Pre-post differences in caregiver burden (BSFC-s), for three categories of cognitive impairment (n = 271). Cases with a major event during the 6-month intervention phase were excluded. Change scores were computed (the differences in the means of the primary outcomes between t0 and t1). Positive values indicate a decrease in caregiver burden (e.g. + 1 means on average one point less on the burden score after the 6-month intervention phase). MCI (n = 54): Intervention M = 0.16, SD = 3.84, Control M = − 0.45, SD = 3.52. Mild Dementia (n = 110): Intervention M = 1.47, SD = 3.32, Control M = − 0.44, SD = 5.53. Moderate Dementia (n = 107): Intervention M = 0.90, SD = 4.19, Control M = 0.29, SD = 4.32. Significant p-values (<.05) are marked with *
