Test/Retest Reliability and Inter-Rater Agreement of the Quality of Upper Extremities Skills Test (QUEST) for Older Children with Acquired Brain Injuries

Patients with bronchiectasis feature considerable symptom burden and reduced health-related quality of life (QOL). We provide the psychometric validation of the German translation of the disease-specific Quality of Life Questionnaire-Bronchiectasis (QOL-B), version 3.1, using baseline data of adults consecutively enrolled into the prospective German bronchiectasis registry PROGNOSIS. Overall, 904 patients with evaluable QOL-B scores were included. We observed no relevant floor or ceiling effects. Internal consistency was good to excellent (Cronbach’s α ≥0.73 for each scale). QOL-B scales discriminated between patients based on prior pulmonary exacerbations and hospitalizations, breathlessness, bronchiectasis severity index, lung function, sputum volume, Pseudomonas aeruginosa status and the need for regular pharmacotherapy, except for Social Functioning, Vitality and Emotional Functioning scales. We observed moderate to strong convergence between several measures of disease severity and QOL-B scales, except for Social and Emotional Functioning. Two-week test-retest reliability was good, with intraclass correlation coefficients ≥0.84 for each scale. Minimal clinical important difference ranged between 8.5 for the Respiratory Symptoms and 14.1 points for the Social Functioning scale. Overall, the German translation of the QOL-B, version 3.1, has good validity and test-retest reliability among a nationally representative adult bronchiectasis cohort. However, responsiveness of QOL-B scales require further investigation during registry follow-up.

Test Retest Reliability

PURPOSE The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is a well-validated instrument that assesses health-related quality of life (HRQOL) in cancer patients. It is used in cancer clinical trials in Europe, Canada, and the United States, and has demonstrated high reliability and validity in different groups of cancer patients. Despite thorough testing of reliability and validity, we have not identified any reports on its test/retest reliability; thus, a test/retest study was performed at the Norwegian Radium Hospital (NRH). MATERIALS AND METHODS Cancer patients from the outpatient clinic who were off treatment for > or = 3 months were eligible for the study. The EORTC QLQ-C30 was given to the patients when they presented for their visit. The second questionnaire was received by the patients 4 days later. Of 291 eligible patients, 270 (93%) agreed to participate and 190 (73%) completed both questionnaires. RESULTS The test/retest reliability measured by Pearson's correlation coefficient was high for all functional scales, with a range from .82 for cognitive and role function to .91 for physical function. The r value for global HRQOL was .85. For the symptom scales--nausea/vomiting, fatigue, and pain--the coefficients were .63, .83, and .86, respectively. The single-item coefficients ranged from .72 for diarrhea to .84 for financial impact. The Spearman rank correlation was in the same range for all dimensions. CONCLUSION The EORTC QLQ-C30 seems to yield high test/retest reliability in patients with various cancer diagnoses whose condition is not expected to change during the time of measurement.

Test Retest Reliability

Introduction. Multiple Sclerosis (MS) can affect cognitive function that might interfere with quality of life. Processing speed and memory are the most common area of cognitive impairment. Cognitive evaluation in daily practice is often difficult to be performed since it needs neuropsychological expert and is time-consuming. Brief International Cognitive Assessment for MS (BICAMS) is valid and practical for cognitive evaluation. This study aims to validate BICAMS in Indonesian MS patients and healthy controls (HC) and to analyse the effect of cognitive impairment on quality of life. Methods. BICAMS, which composes Symbol Digits Modalities Test (SDMT), California Verbal Learning Test-Second Edition (CVLT-II), and Brief Visuospatial Memory Test-Revised (BVMT-R), was translated and cross-culturally adapted to Indonesian from the original BICAMS and then administered to 40 Indonesian MS patients and 66 HC matched by sex, age, and education. Test-retest reliability was performed on 16-MS patients and 42 HC. Quality of life was measured using Multiple Sclerosis Quality of Life (MSQOL-54) instrument. Results. The SDMT, CVLT-II, and BVMT-R score in MS patients were significantly lower than those in HC (effect size, r: 0.61, 0.36, and 0.47, respectively). Test-retest reliability for all tests was satisfactory with correlation coefficient for SDMT, CVLT-II, and BVMT-R in MS subjects 0.86, 0.81, and 0.83, respectively. Using 5th percentile of HC score as cut-off, 15% MS subjects had impairment in one test, 27.5% in two tests, and 40% in three tests. BICAMS was moderately correlated with EDSS but was not correlated with disease duration and relapse rate. SDMT score correlated with physical function and physical and mental role limitation. Conclusion. BICAMS is valid and reliable for assessing cognitive function of Indonesia MS patients.

The emotional availability scales (EAS), 4th edition, are widely used in research and clinical practice to assess the quality of parent–child interaction. This study examined the short-term reliability and continuity of the EAS (4th ed.) assessed in two similar observational contexts over a one-week interval. Sixty-two Dutch parents (85% mothers) and their 9- to 12-month-old infants ( Mage = 10.07 months, SD = 0.47, 53% boys) were videotaped twice while they interacted with each other during several tasks (free play, structured play, book reading, toys taken away). The videotapes were coded with the EAS 4th edition by two reliable coders. Moderate to strong test–retest reliability was found for the three EA parent-dimensions: sensitivity, structuring, and nonintrusiveness. Child involvement was not reliable over a one-week period, and child responsiveness could only be reliably assessed in boys. Test–retest reliability of structuring was also higher for boys than for girls. Regarding continuity, mean levels of sensitivity, structuring, nonintrusiveness, and involvement did not change over a one-week interval, but responsiveness increased for girls only. Thus, the parenting dimensions of the 4th edition of the EAS reflect stable and consistent characteristics of the parent–child dyad on the short term, but the child measures do not.

Test Retest Reliability

Background:The Orthotics and Prosthetics Users’ Survey consists of five modules to assess outcomes of orthotic and prosthetic interventions: lower extremity functional status, upper extremity functional status, client satisfaction with device, client satisfaction with services and health-related quality of life.Objectives:To investigate the test–retest reliability and calculate the smallest detectable difference for all modules of the Swedish Orthotics and Prosthetics Users’ Survey.Study design:Test–retest reliability study design.Methods:A total of 69 patients at a Department of Prosthetics and Orthotics completed Orthotics and Prosthetics Users’ Survey on two occasions separated by a 2-week interval, giving 18 answers on lower extremity functional status, 41 on upper extremity functional status, 53 on client satisfaction with device, 12 on client satisfaction with services and 67 answers on health-related quality of life. Raw scores were converted into Orthotics and Prosthetics Users’ Survey units on a 0–100 scale. Intra-class correlation coefficients, Bland–Altman plots, common person linking plots and t-tests of person mean measures were used to investigate the reliability. The 95% confidence level smallest detectable differences were calculated.Results:The intra-class correlation coefficients ranged from 0.77 to 0.96 for the modules, and no systematic differences were detected between the response occasions. The smallest detectable differences ranged from 7.4 to 16.6 units.Conclusions:The test–retest reliability was satisfactory for all Orthotics and Prosthetics Users’ Survey modules. The smallest detectable difference was large on all modules except the health-related quality of life module.Clinical relevanceThe Orthotics and Prosthetics Users’ Survey modules are reliable and, thus, can be recommended for repeated measurements of patients over time. Relatively large changes are needed to achieve statistical significance when assessing individual patients.
