Background: Cultural differences in how the symptoms, causes, consequences, and treatments of dementia are understood and interpreted by South Asian people are a commonly expressed reason for late- or nonuse of mental health and care services. However, systematic collection of information on South Asian perceptions of dementia is hindered by a lack of appropriate instrumentation., Objectives: To produce a shortened version of the Barts Explanatory Model Inventory for Dementia (BEMI-D) schedule., Methods: A two stage item reduction approach was employed first using multidimensional scaling categorizing items as core, intermediate, or outlier. Then, item review was undertaken using three criteria: literature importance, clinical face validity, and sub-group prevalence. The analysis followed a nonmetric multidimensional scaling method based on a two-way proximity matrix., Results: The original BEMI-D had 197 items allocated to four checklists: symptoms, causes, consequences, and treatments. The two stage item reduction approach resulted in the removal of 75 items. These reductions were achieved across all four checklists in relatively equal proportions. There was no evidence of substantive content loss in the revised schedule. The reduced version of the schedule comprises 122 items., Conclusions: A condensed version of the BEMI-D is more efficient as an assessment schedule that captures the culturally diverse perceptions of memory problems for South Asians offering a balanced trade-off between feasibility of use and content validity., (© 2020 John Wiley & Sons Ltd.)

Background: South Asian older adults are represented less frequently in mainstream mental health services or those for people with dementia. This study aimed to explore in detail the perceptions of dementia (symptoms, causes, consequences, treatments) held by South Asians and to discern how these understandings vary by age and by the self-recognition of memory problems, as these influence help-seeking behaviour., Methods: Participants were allocated to three groups: younger adults; older adults; and older adults with subjective memory problems. They completed the semi-structured Barts Explanatory Model Inventory for Dementia schedule, whilst older adults also completed measures of cognition (MMSE), and depression (GDS). Interviews were conducted in English, Gujarati or Urdu., Results: Groups were similar in identifying unusual forgetting and confusion as the most frequent symptoms; stress and age as the most frequent causes; and talking to your GP/nurse, taking medication, and talking to family and friends as the most frequent treatments. Younger adults more often knew about risk factors and reported practical consequences more than older adults. Older adults with subjective memory problems were more likely to describe sleep related problems or symptoms commonly associated with depression. They more often cited as causes of dementia lack of sleep, side effects of medication and medical reasons, and mentioned religion as a means to cope., Conclusions: Findings highlight variability in perceptions of dementia across the South Asian Community and identify specific areas where dementia awareness could be raised in South Asian sub-groups to improve timely diagnosis, treatment outcomes and service access.

Objectives: To examine the relative importance of different home support attributes from the perspective of carers of people with later-stage dementia., Method: Preferences from 100 carers, recruited through carers' organisations, were assessed with a Discrete Choice Experiment (DCE) survey, administered online and by paper questionnaire. Attributes were informed by an evidence synthesis and lay consultations. A conditional logit model was used to estimate preference weights for the attributes within a home support 'package'., Results: The most preferred attributes were 'respite care, available regularly to fit your needs' (coefficient 1.29, p = < 0.001) and 'home care provided regularly for as long as needed' (coefficient 0.93, p = < 0.001). Cost had a significant effect with lower cost packages preferred. Findings were similar regardless of the method of administration, with respite care considered to be the most important attribute for all carers. Carers reported that completing the DCE had been a positive experience; however, feedback was mixed overall., Conclusions: These carer preferences concur with emerging evidence on home support interventions for dementia. Respite care, home care and training on managing difficulties provided at home are important components. Carers' preferences revealed the daily challenges of caring for individuals with later stage dementia and the need for tailored and specialised home support.
