OBJECTIVE: To examine the utility of a brief, metacognition questionnaire by examining its association with objective cognitive testing and informant ratings. We hypothesized that the association between self-ratings of change and both outcomes would be greater among individuals without dementia than among those with dementia. METHODS: Participants were 535 persons without dementia and 152 with dementia from the Cache County Memory Study who had completed a metacognition questionnaire, two administrations of the Modified Mini-Mental State Exam (3 MS) and who had data on the Informant Questionnaire of Cognitive Decline in the Elderly (IQCODE). Cronbach's alpha was calculated as a measure of internal consistency of the metacognition questionnaire. Multiple regression was used to examine the relationship between metacognition and 3 MS change. Logistic regression was used to examine the relationship between metacognition and IQCODE ratings (no change vs. worse). RESULTS: Cronbach's alpha was 0.75. Among individuals without dementia, metacognition significantly predicted 3 MS change (p = .027) and IQCODE ratings (OR = 4.0, 95% CI = 1.2-13.8, p = .029), suggesting consistency among measures. For those with dementia, there was a weak, inverse relationship between 3 MS change and metacognition (r = -0.16, p = .056). IQCODE ratings were not significantly associated with metacognition (p = .729). Degree of dementia severity did not modify the relationship between metacognition and either outcome (p > .05). CONCLUSIONS: We demonstrated adequate internal consistency and evidence for validity of a brief metacognition questionnaire. The questionnaire may provide a useful adjunct to memory and functional assessments for assessing anosognosia in elderly populations.
