Test Retest Reliability

Background: Vision tests are increasingly being suggested for use in concussion management and baseline testing. Concussions, however, often occur months after baseline testing and reliability studies generally examine intervals limited to days or one week. Therefore, our objective was to determine the one-year test-retest reliability of these tests. Methods: We assessed one-year test-retest reliability of ten vision tests in elite Canadian athletes followed by the Institut National du Sport du Quebec. We included athletes who completed two baseline (preseason) annual evaluations by one clinician within 365±30 days. We excluded athletes with any concussion or vision training in between the annual evaluations or presented with any factor that is believed to affect the tests (e.g. migraines, etc.). Data were collected from clinical charts. We evaluated test-retest reliability using Intraclass Correlation Coefficient (ICC) and 95% limits of agreement (LoA). Results: We examined nine female and seven male athletes with a mean age of 22.7 (SD 4.5) years. Among the vision tests, we observed excellent test-retest reliability in Positive Fusional Vergence at 30cm (ICC=0.93) but this dropped to 0.55 when an outlier was excluded in a sensitivity analysis. There was good to moderate reliability in Negative Fusional Vergence at 30cm (ICC=0.78), Phoria at 30cm (ICC=0.68), Near Point of Convergence break (ICC=0.65) and Saccade (ICC=0.56). The ICC for Positive Fusional Vergence at 3m (ICC=0.56) also decreased to 0.21 after removing one outlier. We found poor reliability in Near Point of Convergence (ICC=0.47), Gross Stereoscopic Acuity (ICC=0.03) and Negative Fusional Vergence at 3m (ICC=0.0). ICC for Phoria at 3m was not appropriate because scores were identical in 14/16 athletes. 95% LoA of the majority of tests were ±40% to ±90%. Conclusions: Four tests had moderate one-year test-retest reliability. The remaining tests had poor reliability. The tests would therefore be useful only if concussion has a moderate-large effect on scores.

Abstract Objective The mini-BESTest is a balance measure for assessment of the underlying physiological systems for balance control in adults. Evaluations of test–retest reliability of the mini-BESTest in larger samples of people with multiple sclerosis (MS) are lacking. The purpose of this study was to investigate test–retest reliability of the mini-BESTest total and section sum scores and individual items in people with mild to moderate overall MS disability. Methods This study used a test–retest design in a movement laboratory setting. Fifty-four people with mild to moderate overall MS disability according to the Expanded Disability Status scale (EDSS) were included, with 28 in the mild subgroup (EDSS 2.0–3.5) and 26 in the moderate subgroup (EDSS 4.0–5.5). Test–retest reliability of the mini-BESTest was evaluated by repeated measurements taken 1 week apart. Reliability and measurement error were analyzed. Results Test–retest reliability for the total scores were considered good to excellent, with intraclass correlation coefficients of .88 for the whole sample, .83 for the mild MS subgroup, and .80 for the moderate MS subgroup. Measurement errors were small, with standard error of measurement and minimal detectable change of 1.3 and 3.5, respectively, in mild MS, and 1.7 and 4.7, respectively, in moderate MS. The limits of agreement were − 3.4 and 4.6. Test–retest reliability for the section scores were fair to good or excellent; weighted kappa values ranged from .62 to .83. All items but 1 showed fair to good or excellent test–retest reliability, and percentage agreement ranged from 61% to 100%. Conclusions The mini-BESTest demonstrated good to excellent test–retest reliability and small measurement errors and is recommended for use in people with mild to moderate MS. Impact Knowledge of limits of agreement and minimal detectable change contribute to interpretability of the mini-BESTest total score. The findings of this study enhance the clinical usefulness of the test for evaluation of balance control and for designing individually customized balance training with high precision and accuracy in people with MS.

This study aimed to evaluate the test–retest reliability of soccer skill tests belonging to the F-MARC test battery. To avoid bias during talent identification and development, coaches and scouts should be using reliable tests for assessing soccer-specific skills in young male players. Fifty-two U-14 outfield male soccer players performed F-MARC soccer skill tests on two occasions, separated by 7 days. After familiarization, we administered two trial sessions of five skill tests: speed dribbling, juggling, shooting, passing, and heading. We assessed absolute reliability by expressing the standard error of measurement as a coefficient of variation with 95% limits of agreement, and we assessed relative reliability with the intraclass correlation coefficient and with Pearson’s correlation ( r). The results demonstrated satisfactory relative and absolute reliability for speed dribbling, right foot juggling, short passing, shooting a dead ball right, shooting from a pass, heading in front, and heading right. However, reliability values for left foot juggling, chest-head-foot juggling, head-left-foot-right foot-chest-head juggling, long pass, and shooting a dead ball left tests were not strong enough to suggest their usage by coaches in training or sport scientists in research.

AbstractBackgroundTests of binocular vision (BVTs) and ocular motility are used in concussion assessment and management.PurposeTo determine the one-week test-retest reliability of 9 binocular vision tests (BVTs) and a test of saccades proposed for use in concussion management.Study DesignProspective test-retest.MethodsWe examined the one-week test-retest reliability of 9 BVTs in healthy participants: 3D vision (gross stereoscopic acuity), phoria at 30cm and 3m, ability of eyes to move/fixate in-sync (positive and negative fusional vergence at 30cm and 3m, near point of convergence and near point of convergence – break [i.e. double vision]) and 1 ocular motor test, saccades.ResultsWe tested 10 males and 10 females without concussion and a mean age of 25.5 (4.1) years. The intraclass correlations suggest good reliability for phoria 3m (0.88) and gross stereoscopic acuity (0.86), and moderate reliability for phoria 30cm (0.69), near point of convergence (0.54), positive fusional vergence (0.54) and negative fusional vergence (0.66) at 30cm, and near point of convergence - break (0.64). There was poor reliability for saccades (0.34), and both positive and negative fusional vergence (0.49 and 0.43, respectively) at 3m. Limits of agreement (LoA) were best for saccade (±34%) and worst for phoria 30 cm (±121%) and ranged from ±58% to ±70% for 7 of the 8 other tests. The LoA for phoria at 3m were uninformative because measurements for 18 of 20 participants were identical.ConclusionWe found test-retest reliability of the BVTs and saccades ranging from poor to good in healthy participants, with the majority being moderate.Clinical RelevanceFor these vision tests to be clinically useful, the effect of concussion must have a moderate to large effect on the scores of most of the tests.What is known about the subjectConcussions may affect some parts of visual function1-week test-retest reliability for most visual tests is under-studiedWhat this study adds to existing knowledgeWe provide intra-class coefficients and limits of agreement for 10 different visual function tests commonly conducted by clinicians in patients with concussion.

The present study examined the test–retest reliability of the Ghent University dribbling test and short dribble test in a pediatric population. Fifty-four boys aged 9–14 years (mean ± SD = 11 ± 2 years) undertook the Ghent University and dribbling tests on two occasions separated by 2 weeks. Intraclass correlation coefficients, coefficient of variation, and 95% limits of agreement were conducted for each test. Intraclass correlation coefficients and coefficient of variation indicated good to excellent reliability, and relatively small variability for both dribbling tests. The 95% limits of agreement indicated relatively little bias Ghent University dribbling test for both running alone and running with the ball components, and the Bangsbo and Mohr short dribble test. The results of the present study suggest both dribbling tests examined in the present study demonstrate good reliability and low levels of systematic bias.

ObjectiveThe purpose of this study was to evaluate test-retest reliability and practice effects of the Dynavision D2 in active adolescents.BackgroundFollowing sport-related concussion, assessment of oculomotor function and vision is important. While clinical tests are recommended, computerized devices, such as the Dynavision D2, are emerging as viable tools for vision assessment. As with all concussion assessments, understanding test-retest reliability and susceptibility to practice effects is important for appropriate interpretation of serial assessments post-injury.Design/methodsParticipants included 20 female adolescents (age = 16.6 ± 1.10 years, mass = 62.0 ± 5.9 kg, height = 169.2 ± 5.1 cm). Participants completed 2 test sessions 1 week apart using the Dynavision D2. The Dynavision D2 includes a one-minute drill task where a single light illuminates, and participants hit the light as quickly as possible, completing 3 drills per trial. Participants completed 3 trials during the first session and 2 during the second. Independent variables were day (day 1, day 2) and drills (15 drills). Dependent variables were the number of hits per minute (Hits/min) and average reaction time (AvgRT). Within-day and between-day test-retest reliabilities were analyzed using two-way random effects intraclass correlation coefficients for consistency. Practice effects were analyzed with repeated measures analysis of variance and Helmert contrasts (p = 0=.05).ResultsModerate-to-strong reliability was demonstrated for Hits/min (within-day 1 [ICC = 0.74; 95% CI: 0.53, 0.87]; within-day 2 [ICC = 0.91; 95% CI. 77.97]; between-days [ICC = 0.86; 95% CI. 65.95]). Moderate-to-strong reliability was demonstrated for AvgRT (within-day 1 [ICC = 0.70, 95% CI. 48.86], within-day 2 [ICC = 0.92; 95% CI. 78.97]; between-days [ICC = 0.85; 95% CI: 0.64.94]). Practice effects were noted for Hits/Min (p = 0.001) and AvgRT (p < 0.001). Helmert contrasts suggested that the practice effect plateaued at drill 11 for Hits/min and drill 12 for AvgRT.ConclusionsModerate-to-excellent test-retest reliability was found for the one-minute task drill with better reliability noted on day 2 and between days, compared to day 1. This task is susceptible to practice effects, highlighting the need for familiarization or practice trials prior to documenting patient scores.

Test Retest Reliability

Background and PurposeTo assess the psychometric properties of the PAM13 Brazilian-Portuguese (PAM13-B) among outpatients with chronic diseases.Methods513 adults participated, diagnosed with a chronic disease for more than 6 months, under outpatient monitoring. Reliability was tested using internal consistency and test-retest reliability. Construct validity was verified through different techniques (correlation between activation and self-esteem measures, anxiety, depression and health status), known-groups validity and dimensionality by means of confirmatory factor analysis. Significance was set at 0.05.ResultsThe PAM13-B presented appropriate results for internal consistency (α = 0.83) and test–retest reliability (intraclass correlation coefficient [ICC] = 0.81). A moderate correlation was found between activation and self-esteem only (r = 0.43, p < 0.001). The one-dimensional structure was not confirmed in the sample analyzed.ConclusionsIn the study sample, the version PAM13-B demonstrated its reliability and validity, but with a two-factor structure.
