Autism spectrum disorder, attention-deficit hyperactivity disorder and offending

Identification and support of autistic individuals within the UK Criminal Justice System: a practical approach based upon professional consensus with input from lived experience

BACKGROUND

Autism spectrum disorder (hereafter referred to as autism) is characterised by difficulties with (i) social communication, social interaction, and (ii) restricted and repetitive interests and behaviours. Estimates of autism prevalence within the criminal justice system (CJS) vary considerably, but there is evidence to suggest that the condition can be missed or misidentified within this population. Autism has implications for an individual's journey through the CJS, from police questioning and engagement in court proceedings through to risk assessment, formulation, therapeutic approaches, engagement with support services, and long-term social and legal outcomes.

METHODS

This consensus based on professional opinion with input from lived experience aims to provide general principles for consideration by United Kingdom (UK) CJS personnel when working with autistic individuals, focusing on autistic offenders and those suspected of offences. Principles may be transferable to countries beyond the UK. Multidisciplinary professionals and two service users were approached for their input to address the effective identification and support strategies for autistic individuals within the CJS.

RESULTS

The authors provide a consensus statement including recommendations on the general principles of effective identification, and support strategies for autistic individuals across different levels of the CJS.

CONCLUSION

Greater attention needs to be given to this population as they navigate the CJS.

Prisoners with Attention Deficit Hyperactivity Disorder: co-morbidities and service pathways

PURPOSE

This paper aims to examine effective diagnostic and treatment pathways for attention deficit hyperactivity disorder (ADHD) in prison settings given the high prevalence of ADHD and comorbidities in the prison population.

DESIGN/METHODOLOGY/APPROACH

Two studies were carried out in two separate prisons in London. Firstly, data were collected to understand the prevalence of ADHD and the comorbidities. The second study used quality improvement (QI) methodology to assess the impact of a diagnostic and treatment pathway for prisoners with ADHD.

FINDINGS

Of the prisoners, 22.5% met the diagnostic criteria for ADHD. Nearly half of them were screened positive for autistic traits, with a higher prevalence of mental disorders among prisoners with ADHD compared to those without. The QI project led to a significant increase in the number of prisoners identified as requiring ADHD assessment but a modest increase in the number of prisoners diagnosed or treated for ADHD.

ORIGINALITY/VALUE

Despite various challenges, an ADHD diagnostic and treatment pathway was set up in a prison using adapted QI methodology. Further research is needed to explore the feasibility of routine screening for ADHD in prison and examine at a national level the effectiveness of current ADHD prison pathways.

Self-harm and Mental Health Characteristics of Prisoners with elevated rates of autistic traits

BACKGROUND

Prevalence studies among prisoners have found rates of 1-4% for autism spectrum disorder (ASD) or autistic traits. However, little is known about those prisoners with high levels of autistic traits.

AIM

This aim of this study was to compare the mental health characteristics of prisoners with autistic traits with neurotypical prisoners not screening positive for neurodevelopmental disorders.

METHOD

The study recruited 240 male prisoners from a London prison and screened for autism spectrum disorder using the Autism Quotient (AQ) 20 and 10, and Autism Diagnostic Observation Schedule (ADOS). The Mini International Neuropsychiatric Interview was used to assess for depression, anxiety, self-harm behavior and suicide.

RESULTS

Screening using the AQ identified 46 prisoners with significant autistic traits, with 12 meeting the diagnostic threshold for ASD using the ADOS. Those screening positive with autistic traits were significantly more likely to have thought about self-harm and suicide in the past month than neurotypical prisoners and have a comorbid mental disorder. They were also significantly more likely to report having attempted suicide during their lifetime compared to neurotypical peers at a rate of 64.9 % compared to 11.6 % for the neurotypical prisoners.

CONCLUSION

Prisoners with elevated levels of autistic traits were more likely to report self-harm, suicidal thoughts and were more vulnerable to a range of mental disorders than neurotypical prisoners. There is a need for more evidence on the experience of autistic prisoners to inform how pathways should work to improve health outcomes through increased awareness and access to screening and subsequent diagnosis which currently prisons are currently not set up for.

Autistic spectrum disorder and offending behaviour – a brief review of the literature

Purpose

The purpose of this paper to synthesise much of the existing research on autistic spectrum disorder (ASD) and offending behaviour.

Design/methodology/approach

It considers three key areas, namely, first, a discussion about the nature of ASD and how it might be related to offending behaviour; second, a brief commentary about the prevalence of this population; and, finally, an exploration of the effective management and possible treatment outcomes.

Findings

Methodological limitations have resulted in variable findings which has hindered our understanding of this population. Some of the research is based on small, highly specialist samples making prevalence difficult to measure. The link between ASD and offending is still not well understood, and despite advances in staff training, awareness amongst practitioners remains an underdeveloped area, thus yielding variable treatment outcomes.

Originality/value

This review continues to demonstrate the urgent need for robust research in order to better understand the link between ASD and offending behaviour, to provide tailored, needs-led interventions, and reduce the risk of offending amongst this group as a whole.

Are we good and are we safe? Measuring quality and assessing risk in an adult autism diagnostic service

Purpose

Leeds autism diagnostic service is an adult autism diagnostic service for people of any intellectual ability which also offers consultancy to service users/carers or professionals, as well as a wide range of autism training. The service was set up as a pilot in 2011 and a paper describing the service development was published in this journal in November 2015. The purpose of this paper is to describe the approach taken to measure the quality of the service the authors provide and accurately assess risk in adults with autism.

Design/methodology/approach

The process of evaluating appropriate outcome measures is described, along with considering appropriate risk assessment tools for use in the community. Over 200 people each year complete the autism diagnostic pathway, and 164 patients were invited to respond to service evaluation questionnaires in 2014.

Findings

To date, the most useful outcome measures for this group include a prospective service user questionnaire which enables service user opinion to influence service development. In the absence of any appropriate autism-specific risk assessment tools, the service has developed one which it is currently piloting. This has proved particularly useful in the consultancy setting

Originality/value

This paper is a follow-up paper looking at the day-to-day issues that the team have had to grapple with – how do you assess whether what you are doing is providing the best possible service for the people that you serve and how do you accurately assess risk in this population?

Autism spectrum disorder traits among prisoners

Purpose

– The purpose of this paper is to determine the extent of autism spectrum disorder (ASD) traits among prisoners. The authors tested the hypotheses that ASD traits would: be continuously distributed among prisoners; be unrecognised by prison staff; and predict whether a prisoner met diagnostic criteria for ASD.

Design/methodology/approach

– ASD traits were measured among 240 prisoners in a male prison in London, UK using the 20-item Autism Quotient (AQ-20). Further diagnostic assessment was carried out using the Autism Diagnostic Observation Schedule. Results were compared with ASD data from the 2007 Psychiatric Morbidity Survey.

Findings

– There were 39 participants with an AQ-20 score=10; indicating significant autistic traits. The distribution of ASD traits among participants appeared to be normal and was not significantly higher than the rate found in a population-based sample from England.

Originality/value

– Few studies have explored ASD traits among prisoners. The authors identified high levels of unrecognised ASD traits among a group of male prisoners, many of whom went on to meet diagnostic criteria for ASD. The study highlights the need for specialist assessment within the criminal justice system for individuals with neurodevelopmental disorders including ASD. The authors discuss the process of carrying out an ASD assessment project in a prison.
