Traditional methods to assess changes in dietary intake, for example food frequency questionnaires or 24-hour dietary recalls, are often not practical: they are lengthy, expensive, and unsuitable for telephone administration. This article describes the development and evaluation of an approach to the ...
Objectives To investigate instrument validity and reliability of a choice response time (CRT) test for the lower extremities in subjects with incomplete spinal cord injury (iSCI). CRT in subjects with iSCI is hypothesized to be increased because of, for example, muscle weakness or increased ...
Each item has four response options that correspond to four different outcome states (ideal state (coded as 3 in the analysis), no unmet needs (coded as 2), some unmet needs (coded as 1), and high-level of unmet needs (coded as 0)). For example for food and drink, the response ...
Reliability is a measure of the stability or consistency of test scores. You can also think of it as the ability for a test or research findings to be repeatable. For example, a medical thermometer is a reliable tool that would measure the correct temperature each time it is used. In the...
Reliability Definition: Reliability is the consistency of your measurement, or the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects. In short, it is the repeatability of your measurement. A measure is considered reliable if...

(Campbell & Fiske, 1959). This is difficult when items for a scale are measured within a single instrument such as a survey. With a large number of documents collected from a number of sources, this issue is less problematic: items loading on a single latent factor come from multiple ...
with regard to the expected functionality of the instrument. If an instrument aims to measure functional mobility in older people, the content validity of the OM is a measure of how well the constituent parts reflect the aim of the instrument, which should be clearly stated in the design phase...
