| Global ECog | 1.40 (0.46) | 1.84 (0.69) | 3.04 (0.77) |
Note. ECog = Everyday Cognition, MCI = Mild Cognitive Impairment, MMSE = Mini-Mental State Examination, NPI = Neuropsychiatric Inventory, SENAS = Spanish English Neuropsychological Assessment Scales. Except for education and gender, variables differed by group (p ≤ .001). All pairwise differences for age, MMSE, SENAS, NPI, and ECog were significant after adjustment for multiple comparisons (p < .001) except for age between Normal and MCI (p = 0.13), and age (p = 0.04), apathy (p = 0.15), and depression (p = 0.43), between MCI and demented individuals.
