In order to better understand the test-retest reliability of the ImPACT test battery, 25 undergraduate students completed two ImPACT tests across a time frame of 4 weeks between assessments. . Dependent sample t-tests revealed significant improvement on only Visual Motor Speed composite scores. . ImPACT test may result in significant . Specifically, higher ICCs (0.38 to 0.85) were reported for the ImPACT composite visual motor speed and composite reaction time scores and lower ICCs (0.23 to 0.64) for composite visual and verbal memory. 7,10,11 The highest ICC values were for the version of ImPACT (0.62 to 0.85), using a 1-year test-retest interval, in participants 13 to .You’ll be given an ImPACT computer test so we can see how your brain is working after you’ve had a concussion. You need to be at least 12 years old to take this 30-minute test. The test studies your memory and measures: How long you can focus on a task; How fast your brain is working; How fast you can respondThe ImPACT composite's validity was further investigated using exploratory factor analysis (EFA). Six principal components were termed processing speed, visual memory, verbal memory, attention & working memory, and verbal fluency, based upon traditional test loadings, and a sixth loaded only on the ImPACT Reaction Time composite.
Most of the participants were administered the baseline form (Form 1) on ImPACT; however, and unknown number received Forms 2-4 at different administrations. ImPACT provides 4 composite test scores: Verbal Memory, Visual Memory, Visual-Motor Speed, and Reaction Time, as well as a Total Symptom Scale Score.The visual-motor speed (VMS) component of ImPACT is commonly used for determining visual-motor deficits and has been shown to be the most reliable of the ImPACT composite scores. In addition, the reaction time (RT) and visual memory (VIS) composite scores address visual processing and motor speed. . ImPact test-retest reliability: reliably .
ImPACT is made up of three parts: sport & health history, current symptoms & conditions, and the neurocognitive test portion. Six subtests make up the neurocognitive portion, and raw scores from those six sections contribute to four composite scores (verbal memory composite, visual memory composite, visual motor speed, and reaction time).
The ImPACT test reports four composite scores including verbal memory, visual memory, visual-motor processing speed, and reaction time . As concussion results in a constellation of signs and symptoms that affect cerebral functioning [ 1 ], a clear understanding of the validity literature germane to diagnosis, prognosis, and management of . A baseline ImPACT comparison of student-athletes tested in English and Mandarin reflected a small to medium group difference for the visual motor speed composite score (d = 0.37), with higher performances by the participants tested in Mandarin. 21 Among the ImPACT neurocognitive composite scores, visual motor speed appears to differ most .The distracter is a choice reaction time test and performance on this measure is incorporated into other aspects of ImPACT (e.g., visual motor processing speed and reaction time). . Measures working memory and visual-motor response speed; First, the test taker is allowed to practice a distracter task that consists of 25 numbered buttons on a . In addition to visual motor response speed, however, the ImPACT Visual Motor Speed composite score is described as evaluating learning and memory and visual processing (ImPACT Technical Manual, Citation 2012; see also Table 1). With respect to its convergence with traditional measures of visual memory and learning, in the MTMM, weak but .
ImPACT is the most commonly utilized computerized neurocognitive assessment for the clinical management of sport concussion. The cognitive composite scores that ImPACT currently reports include Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, and Impulse Control. However, exploratory factor analytic studies report that two or more factors may better . The Three Letters Average Counted Correctly contributes to Visual Motor Speed composite for the ImPACT Online Version. Symbol Match Average RT contributes to the RT Composite, and the memory performance on Three Letters and Symbol Match contributes to the Verbal Memory composite score. . is consistent with 45- and 50-day test–retest data .Test Version composite scores Memory composite (verbal) Memory composite (visual) Visual motor speed composite time composite Impu Ise control com site Total S m tom Score Cognitive Efficiency Index: Clinical Report Pcst.lnjury 11/20/2012 09/18/2013 English 2.1 Basahne 011212013 Post-lnjury 1 09/27/2013 09/25,2013 English Post-injury 2 09/30/2013
test loadings, and a sixth loaded only on the ImPACT Reaction Time composite. EFA indicated content validity of moderate strength for the Visual Motor Speed and Visual Memory composites, but revealed problems with specificity for the other composites. Based upon the present findings, validity problems render the interpret-The Pearson test-retest correlation coefficients for the composite scores were as follows: Verbal Memory = .70, Visual Memory = .67, Reaction Time = .79, Processing Speed = .86, Post-concussion Scale = .65. These coefficients are used in the calculation of the RCI, which are referred to as r12 test-retest coefficients.
Both versions of ImPACT offer 6 test modules to produce 4 composite scores: verbal memory, visual memory, visual motor speed, and reaction time. Higher composite scores on visual and verbal memory and visual motor speed and a lower score on reaction time indicate better performance. ImPACT consists of four primary composite scores including two memory composites (verbal memory and visual memory) and two speed composites (visual motor speed and reaction time) that are derived .Speed and Memory z-scores were calculated, and test-retest reliability (using intra-class correlation coefficients) at 1 month (0.88/0.81), 1 year (0.85/0.75), and 2 years (0.76/0.74) were higher than published data using Composite scores. Speed and Memory scores yielded 89% sensitivity and 70% specificity, which was higher than composites (80% .
Predictor variables included sex, loss of consciousness, history of ocular disorder, history of concussion, performance on visual motor speed composite, visual motion sensitivity symptom . At the time it was introduced (Version 1.2), ImPACT generated only three composites scores for use in clinical interpretation; Memory (i.e., Verbal Memory), Reaction Time, and Processing/Visual Motor Speed, along with Impulse Control (for evaluating test validity); Visual Memory was introduced as a composite score in Version 2.0, but for non .
What are the reliable change indices (RCIs) for the ImPACT
ImPACT Verbal and Visual Memory Composite scores correlate with both the HVLT and BVMT-R, as well as the SDMT Memory Sub-scales (significant at P<.001) which represent measures of verbal and visual memory. ImPACT Motor Speed and Reaction Time Composite Score both correlate with the SDMT Total Correct Subscales, which represents a measure of .The visual-motor speed (VMS) component of ImPACT® is commonly used for determining visual-motor deficits. Notably, VMS has been shown to be the most reliable of the ImPACT® composite scores [18]. The other composite scores that address visual processing and motor speed are reaction time (RT) and visual memory (VIS). These scores (VMS, RT,
