TEST-RETEST RELIABILITY OF A NEW FORM OF THE AUDITORY VERBAL-LEARNINGTEST (AVLT)

The equivalence between the original form (Form 1) of the Auditory Ver bal Learning Test (AVLT), and a new form (Form 4) was examined in 51 n ormal adult subjects (20-67 years) of average estimated intelligence w ho were assessed in two separate sessions. Performance on the new form was equivalent to that on the original and most measures on the two t ests showed significant positive correlations. Test-retest reliability of AVLT scores between sessions was also assessed, both globally and separately for Form 1 followed by Form 4 and for the reverse order The most reliable measures on the AVLT were the total number of words lea rned over the five learning trials, (r = .77), and performance on the retention trial of the learning list following the presentation and pe rformance of the distractor list (r = .70). These measures are suffici ently robust for use in clinical serial assessments.
