The symbiotic experiences of residents with and without dementia co-living in Taiwan's long-term care facilities: a phenomenological study

In Taiwan, residents with and without dementia mostly co-live in long-term care facilities. The behavioral and psychiatric symptoms of dementia residents often pose challenges for others living together. This study explored the symbiotic experiences of residents without dementia co-living with those with dementia in long-term care facilities in Taiwan to present their experiences of living together. This was a cross-sectional descriptive study with a phenomenological design. Semi-structured face-to-face interviews were conducted with 30 residents without dementia from three long-term care institutions in Taiwan. Colaizzi's data processing steps were used for analysis. The analysis of interview transcripts revealed that the experiences of residents who lived with those with dementia were that of a "symbiosis." Three core themes were found: "the impact of co-living," "facing difficulties and coping," and "companionship and reciprocity." This study showed that residents without dementia may be affected by the behavioral and psychiatric symptoms of residents with dementia when co-living in long-term care facilities. However, there are also positive and mutually beneficial interactions between them. By helping people with dementia in their daily lives, residents without dementia feel happy and accomplished and their self-worth is enhanced. Furthermore, residents with dementia have more opportunities for social engagement and co-living interactions. These results can guide long-term care facilities without special care dementia units to support residents without dementia, reduce the interference of the behavioral and psychiatric symptoms of residents with dementia, and promote mutual benefits. However, these findings warrant further investigation.
