Thirty-three autistic and 30 typically developing (TD) participants were interviewed about their memory for two videos depicting criminal events. Clip segments of one video were ‘scrambled’, disrupting the event’s narrative structure; the other video was watched intact. Autistic people experience social communication difficulties alongside specific memory difficulties that can impact their ability to recall episodic events. Police interviewing techniques do not take account of these differences, and so are often ineffective. Here we introduce a novel Witness-Aimed First Account (WAFA) interview technique, designed to better support autistic witnesses by diminishing socio-cognitive and executive demands through encouraging participants to generate and direct their own discrete, parameter-bound event topics, before freely recalling information within each parameter-bound topic. Since witnessed events are rarely cohesive stories with a logical chain of events, we also explored witnesses’ recall when the narrative structure of the to-be-remembered event was lost. Although both autistic and TD witnesses recalled fewer details with less accuracy from the scrambled video, WAFA interviews resulted in more detailed and accurate recall from autistic and TD witnesses, for both scrambled and unscrambled videos. The WAFA technique may be a useful tool to improve autistic and TD witnesses’ accounts within a legally appropriate, non-leading framework.Autism spectrum disorder (ASD) is diagnosed in around 1% of the population and presents a number of challenges to the day-to-day lives of these individuals as well as their families and support services. This project will provide an evidence base and guide improvements to existing methods used by professional groups to support those with ASD. This will take place in three important information-gathering contexts in which they are currently at a disadvantage. First, only around half of young adults with ASD have worked for pay outside the home - the lowest rate among disability groups. Performance in occupational interviews is a crucial determinant of employment prospects, yet the social, cognitive and communication difficulties of ASD mean they are often unable to perform to the best of their abilities in interviews. Second, people with ASD are more likely to have certain social and health-related issues and co-occurring conditions, and may therefore be more likely to visit health and social care professionals. However, difficulties with introspection and social communication are likely to make relaying relevant information difficult, unless their specific difficulties are appropriately supported. Finally, although individuals with ASD are over-represented in the Criminal Justice System (CJS) as both witnesses (victims) and suspects, current police interviewing models are ineffective in supporting them to provide 'best evidence'. For people with ASD and their families, research on societal issues and improving the lives of ASD individuals is vital. Yet research of this nature is currently lacking. Most services including health and social care, employment and the justice system are developed to cater for "neurotypical" people, or adapted for those with broad intellectual disability. However little consideration or support is in place for the social and cognitive difficulties that are specific to ASD. If individuals with ASD are to receive appropriate and fair access to services and justice, their difficulties must be better understood and accommodated. This begins with their reporting of relevant information to authorities and services. People with ASD show impairments in socio-cognitive domains, including a lack of insight into their own and others' intentions, as well as 'executive functions' (a set of capacities involving cognitive control, regulation, planning and flexibility). As a result, they experience problems in open-ended social situations where the desired response or type of information required from them needs to be inferred. The proposed project will compare how individuals with and without ASD perform on varying social and open-ended tasks. It builds on my existing work to test 1) how the shifting social contexts and increased task complexity inherent in information-gathering interactions in employment, healthcare and CJS contexts might heighten ASD impairments, and 2) how these can be ameliorated with appropriate support. Furthermore, people with ASD can also have areas of strength, and the research aims to determine how these strengths can be utilised to develop interviewing formats that support their difficulties whilst capitalising on their strengths. This research will directly inform best practice in HR, health and social care and the CJS, improving access to services and justice for people with ASD. It will also advance theory by providing new insight into how the social and cognitive difficulties (and strengths) of ASD impact upon real life social interactions. Findings will have implications for national organisations, including the Department of Health, Department for Business Innovation and Skills, Home Office, as well as more local groups, for example, potential employers, police interviewers and health and social care professionals. An extensive program of dissemination to both academic and non-academic stakeholders is planned to maximise the research impact with a broad range of key users.

Note: ASD = autism spectrum disorder; TD = typically developing; WAFA, Witness-Aimed First Account interview The study employed a 2 (Group: ASD vs. TD) x 2 (Interview: WAFA vs. control interview) x 2 (Video: scrambled vs. unscrambled) mixed design, where Video was within participants (counterbalanced between the two videos, groups, and interview conditions). All participants watched two videos, one of which was scrambled, and were interviewed about each video with either a WAFA interview or control interview. The dependent variable was interview performance, measured by the number of correct and incorrect details reported, and overall accuracy scores (correct details as a function of total details recalled). PARTICIPANTS: A total of 63 participants were recruited: 33 autistic adults (27 males) and 30 TD adults (16 males). Autistic participants were recruited through existing databases at the University of Bath and City, University of London, and through ongoing recruitment calls for new participants via social media, local autism networks and organisations, and local newspaper advertisements. All autistic participants had received a formal diagnosis of ASD by experienced clinicians through the UK’s National Health Service according to DSM–IV (American Psychiatric Association, 2000) or DSM-5 criteria (American Psychiatric Association, 2013), which was confirmed with a copy of their original detailed diagnostic report. Those who had received a diagnosis but were unable to produce a detailed letter received the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2; Lord et al., 2012), to confirm their diagnoses.
