Temporal stability of the Learning Efficiency Test-II

This study's focus was the temporal stability of the Learning Efficiency Test-II for 32 undergraduate volunteers over an average test-retest time interval of 44 days. Correlations and dependent groups t tests were used to examine the consistency of participants' scores across this interval. Analysis indicated high temporal stability for scores on the Visual, Auditory, and Global Memory processing factor, with correlations of .86, .81, and .95, respectively. The temporal stability of participants' scores on the 12 subtests was more variable with statistically significant correlations ranging from .40 to .89. The findings support the reliability of the test as a tool to evaluate the information-processing characteristics of young college students and also show the stability of memory over 6 wk. Expansion to a wider age range of the full population is desirable.
