Data presented as mean (standard deviation).

ANOVA = analysis of variance; MAC-Q = Memory Assessment Complaints-Questionnaire; MCI = mild cognitive impairment; MDD = major depressive disorder; MMSE = Mini-Mental State Examination; RAVLT = Rey Auditory Verbal Learning Test; SD = standard deviation.

^*Scores may range from 7 to 35. Higher scores indicate higher memory complaints. Scores ≥ 25 may indicate significant memory complaints.

^†p < 0.01;

^‡p < 0.05;

^§p < 0.001.
