title: University of Southern California Repeatable Episodic Memory Test.
abstract: The University of Southern California Repeatable Episodic Memory Test (USC-REMT) was developed to provide a brief assay of memory in clinical drug trials where the same subject is tested multiple times over days or weeks. Therefore, it had to be minimally affected by repeated testing. The test also provides a measure of subjective organization, a cognitive strategy that might be sensitive to frontal lobe dysfunction and HIV-related memory deficits. The USC-REMT has seven different lists, each composed of 15 semantically unrelated, high-frequency nouns. The words are presented in a different order on three study-test trials. After each study trial the subject recalls the words in any order. The test takes about 10 min to administer and score. The recall protocol can be scored for (a) global mnemonic efficiency, (b) primary and secondary memory, (c) subjective organization, (d) recall consistency and (e) recall as a function of serial position. We report initial data showing that the test is sensitive to memory decrements. Thirty-six HIV-1 seropositive men, at various stages of illness, recalled significantly fewer words and exhibited less subjective organization than 14 matched controls. The test had no significant practice effects over the first three administrations when separated by several days. The seven alternate lists are essentially equivalent. The USC-REMT appears to complement currently published verbal memory tasks.
