The authors examined the factor structure of the Knowledge of Memory Aging Questionnaire (KMAQ) [1] using confirmatory factor analysis in a lifespan sample of 933 individuals who ranged in age from 18 to 101. Participants were college students at Louisiana State University and adults from the community enrolled in the Louisiana Healthy Aging Study (LHAS). A two-factor solution was expected, consistent with the normal and pathological memory aging dimensions that comprise the KMAQ. A bi-factor solution with items loading on a general response bias factor and either a normal or pathological knowledge-specific factor showed good model fit. Knowledge scores were correlated with demographic and cognitive performance variables. Implications of these data for clinical settings and research are considered.
作者使用验证性因素分析，对933名年龄在18岁至101岁之间的全生命周期样本个体，检验了记忆老化知识问卷（KMAQ）[1]的因素结构。参与者包括路易斯安那州立大学的大学生以及参与路易斯安那健康老龄化研究（LHAS）的社区成年人。预期会得到一个双因素解决方案，这与构成KMAQ的正常和病理性记忆老化维度一致。一个双因素解决方案，即项目同时加载在一个一般反应偏差因素以及一个正常或病理性知识特定因素上，显示出良好的模型拟合。知识得分与人口统计学和认知表现变量相关。文中还考虑了这些数据对临床环境和研究的意义。
