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.

Investigative Interviewing of Aboriginal Children in Cases of Suspected Sexual Abuse.

This study examined the investigative interviewing of Australian Aboriginal children in cases of alleged sexual abuse, with a focus on three commonly included components of interview protocols: ground rules, practice narrative, and substantive phase. Analysis of 70 field transcripts revealed that the overall delivery and practice of ground rules at the beginning of the interview was positively associated with the spontaneous usage of rules in children's narratives of abuse. When specifically examining the "don't know" rule, however, only practice had an effect of children's usage of the rule (as opposed to simple delivery or no delivery at all). Children spoke more words overall, and interviewers used more open-ended prompts during the substantive phase when the interviews contained a practice narrative. Children most often disclosed sexual abuse in response to an open-ended prompt; however, they produced the most words in response to suggestive prompts. This article concludes with a discussion of the effectiveness of ground rules, practice narratives, and questioning with Aboriginal children.
