Adults with communication impairment are vulnerable to abuse and are over-represented as victims in the criminal justice system. Investigative interviewers rely largely on verbal accounts to establish whether a criminal offence occurred, and therefore the way these accounts are elicited is paramount. To date, little research has evaluated whether current interviewing protocols are appropriate for eliciting accurate and detailed information from adults with communication impairment. The present study explored this issue through qualitative interviews with professionals from various disciplines. Specifically, professionals (N = 22) who had extensive experience in interviewing, disability advocacy, and cognitive and communication impairment reflected on current recommended practice and how it could potentially improve. The results indicated widespread support for the current (open questioning) approach, although the professionals perceived that additional verbal and visual scaffolding could potentially enhance the amount of detail obtained without compromising accuracy. Suggestions for interview protocol modifications and future research are discussed.

有交流障碍的成年人容易受到虐待，并且在刑事司法系统中被过度代表为受害者。调查访问员主要依靠口头陈述来确定是否发生了刑事犯罪，因此引出这些陈述的方式至关重要。迄今为止，很少有研究评估当前的访谈协议是否适合从有沟通障碍的成年人那里获取准确和详细的信息。本研究通过对来自不同学科的专业人士的定性访谈来探讨这个问题。具体来说，专业人士（N = 22) 谁在访谈、残疾宣传以及认知和沟通障碍方面具有丰富的经验，反映了当前推荐的做法及其可能如何改进。结果表明对当前（开放式提问）方法的广泛支持，尽管专业人士认为额外的口头和视觉支架可能会在不影响准确性的情况下增加获得的细节量。讨论了对访谈协议修改和未来研究的建议。
