![]() ![]() The forthcoming ICD-11 classification should help in this endeavour. There is also a need for the development of effective treatment and interventions for those with established severe personality disorder and better identification of this level of disorder by psychiatrists. Severe personality disorder is highly prevalent among perpetrators of homicide, and the finding that it is more prevalent when strangers are the victims stresses both the need for early identification of those at risk of developing severe personality disorder and the development of appropriate early preventive interventions. Severe personality disorder was present in 62% (n = 338) of all those with a personality disorder and was significantly associated with homicides of strangers and previous violence. The prevalence of personality disorder using the PAS-DOC was 56.3% (95% confidence interval 52.3%, 60.3%), compared with 16% as diagnosed in reports. Factors associated with the diagnosis of severe personality disorder were examined. The prevalence of personality disorder and severe personality disorder was estimated. #Personality clusters seriesSix hundred court reports from a national case series of homicide perpetrators in England and Wales were analysed using a document-derived version of the Personality Assessment Schedule (PAS-DOC), providing categorical and dimensional personality assessments. ![]() Associations between severe personality disorder and sociodemographic, historical and offence-related characteristics were then explored. The aims were to estimate the prevalence of personality disorder in homicide perpetrators from court reports and carry out a dimensional assessment in keeping with the new ICD-11 classification of the prevalence of severe personality disorder. Psychoticism and Neuroticism mean scores were higher for the 'Case' groups than those for the 'Control' group thus establishing the effect of parental mental health on adolescents' personalityĬurrent UK evidence on the prevalence of personality disorder in homicide is lacking. Also, the proposed two-layer model established the effect of gender at 10% level of signicance in case of 'Control' group. ![]() Conclusion: In this study either through the conventional three-layer model or the proposed two-layer models, we concluded that some information about one dimension can be extracted from the other dimension with EPQ even if the correlation is not signicant. The variability of Neuroticism was estimated up to 63.6% by a linear combination of Psychoticism, Lie-scale and Gender in Layer 1 of the model for the 'Control' group. The two-layered model yielded no signicant difference between the base and the proposed model for 'Control' and 'Case' group as p-values were more than 0.05. Results: The conventional three-layer model for 'Control' group estimated 'Psychoticism' directly by 'Lie-scale' and indirectly by 'Extraversion' with p-values < 0.05. Methods: Structural equation models with two and three layers were applied to estimate personality traits as identied by Eysenck personality questionnaire on two groups of adolescents: (i) The 'Control' group whose parents were not reported any psychiatric disorder and (ii) the 'Case' group whose parent(s) were suffering from some psychiatric disorder as diagnosed by DSM-IV. Eysenck personality questionnaire is a psychiatric tool to assess various dimensions of personality. Lack of a support system may result in some psychiatric disorders among adolescents which might needs to be addressed. Afavourable atmosphere at home and surroundings play a pivotal role in development in different dimensions of personality. Introduction: Adolescence is a transformational but vulnerable age.Personality starts taking shape at this age and the traits developed during this phase are likely to remain with a person for the whole life. ![]()
