Interviewing cognitively impaired older adults: How useful is a Cognitive Interview?

This research examined whether an Enhanced Cognitive interview (ECI) and a Modified Cognitive Interview (MCI) improved 75- to 96-year-old adults' recall for a video-taped event. Specifically, we examined the effectiveness of these interviews in relation to a Structured Interview (control), and compared the performance of older adults who scored high or low on the Mini-Mental State Examination (MMSE), which is a test to assess cognitive functioning. Participants with low MMSE scores recalled fewer correct details, and were less accurate than those with high scores. Nevertheless, both high and low MMSE groups reported substantially more correct information about Action, Person, Object, and Surrounding details with the MCI and ECI than with the SI. No corresponding increase in the amount of incorrect and confabulated information was found. Furthermore, recall accuracy for both groups was greater with the ECI and MCI than with the Structured Interview. Overall, findings suggest that older individuals, including those with reduced cognitive ability can benefit from the use of Cognitive Interview protocols
