Assessing the quality of a tool used to measure function and disability in older adults: A systematic planned out, orderly, regular review

Review go over, check Question

What is the quality of the Late-Life Function and Disability Instrument, a popular tool to measure outcomes for older adults?


Researchers often use Late-Life Function and Disability Instrument tool, device (LLFDI) to assess review, sum up, evaluate, to determine figure out, decide, find out, test value, find functional limitations and disability in studies with older adults. This review go over, check evaluates the evidence supporting the use of the LLFDI. Accurate true, right, correct assessments are needed to evaluate interventions and improve access to health care services for older adults.

Search Date

The search included studies published before January 28, 2013.

Study Characteristics

The review go over, check includes studies published in English that report results based on the original version of the LLFDI. The study population had to include older adults who live in communities, rather than institutions (such as long-term for a long time, over a long period of time care facilities). The average age of each study?s sample had to be greater than 60 years old. Seventy-one studies including 17,301 older adults met the inclusion criteria. Most studies took place in the United States.

Key Results

There is strong evidence to support the LLFDI?s construct make, build validity truth, proof and sensitivity to change. Construct make, build validity truth, proof means that a test is measuring what it is trying to measure. Sensitivity to change means that the test can capture changes in a person?s health status. state, condition The Function component part, section of the LLFDI has high test-retest reliability, meaning that the results are consistent stays the same when participants take the same test at different points in time. The Disability component part, section has lower test-retest reliability. Further work is needed to determine figure out, decide, find out, test the LLFDI?s predictive validity truth, proof (how well the test predicts some other variable measured at a later date) and to understand know, to get how big a change in the LLFDI is needed to be clinically meaningful.

Use of Statistics

The review go over, check presents correlation coefficients on a variety of properties. When possible, the authors calculate a Cohen?s effect result, cause size, which is the average change divided by the standard deviation of the baseline value. They classify effects as small, moderate, and large based on these effect result, cause sizes.

Quality of Evidence

The authors state say, tell, condition that a quality assessment was beyond the scope of the review. go over, check However, few studies included in the review go over, check were specifically designed to assess review, sum up, evaluate, to determine figure out, decide, find out, test value, find the LLFDI, so the authors could not perform do, carry out, act a formal meta-analysis. In addition, this review go over, check only applies to the original version of the LLFDI.
