Calculating the test-retest reliability co-efficient from normative retest data for determining reliable change.
This letter is essentially an addendum to Hinton-Bayre (2010), where a comparison of several models of reliable change (RC) was made. RC statistics have been developed to assess whether an individual has demonstrated statistically significant change over time or following an intervening event or treatment. Popular settings for this include sports-related concussion, brain surgery, and cardiac s...
متن کاملA basis for analyzing test-retest reliability.
Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complet~ analysis than does the conventional one; Spearman’s contention is verified that the conventional approach--which was formulated by Yule--introduces unnecessary hypotheses. It is emph...
متن کاملTest-retest reliability of the Dynavision apparatus.
The Dynavision apparatus was developed to measure and train a number of psychomotor s u s , including visual scanning, peripheral visual awareness, and visuomotor reaction time (Performance Enterprises, 1992). Although several rehabilitation and human performance centers currently use the apparatus in occupational therapy and sport-related training, no reports of reliability have been published...
متن کاملTest-Retest Reliability of the Digijump Machine
Repetitive jumping has been identified as a possible exercise modality able to provide sufficient stimulus to improve bone health. However, it is necessary to establish whether repetitive jumping can elicit a consistent physiological response with the ablity to monitor work rate. The purpose of this investigation was to determine the stability reliability of the Digijump device for the commonly...
متن کاملTest-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects
Abstract Background: Postural instability has been identified as a potential precursor of falls in elderly subjects. Postural stability in quiet stance is commonly assessed with center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure (COP) measures in the elderly subjects. Met...
