Reliability and Validity of a Questionnaire for Assessing Self-Perceived Health-Related Fitness in Spanish Children

Abstract There is a need for developing tools aimed at assessing fitness in children, due to its relationship with health. This study is aimed at testing the reliability and the validity of a questionnaire designed for assessing self-perceived health-related fitness in Spanish children. The questionnaire was created based on the model of physical self-concept developed by Fox and Corbin (1989) who conceived four sub-domains: Sport competence, attractive body, strength and physical condition. A total of 283 children (mean age: 10.80 ± 0.69 years; 45.6% girls) answered the questionnaire twice, in order to determine its test-retest reliability. The results obtained in the International Fitness Scale (IFIS) and on a fitness battery were used to determine its validity evidence based on relations to other variables. Exploratory and factorial analyses were performed to check its validity evidence based on internal structure. The obtained results indicated that the questionnaire showed an accurate validity evidence based on internal structure and a very good test-retest reliability, Intraclass correlation coefficient: .88; 95% CI [.84, .90]. The questionnaire established moderate correlations with the IFIS questionnaire (ρ = –.51 to –.68) and the fitness level showed by the children (ρ = –.53). These findings indicate that the questionnaire can be a useful research tool for assessing self-perceived health-related fitness in children.

Test Retest Reliability

ObjectiveTo evaluate health-related quality of life (HRQoL) in Cushing's syndrome (CS) with the disease-generated CushingQoL questionnaire and to confirm its psychometric properties of test–retest reliability and sensitivity to change.DesignClinical practice conditions in a tertiary referral center.MethodsThe CushingQoL and EuroQoL questionnaires were administered at baseline and during follow-up and correlated with clinical parameters in 59 patients with CS. To check test–retest reliability, stable patients (either biochemically cured or with active hypercortisolism) were evaluated twice. To investigate sensitivity to change, new patients were evaluated at diagnosis and twice more following improvement after successful surgery.ResultsAt baseline, patients with active disease scored lower (indicating worse HRQoL) than those cured on the CushingQoL (46±14 vs 58±20, P<0.05) but not on the EuroQoL-visual analog scale (VAS; 64±20 vs 70±16, P NS). Test–retest reliability of CushingQoL was confirmed in stable patients, both in the ‘cured group’ (intraclass correlation coefficient (ICC)=0.78, n=34) and in the ‘active group’ (ICC=0.66, n=14). Sensitivity to change was confirmed in the ‘improvement group’ (n=11), as the CushingQoL score increased 4±1.5 and 9±3 months after surgery (P<0.01 and <0.001 respectively); the EuroQoL-VAS only improved after 9±3 months (P<0.01). Effect sizes were 1.02 and 1.86 for CushingQoL at 4±1.5 and 9±3 months respectively. Finally, scores of both questionnaires were correlated (r=0.504; P<0.001).ConclusionsThe CushingQoL questionnaire shows good test–retest reliability and sensitivity to change in clinical practice conditions.

Purpose: To examine the test–retest reliability of student-administered (SA) health-related fitness tests in school settings and to compare indices of reliability with those taken by trained research-assistants. Methods: Participants (n = 86; age: 13.43 [0.33] y) were divided into 2 groups, SA (n = 45, girls = 26) or research-assistant administered (RA; n = 41, girls = 21). The SA group had their measures taken by 8 students (age: 15.59 [0.56] y, girls = 4), and the RA group had their measures taken by 8 research-assistants (age: 21.21 [1.38], girls = 5). Tests were administered twice by both groups, 1 week apart. Tests included body mass index, handgrip strength, standing broad jump, isometric plank hold, 90° push-up, 4 × 10-m shuttle run, back-saver sit and reach, and blood pressure. Results: Intraclass correlation coefficients for SA (≥.797) and RA (≥.866) groups were high, and the observed systematic error (Bland–Altman plot) between test 1 and test 2 was close to 0 for all tests. The coefficient of variation was less than 10% for all tests in the SA group, aside from the 90° push-up (24.3%). The SA group had a marginally lower combined mean coefficient of variation across all tests (6.5%) in comparison with the RA group (6.8%). Conclusion: This study demonstrates that, following familiarization training, SA health-related fitness tests in school-based physical education programs can be considered reliable.

Background: The Podiatric Health Questionnaire (PHQ) is a health-related questionnaire consisting of six questions designed for measuring foot health status. To date, the PHQ has only been validated in the English-language version. Thus, this study aimed to perform the Spanish translation and test–retest procedures of the PHQ (PHQ-S). Method: The forward/backward translation and test–retest reliability methods were applied from English to Spanish languages. Regarding the total score for each domain, internal consistency and reliability were determined by the Cronbach α and intraclass correlation coefficient (ICC) with a confidence interval (CI) of 95%. Results: High internal consistency was shown for the six domains: (1) walking with a Cronbach α of 0.97; (2) hygiene and nail care with 0.93 and 093, respectively; (3) foot pain with 0.91; (4) worry and concern domain with 0.904; (5) quality of life with 0.87; and (6) the self-perception of how their feet are feeling measured by a visual analogic scale with 0.92. Excellent test–retest reliability (ICC = 0.99 (95% CI = 0.96–0.98)) was shown for the total score. Conclusions: The PHQ-S was shown to be a valid and reliable tool for an acceptable use in the Spanish population.

Linguistic, reliable, and valid secondary efficacy measures are important in clinical settings and studies. The aim of the study is to report test–retest reliability and construct validity of Turkish version of Myasthenia Gravis-Activities of Daily Living Scale (MG-ADL-T) in Myasthenia Gravis (MG) patients. Fifty-two ocular and generalized individuals with MG, applying to rehabilitation center, were included in the study. MG-ADL-T, MG quality-of-life questionnaire (MG-QoL), MG composite (MGC), quantitative MG score (QMGS), and pulmonary function test were administered. Reliability was assessed with intraclass correlation coefficient (ICC) and Cronbach’s alpha. Spearman correlation test and receiver operating characteristic (ROC) analysis were performed for construct validity. MG-ADL-T had fair internal consistency (Cronbach’s α = .67), excellent test–retest reliability (ICC = 0.96) and moderate construct validity (MG-QoL, r = 0.59; QMGS, r = .58; MGC, r = .68). MG-ADL, a unique scale that evaluates activities of daily living (ADL), has good test–retest reliability and construct validity in Turkish MG patients.

Standard Error Of Measurement

Background: Usage of wrist-worn activity monitors has rapidly increased in recent years, and these devices are being used by both fitness enthusiasts and in clinical populations. We, therefore, assessed the test–retest reliability of the Polar Vantage M (PVM) watch when measuring heart rate (HR) during various treadmill exercise intensities. Methods: HR was measured every 30 s (simultaneous electrocardiography (ECG) and PVM). Test–retest reliability was determined using an intraclass correlation coefficient (ICC) with 95% confidence intervals (CIs). Standard error of measurement (SEM) and smallest real difference (SRD) were used to determine measurement variability. Results: A total of 29 participants completed the trials. ICC values for PVM during stages 1, 2 and 5 demonstrated good to excellent test–retest reliability (0.78, 0.78 and 0.92; 95% CI (0.54–0.90, 0.54–0.9, 0.79–0.97)). For PVM during stages 0 (rest), 3 and 4, the ICC values indicated poor to good reliability (0.42, 0.68 and 0.58; 95% CI (−0.27–0.73, 0.32–0.85, 0.14–0.80)). Conclusion: This study identified that the test–retest reliability of the PVM was comparable at low and high exercise intensities; however, it revealed a poor to good test–retest reliability at moderate intensities. The PVM should not be used in a clinical setting where monitoring of an accurate HR is crucial to the patients’ safety.

Background:Activity Monitors give an objective measure of usual walking performance. This study aimed to examine the test-retest reliability of the StepWatch Activity Monitor outputs (mean steps/day; peak activity index; sustained activity indices of 1, 5, 20, 30, 60 minutes; steps at high, medium, and low stepping rates).Methods:Thirty healthy adults age 18 to 49 years wore the StepWatch for 2 3-day periods at least 1 week apart.Results:The intraclass correlation coefficients of the StepWatch outputs ranged from 0.44 to 0.91 over 3 days. The coefficient of variation ranged from 3.0% to 51.3% over the monitoring periods, with higher variation shown for shorter monitoring periods. The most reliable 5 outputs had 95% limits of agreement between 3-day periods that were less than 40%. These were mean steps/day (±39.1%), highest step rate in 1 (±17.3%) and 5 (±37.4%) minutes, peak activity index (±25.6%), and percentage of inactive time (±9.52%).Conclusions:Mean steps/day, highest step rate in 1 and 5 minutes, peak activity index, and percentage of inactive time have good test-retest reliability over a 3-day monitoring period, with lower reliability shown by the other StepWatch outputs. Monitoring over 1 or 2 days is less reliable.

BACKGROUND: The endogenous modulation of pain can be assessed through conditioned pain modulation (CPM), which can be quantified using subjective pain ratings or nociceptive flexion reflexes. However, to date, the test-retest reliability has only been investigated for subjective pain ratings.OBJECTIVE: To compare the test-retest reliability of CPM-induced changes, measured using subjective pain ratings and nociceptive flexion reflexes, to provide a reliable scoring parameter for future studies.METHOD: A total of 40 healthy volunteers each received painful electrical stimuli to the sural nerve to elicit nociceptive flexion reflexes. Reflex sizes and subjective pain ratings were recorded before and during the immersion of the contralateral hand in hot water to induce CPM as well as innocuous water as control. Measurements were repeated in a retest 28 days later.RESULTS: Intraclass correlation coefficients showed good test-retest reliabilities of CPM during the hot water stimulus for both scoring parameters. Subjective pain ratings also correlated between test and retest during the control stimulus.CONCLUSIONS: Subjective pain ratings and nociceptive flexion reflexes show comparable test-retest reliabilities, but they reflect different components of CPM. While subjective pain ratings appear to incorporate cognitive influences to a larger degree, reflex responses appear to reflect spinal nociception more purely.

First Session

Context: The Functional Movement Screen (FMS) is a popular test to evaluate the degree of painful, dysfunctional, and asymmetric movement patterns. Despite great interest in the FMS, test-retest reliability data have not been published. Objective: To assess the test-retest and interrater reliability of the FMS and to compare the scoring by 1 rater during a live session and the same session on video. Design: Cross-sectional study. Setting: Human performance laboratory in the sports medicine center. Patients or Other Participants: A total of 21 female (age = 19.6 ± 1.5 years, height = 1.7 ± 0.1 m, mass = 64.4 ± 5.1 kg) and 18 male (age = 19.7 ± 1.0 years, height = 1.9 ± 0.1 m, mass = 80.1 ± 9.9 kg) National Collegiate Athletic Association Division IA varsity athletes volunteered. Intervention(s): Each athlete was tested and retested 1 week later by the same rater who also scored the athlete's first session from a video recording. Five other raters scored the video from the first session. Main Outcome Measure(s): The Krippendorff α (K α) was used to assess the interrater reliability, whereas intraclass correlation coefficients (ICCs) were used to assess the test-retest reliability and reliability of live-versus-video scoring. Results: Good reliability was found for the test-retest (ICC = 0.6), and excellent reliability was found for the live-versus-video sessions (ICC = 0.92). Poor reliability was found for the interrater reliability (K α = .38). Conclusions: The good test-retest and high live-versus-video session reliability show that the FMS is a usable tool within 1 rater. However, the low interrater K α values suggest that the FMS within the limits of generalization should not be used indiscriminately to detect deficiencies that place the athlete at greater risk for injury. The FMS interrater reliability may be improved with better training for the rater.

Test Retest Reliability

Abstract Background The Performance-based measure of Executive Functions (PEF) with four domains is designed to assess executive functions in people with schizophrenia. The purpose of this study was to examine the test-retest reliability of the PEF administered by the same rater (intra-rater agreement) and by different raters (inter-rater agreement) in people with schizophrenia and to estimate the values of minimal detectable change (MDC) and MDC%. Methods Two convenience samples (each sample, n = 60) with schizophrenia were conducted two assessments (two weeks apart). The intraclass correlation coefficient (ICC) was analyzed to examine intra-rater and inter-rater agreements of the test-retest reliability of the PEF. The MDC was calculated through standard error of measurement. Results For the intra-rater agreement study, the ICC values of the four domains were 0.88–0.92. The MDC (MDC%) of the four domains (volition, planning, purposive action, and perfromance effective) were 13.0 (13.0%), 12.2 (16.4%), 16.2 (16.2%), and 16.3 (18.8%), respectively. For the inter-rater agreement study, the ICC values of the four domains were 0.82–0.89. The MDC (MDC%) were 15.8 (15.8%), 17.4 (20.0%), 20.9 (20.9%), and 18.6 (18.6%) for the volition, planning, purposive action, and performance effective domains, respectively. Conclusions The PEF has good test-retest reliability, including intra-rater and inter-rater agreements, for people with schizophrenia. Clinicians and researchers can use the MDC values to verify whether an individual with schizophrenia shows any real change (improvement or deterioration) between repeated PEF assessments by the same or different raters.

The Impact

Purpose The Voice Handicap Index (VHI) questionnaire assesses the impact of total laryngectomy on voice-related quality of life. This study evaluates the Mandarin VHI, including its internal consistency, test–retest reliability, content validity, and differences in scores for Mandarin alaryngeal patients with pneumatic artificial laryngeal (PA) and esophageal (ES) speech. Method Translation and validation of the VHI questionnaire was performed through the forward–backward translation technique. This study used a sample of 78 PA and 23 ES participants from Taiwan who completed the Mandarin VHI. Forty-two of the alaryngeal participants completed the Mandarin VHI twice over a period of 7–63 days. Results The measurement of the internal consistency of the Mandarin VHI showed a high Cronbach's alpha coefficient for the total score (.975) and the functional (.930), physical (.939), and emotional (.938) subscales. Based on the results of the intraclass correlation coefficients, good test–retest reliability for the total and domain scores was found (intraclass correlation coefficient = .827–.863). Conclusion The Mandarin VHI was validated as an instrument with proper internal consistency and reliability, which supports the Mandarin VHI as a valid instrument for the self-evaluation of handicaps related to voice problems in PA and ES speakers.
