The ability of adults with limited expressive language to engage in open-ended interviews about personal experiences.

This study examines how adults with limited expressive language (with average sentences of five words or less) respond to open-ended questions. Participants (n = 49) completed a baseline measure and were then interviewed about a personal experience using exclusively open-ended questions, followed by open-ended and directive questions about a staged event. Their interviews were coded for mean length of utterance (MLU), number of different words and six dimensions of the Narrative Assessment Profile. Descriptively, the participants were able to give some event-related detail in their narratives, but there was wide variability in narrative quality. Correlational and regression analyses indicate that their MLU was stable across contexts. The findings suggest that adults with limited expressive language can provide informative responses to open-ended questions about their experiences, and that their expressive language is likely to show stability across introductory and substantive interview phases.

Professionals' views on how to conduct investigative interviews with adults with limited expressive language.

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.

"She Wanted to Know the Full Story": Children's Perceptions of Open Versus Closed Questions.

The current study explored children's perceptions of open and closed questions in an interview setting. Children aged 7-12 ( n = 83) years watched a short film and were questioned about it by an interviewer who asked only open questions and an interviewer who asked only closed questions (counterbalanced). A third interviewer subsequently invited perceptions of each interview by asking children to compare the interviews on 10 attributes (e.g., length, perceived interviewer interest). Children's comparisons on each of the 10 attributes were analyzed quantitatively and their responses to the follow-up questions underwent thematic analysis. Overall, children tended to find closed questions easier than open questions because they required less thought to answer but felt more listened to and better able to give their stories in response to open questions. Their perceptions frequently matched findings in the literature about the utility of open versus closed questions. The research has implications for interviews with child victims.

Children's use of sexual body part terms in witness interviews about sexual abuse.

For successful prosecution, investigative interviews with child sexual abuse victims need to establish the nature of the alleged offence by determining the body parts that were involved. To date, however, there has been a paucity of research on the extent to which children clearly identify sexual body parts in interviews and how they respond to interviewers' attempts to clarify ambiguous terms. The present study sought to explore children's use of sexual body part terms in field interviews, and their responses to questions aimed at clarifying ambiguous terms. Analyses were conducted on 161 transcripts of field interviews with children aged 4-17 years old, coding for the content of interviewers' questions and of children's responses. Results revealed that many children, even some in their late teens, struggled to provide clear terms for their sexual body parts, either initially, or when asked to provide an alternate term. Questions about body part location or function tended to elicit content appropriate responses in children, irrespective of age. The study discusses the capacity (or willingness) of children to provide clear body part terms in witness interviews and the utility of particular questions. The findings imply a need for caution when following up on the meaning of terms or asking particular clarifying questions, and highlight the importance of childhood education around body parts.
