspring and to examine the effect of potential confounders of this relationship. METHODS: Data were from records held by Statistics Netherlands for 1,155,771 individuals born in the Netherlands between 1996 and 2001. Police data were used to measure paternal offending during the childhood (age 0-11) of this cohort and their adolescent offending (age 12-18). Logistic regression analyses were used to estimate the bivariate relationship between paternal and offspring offending, as well as this relationship after controlling for various demographic and socio-economic variables. Conditional logistic regression analyses were used to compare children of discordant brothers (N = 9232). By comparing within families rather than between unrelated individuals, all unmeasured familial factors that are shared between these cousins were controlled for. RESULTS: Offending during adolescence was about three times as likely among offspring whose fathers had offended while they were 11 years old or younger than among adolescents with no such paternal problem (OR: 3.21, CI 3.17-3.26). This relationship was attenuated after controlling for measured confounders (OR: 1.78, CI 1.75-1.81) and for unmeasured familial confounders (OR: 1.47, CI 1.36-1.59), but remained significant. CONCLUSIONS: Paternal offending has an association with offspring offending, but this is small after controlling for measured socio-economic and unmeasured familial confounders. Previous studies that did not control for unmeasured familial confounders seem likely to have overestimated the effect of paternal crime on their offspring's offending. This has implications for interventions for the offspring. If confined to mitigating the negative consequences of paternal offending, they are likely to have limited effectiveness.

Brief Report: Sentencing Outcomes for Offenders on the Autism Spectrum.

Although people diagnosed with autism spectrum disorder (ASD) are not more likely to commit crimes, they are overrepresented in the criminal justice system as reported by Howlin (Autism and Asperger syndrome: Preparing for adulthood, Routledge, 2004). This may, in part, be due to unfavourable interactions with the criminal judiciary. Evidence suggests the autistic population are perceived unfavourably in adjudicative proceedings resulting in harsher penalties. The present study explores whether ASD offenders (ASD-O) receive longer sentences compared to national sentencing data. Sentencing data from the Australian Bureau of Statistics (ABS) were used to compare ASD-O with similar offences. ASD-O attracted longer sentences across all offence classifications. Inferential analyses indicated sexual assault sentences were significantly higher in the ASD-O sample. No significant differences were found for murder, manslaughter, and assault.

Genetic Variants Allegedly Linked to Antisocial Behaviour Are Equally Distributed Across Different Populations.

Human behaviour is determined by a complex interaction of genetic and environmental factors. Several studies have demonstrated different associations between human behaviour and numerous genetic variants. In particular, allelic variants in SLC6A4, MAOA, DRD4, and DRD2 showed statistical associations with major depressive disorder, antisocial behaviour, schizophrenia, and bipolar disorder; BDNF polymorphic variants were associated with depressive, bipolar, and schizophrenia diseases, and TPH2 variants were found both in people with unipolar depression and in children with attention deficit-hyperactivity disorder (ADHD). Independent studies have failed to confirm polymorphic variants associated with criminal and aggressive behaviour. In the present study, a set of genetic variants involved in serotoninergic, dopaminergic, and neurobiological pathways were selected from those previously associated with criminal behaviour. The distribution of these genetic variants was compared across worldwide populations. While data on single polymorphic variants showed differential distribution across populations, these differences failed to be significant when a comprehensive analysis was conducted on the total number of published variants. The lack of reproducibility of the genetic association data published to date, the weakness of statistical associations, the heterogeneity of the phenotype, and the massive influence of the environment on human behaviour do not allow us to consider these genetic variants as undoubtedly associated with antisocial behaviour. Moreover, these data confirm the absence of ethnic predisposition to aggressive and criminal behaviour.

From Criminalized Patients to Risk-Exposed Agents: Reconceptualizing Carceral Involvement among Individuals with Psychiatric Diagnoses.

Individuals with serious mental disorder diagnoses (SMD) are overrepresented in U.S. jails and prisons, returning to custody more often and more quickly than those without these diagnoses. This paper examines the strengths and limitations of existing theoretical interpretations of justice involvement among those with SMD and presents results from in-depth interviews (n = 23) in an effort to direct an alternative theoretical path. Findings indicate people with SMD are not simply subject to the whims of their psychopathology, and instead are risk-exposed agents whose arrests are related to early institutionalization, interpersonal conflict, and life circumstances punctuated by socioeconomic marginality. Such findings suggest longitudinal and multi-level theoretical orientations are most appropriate for understanding carceral involvement among individuals with SMD.

Disengagement from mental health treatment and re-offending in those with psychosis: a multi-state model of linked data.

BACKGROUND AND AIMS: Individuals with psychosis are over-represented in the criminal justice system and, as a group, are at elevated risk of re-offending. Recent studies have observed an association between increased contacts with mental health services and reduced re-offending, as well as reduced risk of re-offending in those who are ordered to mental health treatment rather than punitive sanctions. In furthering this work, this study examines the effect of disengagement from mental health treatment on probability of re-offence in offenders with psychosis over time. METHODS: Data linkage was conducted with judicial, health and mortality datasets from New South Wales, Australia (2001-2015). The study population included 4960 offenders with psychosis who received non-custodial sentences and engaged with community-based mental health treatment. Risk factors for leaving treatment and/or reconviction were examined using multivariate cox regression. Further, a multi-state model was used to observe the probabilities associated with individuals moving between three states: conviction, disengagement from mental health treatment and subsequent re-conviction. RESULTS: A threefold increase was observed in the risk of re-offending for those who disengaged from treatment compared to those who did not (aHR = 2.76, 95% CI 1.65-4.62, p < 0.001). The median time until re-offence was 195 days, with the majority (67%) being convicted within one year of leaving treatment. A higher risk of leaving treatment was found for those born outside of Australia, with substance-related psychosis, and a history of violent offence. CONCLUSIONS: The findings argue for an emphasis on continued engagement with mental health services following release for offenders with psychosis and identify subgroups within this population for whom concentrated efforts regarding treatment retention should be targeted.

Explaining trajectories of adolescent drunkenness, drug use, and criminality: A latent transition analysis with socio-ecological covariates.

BACKGROUND: Although there are diverse trajectories in adolescent substance use and criminality, it is less clear why some adolescents follow one pathway and not another. In this study, we examine how different domains in a young person's life, such as temperament, peer, and family factors, are linked to different trajectories and whether some domains are more strongly associated with specific patterns of these behaviours. METHODS: Data comes from the Longitudinal Research on Development in Adolescence (LoRDIA) study in Sweden. Adolescents were surveyed at baseline (n = 755, age 13, grade 7) and followed up at grades 8 and 9. Latent transition analysis and multinomial logistic regression were conducted. RESULTS: Four distinct statuses were found, showing heterogeneity in adolescent substance use and criminal behaviours. These statuses were however highly stable. Individual, peer and family domains were all relevant in distinguishing between the statuses. A key finding is that the relative importance of these domains differed between statuses, suggesting differential effects of the domains on the different trajectories. The pre-teen family environment, as well as criminal peers, was most strongly associated with a more entrenched group. This was not the case for a 'Dabblers' group, where novelty-seeking was weakly linked. For the 'Occasional Law Breakers', criminal peers was more strongly associated. CONCLUSIONS: Our results suggest that substance use and criminality in early to mid-adolescence is more diverse than current theories allow. Moreover, the different trajectories in these behaviours are likely to have different causal mechanisms, which has important implications for theory, policy and practice.

Externalising pathways to alcohol-related problems in emerging adulthood.

BACKGROUND: Both 'early-onset persistent' and 'adolescent-onset' conduct problems (CPs) are associated with alcohol-related problems in emerging adulthood. The escalation of early CPs into criminal behaviour and heavy alcohol consumption prior to emerging adulthood are both likely to be important pathways. METHODS: Data were analysed from 3,038 young people in a UK birth cohort, the Avon Longitudinal Study of Parents and Children. The exposure was developmental trajectories of CPs ('low', 'childhood-limited', 'adolescent-onset' and 'early-onset persistent') between ages 4 and 13 years. The mediator was latent classes representing heavy alcohol consumption and/ or criminal behaviour at age 15 years. For the outcome, a quadratic latent growth curve was estimated to capture nonlinear change in alcohol-related problems between ages 18 and 23 years. RESULTS: Those with 'early-onset persistent' [b(95% CI) = 1.16 (0.17, 2.14)] and 'adolescent-onset' CPs [b(95% CI) = 1.31 (0.17, 2.45)] had higher levels of alcohol-related problems at age 18 years compared to those with 'low' CPs', but there was little evidence of an association with alcohol-related problems after age 19 years. There was evidence for an indirect effect of 'early-onset persistent' CPs [b(95% CI) = 1.12 (0.52, 1.72)] on alcohol-related problems at age 18 years via the latent classes of alcohol and criminal behaviour in adolescence. This was not found for 'adolescent-onset' CPs [b(95% CI) = 0.35 (-0.36, 1.07)]. CONCLUSIONS: Strong associations exist between early CPs, adolescent alcohol consumption and criminal behaviour and alcohol-related problems at age 18 years. Associations between early CPs and alcohol-related problems weakened considerably across emerging adulthood.

Problem gambling and support preferences among Finnish prisoners: a pilot study in an adult correctional population.

PURPOSE: The purpose of this paper is to explore the prevalence of potential problem gambling among Finnish prisoners; the associations between problem gambling and demographics, substance use and crime-related factors; and problem gamblers' support preferences. DESIGN/METHODOLOGY/APPROACH: Prisoners (n=96) from two Finnish prisons were recruited between December 2017 and January 2018. The estimated response rate was 31 percent. Gambling problems were measured using the Brief Biosocial Gambling Screen. The participants were asked to report their gambling both for one year prior to their incarceration and for the past year. The independent variables were demographics (age, gender and marital status), substance use (alcohol, smoking and narcotics) and crime-related factors (crime type, prison type and previous sentence). Statistical significance (p) was determined using Fischer's exact test. FINDINGS: Past-year pre-conviction problem gambling prevalence was 16.3 percent and past-year prevalence 15 percent. Age, gender, smoking, alcohol or illicit drug use were not associated with past-year problem gambling before sentencing. One-third of the prisoners (33.3 percent) who were sentenced for a property crime, financial crime or robbery were problem gamblers. One-quarter (24 percent) of all participants showed an interest in receiving support by identifying one or more support preferences. The most preferred type of support was group support in its all forms. RESEARCH LIMITATIONS/IMPLICATIONS: It is recommended that correctional institutions undertake systematic screening for potential problem gambling, and implement tailored intervention programs for inmates with gambling problems. ORIGINALITY/VALUE: This study provides a deeper understanding of problem gambling in prisons. Problem gambling is associated with crime and also seems to be linked with serving a previous sentence. Early detection and tailored interventions for problem gambling may help to reduce reoffending rates.

The Impact of Housing First on Criminal Justice Outcomes among Homeless People with Mental Illness: A Systematic Review.

OBJECTIVE: Housing First is increasingly put forward as an important component of a pragmatic plan to end homelessness. The literature evaluating the impact of Housing First on criminal justice involvement has not yet been systematically examined. The objective of this systematic review is to examine the impact of Housing First on criminal justice outcomes among homeless people with mental illness. METHOD: Five electronic databases (PsycINFO, MEDLINE, Embase, CINAHL, Web of Science) were searched up until July 2018 for randomised and nonrandomised studies of Housing First among homeless people with a serious mental disorder. RESULTS: Five studies were included for a total of 7128 participants. Two studies from a randomised controlled trial found no effect of Housing First on arrests compared to treatment as usual. Other studies compared Housing First to other programs or compared configurations of HF and found reductions in criminal justice involvement among Housing First participants. CONCLUSIONS: This systematic review suggests that Housing First, on average, has little impact on criminal justice involvement. Community services such as Housing First are potentially an important setting to put in place strategies to reduce criminal justice involvement. However, forensic mental health approaches such as risk assessment and management strategies and interventions may need to be integrated into existing services to better address potential underlying individual criminogenic risk factors. Further outcome assessment studies would be necessary.

Perfil del psicópata institucionalizado sin comportamiento criminal previo a su entrada en prisión / A profile of institutionalized psycopaths without a history of criminal behavior before incarceration

La inclusión en el PCL-R del comportamiento criminal previo como criterio para la evaluación de la psicopatía en las prisiones, supone que los individuos evaluados como psicópatas en la comunidad por sus consistencias de personalidad no sean detectados al llegar a prisión. Se pretende establecer el perfil diferencial del psicópata no detectado frente al psicópata criminal a nivel familiar, educativo, de consumo y delictivo. La muestra está conformada por 352 internos en prisión que fueron evaluados mediante el PCL-R. Los resultados obtenidos confirman que el psicópata no detectado presenta mismas consistencias de personalidad que el psicópata criminal, difiriendo en el estilo de vida; exhibe variables moderadoras durante su desarrollo que le han mantenido alejado del comportamiento criminal; no ha tenido un estilo de vida delictivo, pero mantiene la misma capacidad que el psicópata criminal para la comisión de los delitos más graves, siendo víctimas más frecuentes familiares y parejas.

The previous criminal behavior included in the PCL-R like a criterion to evaluation of the psychopathy in the prisons, suppose that individuals considered as psychopaths in the community for their personality were not detected when they arrive to prison. The aim of this research was to establish the different profile of the undetected psychopath in comparison with criminal psychopath in the familiar, educative, substance abuse and criminal environments. The sample was made up of 352 prisoners evaluated with the PCL-R. Results revealed that undetected psychopath showed the same personality but different lifestyle than criminal psychopath. Moreover, undetected psychopath accounted with moderating variables during his development that avoid them committing criminal behavior. Finally they did not show a criminal lifestyle, however, as the same as a criminal psychopath, they had the capacity to commit serious crimes being their victims their relatives or couples.

Exploring parents' understandings of their child's journey into offending behaviours: A narrative analysis.

Parents are perhaps the best placed individuals to comment upon their child's life story, including early life experiences, transitions and their child's needs. However, research has rarely focussed on the views of parents of young people who have committed serious offences. This research aimed to explore parents' opinions of which factors may have led to their child becoming involved with the criminal justice system. Interviews were undertaken with six parents who were asked to narrate their child's life journey into offending behaviours. The data were then analysed using narrative analysis techniques, and a shared story was created which incorporated the main transitional stages in the children's journeys, as seen by the parents. The findings suggest that it is not just the child but the whole family who have been in a state of distress throughout the child's life. Systemic and environmental factors are argued to contribute to this distress, and the use of diagnosis for this population is critically evaluated. The research highlights a life story in which the child's and family's distress remains unheard and therefore unresolved. Clinical implications for working with this population are discussed.

Rethinking responsibility in offenders with acquired paedophilia: punishment or treatment?

This article reviews the current neurobiological literature on the aetiology of developmental and acquired paedophilia and examines what the consequences could be in terms of responsibility and treatment for the latter. Addressing the question of responsibility and punishment of offenders with acquired paedophilia from a neurobiological perspective is controversial. Consequently it is essential to avoid hasty conclusions based strictly on neurobiological abnormality justifications. This study establishes a distinction between developmental and acquired paedophilia. The article investigates whether offenders who fulfil the diagnosis of acquired paedophilia should be held fully responsible, particularly in cases where the offender's conduct appears to result from volitionally controlled behaviour that is seemingly incompatible with a neurological cause. Moreover, the article explores how responsibility can be compromised when offenders with acquired paedophilia have (partially) preserved moral knowledge despite their sexual disorder. The article then examines the option of offering mandatory treatment as an alternative to imprisonment for offenders with acquired paedophilia. Furthermore, the article addresses the ethical issues related to offering any form of quasi-coercive treatment as a condition of release. This study concludes that decisions to fully or partially excuse an individual who fulfil the diagnosis of acquired paedophilia should take all relevant information into account, both neurobiological and other environmental evidence, and should proceed on a careful case by case analysis before sentencing or offering treatment.

Linking Psychological Traits With Criminal Behaviour: A Review

Objective: Apart from environmental and social factors, psychological traits is largely linked with criminal and delinquent behaviour. The purpose of this article is to review four critical psychological traits of individuals that may lead to criminal behaviour in a nutshell. Methods: An archival research methodology was employed in this study where relevant search for literatures on these four psychological traits was made across search engines such as Google Scholar with relevant articles selected for this review. The literatures were microscopically reviewed in order to demonstrate the linkage between psychological traits and criminal behaviour. Results: Four psychological traits: personality trait, low self-control, aggression behaviour, and cognitive distortion were chosen to address such linkages. All these four traits were discussed thoroughly in relation to crime and criminality contexts. Conclusion: It is crucial to understand the role of these traits and in-depth understanding of each psychological trait with relation of criminal behaviour offers and opportunity to the public at large to expand their knowledge on the importance of practicing and equipping oneself with healthy psychological traits to hinder criminal and delinquent acts.

The dangers of conditioning on the time of occurrence of one demographic process in the analysis of another.

In studies of the fertility of migrants in which the data are confined to the migrants only, estimation bias will normally appear in comparisons of childbearing before and after migration. The same issue arises in studies of union formation before and after first birth, marriage formation before and after home purchase, and in any other comparison of behaviour before and after an index event if one confines the study only to those who have experienced the index event. It is normally better to avoid analysis of behaviour before the index event because such analysis actually conditions on the later arrival of the index event. In this paper, we provide graphical and mathematical representations of this problem and show how one can get a meaningful (unconditional) comparison of behaviour before and after the index event provided the data contain enough information for both sub-periods. Otherwise, the analyst should refrain from making a comparison of this nature.

Judiciary views on criminal behaviour and intention of offenders with high-functioning autism.

PURPOSE: The purpose of this paper is to explore how judges perceive High Functioning Autistic Spectrum Disorders (hfASDs) and the disorders' effects on an offender's ability to formulate criminal intent and control behaviour. DESIGN/METHODOLOGY/APPROACH: Semi-structured interviews on topics related to offenders with hfASDs were conducted with 21 California Superior Court Judges. A coding scheme was developed and an iterative qualitative coding process was used for analysis. FINDINGS: Analysis yielded three major themes on how an hfASD diagnosis affects an offender's ability to regulate actions and criminal behaviour. Interviewed judges reported beliefs that hfASD offenders view the world in a different way and that much of their behaviour is not under their direct control. Judges reported these perceptions likely affect how they criminally process and make legal decisions regarding offenders with hfASDs. RESEARCH LIMITATIONS/IMPLICATIONS: The sample size was small and therefore no statistical significance can be drawn from results; findings cannot be applied to perceptions or experiences of the entire California Superior Court Judge population. ORIGINALITY/VALUE: Past academic research reports that individuals with hfASDs that offend often do so because of specific symptoms associated with the disorder. This presents a complex dilemma for the criminal justice system regarding how best to understand the disorder and process these offenders. This study and its findings aim to shed light on issues judges encounter in determining these offenders' responsibility and sentencing, in what ways this information might be integrated into judicial decision making, and areas where future research is needed.
