Background: Green Care Farms (GCFs) are an innovative approach to provide long-term care for people with dementia (PwD). They aim to combine agricultural elements with a home-like environment to support an active daily life for their residents. Characteristics of a long-term care setting not only affect the residents themselves but also their family caregivers (FCs). Their involvement in care is considered valuable. However, research on the involvement of FCs of PwD living in GCFs and their satisfaction with involvement is scarce. Methods: A cross-sectional survey compared the involvement and satisfaction with their involvement of FCs of PwD living in GCFs and regular nursing homes (RNHs). The F-INVOLVEMENT and F-IMPORTANCE balance scale (20 items, 4-point Likert scale) measured both actual involvement and individual importance. Congruence scores were conducted for two groups per item. For FCs who rate this item important (FII) and for FCs who rate this item as not important (FINI). Combining the congruence scores of both groups leads to a total congruence score providing information on satisfaction with family involvement in the facility. Results: Overall, FCs found their involvement important regardless of the type of nursing home. However, FCs at GCFs get statistically significantly more opportunities for involvement than those at RNHs. Also, there was more congruence at GCFs indicating that their involvement is more in line with what they consider to be important regarding their involvement. Conclusion: The findings suggest that the residential care environment can influence the care experience of FCs since opportunities for their involvement align more closely with their preferences for involvement at GCFs than at RNHs. Possibly, GCFs focus more on a relationship-centered care approach, contributing to a more meaningful family involvement. This highlights the potential values of innovative care environments for PwD and their FCs.
