Purpose: Auditory-perceptual evaluation is essential for the assessment of voice quality. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) provides a standardized protocol and assessment form for clinicians to analyze the voice quality and has been adapted into several different languages. The aims of this study were to develop the Japanese version of the CAPE-V and to investigate its reliability and validity. Method: The Japanese CAPE-V consisted of the same three speech contexts (vowels, sentences, and conversation) as developed in the original English version. The sentences were designed according to the concepts of the original version and reviewed by Japanese phoneticians. To validate the usefulness of the Japanese CAPE-V, voices of 173 Japanese-speaking subjects (76 subjects with dysphonia and 97 without voice complaints) were evaluated by five experienced judges, according to the Japanese CAPE-V as well as the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale. Results: The Japanese CAPE-V provided a high interrater reliability (intraclass correlation coefficients [ICCs] > .85 for all the parameters) as well as a high intrarater reliability (ICCs > .85 for all the parameters). In addition, overall severity, roughness, and breathiness in the Japanese CAPE-V were highly correlated with the corresponding dimensions in the GRBAS scale, having Spearman correlation coefficients greater than .8. Conclusion: This study demonstrated the reliability and validity of the newly developed Japanese CAPE-V as an auditory-perceptual evaluation instrument.

The Posture and Fine Motor Assessment of Infants (PFMAI) (Case-Smith, 1987) is a newly developed instrument for assessing the quality of motor function in infants. The test measures components of posture and fine motor control as they first develop. The purpose of this study was to support the test's reliability and validity. Interrater reliability, analyzed with intraclass correlation coefficients (ICCs), was high (.989 for total scores). Test-retest reliability, measured by ICCs, was .853 and .913 for the two test sections. The PFMAI demonstrated concurrent validity with the Peabody Developmental Motor Scales, Revised (Folio & Fewell, 1983) (correlations were .673 and .829 for the individual sections). Scores on the PFMAI were highly correlated with the infant's ages (.892 to .941); this finding provided one indication of construct validity.

AbstractWe evaluated the reliability and validity of the 5-scale grading system to interpret the point-of-care immunoassay for tear matrix metalloproteinase (MMP)-9. Six observers graded red bands of photographs of the readout window in MMP-9 immunoassay kit (InflammaDry) two times with 2-week interval based on the 5-scale grading system (i.e. grade 0–4). Interobserver and intraobserver reliability were evaluated using intraclass correlation coefficients. The interobserver agreements were analyzed according to the severity of tear MMP-9 expression. To validate the system, a concentration calibration curve was made using MMP-9 solutions with reference concentrations, then the distribution of MMP-9 concentrations was analyzed according to the 5-scale grading system. Both intraobserver and interobserver reliability was excellent. The readout grades were significantly correlated with the quantified colorimetric densities. The interobserver variance of readout grades had no correlation with the severity of the measured densities. The band density continued to increase up to a maximal concentration (i.e. 5000 ng/mL) according to the calibration curve. The difference of grades reflected the change of MMP-9 concentrations sensitively, especially between grade 2 and 4. Together, our data indicate that the subjective 5-scale grading system in the point-of-care MMP-9 immunoassay is an easy and reliable method with acceptable accuracy.

BACKGROUND An increasing number of wrist-worn wearables are being examined in the context of health care. However, studies of their use during physical education (PE) lessons remain scarce. OBJECTIVE We aim to examine the reliability and validity of the Fizzo Smart Bracelet (Fizzo) in measuring heart rate (HR) in the laboratory and during PE lessons. METHODS In Study 1, 11 healthy subjects (median age 22.0 years, IQR 3.75 years) twice completed a test that involved running on a treadmill at 6 km/h for 12 minutes and 12 km/h for 5 minutes. During the test, participants wore two Fizzo devices, one each on their left and right wrists, to measure their HR. At the same time, the Polar Team2 Pro (Polar), which is worn on the chest, was used as the standard. In Study 2, we went to 10 schools and measured the HR of 24 students (median age 14.0 years, IQR 2.0 years) during PE lessons. During the PE lessons, each student wore a Polar device on their chest and a Fizzo on their right wrist to measure HR data. At the end of the PE lessons, the students and their teachers completed a questionnaire where they assessed the feasibility of Fizzo. The measurements taken by the left wrist Fizzo and the right wrist Fizzo were compared to estimate reliability, while the Fizzo measurements were compared to the Polar measurements to estimate validity. To measure reliability, intraclass correlation coefficients (ICC), mean difference (MD), standard error of measurement (SEM), and mean absolute percentage errors (MAPE) were used. To measure validity, ICC, limits of agreement (LOA), and MAPE were calculated and Bland-Altman plots were constructed. Percentage values were used to estimate the feasibility of Fizzo. RESULTS The Fizzo showed excellent reliability and validity in the laboratory and moderate validity in a PE lesson setting. In Study 1, reliability was excellent (ICC>0.97; MD<0.7; SEM<0.56; MAPE<1.45%). The validity as determined by comparing the left wrist Fizzo and right wrist Fizzo was excellent (ICC>0.98; MAPE<1.85%). Bland-Altman plots showed a strong correlation between left wrist Fizzo measurements (bias=0.48, LOA=–3.94 to 4.89 beats per minute) and right wrist Fizzo measurements (bias=0.56, LOA=–4.60 to 5.72 beats per minute). In Study 2, the validity of the Fizzo was lower compared to that found in Study 1 but still moderate (ICC>0.70; MAPE<9.0%). The Fizzo showed broader LOA in the Bland-Altman plots during the PE lessons (bias=–2.60, LOA=–38.89 to 33.69 beats per minute). Most participants considered the Fizzo very comfortable and easy to put on. All teachers thought the Fizzo was helpful. CONCLUSIONS When participants ran on a treadmill in the laboratory, both left and right wrist Fizzo measurements were accurate. The validity of the Fizzo was lower in PE lessons but still reached a moderate level. The Fizzo is feasible for use during PE lessons.

Force Data

The assessment of loading during walking and running has historically been limited to data collection in laboratory settings or with devices that require a computer connection. This study aims to determine if the loadsol®—a single sensor wireless insole—is a valid and reliable method of assessing force. Thirty (17 male and 13 female) recreationally active individuals were recruited for a two visit study where they walked (1.3 m/s) and ran (3.0 and 3.5 m/s) at a 0%, 10% incline, and 10% decline, with the visits approximately one week apart. Ground reaction force data was collected on an instrumented treadmill (1440 Hz) and with the loadsol® (100 Hz). Ten individuals completed the day 1 protocol with a newer 200 Hz loadsol®. Intraclass correlation coefficients (ICC3,k) were used to assess validity and reliability and Bland–Altman plots were generated to better understand loadsol® validity. Across conditions, the peak force ICCs ranged from 0.78 to 0.97, which increased to 0.84–0.99 with the 200 Hz insoles. Similarly, the loading rate ICCs improved from 0.61 to 0.97 to 0.80–0.96 and impulse improved from 0.61 to 0.97 to 0.90–0.97. The 200 Hz insoles may be needed for loading rate and impulse in running. For both walking and running, the loadsol® has excellent between-day reliability (>0.76).

Abstract Background and Purpose. The goal of this study was to examine the reliability and validity of measurements obtained with the Alberta Infant Motor Scale (AIMS) for evaluation of preterm infants in Taiwan. Subjects. Two independent groups of preterm infants were used to investigate the reliability (n=45) and validity (n=41) for the AIMS. Methods. In the reliability study, the AIMS was administered to the infants by a physical therapist, and infant performance was videotaped. The performance was then rescored by the same therapist and by 2 other therapists to examine the intrarater and interrater reliability. In the validity study, the AIMS and the Bayley Motor Scale were administered to the infants at 6 and 12 months of age to examine criterion-related validity. Results. Intraclass correlation coefficients (ICCs) for intrarater and interrater reliability of measurements obtained with the AIMS were high (ICC=.97–.99). The AIMS scores correlated with the Bayley Motor Scale scores at 6 and 12 months (r=.78 and .90), although the AIMS scores at 6 months were only moderately predictive of the motor function at 12 months (r=.56). Conclusion and Discussion. The results suggest that measurements obtained with the AIMS have acceptable reliability and concurrent validity but limited predictive value for evaluating preterm Taiwanese infants.

School Function Assessment

The purpose of this study was to examine the reliability and validity of the School Function Assessment (SFA)-Chinese version. The data drawn from the standardization sample of the instrument (N = 320) were used in the analyses. Using internal consistency procedures, Cronbach's alpha for each scale ranged from .94 to .98. The test—retest study reported intraclass correlation coefficients from .87 to .98 among the scales. Content validity of the SFA—Chinese version was confirmed by the overall high content validity indices (85% to 100%) determined by educational experts. Construct-related validity based on an exploratory factor analysis revealed two correlated functional domains of the SFA—Chinese version, “cognitive/behavioral” and “physical,” which were consistent with the theoretical construct hypothesized in the instrument. The known groups method demonstrated different patterns of the SFA scores among three different diagnostic groups. Moreover, discriminant analysis of the scores showed a high percentage of children correctly classified into their diagnostic groups. The overall results supported the psychometric properties of the SFA—Chinese version.

Test Retest Reliability

Clinicians are in need of valid and objective measures of postural sway. Accelerometers have been shown to be suitable alternatives to expensive and stationary force plates. We evaluated the test-retest reliability and balance task discrimination capability of a new wireless triaxial accelerometer (YEI 3-Space Sensor). Four testing conditions (eyes open or closed, while on a firm or compliant surface) were used to progressively challenge the static balance of 20 healthy male (n = 8) and female (n = 12) older adults (mean age 81 ± 4.3 y). Subjects completed 2 blocks of three 30-second trials per condition. The accelerometer was positioned on the lower back to acquire mediolateral (M-L) and anterior-posterior (A-P) accelerations. Intraclass correlation coefficients were all good to excellent, with values ranging from .736 to .972 for trial-to-trial and from .760 to .954 for block-to-block. A significant stepwise increase in center of mass acceleration root mean square values was found across the 4 balance conditions (F[1.49, 28.26] = 39.54, P < .001). The new accelerometer exhibited good to excellent trial-to-trial and block-to-block reliability and was sensitive to differences in visual and surface conditions and acceleration axes.

Background: Clinical measures in multiple sclerosis (MS) face limitations that may be overcome by utilising smartphone keyboard interactions acquired continuously and remotely during regular typing. Objective: The aim of this study was to determine the reliability and validity of keystroke dynamics to assess clinical aspects of MS. Methods: In total, 102 MS patients and 24 controls were included in this observational study. Keyboard interactions were obtained with the Neurokeys keyboard app. Eight timing-related keystroke features were assessed for reliability with intraclass correlation coefficients (ICCs); construct validity by analysing group differences (in fatigue, gadolinium-enhancing lesions on magnetic resonance imaging (MRI), and patients vs controls); and concurrent validity by correlating with disability measures. Results: Reliability was moderate in two (ICC = 0.601 and 0.742) and good to excellent in the remaining six features (ICC = 0.760–0.965). Patients had significantly higher keystroke latencies than controls. Latency between key presses correlated the highest with Expanded Disability Status Scale ( r = 0.407) and latency between key releases with Nine-Hole Peg Test and Symbol Digit Modalities Test (ρ = 0.503 and r = −0.553, respectively), ps < 0.001. Conclusion: Keystroke dynamics were reliable, distinguished patients and controls, and were associated with clinical disability measures. Consequently, keystroke dynamics are a promising valid surrogate marker for clinical disability in MS.

Physical activity (PA) is a component of total energy expenditure. PA and PA energy expenditure (PAEE) can be estimated by objective techniques (OTs). However, the use of questionnaires is frequent in clinical settings and epidemiological studies. We conducted a search on PubMed, Scopus, and Google Scholar databases to perform a review of studies reporting the reliability and validity of PA questionnaires validated against OTs—doubly labeled water (DLW) or accelerometers—in free-living adults. We selected original articles published between 2009 and 2019 that reported validation studies of PA questionnaires. We identified 53 studies that fulfilled the eligibility criteria. Four PA questionnaires were validated against DLW and the remaining against accelerometers. Three questionnaires were compared with both DLW and accelerometer results. The correlation between questionnaire-estimated PAEE and DLW results ranged from r = .22 to r = .46, while that between questionnaire-estimated total PA (TPA) and accelerometer results ranged from r = .11 to r = .54 The intraclass correlation coefficients were between .56 and .84. Despite having good reliability, most of the questionnaires included in this review have shown limited validity for estimating TPA in adults. OTs should be considered as a first option, when possible. Further research is warranted on techniques to obtain more accurate PA and PAEE estimates.

Purpose: To investigate stereo acuity of professional athletes in an open (baseball) and closed (golf) skilled sport compared to nonathletes using a new digitized version of the Titmus Stereo Test/Wirt Circles. Additionally, to examine the new test for reliability and validity. Methods: Participants included professional baseball players (PBP; n = 265) and professional women golfers (LPGA; n = 52), and nonathletes (n = 107). All participants were tested on the RightEye Fine Depth Perception (FDP) test and a subset (n = 20) was retested to determine reliability and internal consistency. A different subset (n = 81) was tested for validity comparing the Titmus Stereo Test/Wirt Circles to the RightEye FDP test. Cronbach’s Alpha, intraclass correlation coefficients (ICC) were examined for reliability and ANOVA was conducted to determine convergent validity as well as differences in stereo acuity between groups. Results: Results: The test was revealed to have high reliability and validity, therefore being a good measure of stereo acuity. Furthermore, significant differences (p<.001) between athletes and non-athletes were found. Both PBP and LPGA athletes were significantly different from non-athletes (p<.05). No differences were found between athlete groups. Conclusions: The RightEye FDP test is both reliable and valid and can therefore be used confidently as a measure of static stereo acuity. Elite athletes in open and closed skills show significantly better stereo acuity than non-athletes.
