PWD person/people with dementia, ADL activities of daily living, iADL instrumental activities of daily living. ∆ = change t12-t0. a = considered for the regression model according to Pearlin‘s stress process model. b variable congruent with Pearlin’s stress process model included in the regression model as predictor due to significant correlation. c variable added to the regression model as predictor due to methodological considerations. Correlation coefficients (r) used: Pearson for interval scale variables, Spearman for ordinal scale variables. Bold = significant on the level p < .05
