Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants’ mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient – ICC = 0.991–0.999) and good intra-rater reliability (ICC = 0.997–1.0), and there was excellent internal consistency (Cronbach's α = 0.937–0.999). The instrument’s factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

Abstract Context: Measurement of patient-centred outcomes enables clinicians to focus on patient and family priorities and enables quality of palliative care to be assessed.Objectives: This study aimed to evaluate the validity and reliability of the English and translated Chinese IPOS among advanced cancer patients in Singapore.Methods: IPOS was forward and backward translated from English into Chinese. Structural validity was assessed by confirmatory factor analysis; known-group validity by comparing inpatients and community patients; construct validity by correlating IPOS with Edmonton Symptom Assessment System-revised (ESAS-r) and Functional Assessment of Cancer Therapy–General (FACT-G); internal consistency by Cronbach’s alpha; inter-rater reliability between patient and staff responses; test-retest reliability of patient responses between two timepoints.Results: 111 English-responding and 109 Chinese-responding patients participated. The three-factor structure (Physical Symptoms, Emotional Symptoms and Communication and Practical Issues) was confirmed with Comparative Fit Index and Tucker-Lewis-Index > 0.9 and Root Mean Square Error of Approximation < 0.08. Inpatients scored higher than outpatients as hypothesised. Construct validity (Pearson’s correlation coefficient, r≥|0.608|) was shown between the related subscales of IPOS and FACT-G and ESAS-r. Internal consistency was confirmed for total and subscale scores (Cronbach's alpha ≥ 0.84), except for the Communication and Practical Issues subscale (Cronbach’s alpha = 0.29–0.65). Inter-rater reliability (Intra-class correlation coefficient [ICC] ≤ 0.43) between patient and staff responses was insufficient. Test-retest reliability was confirmed with Intra-class correlation coefficient ICC = 0.80 (English) and 0.88 (Chinese) for IPOS Total.Conclusion: IPOS in English and Chinese showed good validity, good internal consistency, and good test-retest reliability, except for the Communication and Practical Issues subscale. There was poor inter-rater reliability between patients and staff.

Introduction: The objective of this study was to adapt the Brazilian version, and verify the validity, reliability and internal consistency of the Oliveira questionnaire on low back pain in young people.Material and Methods: The questionnaire was translated from European Portuguese into Brazilian Portuguese by means of translation and re-translation. The validity of the contents was determined by experts who analyzed the clarity and pertinence of the questions. Fifteen young people aged 15 to 18 took part in the pre-test step (qualitative analysis), 40 in the test-retest (reliability) and 679 in the evaluation of internal consistency. The intra-class correlation coefficient and Spearman’s correlation coefficient were used in the reliability analysis (test-retest), and Cronbach’s alpha to determine the internal consistency (stability).Results: In the translation phase the questionnaire was modified and considered suitable, observing similarity and equivalence of the two versions. After being corrected by the experts in the validation of the contents, the instrument was considered suitable and valid, and in the pre-test, the young people suggested some modifications to make the questionnaire more succinct. With respect to reliability, the values for the intra-class correlation coefficient were between 0.512 – acceptable and 1 – excellent and Spearman’s correlation coefficient varied between 0.525 and 1, classifying the instrument as reproducible. The internal consistency was considered acceptable with a 0.757 Cronbach’s alpha.Discussion: The Oliveira questionnaire was choosen since it has been used in several Portuguese studies; moreover, it addresses the need to raise data regarding low back pain and associated risk factors.Conclusions: The Brazilian version of the Oliveira questionnaire on low back pain in young people showed valid and reliable cultural adaptation, with good reliability and stability.

Abstract Background/Introduction. Recently the central role of hemodynamic invasive monitoring during MitraClip (Abbott Vascular, Santa Clara, CA, USA) procedure has been raised. After removal of Steerable Guide Catheter (SGC) at the end of procedure, iatrogenic interatrial septum defect determines acute sub-clinical hemodynamic changes depending on right atrial (RA) and left atrial (LA) pressures. The possibility to assess LAP non-invasively by Doppler -echocardiography at the end of the procedure allows to quantify real hemodynamic impact of reduction of MR and leaves the door open to further therapeutic decisions (such as closure of iatrogenic IASd). Purpose This prospective study aimed to assess the role of evaluation of post-procedural mean trans-atrial gradient with continuous-wave (CW) Doppler (DPmean-IAS) in estimating final m-LAP after removal of SGC. Methods We prospectively performed the computation of trans-atrial CW- Doppler tracing for estimation of mean-transatrial gradient (meanGp-LA-RA) in patients treated with MitraClip; we added the estimation of central venous pressure (CVP) according to: i) dilatation of superior vena cava (IVC, mm); ii) presence or not of systolic excursion of IVC (end-inspiratory excursion was not evaluable in patients under sedation); iii) hepatic vein dilatation. The sum of CVP estimated and meanGp-LA-RA (mmHg) represents the m-LAP-Echo-measured at the end of procedure. This value has been compared with m-LAP measured invasively before removal of SGC. We tested the inter-rater reliability with the Intra-class Correlation Coefficient for comparing this method with the gold standard (invasive assessment of LAP). Results we included 19 patients; aetiology of MR was degenerative in 89% of cases. Basal m-LAP was 15 ± 13,3 mmHg and decreased by 32% by the end of procedure (mean-LAP at the end: 10,1 ± 3,3 mmHg, p &lt; 0.001). At the end of the procedure mean Gp-LA-RA was 2.5 ± 1.2 mmHg and CVP 7.5 ± 3.5; the m-LAP-Echo-measured was 9.6 ± 2.4. The delay in time of computation of m-LAP by echocardiography with respect to last invasive assessment available was computed and settled around 5 minutes (IQR 3-9 min). The inter-rater reliability with the Intra-class Correlation Coefficient was high: 0.8, (CI95% 0.647-0.948, p &lt; 0.01); with Bland-Altman test we could assess that bias of measures was acceptable for this clinical context with upper concordance limit of 2,7 mmHg and lower of 4,7 mmHg, with a bias of 0,9 mmHg, not relevant for this clinical purpose. Conclusions The present study represents the first validation of a Doppler-based method for non invasively assessing post-procedural LAP in percutaneous mitral valve interventions requiring transeptal approach. Follow up is needed for correlate this value with clinical outcomes.

Introduction: The Exercise Self-Efficacy scale (ESES) is a reliable measure, in the English language, of exercise self-efficacy in individuals with spinal cord injury. The aim of this study was to culturally adjust and validate the Exercise Self-Efficacy scale in the Portuguese language.Material and Methods: The Exercise Self-Efficacy scale was applied to 76 subjects, with three-month intervals (three applications in total). The reliability was appraised using the intra-class correlation coefficient and Bland-Altman methods, and the internal consistency was evaluated using Cronbach´s alpha. The Exercise Self-Efficacy scale was correlated with the domains of the Quality of life Questionnaire SF-36 and Functional Independence Measure and tested using the Spearman rho coefficient.Results: The Exercise Self-Efficacy scale-Brazil presented good internal consistency (alpha 1 = 0.856; alpha 2 = 0.855; alpha 3 = 0.822) and high reliability in the test-retest (intra-class correlation coefficient = 0.97). There was a strong correlation between the Exercise Self-Efficacy scale-Brazil and the SF-36 only in the functional capacity domain (rho = 0.708). There were no changes in Exercise Self-Efficacy scale-Brazil scores between the three applications (p = 0.796).Discussion: The validation of the Exercise Self-Efficacy scale questionnaire permits the assessor to use it reliably in Portuguese speaking countries, since it is the first instrument measuring self-efficacy specifically during exercises in individuals with spinal cord injury. Furthermore, the questionnaire can be used as an instrument to verify the effectiveness of interventions that use exercise as an outcome.Conclusion: The results of the Brazilian version of the Exercise Self-Efficacy scale support its use as a reliable and valid measurement of exercise self-efficacy for this population.

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.

Maximal aerobic capacity (VO2 max) is one of the important factors that influence swimming performance. Currently, the Garmin Forerunner Fitness Watch 935 used to measure VO2 max are expensive, require skilled-trained personnel, not feasible for large-scale use, and land-based, which will not be accurate in measuring water-based activity. In order to measure the swimming performance, there is a need for an affordable, feasible, and reliable device. Therefore, the current study aimed to examine the intra-rater reliability of Garmin Forerunner Fitness Watch 935 accuracy in measuring the VO2 max among collegiate swimmers during the 200m swimming task. The VO2 max measurement of 10 collegiate swimmers was taken with Garmin Forerunner for two trials. The intra-class correlation coefficient (ICC), standard error of measurements (SEMs), and Bland-Altman plot was used in the current study to establish the inter-rater reliability measurement. The intra-rater reliability of Garmin Forerunner showed high reliability and accuracy with an intra-class correlation coefficient (2,1) of 0.869 and standard error of measurements of 0.231 ml/kg/min. Further, the results were strengthened with Bland-Altman plot showed an acceptable agreement between the two trials. The Garmin Forerunner would be a simple, objective and useful device to be used by physiotherapists, trainers and other sports-related disciplines to assess and improve the swimming performance by targeting the heart rate and VO2 max.

Abstract Objectives To investigate the reliability of durometry in systemic sclerosis (SSc), by means of a systematic review and additional pilot study. Methods Literature was systematically reviewed according to the PRISMA guidelines to identify all original studies assessing the reliability of durometry in SSc. Additionally, in the pilot study, intra-rater reliability was evaluated in a first cohort of 74 SSc patients (61 female, 13 LSSc/53 LcSSc/8 DcSSc). In a second separate set of 30 SSc patients (21 female, 4 LSSc/20 LcSSc/6 DcSSc), intra- and inter-rater reliability were evaluated. Results Only two unique records identified through the systematic review were qualified to generate conclusions. Regarding intra-rater reliability, Kissin reported excellent intra-class correlation coefficient values (ICC, 0.86–0.94) for measurements at nine skin sites in two DcSSc patients. Merkel and Kissin described, both in five DcSSc patients, good to excellent inter-rater reliability (ICC, 0.82–0.96 and 0.61–0.85) for measurements at respectively, six and nine skin sites. In our pilot study, ICC for intra-rater reliability at 17 standardized skin sites were excellent in both cohorts, ranging 0.93–0.99 and 0.78–0.98, respectively. ICC for inter-rater reliability at 17 standardized skin sites were good to excellent 0.63–0.93, except for the feet (0.48 and 0.52). Conclusion The preliminary findings in the literature are supported by our pilot study in which we have attested the reliability of durometry in SSc patients. However, prior to including durometry as an (additional) outcome measure in SSc clinical trials, its validation status in the assessment of skin fibrosis needs to be completely attested.

ABSTRACT: The development and validation of a standard area diagram set (SADs) was proposed in this study to assess the severity of powdery mildew (Podosphaera xanthii) in watermelon (Citrullus lanatus) leaves. The SADs proposed has twelve levels of severity, varying from 0.07 to 100%. The SADs were validated by 16 raters who had no previous experience in evaluating plant disease severity. Initially, the estimation of severity was performed without the use of the SADs in leaves with different levels of severity. In a second moment, the same raters estimated the disease severity using the SADs proposed. By Lin’s concordance correlation analysis, there was an improvement in precision (coefficient of correlation, r = 0.878 and r = 0.959, without and with SADs, respectively) and accuracy (bias correction factor, Cb = 0.830 and 0.982, without and with SADs, respectively) using SADs when compared to the non-use of SADs. The agreement (Lin’s concordance correlation coefficient, ρc = 0.734 and 0.952 without and with SADs, respectively) also improved using SADs. Severity estimates inter-rater were more reliable when using SADs (coefficient of determination, R2 = 0.681 without and R2 = 0.864 with SADs; Intra-class correlation coefficient, ρ = 0.759 and ρ = 0.928, without and with SADs, respectively). Therefore, SADs improved precision, accuracy and reliability of powdery mildew severity on watermelon leaves.

Background: The inter-rater reliability of the craniocervical flexion test (CCFT) has not been established. Objective: To investigate the intra-rater and inter-rater reliabilities of the CCFT in asymptomatic subjects. Methods: Sixty asymptomatic subjects were randomly selected for the study. The CCFT was measured on each subject by two testers for inter-rater reliability and by one of the testers after a gap of seven days for the intra-rater reliability. Before testing, the participants were trained for the movement and compensations were corrected. Results: The CCFT has high inter-rater reliability (intra-class correlation coefficient [Formula: see text] 0.907, standard error of mean [Formula: see text] 0.735) and high intra-rater reliability (intra-class correlation coefficient [Formula: see text] 0.986, standard error of mean [Formula: see text] 0.287). A Bland & Altman limits of agreement analysis has confirmed the high inter- and intra-rater reliabilities of the test. Conclusion: The CCFT has high inter-rater and intra-rater reliabilities in asymptomatic subjects.

Microaggressions are daily insults to minority individuals such as people with disabilities (PWD) that communicate messages of exclusion, inferiority, and abnormality. In this study, we developed a new scale, the Ableist Microaggressions Impact Questionnaire (AMIQ), which assesses ableist microaggression experiences of PWD. Data from 245 PWD were collected using Amazon’s Mechanical Turk (MTurk) platform. An exploratory factor analysis of the 25-item AMIQ revealed a three-factor structure with internal consistency reliability ranging between .87 and .92. As a more economical and psychometrically sound instrument assessing microaggression impact as it pertains to disability, the AMIQ offers promise for rehabilitation counselor research and practice.
