Linguistic and ethnocultural diversity in long-term residential care is a growing trend in many urban settings. When long-term care staff and residents do not share the same language or ethnocultural background, the quality of their communication and care are jeopardized. There is very little research addressing how staff and residents communicate when they experience a mismatch in their language and ethnocultural backgrounds. Thus, the goals of the present study were to 1) document the verbal and nonverbal behaviours used by staff and residents in diverse interactions, and 2) identify and account for behaviours that either promoted or detracted from positive communication by drawing on principles from 'Communication Accommodation Theory'. Two long-term care facilities in British Columbia Canada were selected due to the diverse linguistic and ethnocultural backgrounds of their staff and residents. Twenty-seven staff and 27 residents consented to being video-recorded during routine activities (e.g., mealtimes, recreational activities). The recorded observations were transcribed, translated, and coded using qualitative descriptive and interpretive analyses. A number of verbal and nonverbal behaviours were identified and interpreted in relation to whether they promoted or detracted from positive communication. The findings point to considering a variety of proactive strategies that staff and administrators could employ to effectively accommodate to language and ethnocultural diversity in long-term care practice.

Dementia has been understood primarily as a biomedical phenomenon with a trajectory of irrevocable decline related to neurodegenerative changes. However, growing evidence suggests that the performance and behaviour of persons with dementia are not exclusively determined by neuropathology but are also influenced by personal histories, social interactions and social contexts. This evidence shifts attention from the disease process to the need for a more in-depth understanding of the place of personhood in dementia care. Despite its intuitive appeal however, there is limited empirical research grounding this approach to care. This article articulates a framework for organizing research in this area that is based on a critical review and synthesis of research. It encompasses three interrelated and intersecting domains of inquiry: the subjective experience of the person with dementia, the immediate interactional environment and the broader socio-cultural context. Each domain encapsulates a unique but interrelated dimension of a person-centred approach to dementia care. de men tia d e m e n t i a

This critical constructionist case study of 'Leonard,' a man with frontotemporal dementia living on a special care unit predominantly populated by people with Alzheimer's disease and related dementias, explores how healthy others' perceptions of the prevailing physical and psychosocial environment were influenced by Leonard's behaviour which, in turn, was influenced by people's perceptions of him as a 'problem'. Data were obtained through participant observations, individual interviews with staff and residents, and focus groups with family members and nursing staff. Leonard's 'needs-driven dementia-compromised' behaviours are not recognized as such by many of the healthy others with whom he co-creates his psychosocial environment; rather he is constructed as deviant, which undermines his selfhood as well as his quality of life. Education of staff and family members as well as broad organizational change is needed to address the issues underlying the problems for which Leonard is blamed but instead arise largely from the environment within which Leonard is situated.Keywords critical constructionist methodology, frontotemporal dementia, long-term care, needs-driven dementia-compromised behaviour model, physical and psychosocial environments -special care units
