Cognition And Its Association With The Factors Of The Euro-D: Suffering And Motivation. Findings From Share Wave 6

ObjectiveThe aims of this study were (1) to analyse the relationship between cognition and clinical and sociodemographic variables, (2) to explore the relationship between cognitive tests and factors of EURO-D depression scale (Suffering and Motivation), and (3) to determine the relevance of cognition with respect to clinical and sociodemographic variables in the scores of the EURO-D factors.Method: About 63 755 participants in the Survey of Health. Ageing and Retirement in Europe (SHARE) Wave 6 (2015) were included. Instruments are as follows: the SHARE study, the EURO-D scale, and cognitive tests. Bivariate, correlation, and multiple linear regression analyses were performed.Results: In the regression analysis with cognition, the variables associated with poor cognition were higher age (beta =.29), lower educational level (beta = -.26), economic difficulties (beta =.17), and depression (beta =.10). The correlation between cognition and EURO-D factors was weak in Suffering (r = -0.139) and moderate in Motivation r = -0.382). In the regression analysis with the EURO-D, loneliness, poor self-perceived physical health, female gender, and low cognition were associated with higher depression levels. The main differences in the predictor variables of each factor were cognition (Motivation = -0.248, P < .001; Suffering = 0.002, P = .648) and the female sex (Motivation = 0.015, P<.001, Suffering = 0.175. P <.001).Conclusions: In the EURO-D depression scale, poor cognition was associated with higher scores in the Motivation factor only, while the female gender presented higher scores in the Suffering factor.
