Temporal stability of the Learning Efficiency Test-II for adults

This study examined the temporal stability of the Learning Efficiency Test-II with 101 undergraduate students over a mean test-retest time interval of 19 days. Temporal stability estimates were .79 for the Visual Modality factor score, .75 for the Auditory Modality factor score, and .80 for the Global Memory factor score. A repeated measures analysis of variance for these three factor scores indicated no significant mean differences from Test 1 to Test 2. Slightly lower retest correlations were obtained for each of the 12 subtests, with correlations ranging from .44 to .70. The findings indicate that some subtests are reliable to assess the memory processing of adults over time and also highlight the stability over 19 days of memory processes for intact learners. Other studies with older groups of persons are needed to examine the stability of scores.
