Performance of the Cognitive Performance Scale of the Resident Assessment Instrument (interRAI) for Detecting Dementia amongst Older Adults in the Community.

The Cognitive Performance Scale (CPS) in the widely used interRAI suite of instruments is of interest to clinicians and policy makers as a potential screening mechanism for detecting dementia. However, there has been little evaluation of the CPS in home care settings. This retrospective diagnostic study included 134 older adults (age ≥ 65) who were discharged from two acute psychogeriatric inpatient units or assessed in two memory clinics. The reference test was a diagnosis of clinical dementia, and the index test was interRAI CPS measured within 90 days of discharge. The overall accuracy of the CPS was good, with an area under the Receiver Operating Characteristic curve of 0.82 (95% CI = 0.75-0.89). The optimal cut point was 1/2, coinciding with the recommended cut point, with good sensitivity (0.90, 95% CI = 0.81-0.96) but poor specificity (0.60, 95% CI = 0.46-0.72). Positive predictive value improved from 0.72 (95% CI = 0.66-0.78) to 0.89 (95% CI = 0.75-0.96) when using a cut point of 2/3 instead of 1/2. If the results of the present study are replicated with more generalisable interRAI samples, older adults with a CPS of 3 or above, but without a formal diagnosis of dementia, should be referred for further cognitive assessment.

Developing a dementia-friendly Christchurch: Perspectives of people with dementia.

AIM: Christchurch, New Zealand has a unique opportunity to potentially rebuild as a dementia-friendly city in the wake of the 2010 and 2011 earthquakes. The present study gathered insights from people with dementia about what would make it possible for them to live better in Christchurch. METHODS: Twenty-six older people living with dementia were interviewed using a semi-structured questionnaire. Interviews were transcribed for thematic analysis. RESULTS: Participants talked about the importance of being connected and engaged; of accommodation from service providers and others in the community and raising awareness of dementia, and attributes of the physical environment requiring consideration in the rebuild. CONCLUSION: The themes that emerged about what people with dementia seek from dementia-friendly communities reinforce previous research, but with an overlay of the difficulties of living in an earthquake-damaged city.

Cultural stereotypes and social representations of elders from Chinese and European perspectives.

Hierarchical cluster analyses of a trait sorting task were used to investigate social representations (and cultural stereotypes) of elderly New Zealanders (NZers) of Chinese and European origin, held by young (mean age = 17) and middle-aged (mean age = 46) NZers from both ethnic groups. Consistent with cultural theories of aging in Chinese societies, organizational features for NZ Chinese were: evaluative simplicity, role-governed representations (e.g., division between socio-emotional and task-oriented elders), little differentiation as a consequence of the ethnicity of elders or age group of subject, and an overall structure dominated by good/bad. NZ Europeans' social representations were more evaluatively complex, had fewer subtypes and more differences as a consequence of target person ethnicity. The Curmudgeon and the Nurturant were the most consensual stereotypes across the 8 cluster analyses (2 subject ethnicity x 2 target ethnicity x 2 subject age group), with the most power to organize stereotypical perceptions of elders across cultural groups. Only the majority group, NZ Europeans, displayed out-group homogeneity effects by creating more categories of elderly Europeans than Chinese. Both ethnic groups held representations of elderly Europeans as higher status in society, and both had more contact with European than Chinese elders outside the family.
