한국형 목격자 메타기억척도의 타당화 연구

Abstract

This study validated the Eyewitness Metamemory Scale, developed for the specific context of eyewitness identification, under Korean conditions. Data from 362 participants between the ages of 19 and 60 were subjected to item analysis, factor analysis, convergent and discriminant validity and reliability using the original 35 items. After extraction, 25 items were retained, 10 items were removed and 3 new items were added. Factor analysis confirmed the three-factor structure of the Korean version, which reflected the original scale and achieved a reasonable model fit. Adequate convergent and discriminant validity, as well as internal consistency, supported the reliability and validity of the Korean Eyewitness Metamemory Scale. These findings confirm the utility of the Korean Eyewitness Metamemory Scale as a tool to aid legal decision-making in the Korean criminal identification process and provide a basis for cross-cultural metamemory research in the context of eyewitness identification.
