  1. n = 269 cases; 351 cases of the total sample less 82 care-receivers who died at home.
  2. aChi2 = 41.36 (p < .001); Nagelkerke’s R2 = .283 (none of the 6 potential predictors had to be excluded from the multivariate analysis due to multicollinearity).
  3. bFamily caregiver and care-receiver with dementia share a flat or house.
  4. cScore of the BSFC-s.
  5. dMini-Mental Status Examination.
  6. eUrban region: cities with at least 100,000 citizens; rural region: cities with less than 100,000 citizens and villages.
  7. Other variables were not significantly correlated with institutionalization: study arm (p = .500); sex of family caregiver (p = .527); caregiver spouse yes/no (p = .434); sex of care-receiver with dementia (p = .538); NOSGER subscale “Disturbing behavior” (p = .073); NOSGER subscale “IADL” (p = .257); family caregiver diagnosed with depression yes/no (p = .696); care level yes/no (p = .249); Barthel Index (p = .737); caregiving tasks at night yes/no (p = .532); average hours of daily care (p = .389).
