Abstract:
OBJECTIVES: The present study was designed to develop KAVLT (Korean Auditory Verbal Learning Test)and to examine its reliability and validity. The KAVLT is a modified Korean version of RAVLT (Rey Auditory Verbal Learning Test) The KAVLT assesses immediate supraspan memory, registration, retention, retrieval, recognition, learning strategy, and interference effect. METHODS: Final version of KAVLT was developed through preliminary trials. The KAVLT was administered to 75 normal healthy adults and 30 organic brain syndrome patients. Twenty-five normal controls were retested 3 weeks after the first trial to examine the test-retest reliability. The scores of basic and combined indices of KAVLT were compared between normal controls and patients. Factor analysis was done to investigate the construct validity. RESULTS: Significant correlations were found between the test-retest scores of most of the basic indices. Discriminant validity which differentiates organic brain syndrome patients from normal controls was excellent. In order to accomplish the structure analysis of the KAVLT, different sets of scores were submitted to factor analysis procedure. Factor analysis of KAVLT basic indices revealed 2 factors, 'aquisition' and 'retention'. In the factor analysis of KAVLT's basic and combined indices, 4 factors emerged: 'general learning', 'retroactive interference', 'proactive interference', and 'primacy/recency effect'. CONCLUSION: The newly developed KAVLT was found to be a reliable and valid tool for evaluating multifactorial assesment of verbal memory and learning in Korean subjects.
