| Abstract |
Mobility is a key outcome in older patients with cognitive impairment. The de Morton Mobility Index (DEMMI) is an established measure of older people's mobility that is promising for use in older patients with cognitive impairment. The aim of this study was to examine the DEMMI's psychometric properties in older patients with dementia, delirium or other cognitive impairment. This cross-sectional study was performed in a geriatric hospital and includes older acute medical patients with cognitive impairment indicated by a Mini Mental State Examination (MMSE) score ≤ 24 points. A Rasch analysis was performed to check the DEMMI's unidimensionality. Construct validity was assessed by testing 13 hypotheses about expected correlations between the DEMMI and outcome measures of similar or related constructs, and about expected differences of DEMMI scores between groups differing in mobility related characteristics. Administration times were recorded. A sample of 153 patients with mild (MMSE 19-24 points; 63%) and moderate (MMSE: 10-18 points; 37%) cognitive impairment was included (age range: 65-99 years; mean MMSE: 19 ± 4, range: 8-24 points; diagnosis of dementia and delirium: 40% and 18%, respectively). Rasch analysis indicated unidimensionality with an overall fit to the model (P = 0.107). Internal consistency reliability was excellent (Cronbach's alpha = 0.92). Eleven out of 13 (85%) hypotheses on construct validity were confirmed. The DEMMI showed good feasibility, and no adverse events occurred. The mean administration time of 5 min (range: 1-10) was not influenced by the level of cognitive impairment. In contrast to some other comparator instruments, no floor or ceiling effects were evident for the DEMMI. Results indicate sufficient psychometric properties of the DEMMI in older patients with cognitive impairment. German Clinical Trials Register ( DRKS00005591 ). Registered February 2, 2015. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 April 2018.
All research outputs
#5,815,818
of 23,045,021 outputs
Outputs from BMC Geriatrics
#1,352
of 3,242 outputs
Outputs of similar age
#100,703
of 326,557 outputs
Outputs of similar age from BMC Geriatrics
#39
of 60 outputs
Altmetric has tracked 23,045,021 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 3,242 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.4. This one has gotten more attention than average, scoring higher than 54% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 326,557 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
We're also able to compare this research output to 60 others from the same source and published within six weeks on either side of this one. This one is in the 20th percentile – i.e., 20% of its contemporaries scored the same or lower than it.
