ABSTRACT Objective: To test the construct validity, reliability, and measurement error of the Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living (MRADL) questionnaire in patients with COPD. Methods: We evaluated 50 patients with COPD, among whom 30 were men, the mean age was 64 ± 8 years, and the median FEV1 as a percentage of the predicted value (FEV1%predicted) was 38.4% (interquartile range, 29.1-57.4%). Pulmonary function and limitations in activities of daily living (ADLs) were assessed by spirometry and by face-to-face application of the MRADL, respectively. For the construct validity analysis, we tested the hypothesis that the total MRADL score would show moderate correlations with spirometric parameters. We analyzed inter-rater reliability, test-retest reliability, inter-rater measurement error, and test-retest measurement error. Results: The total MRADL score showed moderate correlations with the FEV1/FVC ratio, FEV1 in liters, FEV1%predicted, and FVC%predicted, all of the correlations being statistically significant (r = 0.34, r = 0.31, r = 0.42, and r = 0.38, respectively; p < 0.05 for all). For the reliability and measurement error of the total MRADL score, we obtained the following inter-rater and test-retest values, respectively: two-way mixed-effects model intraclass correlation coefficient for single measures, 0.92 (95% CI: 0.87-0.96) and 0.89 (95% CI: 0.81-0.93); agreement standard error of measurement, 1.03 and 0.97; smallest detectable change at the individual level, 2.86 and 2.69; smallest detectable change at the group level, 0.40 and 0.38; and limits of agreement, −2.24 to 1.96 and −2.65 to 2.69. Conclusions: In patients with COPD in Brazil, this version of the MRADL shows satisfactory construct validity, satisfactory inter-rater/test-retest reliability, and indeterminate inter-rater/test-retest measurement error.

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.

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).

BACKGROUND: To date the Neck OutcOme Score (NOOS) was not cross-culturally adapted, validated or available in the Arabic language, although it was available in other languages. OBJECTIVE: To translate and cross-culturally adapt the Arabic version of the Neck OutcOme Score (NOOS-Ar) and study its psychometric properties. METHODS: A sample of 146 subjects with chronic neck pain filled in the NOOS-Ar questionnaire to determine the Cronbach’s alpha (α) for internal consistency, test-retest reliability by intraclass correlation coefficients(2,1) [ICC(2,1)], inter-item correlation, measurement error by coefficient of variance and minimal detectable change, ceiling and floor effects, convergent construct validity with visual analog scale (VAS) by Spearman’s rank correlation coefficient (ρ) and factor analysis to calculate and determine its psychometric properties. RESULTS: Excellent internal consistency (Cronbach’s α> 0.9) and test-retest reliability [ICC(2,1)> 0.9] were observed in NOOS-Ar. None of the five subscales of the NOOS-Ar showed a floor or ceiling effect. The coefficient of variance was generally high, but the minimal detectable change was within the acceptable range (< 30%). The ‘everyday activity and pain’ and ‘symptoms’ subscales of the NOOS-Ar, showed a moderate correlation with VAS. CONCLUSION: The NOOS-Ar is highly reliable and has a moderate to good degree of convergent construct validity with VAS with no floor or ceiling effects.

Test Retest Reliability

The Safety Assessment of Function and the Environment for Rehabilitation (SAFER Too)) was developed to assess people's abilities to manage functional activities safety within their homes. The results of a study to evaluate the instruments inter-rater and test-retest reliability and construct validity are reported. Reliability was evaluated using kappa for each dichotomous item. For inter-rater reliability, 59 of 66 items had acceptable reliability. For test-retest reliability, 63 of 70 items had acceptable kappa scores. For items where kappa could not be calculated because of limited variation between raters, percentage agreement was over 80%. For validity, higher SAFER Tool scores (that is, more safety problems) were hypothesised to be associated with less independence in activities of daily living (ADL) and instrumental activities of daily living (IADL) and more cognitive impairment. The correlation between SAFER Tool scores and cognitive impairment supported this hypothesis. The results of the correlations with ADL and IADL scores were less clear. This could be attributed to caregivers' assistance with activities which might have reduced risk, and generally limited variation in ADL scores. The reliability results from this study are positive. Further research to assure the SAFER Tools validity and predictive ability are needed.

Absolute Reliability

Background and Purpose: The Berg Balance Scale (BBS) is frequently used to assess balance in older people, but knowledge is lacking about the absolute reliability of BBS scores. The aim of this study was to investigate the absolute and relative intrarater test-retest reliability of data obtained with the BBS when it is used among older people who are dependent in activities of daily living and living in residential care facilities.Subjects: The participants were 45 older people (36 women and 9 men) who were living in 3 residential care facilities. Their mean age was 82.3 years (SD=6.6, range=68–96), and their mean score on the Mini Mental State Examination was 17.5 (SD=6.3, range=4–30).Methods: The BBS was assessed twice by the same assessor. The intrarater test-retest reliability assessments were made at approximately the same time of day and with 1 to 3 days in between assessments. Absolute reliability was calculated using an analysis of variance with a 95% confidence level, as suggested by Bland and Altman. Relative reliability was calculated using the intraclass correlation coefficient (ICC).Results: The mean score was 30.1 points (SD=15.9, range=3–53) for the first BBS test and 30.6 points (SD=15.6, range=4–54) for the retest. The mean absolute difference between the 2 tests was 2.8 points (SD=2.7, range=0–11). The absolute reliability was calculated as being 7.7 points, and the ICC was calculated to .97.Discussion and Conclusion: Despite a high ICC value, the absolute reliability showed that a change of 8 BBS points is required to reveal a genuine change in function among older people who are dependent in activities of daily living and living in residential care facilities. This knowledge is important in the clinical setting when evaluating an individual's change in balance function over time in this group of older people.

To determine the test–retest reliability and criterion validity of self-reported function in mobility and instrumental activities of daily living (IADL) in older adults, a convenience sample of 70 subjects (72.9 ± 6.6 yr, 34 male) was split into able and disabled groups based on baseline assessment and into consistently able, consistently disabled, and inconsistent based on repeat assessments over 2 weeks. The criterion validities of the self-reported measures of mobility domain and IADL-physical subdomain were assessed with concurrent baseline measures of 4 mobility performances, and that of the self-reported measure of IADL-cognitive subdomain, with the Mini-Mental State Examination. Test–retest reliability was moderate for the mobility, IADL-physical, and IADL-cognitive subdomains (κ = .51–.66). Those who reported being able at baseline also performed better on physical- and cognitive-performance tests. Those with variable performance between test occasions tended to report inconsistently on repeat measures in mobility and IADL-cognitive, suggesting fluctuations in physical and cognitive performance.

PURPOSE: To contribute to the development of a Brazilian Portuguese language version of the vocal self-assessment questionnaire, Transsexual Voice Questionnaire: Male-to-Female (TVQ:MtF), and to evaluate the questionnaire for use in Brazil. METHODS: The research was divided into two parts: (1) translation and adaptation of the questionnaire (TVQ:MtF) and demographic form and (2) preliminary study of the psychometric properties (internal consistency and test-retest reliability) of the adapted version of the questionnaire. For the translation and adaptation, the following steps were taken: translation, reconciliation, back-translation, harmonization, and pilot test. The TVQ:MtF questionnaire and the demographic form were applied to 13 male-to-female transsexuals, aged between 21 and 47 years. The participants agreed to answer the TVQ:MtF on two occasions (test and retest), with an optimal interval of 30 days. RESULTS: Two psychometric properties were investigated: internal consistency and test-retest reliability. High levels of internal consistency (in both test (α=0.911) and retest (α=0.952) conditions) and reliability (with an average ICC=0.957 (95%CI 0.916-0.984)), were found. CONCLUSION: The TVQ:MtF is an appropriate instrument for vocal self-assessment of male-to-female transsexual patients, which can be recommended for clinical and research goals.

Test Retest Reliability

Introduction In Denmark, there is a growing need for valid, reliable and standardized patient-rated outcome measures for use in clinical practice and research. The Patient-Rated Wrist/Hand Evaluation (PRWHE) is a self-reported assessment of hand-related disorders that measures pain and functional difficulties in activities of daily living. The purpose of this study was to: (1) translate and cross-culturally adapt the PRWHE into Danish and (2) assess the reliability and construct validity of the Danish version in patients with hand-related disorders. Methods The PRWHE was translated and cross-culturally adapted into Danish using the dual-panel approach. A total of 97 patients with diverse hand-related disorders and a mean age of 52.6 years (SD 15.2) participated in the psychometric testing. They were assessed on two occasions. Test–retest reliability was assessed using the Intraclass Correlation Coefficient (ICC2.1) to assess test–retest, Cronbach’s alpha to assess internal consistency and a Bland–Altman plot to estimate measurement error. Construct validity was investigated by evaluating the relationship between the Danish PRWHE (PRWHE-DK) and the Danish validated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). Results Psychometric testing demonstrated an excellent test–retest reliability (ICC2.1 = 0.94) and internal consistency (alpha = 0.96). A systematic error of 1.5 and a measurement error of ± 16.1 were found. Furthermore, a strong correlation was found between PRWHE-DK and DASH ( r = 0.71). Conclusions The PRWHE-DK is a reliable, valid instrument for patients with different kinds of hand-related disorders, and can be used in clinical practice and multi-cultural research studies to measure pain and functional disability.
