This study examined the internal and external validity of the Memory Complaint Questionnaire (MAC-Q), a brief measure of subjective memory complaint in people with normal cognitive function.
The Study of Health Outcomes in Aircraft Maintenance Personnel was a retrospective cohort study investigating the association between aircraft fuel tank deseal/reseal activities and health status in Royal Australian Air Force personnel. Cross-sectional comparison tests included measures of executive functioning, psychomotor speed, attention/working memory, new learning/memory, depression, and anxiety. An adjusted regression analysis accounted for confounders including age, dates of posting, rank, education, alcohol use, tobacco use, and affective status.
Eight hundred seventy-nine participants completed the MAC-Q. Although the MAC-Q tested as highly reliable and internally valid, it was highly associated with affective status and was only associated with Digit Symbol Coding after adjustment for depression/anxiety.
The MAC-Q is greatly influenced by affective status but not memory performance. It is probably not useful as a specific screen of memory complaint for general population research.
本研究旨在检验认知功能正常人群中主观记忆主诉的简短测量工具——记忆主诉问卷（MAC-Q）的内部和外部效度。
航空维修人员健康结果研究是一项回顾性队列研究，旨在调查澳大利亚皇家空军人员进行飞机油箱重新密封/重新密封活动与健康状况之间的关系。横断面比较测试包括执行功能、心理运动速度、注意力/工作记忆、新学习/记忆、抑郁和焦虑的测量。调整后的回归分析考虑了混杂因素，包括年龄、任职日期、职级、教育程度、饮酒、吸烟和情感状态。
879 名参与者完成了 MAC-Q。尽管 MAC-Q 测试具有高度可靠性和内部有效性，但它与情感状态高度相关，并且仅在调整抑郁/焦虑后与数字符号编码相关。
MAC-Q 受情感状态影响很大，但不受记忆表现影响。对于一般人群的研究，它可能不是记忆主诉的有用特定筛查工具。
