Age, years of education, and GDS and MMSE scores data presented as mean (SD). Gender and clinical variables presented as n (%).
CTQ = Childhood Trauma Questionnaire; GDS = Geriatric Depression Scale; MMSE = Mini Mental State Examination; SD = standard deviation.
Demographic and clinical profiles were compared between groups with the t test (quantitative variables) and χ2 test (categorical variables).
