Self-report instruments that allow to characterize the frequency of daily memory failures are essential for a comprehensive assessment of memory functioning. In this context, we aimed to provide preliminary evidence of validity and reliability for the European Portuguese adaptation of the Prospective and Retrospective Memory Questionnaire (PRMQ). A total of 1052 healthy participants completed an online survey with the PRMQ. The exploration of the construct validity suggested the tripartite model with a general memory, a prospective memory, and a retrospective memory factors to have the best adjustment to the data. Measurement invariance across age and sex groups was also verified. The questionnaire revealed good convergent validity with a general self-report measure of memory (0.778 < r < 0.853), and satisfactory values of internal consistency (0.779 < Cronbach’s alpha < 0.887) and of test-retest reliability (0.815 < r < 0.852). There were no prominent effects of sex and age in the PRMQ scores. Although the sample encompassed mainly younger and highly educated adults, this study presented the first evidence of validity and reliability for the European Portuguese version of the questionnaire.

葡萄牙年轻人的主观记忆抱怨：前瞻性和回顾性记忆问卷改编的贡献

自我报告工具可以表征每日记忆失败的频率，对于全面评估记忆功能至关重要。在此背景下，我们旨在为欧洲葡萄牙语改编的前瞻性和回顾性记忆问卷 (PRMQ) 提供有效性和可靠性的初步证据。共有 1052 名健康参与者通过 PRMQ 完成了在线调查。构念效度的探索表明三方模型具有一般记忆、前瞻记忆和回顾性记忆因素，可以对数据进行最佳调整。还验证了跨年龄和性别组的测量不变性。问卷显示了良好的收敛效度，一般自我报告的记忆测量（0.778 < r < 0.853），内部一致性（0.779 < Cronbach's alpha < 0.887）和重测信度（0.815 < r < 0.852）的令人满意的值。性别和年龄在 PRMQ 分数中没有显着影响。虽然样本主要包括年轻和受过高等教育的成年人，但这项研究首次提供了欧洲葡萄牙语版问卷的有效性和可靠性证据。
