OBJECTIVE: To validate a Portuguese-language version of the COPD assessment test (CAT) for use in Brazil and to assess the reproducibility of this version. METHODS: This was multicenter study involving patients with stable COPD at two teaching hospitals in the city of Fortaleza, Brazil. Two independent observers (twice in one day) administered the Portuguese-language version of the CAT to 50 patients with COPD. One of those observers again administered the scale to the same patients one week later. At baseline, the patients were submitted to pulmonary function testing and the six-minute walk test (6MWT), as well as completing the previously validated Portuguese-language versions of the Saint George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (MMRC) dyspnea scale, and hospital anxiety and depression scale (HADS). RESULTS: Inter-rater and intra-rater reliability was excellent (intraclass correlation coefficient [ICC] = 0.96; 95% CI: 0.93-0.97; p < 0.001; and ICC = 0.98; 95% CI: 0.96-0.98; p < 0.001, respectively). Bland Altman plots showed good test-retest reliability. The CAT total score correlated significantly with spirometry results, 6MWT distance, SGRQ scores, MMRC dyspnea scale scores, and HADS-depression scores. CONCLUSIONS: The Portuguese-language version of the CAT is a valid, reproducible, and reliable instrument for evaluating patients with COPD in Brazil.

ABSTRACT Objective: To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. Methods: This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD) and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), and Fatigue Severity Scale (FSS). Inflammatory status was assessed by blood C-reactive protein (CRP) levels. To validate the ICFS, we assessed the correlations of its scores with those variables. Results: The sample comprised 50 patients in each group (LC, CHD, and control). In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. Conclusions: The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

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.

BackgroundThere is no reliable and valid self-report measure of depressive symptoms for people with learning disabilities.AimsTo develop a scale for individuals with learning disability, and a supplementary scale for carers.MethodItems were generated from a range of assessment scales and through focus groups. A draft scale was piloted and field tested using matched groups of people with or without depression, and their carers. The scale was also administered to a group without learning disabilities for criterion validation.ResultsThe Glasgow Depression Scale for people with a Learning Disability (GDS–LD) differentiated depression and non-depression groups, correlated with the Beck Depression Inventory – II (r=0.88), had good test – retest reliability (r=0.97) and internal consistency (Cronbach's α=0.90), and a cut-off score (13) yielded 96% sensitivity and 90% specificity. The Carer Supplement was also reliable (r=0.98; α=0.88), correlating with the GDS–LD (r=0.93).ConclusionsBoth scales appear useful for screening, monitoring progress and contributing to outcome appraisal.

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.

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.

Background: There is no valid and reliable patient self-reported measure assessing symptomology among outpatients with COVID-19. The Symptoms Evolution of COVID-19 (SE-C19) is a self-administered new instrument that includes 23 symptoms, each rated for severity at their worst moment within the last 24 hours. We studied the psychometric properties of SE-C19. Methods: Reliability, validity, and sensitivity to change of the SE-C19 were assessed in 657 outpatients with confirmed COVID-19 enrolled in NCT04425629. SE-C19 and Patient Global Impression of Severity (PGIS) were administered daily from baseline (predose at Day 1) to end of study (Day 29). Findings: Most patients (70.0%) were aged ≤50 years and white (85.5%). At baseline, patients reported an average (SD) of 6.6 (3.9) symptoms (ie, rated as at least Mild) with 3.8 (3.3) of these symptoms being rated as Moderate or Severe. By Day 29, most symptoms had resolved; 74.4% of patients reported no symptoms and on average, only 0.6 (SD 1.5) were reported as at least Mild. Stable patients according to the PGIS showed scores with intraclass correlation values indicating moderate-to-good test-retest reliability (ie, 0.50-0.90). At baseline, 20 item scores (87%) varied significantly across PGIS defined groups supporting the validity of SE-C19. A symptom resolution endpoint was defined after excluding the item 'Sneezing', due to its low ability to discriminate severity levels, and 'Confusion', 'Rash', and 'Vomiting', due to their low prevalence in this population. Symptoms resolution required complete absence of all remaining items, except 'Cough', 'Fatigue', and 'Headache', which could be Mild or Moderate in severity. Interpretation: We identified 19 items that are valid and reliable to measure disease-related symptoms in COVID-19 outpatients and propose a definition of symptom resolution that could be used in future clinical trials and potentially, also in clinical practice.

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.
