    A comparison of offenders with intellectual disability across three levels of security

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2006
    Todd Hogue
    Background,A number of authors have described, with disparate results, the prevalence of people with intellectual disability and their characteristics, in a range of offender cohorts defined by service use. These have included high security, a range of criminal justice services and community services. There is a need for research comparing cohorts of offenders with intellectual disabilities across different settings. Aim and hypothesis,To conduct such a comparison and test the hypothesis that severity of characteristics measured will be highest in highest levels of residential security. Method,A clinical-record-based comparison a offenders with intellectual disability in high security (n = 73), medium/low security (n = 70), and a community service (n = 69). Results,Groups were similar in age and tested IQ levels. Early psychiatric service contact had been more likely in the lower security groups. In line with the hypothesis, more complex presentations, in particular comorbid personality disorder, was more likely in the highest security group. Both fatal and non-fatal interpersonal violence convictions were significantly related to group, with more in the high security group sustaining a conviction both at the index offence and prior to that. Over 50% of all groups had at least one conviction for a sexual offence. A regression model accounting for 78% of the variance was made up largely of disposal variables (Mental Health Act status and probation) and indications of antisocial traits (criminal damage, lifetime conviction for murder and ICD-10 personality disorder classification). Conclusions and implications for practice,The authors show that context of sampling affects most relationships between intellectual disability (ID) and offending when the methods for measuring ID are held constant. The results also present several questions on the relationship between risk, services available in an area and referral to higher security. Copyright © 2006 John Wiley & Sons, Ltd. [source]

    Children, admitted to high security (special) hospital

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2003
    Adolescent Forensic Psychiatry, Claire Dimond Consultant in Child
    Introduction The Special Hospitals in England provide psychiatric treatment in high security. The aim of this study was to examine the demographics and background characteristics of children admitted to high security hospitals in England, using the special hospital case register. Method Forty-six children (the subject group) were admitted to a high security hospital under the MHA (1983) classification of disorder of mental illness and/or psychopathic disorder between 1983 and 1999, 33 (72%) of whom were male. A comparison group of adults was matched on sex, legal classification of detention and MHA 1983 classification of disorder. Results The children were admitted for a similar range of offences to those of the comparison group. However, the children had received convictions for criminal damage and violence at a significantly earlier age, they were more likely to have experienced a change in carer during their childhood, been placed in a children's home and were less likely to be living with a family member on their 16th birthday. Children admitted to special hospital experience a lot of disruption in their childhood and are extremely high users of multi-agency services as they grow up. Discussion Issues are raised regarding how to provide a developmentally sensitive service for children who require high security care. Copyright © 2003 Whurr Publishers Ltd. [source]

    The voice of detainees in a high security setting on services for people with personality disorder

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2002
    Sue Ryan
    Background British government Home and Health Departments have been consulting widely about service development for people with ,dangerous severe personality disorder' (DSPD). There has, however, been no consultation with service users, nor is there any user view literature in this area. Methods All people detained in one high security hospital under the legal classification of psychopathic disorder were eligible but those on the admission or intensive care wards were not approached. Views of service were elicited using a purpose designed semi-structured interview. The principal researcher was independent of all clinical teams. Confidentiality about patients' views was assured. Aims To establish views on services from one subgroup of people nominated by the government department as having ,DSPD'. Results Sixty-one of 89 agreed to interview. With security a given, about half expressed a preference for a high security hospital setting, 20% prison and 25% elsewhere, generally medium secure hospitals. Participants most valued caring, understanding and ,experience' among staff. An ideal service was considered to be one within small, domestic living units, providing group and individual therapies. Some found living with people with mental illness difficult, but some specified not wanting segregated units. Views were affected by gender and comorbidity. Conclusions As the sample were all in hospital, the emphasis on treatment may reflect a placement bias. All but five participants, however, had had experience of both health and criminal justice services, so were well placed to talk with authority about preferences.

    A digital secure image communication scheme based on the chaotic Chebyshev map

    INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 5 2004
    Xiaofeng Liao
    Abstract In this paper, a simple image secure communication scheme based on the chaotic Chebyshev map and chaos synchronization is proposed. The scheme relies on the excellent correlation property of chaotic sequences, which is very desirable for secure image communication. The results obtained by computer simulation indicate that the transmitted source image can be correctly and reliably recovered using the proposed scheme, even through a noisy channel. Notably, the scheme possesses relatively high security and can be easily implemented. Moreover, the quality of the recovered image is satisfactory, quantified by such common criteria as the bit-error rate performance. Copyright © 2004 John Wiley & Sons, Ltd. [source]

    Presentations of psychosis with violence: variations in different jurisdictions.

    BEHAVIORAL SCIENCES & THE LAW, Issue 5 2008
    A comparison of patients with psychosis in the high security hospitals of Scotland, England
    Background International literature is consistent on there being a significant relationship between psychosis and violence, less so on its extent and nature, but two main presentational types are increasingly recognized. In one, people are unremarkable before onset of illness and psychotic symptoms commonly drive violence; in the other, psychosis is preceded by childhood conduct problems, associated with personality disorder, and psychotic symptoms seem less relevant. Aims To explore the extent to which variations in aspects of social and service context in different jurisdictions affect presentational type among people admitted to high security hospitals. Hypotheses There will be differences between jurisdictions in proportions of patients with pure psychosis or with psychosis and antecedent personality disorder, but symptom drive to violence will be more common in the pure psychosis group regardless of social, legal and service context. Method Independently conducted record studies were used to compare high security hospital patients with psychosis in Scotland and England, all resident between 25 August 1992 and 13 August 1993. Results The cohorts were similar in offence histories, predominance of schizophrenia, age at first hospitalization for psychosis and first high security hospitalization. More Scottish patients had co-morbid substance misuse diagnoses and/or personality disorder than patients in England. Psychotic symptom drive to the index offence was, however, four times more likely in the pure psychosis groups, regardless of sex, ethnic group or country. Scottish patients spent less time in high security after the index act. Conclusions Our hypotheses were sustained. Knowledge about lifestyle before onset of psychosis is important for interpreting literature on how psychotic symptoms relate to violence. This may also influence longer term outcome, although the shorter length of secure hospital stay in Scotland was perhaps affected more by greater availability of open ,step-down' beds.
