Change From Baseline in Hopkins Verbal Learning Test-Revised (HVLT-R) Score: Total Recall
Hopkins Verbal Learning Test (HVLT) measures performance in verbal memory, learning, and long-term recall in which a list of words is read up to three times. Approximately 20-25 minutes later, a delayed recall trial and a recognition trial are completed. The delayed recall requires free recall of any words remembered. The recognition trial is composed of 24 words, including the 12 target words and 12 false-positives. When scoring the HVLT, the three learning trials are combined to calculate a total recall score (0-36); the delayed recall trial creates the delayed recall score (0 -12); the retention (%) score (0-100%) is calculated by dividing the delayed recall trial by the higher of learning trial 2 or 3; and the recognition discrimination index is comprised by subtracting the total number of false positives from the total number of true positives. A higher score = higher cognition.
