Abstract

The Metamemory in Adulthood (MIA) questionnaire, which was designed to investigate the multidimensional representation of metamemory in North Americans (Dixon & Hultsch, 1983; Dixon et al, 1988), has been one of the most widely and frequently utilized questionnaires in the world. This study aimed to amend the current Japanese MIA (Kinjo et al., 2008) and develop a new short version that is applicable to both young and older adults and to both sexes. Japanese from two age groups participated in this study: young adults (N=240, M age=20.6 years old) and older adults (N=268, M age=70.2). The results of factor analyses showed that six of the original seven subscales (Anxiety, Capacity, Change, Locus, Strategy, and Task) were identified for each age group, the merged age groups, and each sex. Based on this factorial structure, 92 items on the MIA (excluding 16 items of the MIA Achievement subscale from the total of 108 items) could be reduced to 44 items without loss of the factorial structure or lowering the internal consistencies of the subscales for both age groups and both sexes.
