Correlation between the Short Version of Informant Questionnaire on Cognitive Decline in the Elderly and Rey Auditory Verbal Learning Test in an Outpatient Memory Clinic

Eighty-seven participants, 70.1% women, with a mean age of 78.08 years (SD 6.391) and median of 4 years of education (IQR 8) were included. The items 1, 6 and 14 of IQCODE-SV-BR were the only ones that had significant correlation to all RAVLT scores. Both items 1 and 14 had a mean rho of -.33, Item 1 (Min -0.28 - Max -.387), item 14 (Min -0.24 - Max -.42), and item 6 a mean rho of -.26 (Min -.24 - Max -.31). Only item 14 had a moderate inverse correlation, which was to A7 score. All other inverse correlations were significant, but only weak. (Table 1) CONCLUSION: The IQCODE-SV-BR items 1 ("Remembering things about family and friends e.g. occupations, birthdays, addresses"), 6 ("Remembering where things are usually kept") and 14 ("Handling financial matters e.g. the pension, dealing with the bank") had a significant negative, but weak correlation with RAVLT scores. This exploratory study identified these three items as the most correlated measures with an objective assessment of episodic memory. Further research with larger samples may clarify whether an even shorter version of the IQCODE-SV-BR outperforms the full version in assessing Amnestic Mild Cognitive Impairment or typical ADD.
