Abstract Objectives To determine the level of agreement between both proxy versions and the self-completed EQ-5D-5L. Design A randomized agreement study. Setting and participants We recruited 120 patients (compos mentis) and their proxies at the orthopaedic outpatient clinic. Patients completed the regular EQ-5D-5L and their proxy completed the proxy version of the EQ-5D-5L and rated the patients’ health from their own (proxy-proxy) perspective (i.e. how do you rate the health of the patient), and from the patient’s (proxy-patient) perspective (i.e. how do you think the patient would rate their own health if they were able to). Measures The primary outcome was the agreement between patients and their proxy, quantified as the intra class correlation coefficient for the EQ-5D-5L Utility score. Results Average Utility scores were 0.65 with the self completed EQ-5D-5L, versus 0.60 with the proxy-patient version and 0.58 with the proxy-proxy version. The ICC was 0.66 (95% CI 0.523, 0.753) for the proxy-patient perspective and 0.58 (95% CI 0.411, 0.697) for the proxy-proxy perspective. The mean gold standard score of the VAS-Health was 69.7 whereas the proxy-proxy perspective was 66.5 and the proxy-patient perspective was 66.3. Conclusion and implications The proxy-patient perspective yielded substantial agreement with the self completed EQ-5D-5L, while the agreement with the proxy-proxy perspective was moderate. In this study population of patients without cognitive impairment, proxies tended to underestimate the quality of life of their relative.

Objectives To determine the validity and reliability of a Latvian version of the National Institutes of Health Stroke Scale (LV-NIHSS) for evaluating Latvian stroke patients. Methods The adaption of the LV-NIHSS followed standard methods used for the adaption and validation of clinical assessment tools. The scale validity was tested by comparison with the Glasgow Coma Scale (GCS) and the modified Rankin scale (mRs). The reliability of the LV-NIHSS was evaluated by intra-rater and inter-rater agreement using intra-class correlation coefficient (ICC) analysis. Results A total of 296 stroke patients and 101 control subjects were evaluated. The mean age of the overall study population was 73.6 years (range, 37 – 94 years; 227 [57.2%] were female). The mean LV-NIHSS score of the patients with stroke was 8.4 ± 6.2. In terms of construct validity of the LV-NIHSS, it correlated with the GCS ( r = −0.571) and mRs ( r = 0.755). In terms of the reliability of the LV-NIHSS, the inter-rater agreement had an ICC of 0.99 and the intra-rater agreement had an ICC of 0.99. Conclusion The adaption of LV-NIHSS was successful and the evaluation showed that the scale was valid and reliable for evaluating Latvian stroke patients.

Introduction: There is an increasing interest regarding the impact of skin diseases on quality of life. Skindex-29 is a questionnaire developed to evaluate this impact. This study aimed to validate Skindex-29 for the Portuguese population.Material and Methods: From the 81 approached patients from two clinics, only 75 finished the study: 35 with skin disease and 40 without. A translation and back-translation were performed. Concerning accuracy and discrimination power, the scores were submitted to ROC curve analysis after being compared between both groups through Mann-Whitney test. Internal consistency was measured using Cronbach’s α coefficient. Test/retest of each scale was assessed by the intra-class correlation coefficient, and by Kappa coefficient of agreement. Convergent validity was evaluated through Spearman correlations between Skindex-29 scores and SF-12 subscales. SPSS statistics and values of p < 0.05 with 95% confidence intervals were considered statistically significant.Results: The Skindex-29 demonstrated to be an accurate instrument and statistically significant differences were found when comparing the disease and without-disease groups (p < 0.001). The reliability was high (Cronbach’s α > 0.80) for each dimension ('Symptoms', 'Emotions' and 'Functioning') and for test-retest (ICC > 0.90, K > 0.494). About convergent validity, Skindex-29 Total score and the questions about 'Symptoms' and 'Functioning' were statistically correlated with the questions regarding the physical state of the SF-12 (-0.478; -0.459; -0.405, respectively).Discussion: Results suggest that Skindex-29 can be used as an instrument to evaluate skin diseases’ effect on quality of life in Portugal, being accurate and reliable. Despite having similar general health profiles as other individuals, dermatological patients showed a lower quality of life due to their disease. Results showed that Skindex-29 was better at assessing physical components rather than mental oremotional components.Conclusion: Skindex-29 appears to have evidence of validity including accuracy and reliability to be used as an instrument to evaluate the impact of skin diseases on quality of life in Portugal.

BACKGROUND: Validated tests for the quality of movement patterns are important to help teachers to assess and induce positive performance changes. However, few tests are available for handball sport skills. AIM: Therefore, we developed and validated a checklist to assess dribbling with a jumping throw. METHOD: First, three handball experts were invited to verify if the checklist which contained all the components that describe the skills, and the logical validity process. Then, fifty participants, aged 8 -12 years old, performed the skill of dribbling with a horizontal jumping throw, fifteen of them were re-tested one week apart. Two raters were also selected to conduct an intra- and inter-rater objectivity assessment. McNemar tests were used to compare the proportion of proficient and non-proficient performance between raters. Cohen’s k tests were used to test the intra and inter-rater objectivity. The intra-class correlation coefficient was used to estimated reliability (test-retest). RESULTS: The results confirmed that the checklist contained the necessary criteria to characterize the skill and to discriminate children with different proficiency levels. Moderate-to-high inter-and intra-rater agreements were found. Children's performance pre and post-test were highly reliable. CONCLUSION: In conclusion, the proposed checklist can reliably analyze the movement pattern of the dribbling with horizontal jumping throw – which can be highly useful for teachers and sports coaches.

Abstract Objective The study aimed to assess the reliability and validity of the IPOS-Pol for patient self-reporting. Method Patients (>18 years of age) with advanced cancer admitted to three palliative care centers (inpatient units and home-based) were recruited to a multicenter, cross-sectional, observational, prospective study. Participants provided responses to the IPOS-Pol Patient version and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 15 – Palliative Care (EORTC QLQ-C15-PAL) Polish version at baseline (T1) and four to seven days later (T2). We assessed test–retest reliability, internal consistency, and construct validity of the tool. Results One hundred and eighty patients were included. Test–retest reliability demonstrated no statistically significant differences in the average outcomes of the IPOS-Pol between T1 and T2 (27.2 ± 9.2 vs. 26.5 ± 8.7; p > 0.05). The intra-class correlation coefficient between T1 and T2 was r = 0.83 (p < 0.0001), the intra-class correlation coefficient for test–retest reliability of the IPOS-Pol items ranged from 0.63 to 0.84 (p < 0.0001), and the Cronbach's α coefficient for internal consistency was 0.773. The correlation coefficient between the IPOS-Pol and EORTC QLQ-C15-PAL total score was 0.79 (p < 0.001). Significance of results The patient version of the Polish adaptation of IPOS is a valid and reliable outcome measure for assessing symptoms and concerns of individuals receiving palliative care, as well as the quality of care provided.

The aim of this study was to estimate the reproducibility related to the presence and to the measurements of elongated styloid process (ESP), based on panoramic radiographs and the prevalence of ESP. Experimental design: one hundred sixty six panoramic radiographs were used, from edentulous patients from the Radiology Clinic files, at Araraquara Dental School, Unesp, during a four-year period. One hundred and twenty one were female and 45 were male. Two calibrated observers evaluated the radiographs. A caliper was used to measure, in mm, the ESP from the base of the temporal bone to the tip of the structure. The ESP was considered present when the measurements were 30mm or more. Kappa statistics (k ) and intra-class correlation coefficient (r ), were applied to estimate the reproducibility. The results showed that related to the presence of ESP, the interobserver agreement was k =0.85. Related to the measurements of ESP, the interobserver agreement was r =0.52. The prevalence of ESP was estimated in 12.6%. ESP distribution in females was similar to that for males. In conclusion, we found a greater level of agreement when observers evaluated the presence of ESP than when they did the measurement of ESP. The prevalence of ESP was 12.6%.

This systematic literature review evaluated the methodological quality of studies measuring noise in neonatal intensive care units. A manual and also electronic search in the Medline, Scielo, Lilacs, BDENF, WHOLIS, BDTD, Science Direct, NCBI and Scirus databases resulted in 40 studies that met the criterion "measuring noise in neonatal units and/or incubators". Experts in neonatology and acoustics validated the critical analysis instrument, which obtained a mean = 7.9 (SD=1.3). The inter-observer reliability in 18 articles resulted in an Intra-class correlation coefficient (ICC) of 0.89 (CI 0.75-0.95). The quality indicators were 50% better in those studies that measured noise only in the unit's environment and associated measuring strategies to the physical area. The results showed great methodological variability, which hindered comparability and raised the probability of bias. The conditions required to ensure internal and external validity were observed in few studies.

Background: The Walking Impairment Questionnaire (WIQ) is a short, easy to complete, disease-specific questionnaire to assess intermittent claudication. A Spanish version of the WIQ for Hispanic Americans has recently been validated in Texas, but it needs to be validated for European Spanish people. Patients and methods: After translation and cultural adaptation of the WIQ, 920 patients with intermittent claudication (ankle brachial index < 0.9) completed two questionnaires (Spanish version of the WIQ and European Quality of Life 5 Dimension [EQ-5D]). The validity of the WIQ was determined by correlating WIQ and EQ-5D. Test-retest reliability and internal consistency were determined using the intra-class correlation coefficient (ICC) and Cronbach’s alpha, respectively. Results: The three domains of the WIQ were moderately correlated with the EQ-5D health outcome (r = 0.54 to 0.60; p < 0.001). Test-retest reliabilities ranged from ICC = 0.89 to 0.91 and internal consistency (Cronbach’s alpha = 0.92) was high. Conclusions: The Spanish version of the WIQ for European Spanish patients was valid and reproducible, suggesting that it could be used in Spanish patients with intermittent claudication.

OBJECTIVE: The quality of paediatric clinical practice guidelines (CPGs) for the management of Mycobacterium tuberculosis infection is unclear. We aimed to comprehensively assess the quality of these CPGs and identify areas requiring improvement.DESIGN: CPGs were systematically searched and identified before being appraised by independent reviewers using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) and Reporting Items for Practice Guidelines in HealThcare (RIGHT) tools. Inter-rater reliability was assessed using intra-class correlation coefficient (ICC).RESULTS: Twenty-five CPGs were evaluated. All CPG agreements among four reviewers were good (ICC 0.753–0.939). The mean CPG score was 50.5% (23.5–78.4%), and seven CPGs were recommended for use. The mean scores of three domains were low: 38% for stakeholder involvement (5.6–93.1%), 38.4% for rigour of development (1–97.4%) and 36.3% for applicability (12.5–64.6%). The mean reporting rate of Reporting Items for Practice Guidelines in HealThcare fields was 41.8%, and the evidence field had the highest reporting rate (63.1%), while the review and quality assurance field had the lowest rate (15.4%) for CPGs that include methods.CONCLUSION: The methodological and reporting quality of the CPGs was variable and poor, respectively. More effort is needed in stakeholder involvement, rigour of development, applicability domains and reporting to produce higher-quality CPGs.

Background: A force platform must have validity and reliability for optimal use. The objective of this study was to analyze the validity and the reliability of the Satel 40 Hz stabilometric force platform. Methods: A study of instrumental validity and reliability, involving a cross-sectional correlational and comparative analysis was performed. To determine the validity, four certified weights located on three axes were used and the ability of the stabilometric force platform to detect changes in the position of the different axes was observed. A test–retest was performed to analyze the reliability. Forty-two symptom-free volunteers participated in the study. Assessments were taken in a standing static position and in a dynamic position, with the eyes open and closed. Three measurements were taken and the intra-class correlation coefficient (ICC) was calculated. Results: The validity increased as the weight increased for all the variables measured in the stabilometric parameters (p < 0.05). The reliability was shown to be good to excellent for the two visual conditions. The positional variables obtained a higher ICC. The variable with the best ICC was the Y mean in OE (ICC 0.874 and a p < 0.001). All the values showed an increase in a dynamic situation. Conclusion: The findings support the reliability and validity of the Satel 40 Hz stabilometric force platform. The platform could be recommended to evaluate static and dynamic standing balance in healthy adult individuals. Guidelines for treatment and the level of quality of stabilometry could be obtained from its use.

AbstractObjective:To determine the level of agreement between the American (Chilean) and British food composition tables in estimating intakes of macronutrients and antioxidants.Design, setting and subjects: Information based on a food-frequency questionnaire with emphasis on antioxidants was collected from 95 Chileans aged 24–28 years. Nutritional composition was analysed using the British table of food composition and the American table of food composition modified by Chilean food items. Mean differences and limits of agreement (LOAs) of estimated intake were assessed.Results:Mean differences between the two tables of food composition ranged from 5.3% to 8.9% higher estimates when using the American (Chilean) table for macronutrients. For micronutrients, a bias towards a higher mean was observed for vitamin E, iron and magnesium when the American (Chilean) table was used, but the opposite was observed for vitamin A and selenium. The intra-class correlation coefficient (ICC) ranged from 0.86 (95% confidence interval (CI) 0.81–0.91) to 0.998 (95% CI 0.995–1.00), indicating high to excellent agreement. LOAs for macronutrients and vitamins A and C were satisfactory, as they were sufficiently narrow. There was more uncertainty for other micronutrients.Conclusion:The American table gives relative overestimates of macronutrients in comparison to the British table, but the relative biases for micronutrients are inconsistent. Estimates of agreement between the two food composition tables provide reassurance that results are interchangeable for the majority of nutrients.
