Standardized Β coefficients from adjusted linear regression models of DKAS overall and subscales scores per age groups (reference: 18-30y), contact with person with dementia (compared to no contact, reference), sex (reference: male), and educational level (reference: primary school)
R = Correlation between the observed and predicted DKAS overall and subscales scores
R2 = Proportion of variance in the DKAS scores explained by the four independent variables included in the linear regression model
*, **, *** indicates p values < 0.05, < 0.005, < 0.001, respectively
