The National Alzheimer's Coordinating Center database was used to evaluate mortality risk conferred by sleep, and the Montreal Cognitive Assessment score determined cognitive status. Demographics, sleep disturbances, cognitive status, and comorbid/other neuropsychiatric conditions were examined as predictors of survival time via Cox regression. The sample (N = 31,110) had a median age [interquartile range] of 72 [66, 79] years, MoCA score of 23 [16, 26], and survival time of 106.0 months [104.0,108.0]; 10,278 (33%) died during follow-up; 21% (n = 6461) experienced sleep disturbances.

The surveys included the Measurement of the Five Emotions (MFE) and the Dementia Assessment Sheet for the Community-based Integrated Care System (DASC-21). Item-total reliability and internal consistency reliability were assessed using Spearman's correlation test and Cronbach's alpha coefficient analysis.

The Cronbach's alpha coefficient reached .71, indicating satisfactory internal consistency. There was a negative correlation between the MFE and DASC-21 scores with a correlation coefficient of -.3149. Furthermore, when comparing participants with lower cognitive function (DASC-21 score >26) to those with higher cognitive function, MFE subscale scores in the emotions of \"Sorrow\" and \"Thought\" were significantly lower, suggesting that these particular emotions are related to cognitive impairment. These findings confirmed the reliability and the construct validity of the MFE. <b>Conclusion:</b> The criterion reliability and validity tests provided evidence for the construct validity of the MFE.
