A short version of the questionnaire of metamemory in adulthood (MIA) in portuguese

ABSTRACT

The aim of this study was to develop a short version of the Metamemory in Adulthood Questionnaire (MIA) in Brazilian Portuguese. The original MIA is an instrument in english composed by 108 items, divided into seven dimensions of metamemory (Strategy, Task, Capacity, Change, Anxiety, Achievement and Locus). Despite of being widely used, the extension of the instrument makes its application impractical in many contexts, reinforcing the need for a short version. A total of 472 participants answered the original full version of the MIA. First, Item Response Theory (IRT) analyses revealed that nine items of the instrument could be excluded due to poor infit and outfit values. After exploratory factor analyses, the 99 items left were judged by five experts that chose the most appropriate items following previously established criteria (factor loading, repetitiveness, bad writing, and temporal/cultural inadequacy). A 39-items version (MIAr) was obtained, with the same factorial structure of the original MIA. The MIAr demonstrated satisfactory internal consistency indexes, as well as evidences of convergent validity and validity based on the response process. The results revealed that the MIAr achieved good psychometric properties, serving as a more parsimonious and practical option for metamemory assessment. (AU)
