Reported communication challenges for adult witnesses with intellectual disabilities giving evidence in court

Communication plays a key role in a witness's ability to give evidence and participate in the court process. Adults with intellectual disabilities (ID) can be negatively impacted by communication difficulties such as: limitations in recall abilities; suggestibility to leading questions; difficult question styles used by advocates; and unfamiliar language used within the court setting. Most research carried out on communication challenges for adults with ID, when giving evidence, has involved participants in psychology-based experimental methodology. In this study 19 court reports assessing actual witnesses (complainants and defendants) with ID, written by Registered Intermediaries in Northern Ireland, were analysed. A wide range of communication difficulties were identified for the adult witnesses. Difficulties resulting from communication used by their communication partner (typically the advocate in a court setting) were also described. A rich model of the challenges for both partners, in giving evidence and in cross-examination, is presented, extending previous research. This study highlights the need for research within UK courts to assess: how witnesses with ID are being questioned; the effectiveness of changes made to the court process to enhance communication; the impact of the court process and environment on communication and alternative question styles for advocates to use.
