background: the motricity index was used to measure strength in upper and lower extremities after stroke. the weighted score based on the ordinal 6 point scale of medical research council was used to measure maximal isometric muscle strength. there is dearth of articles dealing with the reliability of this method. therefore, the aim of this study was to determine the test retest reliability of ...

background : if an institute is looking for improvement of its learning environment, a reliable and valid assessment tool is needed for measurement of the educational environment .the dundee ready educational environment measure (dreem) has been used in various studies to evaluate the educational environment. however, psychometric evaluations of the instrument seem necessary, for all known vers...

Medical educators attempt to create reliable and valid tests and questionnaires in order to enhance the accuracy of their assessment and evaluations. Validity and reliability are two fundamental elements in the evaluation of a measurement instrument. Instruments can be conventional knowledge, skill or attitude tests, clinical simulations or survey questionnaires. Instruments can measure concept...

Experimental research is increasingly important in developing the understanding of paranoid thinking. An assessment measure of persecutory ideation is necessary for such work. We report the reliability and validity of the first state measure of paranoia: The State Social Paranoia Scale. The items in the measure conform to a recent definition in which persecutory thinking has the 2 elements of f...

A method is described for using Radial Basis Function (RBF) neural networks to generate a certainty factor reliability measure along with the network's normal output. The certainty factor approach is then compared with another technique for measuring RBF reliability, Parzen windows. Both methods are implemented into RBF networks, and the results of using each approach are compared. Advantages a...

A public transport operator’s ability to understand and improve service reliability experienced by passengers depends upon their ability to measure it. Traditionally, largely due to data collection limitations, passengers’ experience of reliability has not been measured directly. As a result, operators often fail to effectively measure, and thus manage, key issue affecting passengers’ perceived...
