Deficits in episodic free-recall memory performance have been reported in children with autism spectrum disorder (ASD), yet best practice dictates that child witness/victim interviews commence with a free-recall account. No ‘tools’ exist to support children with ASD to freely recall episodic information. Here, the efficacy of a novel retrieval technique, Sketch reinstatement of context (Sketch-RC), is compared with mental reinstatement of context and a no support control. Ninety children (45 with ASD; 45 matched typically developing) viewed a stimulus film, and were interviewed using one of the aforementioned techniques. The Sketch-RC technique was most effective, improving ASD participants’ remembering without a concomitant increase in intrusions. This procedure offers a population-appropriate method for supporting free recall in criminal justice settings.

The success of witness interviews in the criminal justice system depends on the accuracy of information obtained, which is a function of both amount and quality of information. Attempts to enhance witness retrieval such as mental reinstatement of context have been designed with typically developed adults in mind. In this article, the relative benefits of mental and sketch reinstatement mnemonics are explored with both typically developing children and children with autism. Children watched a crime event video, and their retrieval of event information was examined in free and probed recall phases of a cognitive interview. As expected, typically developing children recalled more correct information of all types than children with autism during free and probed recall phases. Sketching during free recall was more beneficial for both groups in both phases in reducing the amount of incorrect items, but the relative effect of sketching on enhancing retrieval accuracy was greater for children with autism. The results indicate the benefits of choosing retrieval mnemonics that are sensitive to the specific impairments of autistic individuals and suggest that retrieval accuracy during interviews can be enhanced, in some cases to the same level as that of typically developing individuals.

Since 2004, witness intermediaries have been utilised across the justice system in England and Wales. Two witness intermediary schemes based on the English model have also been introduced in Northern Ireland (2013), and more recently, in New South Wales, Australia (2016). The purpose of the intermediary in these jurisdictions is to facilitate the questioning of vulnerable witnesses, but there are clear differences in the application of the role. This paper presents the first comparative review of the three related intermediary models, and highlights the pressing need for further research into the efficacy and development of the role in practice.

ABSTRACT There is a dearth of research investigating psychosocial correlates of attitudes toward reporting child sexual abuse in males and females and a lack of such studies drawing on participants from the United Kingdom. Therefore, the main objective of this article is to examine gender differences in social and psychological predictors of attitudes toward reporting child sexual abuse. Participants drawn from the United Kingdom general population were recruited via an opportunistic sampling method. Cross-sectional design using a self-report questionnaire was utilized. Hierarchical multiple regression analyses revealed that social support, masculinity, and age form significant associations with attitudes toward reporting child sexual abuse in females (total variance explained by the model was 25%). In the male sample, the only significant predictor of attitudes toward reporting child sexual abuse was interpersonal manipulation (total variance explained by the model was 9%). This study provides an important insight into psychosocial barriers and facilitators to reporting child sexual abuse. Such knowledge is crucial for the early detection and prevention of abuse.

Recently, Henry et al. (J Autism Dev Disord 8:2348–2362, 2017) found no evidence for the use of Verbal Labels, Sketch Reinstatement of Context and Registered Intermediaries by forensic practitioners when interviewing children with a diagnosis of autism spectrum disorder. We consider their claims, noting the limited ecological validity of the experimental paradigm, the impacts of repeated interviewing where retrieval support is not provided at first retrieval, question the interviewer/intermediary training and their population relevant experience, and comment on the suppression of population variances. We submit that rejecting these techniques on the basis of this study is completely unwarranted and potentially damaging, particularly if used in legal proceedings to undermine the value of testimony from children with ASD, who continually struggle to gain access to justice.

It is a widely held belief that questioning vulnerable witnesses is a specialist skill. In England and Wales vulnerable witness advocacy training built around ‘20 Principles’ has been developed and is being delivered. The 20 Principles do not cite a tested theoretical framework(s) or empirical evidence in support. This paper considers whether the 20 Principles are underpinned by research evidence. It is submitted that advocacy training and the approach to questioning witnesses in the courtroom should take into account the already available research evidence. The authors make recommendations for revision of the training and for a wider review of the approach taken to the handling of witness evidence.
