Why the study?
Is a six-test neuropsychological test battery reliable over 7-day and 3-month intervals in older adults serving as normative controls?
Is a six-test neuropsychological test battery reliable over 7-day and 3-month intervals in older adults serving as normative controls?
A six-test neuropsychological test battery demonstrates moderate to excellent test-retest reliability over 3 months, making it appropriate for use in postoperative cognitive dysfunction research.
Supports reliability of this battery for normative controls in POCD research; validation in surgical patients remains needed.
All tests had moderate to excellent test-retest reliability during 7-day (ICC range 0.63 to 0.94; all p < 0.01) and 3-month intervals (ICC range 0.60 to 0.92; all p < 0.01) though confidence intervals of ICC estimates were large throughout. Practice effects apparent at 7 days eased off by 3 months. No substantial differences between computerized and non-computerized tests were observed. We conclude that the present six-test neuropsychological test battery is appropriate for use in POCD research though small sample size of our study needs to be recognized as a limitation.
