Experiences of Autism Spectrum Disorder and Policing in England and Wales: Surveying Police and the Autism Community

What do we know about autism and policing globally? Preliminary findings from an international effort to examine autism and the criminal justice system

Research has demonstrated that autistic individuals have higher rates of police contact, however, research has seldom explored the fundamental reasons for these interactions and how this might vary across international contexts. To remedy this, the Global Autism and Criminal Justice Consortium created and disseminated the Global Criminal Justice Survey. Descriptive statistics of survey respondents with and without police contact were compared to glean differential characteristics. Frequency and type of recent police interactions (within the last 5 years) among autistic individuals were also examined to better contextualize the reasons that autistic individuals encounter police. Study findings indicated that across a global sample (i.e., North America, Scandinavia, Europe, and Oceania) nearly half of all autistic individuals had an interaction with police and that those with a history of police contact were usually older, had higher educational qualifications, and were more likely to have a co-occurring mental health or developmental disorder. Among types of interactions, noncriminal encounters, such as welfare checks, traffic incidents, wandering, and behaviors associated with autism, were most common, followed by autistic individuals alleging a crime was committed against them. These findings offer important directions for future research and for targeted policy responses that can address the unique needs of autistic individuals within the justice system.

Mock Juror Perceptions of Eyewitness Reports Given by Children with Intellectual Disabilities

Previous research suggests that an eyewitness credibility bias can arise when mock jurors are informed of a child's disability diagnosis. The aim of the present study was to examine mock jurors' lie-detection accuracy and credibility perceptions when assessing eyewitness testimonies provided by children diagnosed with an intellectual disability. Adult mock jurors (N = 217; half informed of the child's disability status) read four transcriptions from interviews with children (ages 10 to 15) diagnosed with an intellectual disability before evaluating the credibility and truthfulness of each eyewitness report. The mock jurors' lie-detection accuracy of the eyewitness reports produced by children with an intellectual disability (55.76%) was found to be similar to prior lie-detection research involving typically developing populations. Furthermore, there were no differences in the lie-detection accuracy and credibility ratings between mock-jurors who were informed of the child's disability when compared to those who were not informed. Although mock jurors perceived the children's testimony to have low credibility, they seemed reluctant to consider many of these testimonies to be false. The current findings also suggest that the disclosure of a disability may not independently cause worsened perceptions of child eyewitnesses.

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.

Creating the Global Criminal Justice Survey: A Questionnaire Designed to Gather Perspectives from the Autism Community and Criminal Justice Professionals

Autistic people's perceptions of their interactions with criminal justice professionals are predominantly negative; however, little is known about the state of interactions on a global scale. To further understanding, a comprehensive stakeholder questionnaire was created. Aspects of reliability and validity including evidence for test content and internal structure were gathered using expert reviews, cognitive interviewing, pilot data collection, and a larger data collection effort (N = 1618). Data was gathered from the autism community through perspectives of parents/caregivers as well as from self-reported autistic adults. Criminal justice professionals included law enforcement officers, corrections professionals, probation and parole officers, forensic psychologists and legal professionals. The scale development process was detailed in order to sufficiently document the initial psychometric evidence and share the steps taken to gain diverse stakeholder input. This study is a critical first step in generating further information to facilitate policy and program development with wide applicability.

Knowledge and Perspectives of Developmental Language Disorders: The Pilot Development of a Survey of Professionals Working in Law Enforcement

PURPOSE

The purpose of this study was to pilot test a survey of professionals within the justice system about their knowledge and perceptions of developmental language disorders (DLDs) and to gather initial data supporting their knowledge and perceptions.

METHOD

One hundred thirty-six adults in Texas with law enforcement jobs, primarily police officers, participated in this study. Participants completed a survey consisting of 78 questions about their background, experiences with DLD, and beliefs about communication. Additionally, 42 adults who did not work in law enforcement completed the survey twice to establish the initial measures of survey reliability.

RESULTS

This survey demonstrated sufficient test-retest reliability with adults not in law enforcement, and results indicated the emergence of two subscales within the survey. Law enforcement professionals appeared to have limited knowledge of DLD, and many linked language-related behaviors with credibility. A majority did agree with giving accommodations to individuals who struggle with language and reported interest in receiving training to recognize and accommodate DLD.

CONCLUSIONS

This pilot study demonstrates a need for collaboration between speech-language pathologists and law enforcement professionals and provides data for a survey that could be used across professional groups in the justice system to measure knowledge and perspectives of DLDs. This work represents an initial step in an iterative process of survey development for law enforcement professionals.

Language is a critical mediator of autistic experiences within the criminal justice system

Autism spectrum disorder is characterized by social communication challenges and restricted and repetitive behaviors and interests, but also by highly heterogeneous language skills. The recent International Society of Autism Research (INSAR) policy statement, Autism and the Criminal Justice System: Policy opportunities and challenges (INSAR, 2022), aims to prevent, reduce, and improve interactions between autistic individuals and the criminal justice system. This policy statement provides a foundation for considering how to include language in these important aims. In this commentary, we outline the centrality of language skills to these interactions and provide specific recommendations that can inform future research and provide guidance for autistic individuals, community partners, and individuals working within the criminal justice system. Considering language as a part of justice system policy for autistic individuals will result in greater equity and inclusion, particularly for autistic individuals with co-occurring language deficits and those who are linguistically diverse. Moreover, it will allow autistic individuals to combat other barriers to effectively navigating interactions with the criminal justice system, such as those related to the core features of autism. We advocate for a greater role for service providers who can assess challenges in language skills, and identify the specific accommodations each autistic individual will need to prevent, reduce, and improve interactions with the criminal justice system.

Autism Training for Law Enforcement Officers: A Scoping Review

Law enforcement officers are the primary individuals called and who respond to situations of heightened concern. They make split-second observations and decisions based on how best to react to given safety situations and those involved. Characteristics of autism spectrum disorders (ASD), if not properly understood and reacted to, may quickly escalate a law enforcement officer call in a negative way, making autism training for law enforcement officers imperative. To ascertain what is known about autism training for law enforcement officers, a scoping review was conducted. Five studies met final inclusion criteria. The trainees, context and development of the training, evaluation procedures, and training outcomes are synthesized to provide guidance for future training implementation teams. Areas for future research are presented.

Forensic interviews conducted with autistic adults in Japan: a review of the literature and directions for future research

The interviewing of victims, witnesses and suspects is important in helping resolve criminal investigations. In Japan, developments have recently occurred in the training of the police and their public prosecutors in these key tasks. Whilst literature exists on autism in Japan, studies examining police/public prosecutor interviews with autistic adults conducted in that country (and indeed, any other) remain scant. As elsewhere in the world, identification of those who manifest characteristics prevalent on the autism spectrum disorder (ASD) scale, has been found to be problematical to criminal justice professionals. To help address this deficit in understanding, we provide an overview of the literature concerning contemporary understanding of the challenges facing autistic adults as they attempt to reveal their verbal accounts, as well as suggested techniques when interviewing adults on the ASD scale during criminal investigations, offering lessons learned from research conducted around the world that provide potentially promising solutions for Japan.

Preparing Law Enforcement Officers to Engage Successfully with Individuals with Autism Spectrum Disorder: An Evaluation of a Performance-Based Approach

Law enforcement officers (LEOs) may use physical force unnecessarily or escalate problem behavior when attempting to gain the compliance of individuals with autism spectrum disorder (ASD) (Copenhaver & Tewksbury in American Journal of Criminal Justice 44:309-333, 2019). Although specialized training may remedy this problem, the relatively small literature on such training programs indicates the need for further research (Railey et al. in Focus on Autism and Other Developmental Disabilities, 2020). This study used simulations with actors to evaluate the outcomes of performance-based instruction on strategies to promote compliance when LEOs respond to calls involving individuals with ASD. Results for three LEOs and 24 police cadets demonstrated the efficacy of behavioral skills training (BST) for teaching LEOs how to interact more effectively with individuals with ASD. Results also suggested that hands-on training should supplement commonly used forms of didactic instruction.

Pilot Survey: Police Understanding of Autism Spectrum Disorder

This piliot study assessed the experiences of police officers related to persons with Autism Spectrum Disorder (ASD) via a survey assessing prior experience, comfort, knowledge, and ability to identify autistic persons. Fifty-one officers completed the survey: 52.9% reported previous ASD training, 34.8% reported personal experience with ASD, and 56.9% endorsed low overall knowledge of ASD. Officers reported neutral comfort (mean 3.24) and moderate practical knowledge (mean 3.74) [Likert scale 1-5; 5 = highest]. Those with previous training or with personal experience reported higher comfort and knowledge. Those with personal experience were more likely to recognize features of ASD in clinical vignettes. Further study is necessary to understand what additional training about ASD may be helpful to police officers.

Police suspect interviews with autistic adults: The impact of truth telling versus deception on testimony

Investigative interviews by police are socially and cognitively demanding encounters, likely presenting significant challenges to those on the autism spectrum. Behavioral and communication differences mean that autistic people may also be more likely to be perceived as deceptive in the context of an investigative interview. In the present study, 32 autistic and 33 (age and IQ-matched) non-autistic adults took part in a novel virtual burglary scenario in either an 'innocent' or 'guilty' condition. In a subsequent mock-police interview, innocent suspects were instructed to tell the truth about what they did, while guilty suspects were instructed to lie in order to convince the interviewer of their innocence. In the mock-interviews, innocent autistic mock-suspects reported fewer details that would support their innocence than non-autistic mock-suspects, although both innocent and guilty autistic and non-autistic mock-suspects reported similar levels of investigation-relevant information and had similar levels of statement-evidence consistency. In post-interview questionnaires, innocent and guilty autistic mock-suspects self-reported greater difficulty in understanding interview questions, higher anxiety and perceived the interview as less supportive than non-autistic participants. Implications for investigative interviewing with autistic suspects and cues to deception are discussed.

Are autistic people disadvantaged by the criminal justice system? A case comparison

LAY ABSTRACT

Most autistic people will never experience being arrested or charged with a crime, however for those who do tend to be less satisfied with the way they were treated. The purpose of this study was to find out if autistic people are being disadvantaged by the criminal justice system if they are arrested. Previous research has shown that autistic people may have difficulties communicating with the police. This study builds on this knowledge by uncovering why autistic people may not feel able to communicate with the police and whether the police made any adjustments to help them. This study also measures the impact of being involved with the criminal justice system on autistic people's mental health, such as stress, meltdowns and shutdowns. The results show that autistic people were not always given the support they felt they needed. For example, not all autistic people had an appropriate adult with them at the police station who could help to make sure they understood what was happening around them. Autistic people were also more likely to feel less able to cope with the stress and more likely to suffer meltdowns and shutdowns because of their involvement with the criminal justice system. We hope this study will help police officers and lawyers to better support autistic people if they become involved with the criminal justice system.

Law enforcement officers' interactions with autistic individuals: Commonly reported incidents and use of force

Little research exists examining interactions between law enforcement officers (LEOs) and autistic individuals. The present study includes responses from 130 LEOs who participated in autism-specific training and completed surveys assessing professional experiences responding to calls that involved individuals with known autism spectrum disorder (ASD) diagnosis. The purpose of the present study was to determine the types of incidents LEOs respond to involving autistic people, and the level of force used in response to the incident. Analysis revealed four categories captured the majority of reported incidents: disruptive behavior, suspected abuse/neglect, elopement, and noncriminal behavior. The most commonly reported responses by LEOs included providing support and extreme controlling behaviors, with female officers more likely to report utilizing supportive behaviors and less force compared to male counterparts.

A Systematic Review of Autistic People and the Criminal Justice System: An Update of King and Murphy (2014)

The purpose of this paper was to determine whether recommendations made by King & Murphy (Journal of Autism and Developmental Disorders 44:2717-2733, 2014) in their review of the evidence on autistic people in contact with the criminal justice system (CJS) have been addressed. Research published since 2013 was systematically examined and synthesised. The quality of 47 papers was assessed using the Mixed Methods Appraisal Tool. Findings suggest a limited amount of good quality research has been conducted that has focused on improving our understanding of autistic people in contact with the CJS since 2013. Methodological limitations make direct comparisons between autistic and non-autistic offenders difficult. Autistic people commit a range of crimes and appear to have unique characteristics that warrant further exploration (i.e., vulnerabilities, motivations for offending).

Autism and the criminal justice system: An analysis of 93 cases

We investigate whether autistic people's vulnerability is taken into account at each stage of the criminal justice system (CJS). Defense lawyers from 12 nations were included in the study although the sample was predominantly from the UK. Lawyers completed an online survey regarding one case in which they had defended an autistic client between January 2015 and January 2020; and on one case in which they had defended a nonautistic client charged with a similar offense, to provide a comparison group. Ninety-three lawyers (85% in the UK) reported on one autistic case, and 53 also reported on one nonautistic case. 75% of autistic clients were not given reasonable adjustments during the process. Only 43% were offered an appropriate adult during police investigations, even though they had an existing diagnosis of autism. 59% of prosecution barristers and 46% of judges said or did something during the trial that made the lawyers concerned that they did not have an adequate understanding of autism. Lawyers were 7.58 times more likely to be concerned about their autistic client's effective participation in court and were 3.83 times more likely to be concerned that their autistic clients would engage in self-harm, compared with their nonautistic clients. There is a failure to identify and address autistic peoples' disability within the CJS. There is a need for mandatory autism training for police officers and the judiciary, with a focus on identifying autism and understanding the needs of autistic people so that reasonable adjustments are offered in all cases. LAY SUMMARY: This study sought to investigate if the needs of autistic people are being overlooked by the police and other professionals within the CJS. Results show that autistic people are not always given the support they need during police questioning or in court. The experience of being involved with the police may also have a more negative impact on autistic peoples' mental health than that of nonautistic people.

Policy gaps and opportunities: A systematic review of autism spectrum disorder and criminal justice intersections

Autism spectrum disorder prevalence is rising, and as this population enters adulthood, preliminary research has identified high rates of contact with the criminal justice system. Policy and programmatic reform are crucial given reported negative and violent outcomes for autistic individuals when encountering the criminal justice system. Given the size and scope of the entire criminal justice system, identifying priorities and opportunities for change is critical, and must be rooted in evidence-based findings to maximize impact and scalability. This article provides a systematic review of the literature on autism spectrum disorder and criminal justice system intersections, analyzed through a convergent qualitative synthesis. As the extant literature is diverse and employs a variety of study methods, this review allows for an analysis across study types. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis structure was utilized and captured 89 total articles from six databases. Studies are grouped by the Sequential Intercept Model, which offers a framework for analyzing criminal justice system dimensions, and informs where research at the intersection of autism spectrum disorder and the criminal justice system is most prevalent. Themes were identified at each intercept and described through key study findings to articulate implications and guidance for policy, practice, and future research to promote equitable justice for autistic individuals.

Lay abstract

The number of people with autism spectrum disorder has increased, and as this population ages, research is showing high rates of contact with the criminal justice system among this group. Social and communication differences that autistic individuals experience can act as a risk factor during these interactions, as shown by public reports of negative and violent encounters between autistic individuals and the law enforcement. There is a clear need for evidence-based strategies to reduce high rates of contact and to improve outcomes when an interaction occurs. This article provides a systematic review of research on autism spectrum disorder and criminal justice system to compile this evidence base. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis structure was used to identify 89 articles after searching six databases. The Sequential Intercept Model describes the criminal justice system as different stages, or intercepts, that are connected, and the Sequential Intercept Model serves as an overall framework to organize the included articles. Articles were analyzed to identify research themes at each intercept, which offer guidance for policy and program changes that support equitable justice for autistic individuals.

Toward Empathetic Autism Research: Developing an Autism-Specific Research Passport

Autistic adults sometimes report negative experiences of research participation. People have developed passports or toolkits in other areas where community members report dissatisfaction (e.g., health care, criminal justice). We created a Research Passport that autism researchers and autistic adults could use to support the inclusion of autistic adults as research participants. We designed and developed the Research Passport via an iterative design process. First, we gathered ideas for a Research Passport via focus groups with autistic adults without an intellectual disability (ID) (n = 9) and autism researchers (n = 6; one of whom was autistic). We found that the Research Passport (1) was a useful idea, but not a panacea for all issues in autism research, (2) needed to be universal and flexible, and (3) could have a broad remit (e.g., to record scores on commonly used standardized tasks that could, with permission, be shared with different researchers). Next, we conducted a preliminary evaluation of a prototype Research Passport via usability testing in three ongoing research projects. Nine autistic participants without an ID provided feedback on the Research Passport (via a survey), as did three nonautistic researchers (via interviews). We found that the Research Passport (1) promoted positive participant-researcher relationships, (2) provided a structure and framework to support existing practices, and (3) needed to be adapted slightly to facilitate usability and manage expectations. Overall, the Research Passport was useful in promoting empathetic autism research. Further design and development of the Research Passport are warranted.

Lay summary

Why was this research developed?: Autistic adults taking part in research do not always have good experiences. An autistic member on our team thought that a Research Passport could help improve people's experiences. This idea was inspired by "passports" or "toolkits" that autistic people can use when visiting professionals such as doctors (so the doctor knows about the person and how to support them).What does the Research Passport do?: The Research Passport lets autistic people tell researchers about themselves before taking part in a research study. Autistic people can decide how much, or how little, they tell the researcher. Autistic and/or nonautistic researchers can use the Research Passport to try and make sure that their autistic participants have good experiences when taking part in research.How did the researchers evaluate the Research Passport?: First, nine autistic adults (who did not have an intellectual disability) and six autism researchers took part in group discussions. We asked what they thought about our Research Passport idea and what it should include. We made a Research Passport mock-up based on these discussions. Nine autistic participants who did not have an intellectual disability used the mock-up in one of three university research projects. Autistic participants completed a survey to tell us good and not-so-good things about the Research Passport. Also, we interviewed three researchers about using the Research Passport (asking what they liked and what could have been better).What were the findings?: Autistic adults and researchers involved in designing the Research Passport thought the Research Passport (1) could be useful but could not solve all problems in autism research, (2) needed to be suitable for many different people, and (3) could have many different benefits (e.g., collecting participants' scores on tests that researchers use a lot, so participants do not have to keep doing the same tests each time they take part in a new research study).Autistic adults and researchers used the Research Passport in ongoing studies and told us that it (1) led to good relationships between participants and researchers, (2) helped researchers make sure that the way they did their research was acceptable, and (3) was useful. However, participants need to be told what the Research Passport can/cannot help them with.What were the weaknesses of this project?: This study involved a small group of autistic adults and researchers, and the results may not be the same with autistic adults and researchers who have different needs. Also, participants said the Research Passport was not very easy to complete, and a bit long. We need to change the Research Passport so that a wider range of autistic people (like those with intellectual disability) can use it.What are the next steps?: The Research Passport needs to be professionally designed so it is easier to be used by a wider range of autistic people. A bigger evaluation of the Research Passport could allow us to test it with more participants and in more research studies.How will this work help autistic adults now or in the future?: Using the Research Passport could, with some changes and alongside other supports, improve the experience of autistic adults taking part in research.

Autistic adults and their experiences with police personnel: a qualitative inquiry

This study uses a qualitative methodological approach to investigate the experiences that autistic adults have when encountering police personnel. An anonymous, online, semi-structured survey asking open-ended questions about individual experience was used, and the data were analysed thematically. Although only five participants comprised the final sample, the findings illustrate how - despite differences in types of interaction and police contact - similar experiences were reported. Almost all participants reported experiencing a negative interaction with police, coupled with a limited understanding of the events surrounding their encounter. Four participants experienced some form of being stopped and questioned. This study aims to examine alternative perspectives, as previous research has focused on criminal justice personnel perspectives rather than autistic perspectives. This is one of a few qualitative Australian studies to seek individualised experiences from a community-based sample. Sampling and recruitment strategies need revision to attain a larger number of surveys in future research.

Law Enforcement Officers' Preparation for Calls Involving Autism: Prior Experiences and Response to Training

Highly publicized interactions between law enforcement officers (LEOs) and individuals with autism spectrum disorder (ASD) have raised questions about LEOs' training related to ASD. In the present study, 157 LEOs participated in ASD-specific training and completed pretest and posttest surveys of autism knowledge, confidence, and self-monitoring. The majority of LEOs responded to calls involving someone with ASD in the last year, with 20% of these calls resulting in involuntary psychiatric hospitalization. LEO knowledge of ASD, self-confidence in responding to calls, and self-monitoring of performance increased from pretest to posttest. Compared to male counterparts, female officers were less likely to use force and handcuffs when responding to ASD-related calls. Female officers' self-confidence increased significantly more than male officers.

Perspectives from the ASD community on police interactions: Challenges & recommendations

BACKGROUND

Research shows that a substantial proportion of people with Autism come into contact with the police in their lifetime, and some research suggests that they are largely unsatisfied with their police interactions.

METHOD

Thirty-five adults with ASD completed an online questionnaire regarding the challenges police may face when interacting with Autistic people, as well as provided recommendations as to how those interactions could be improved.

RESULTS

Respondents reported a variety of different potential challenges that could present in an interaction between the police and people with ASD. For example, respondents felt that typical Autistic behaviours, such as stimming or communication difficulties, could be misinterpreted by police officers and lead to adverse outcomes. Respondents discussed several recommendations aimed at improving police interactions with Autistic people, including involving Autisitc people in the training of police officers.

CONCLUSIONS

The information collected in this study provides insights into how interactions between the police and people with ASD can be improved. These findings can be used in the development of police training programs or integrated into pre-existing training programs on Autism, contributing the invaluable perspective of the Autism community.

Interviewing alleged victims with mild and moderate intellectual disabilities and autism: A field study of police-investigated cases of physical and sexual abuse in a Norwegian national sample

BACKGROUND

People with intellectual disabilities (IDs) or autism are at great risk of being victims of physical and sexual abuse. This study uses transcriptions of real-life investigative interviews to examine the interview techniques (e.g. question type) used in investigative interviews of these groups of alleged victims.

METHODS

A national sample of transcribed investigative interviews (N = 96) of alleged victims with mild ID (n = 48, age 5-70 years old), moderate ID (n = 18, age 14-43 years old) and autism (n = 16, age 5-50 years old) was analysed.

RESULTS

The study shows a preponderance of alleged sexual offences (70.7%) and reveals that open-ended questions account for only 2.6% of the total number of questions asked. The interviewers relied heavily on yes/no (53.4%) and directive questions (32.2%). Suggestive questions (8.6%) were frequently used.

CONCLUSIONS

The use of question type varied considerably within and across the diagnostic group. The study reveals the need for a more in-depth analysis of variables that influence investigative interviews of people with cognitive impairments.

Autistic adults' views of their communication skills and needs

BACKGROUND

Autistic people require varying levels of support at different stages of their lives. Yet, the healthcare needs of autistic adults are largely unmet. Speech and language therapy (SLT) is one healthcare service that has an important role in supporting autistic people: both with initial diagnosis, and with the ongoing support needed to navigate different communicative challenges across the lifespan. Despite recommendations for such support, currently there is no clear SLT pathway for autistic adults, and a lack of established approaches to support autistic adults' speech, language and communication needs.

AIMS

To seek autistic adults' views on (1) their communication skills and support needs; (2) the type of support SLT could offer; and (3) how such support could be provided.

METHODS & PROCEDURES

A total of 18 autistic adults were interviewed in their preferred mode of communication (e.g., face to face, phone call, text messaging, e-mail), expressing their views on their communication skills and needs. Interview data were analysed using thematic analysis.

OUTCOMES & RESULTS

Autistic adults presented complex views on communication, identifying the benefits of communication, while also emphasizing the significant negative impact that communication difficulties can have on their everyday lives. Identifying a range of internal (e.g., personal feelings) and external (e.g., the communication partner) factors, they highlighted the need for support at both individual levels (for specific life situations) and broader societal levels (to increase awareness and acceptance of communication difficulties).

CONCLUSIONS & IMPLICATIONS

Considering the negative impact that communication difficulties can have for autistic adults, a need for support was emphasized. Despite recognition of this need within current legislation (in the UK) and positive steps toward providing support, more needs to be done. As experts in supporting individuals with communication difficulties, speech and language therapists could play a pivotal role in providing support at an individual level, as well as increasing awareness of communication differences more widely. What this paper adds What is already known on this subject There is a growing population of autistic adults with unmet support needs. A core characteristic of autism is difficulty with neurotypical social communication and interaction, which persists into adulthood and impacts across various life domains. What this paper adds to existing knowledge Autistic adults outlined the types of communication difficulties they experience, and how these can negatively impact on physical and mental health. Results highlight how these difficulties are not just rooted within the person themselves but can be influenced by external factors (e.g., the environment and the communication partner). What are the potential or actual clinical implications of this work? Some autistic adults may benefit from direct support from SLT services. However, increased awareness and respect for communication differences at a broader societal level is also needed. Speech and language therapists can play an important role in increasing this level of awareness, positively highlighting differences in communication and ways to support people with communication difficulties/differences.

Does a Person's Autism Play a Role in Their Interactions with Police: The Perceptions of Autistic Adults and Parent/Carers

This study aimed to describe the impact that autistic characteristics (core features of autism and co-occurring conditions) have on interactions with police. Twelve autistic adults and 19 parent/carers were interviewed about interactions with police in the past 5 years. Using content analysis, it was found that in most (92.3%) interactions, autistic characteristics were described as having a role in the police interaction, either as a causal factor or more commonly by affecting the conduct of the interaction. In the latter case, the impact was associated with negative perceptions of the interaction. By sampling a more representative group across age, gender, functional abilities and context, this study provides insight into factors that underlie many autistic individual's reported dissatisfaction with police interactions.

Appropriate adults: Their experiences and understanding of Autism Spectrum Disorder

An appropriate adult (AA) is required by law, to support juveniles and vulnerable adults during custody procedures. This paper explored the opinions and knowledge of AAs and how the characteristics of Autism Spectrum Disorder (ASD) could disadvantage an individual within a police interview. A questionnaire was administered to AAs who had received training to carry out their duties (N = 55). AAs were asked a number of questions concerning suspects with ASD. Overall, the questionnaire found that AAs had some awareness of the key features of ASD. However, AAs were less aware of the possible impact these characteristics could have upon the interview process. Nevertheless, when asked about actual practice, fifteen incidents were reported where it was deemed that the characteristics of ASD disrupted interview procedures. For example, it was reported that suspects with ASD displayed repetitive and rigid behaviour patterns that interfered with the flow of the interview. Encouragingly, the self-reported data suggested that AAs were able to respond effectively to these actual incidents. That withstanding it is suggested that AA training should include information about how those with ASD might be at a disadvantage within the forensic interview environment and outline strategies that AAs could use to help a person with ASD fully engage within the criminal justice process.

Measuring Police Officer Self-efficacy for Working with Individuals with Autism Spectrum Disorder

Autism spectrum disorder (ASD) is currently one of the most researched of all childhood developmental disorders and is receiving attention in many domains. The purpose of this study was to design and provide psychometric evidence for a scale that measures police officer self-efficacy for working with individuals with ASD. Psychometric properties of a scale designed to measure knowledge of ASD were also explored. Data from 620 police officers were collected and a 13-item scale was created and evaluated. Results indicated that the scale represented a unidimensional construct. Knowing more about officers' knowledge and beliefs in their own capabilities to work with individuals with ASD can help inform future police education and training efforts.

Experiences of people with intellectual disabilities encountering law enforcement officials as the suspects of crime - A narrative systematic review

It is well established internationally that there is a high prevalence of intellectual disability (ID) among people in police custody. Some people with ID may face particular challenges in negotiating the forensic formalities adopted by police at the pre-trial stage of the criminal process. These challenges need to be acknowledged and mitigated through appropriate procedural safeguards in order to, at once, preserve the fact-finding accuracy of criminal investigations and minimise the risk of securing a wrongful conviction. And yet, despite the formative role which pre-trial procedures exert over the trajectory of proceedings, little is known about the experiences of people with ID during their initial interaction with law enforcement officers. In an attempt to address this research lacuna, we reviewed six databases systematically to identify studies that explore such experiences. Seven studies with a total of 1199 participants were identified. Frequently, participants with ID describe challenges in police custody, experiencing particular difficulties in understanding and communicating information. They report a paucity of appropriate supports generally in this setting and an unmet need for the provision of procedural and emotional supports. Consistent implementation of legal safeguards is necessary, along with consistent availability of accessible practical measures to support people with ID within the criminal justice system.

Investigative interviewing of youth with ADHD - recommendations for detective training

Attention deficit hyperactivity disorder (ADHD) in youth can lead to a trajectory of early and repeated contact with the criminal justice system (CJS), where such youth face significant challenges due to the nature of their diagnosis and the lack of specialized detective training in this area. This article reviews Australian detectives' perceptions regarding contact with ADHD-affected youth, ongoing contact of such youth with the CJS, and the impact of ADHD on interviewing time efficiency and quality of information gathered. It explores detectives' perceived impact of ADHD on components of the Cognitive Interview (CI). It overviews detectives' perceptions regarding their own skill/ability, training availability and future training preferences regarding the interviewing of ADHD-affected youth. The authors highlight best practice in specialized detective training, as well as in working with ADHD-affected youth. Recommendations are made regarding the design features of a potential specialized training programme for detectives interviewing ADHD-affected youth.

Exploring the autistic and police perspectives of the custody process through a participative walkthrough

BACKGROUND

Research suggests that autistic individuals may be more likely to come into contact with police and have more negative experiences in police custody. However, limited information about the difficulties they experience during the custody process is available.

AIMS

This study explores the experiences of autistic individuals and officers during a walkthrough of the custody process to identify specific difficulties in these encounters and what support is needed to overcome these.

METHODS AND PROCEDURES

A participative walkthrough method was developed to provide autistic individuals and officers an interactive opportunity to identify areas where further support in the custody process was needed. Two autistic participants and three officers took part in the study.

OUTCOMES AND RESULTS

Autistic participants reported negative experiences due to: i) the emotional impact of the physical setting and custody process ii) communication barriers leading to increased anxiety and iii) exposure to sensory demands. Officers highlighted three factors which limit their ability to support autistic individuals effectively: i) the custody context ii) barriers to communication and iii) knowledge and understanding of autism.

CONCLUSIONS AND IMPLICATIONS

Adjustments are needed to the custody process and environment to support interactions between autistic individuals and officers and improve the overall wellbeing of autistic individuals.

Collaborating with Families and Law Enforcement Agencies to Improve Outcomes for Individuals with Autism Spectrum Disorder

Increased visibility of adverse encounters between individuals with autism spectrum disorder (ASD) and law enforcement (LE) has stimulated a dialog among providers. There are a variety of contributing factors to the increase, including the recognized lack of training of LE professionals on the needs of individuals with ASD and the paucity of awareness of resources by the families of these individuals. The aim of this article is to provide insight into developmental-behavioral pediatric professionals, to enhance safety and reduce adverse outcomes for individuals with ASD in schools and the community.

The Vulnerability Experiences Quotient (VEQ): A Study of Vulnerability, Mental Health and Life Satisfaction in Autistic Adults

Co‐morbid mental health conditions such as anxiety and depression are extremely common in autistic adults. Vulnerability to negative life experiences such as victimisation and unemployment may be partially responsible for the development of these conditions. Here we measure the frequency of negative life experiences in autistic adults and explore how these are associated with current anxiety and depression symptoms and life satisfaction. We developed the Vulnerability Experiences Quotient (VEQ) through stakeholder consultation. The VEQ includes 60 items across 10 domains. Autistic adults with a clinical diagnosis and non‐autistic controls completed the VEQ, screening measures for anxiety and depression, and a life‐satisfaction scale in an online survey. Likelihood of experiencing each VEQ event was compared between groups, using binary logistic regression. Mediation analysis was used to test whether total VEQ score mediated the relationship between autism and (1) depression (2) anxiety and (3) life satisfaction. Autistic adults (N = 426) reported higher rates of the majority of events in the VEQ than non‐autistic adults (N = 268). They also reported more anxiety and depression symptoms and lower life satisfaction. Group differences in anxiety, depression and life satisfaction were partially mediated by VEQ total score. This study highlights several important understudied areas of vulnerability for autistic adults, including domestic abuse, contact with social services (as parents) and financial exploitation and hardship. Improved support, advice and advocacy services are needed to reduce the vulnerability of autistic adults to negative life experiences, which may in turn improve mental health and life satisfaction in this population.

Lay Summary

This study investigated whether autistic adults are more vulnerable to certain negative life experiences, and whether these experiences are related to anxiety, depression and life satisfaction. We found that autistic adults are more vulnerable to many different negative life events, including employment difficulties, financial hardship and domestic abuse. Negative life experiences partially explained the higher rates of anxiety and depression symptoms and lower life satisfaction in autistic adults compared to non‐autistic adults. Improved support services are required to reduce the vulnerability of autistic adults. Reducing vulnerability may improve mental health and increase life satisfaction in this population.

A mixed-methods study of police experiences of adults with autism spectrum disorder in Canada

The current study examined the experiences and perceptions of people with Autism Spectrum Disorder (ASD) in relation to their interactions with the police. Thirty-five adults with ASD living in Canada completed a detailed survey that probed their experiences with police in depth. Amongst respondents, police contact was common and frequent, occurring under a diverse range of circumstances. More than three-quarters of respondents reported at least one lifetime police interaction, with 53% of respondents reporting four or more. The majority of respondents viewed their police interactions unfavourably, and many reported experiencing adverse effects. Results suggest that this negativity toward their police encounters may be largely due to the fact that police are unaware they are interacting with someone with ASD, and perhaps also a lack of resources available to police officers for people with ASD. Findings provide insights into the nature of police encounters amongst individuals with ASD, emphasizing how interactions between people with ASD and the police may be improved in the future.

Mock Juror Perceptions of Credibility and Culpability in an Autistic Defendant

One-hundred-and-sixty jury-eligible participants read a vignette describing a male who was brought to the attention of police for suspicious and aggressive behaviours and displayed atypical behaviours in court. Half of participants were informed that he had autism spectrum disorder (ASD) and were given background information about ASD; the other half received no diagnostic label or information. The provision of a label and information led to higher ratings of the defendant's honesty and likeability, reduced blameworthiness, and resulted in fewer guilty verdicts, and more lenient sentencing. Thematic analysis revealed that participants in the label condition were more empathetic and attributed his behaviours to his ASD and mitigating factors, while participants in the No label condition perceived the defendant as deceitful, unremorseful, rude and aggressive.

Mock Juror Perceptions of Child Witnesses on the Autism Spectrum: The Impact of Providing Diagnostic Labels and Information About Autism

Research suggests that autistic children can provide accurate and forensically useful eyewitness evidence. However, members of a jury also rely on non-verbal behaviours when judging the credibility of a witness, and this could determine the verdict of a case. We presented mock jurors with videos (from an experimental study) of one of two child witnesses on the autism spectrum being interviewed about a mock minor crime. Results demonstrated that providing jurors with generic information about autism and/or informing them of the child’s diagnostic label differentially affected credibility ratings, but not for both children. Implications for how to present information about child witnesses with autism to a jury—highlighting the need for approaches tailored to individual children—are discussed.

Emergency service experiences of adults with autism spectrum disorder without intellectual disability

This study aimed to describe patterns of emergency department use and police interactions, as well as satisfaction with emergency services of 40 adults with autism spectrum disorder without intellectual disability over 12–18 months. Approximately 42.5% of the sample reported visiting the emergency department and 32.5% reported interactions with police during the study period. Presenting concerns for emergency department use and police interactions varied widely, highlighting the heterogeneous needs of this population. On average, participants reported being dissatisfied with care received in the emergency department while police interactions were rated relatively more favourably.

Changes in the frequency and characteristics of children diagnosed with autistic disorder in two Norwegian cohorts: 1992 and 2009

Background:

Is the increasing prevalence of autistic disorder (AD) a well-documented trend or merely a reflection of the wider recognition of AD among both the public at large and health care professionals? Data from relevant studies are frequently compromised by comparisons of different sites and different diagnostic methods.

Objectives:

To explore changes over time, we reviewed the following: 1) the frequency of AD diagnoses; 2) the characteristics of the diagnosed children; and 3) the ages of the children when initial concerns were addressed and AD diagnoses made.

Method:

We compared the case records of children between the ages of 1 and 17 years who were residing in Nordland County, Norway, and who were diagnosed with AD during two different data collection periods: 1992 (Cohort 1) and 2009 (Cohort 2).

Results:

In Cohort 1, 28 children were diagnosed with AD; 71 children in Cohort 2 received AD diagnoses. The increase was greatest among children with intelligence quotient (IQ) values of at least 70. The proportion of children with genetic syndromes was around 20% in both cohorts. Median age at AD diagnosis did not differ between the two cohorts (4.5 vs. 5.0 years, respectively). When the two cohorts were combined, children with IQ values of 70 or more without a genetic syndrome and those with IQ values of less than 50 with genetic syndromes were diagnosed at approximately the same age (5.5 and 5.3 years, respectively). Both groups were significantly older at diagnosis as compared with children with IQ values of less than 50 without genetic syndromes (3.5 years).

Conclusions:

The increase in the number of children diagnosed with AD is consistent with findings from international studies. Contrary to predictions, the age at diagnosis was not reduced over time. A higher proportion of children with IQ values in the average range in the latter cohort may have contributed to this. A delayed diagnosis of AD among children with genetic syndromes may indicate that early autism symptoms are attributed to the genetic condition. Clinical implications are discussed.
