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.
