In both regressions age, gender and health status of patient and carer were entered into the model, all other variables listed in Table 4 (except for self-rated measures of care dependence patient, burden and well-being carer) were added stepwise using the forward conditional function (p_in = .15 and p_out = .20 were used, considering the limited size of the sample and the explorative nature of the analysis)
