Memory failures are common in daily life. However, these failures could indicate cognitive problems, mainly in elders. This study presents the translation and adaptation of the Prospective and Retrospective Memory Questionnaire (PRMQ) to Portuguese. The questionnaire measures prospective and retrospective self-report memory failures through 16 items. There were 642 participants aged between 16 and 81 years recruited in a university and in community groups. The exploratory factor analysis revealed the construct validity only for eight items. So, it was reconsidered two of the original 16 items that showed acceptable factorial load and tested a questionnaire of 10 items. Convergent and concurrent validity was tested in a sample of 38 participants aged around 69 years, through the Elders' Subjective Perception of Memory Complaints Questionnaire (MAC-Q). As a result the reduced PRMQ with 10 items showed both validity and confidence (a = 0,80). At this point the questionnaire seems promising for research using.
