An Item Response Theory analysis of the Unified Multiple System Atrophy Rating Scale

IntroductionThe Unified Multiple System Atrophy Rating Scale (UMSARS) has four subscales that have been specifically designed for the clinical assessment of MSA patients. UMSARS I (activities of daily living) and II (motor examination) subscales are regularly used as primary endpoints in treatment trials. The main objective of this study was to identify UMSARS I and II subscale items that best describe progression over time. MethodsAll MSA patients seen at the French Reference Centre for MSA from 2007 to 2020 were included in a prospective cohort with an annual follow-up assessment including UMSARS. The repeated measures of the 26 UMSARS I and II items were analyzed using a longitudinal Item Response Theory model to identify the most informative items for each of the five UMSARS IV disease stages. Sample size estimates were further calculated for the most informative items as a group. ResultsA total of 557 MSA patients were included with a mean follow-up of 2.3 years. The majority of items progressed with disease duration or across the different UMSARS IV disability stages, with the exception of those related to dysautonomia. Roughly 70% of the scale information was carried by only 11/26 items, many reflecting the patient perspective. These yielded similar sample size estimates than UMSARS I + II items. ConclusionThis study provides important information about the progression of UMSARS I and II subscale items. Improvements seem particularly necessary regarding those assessing dysautonomia. A shortened scale may be useful as outcome for future clinical trials.

Affective symptom dimensions in early-onset psychosis over time: a principal component factor analysis of the Young Mania Rating Scale and the Hamilton Depression Rating Scale.

Early-onset psychosis (EOP) is a complex disorder characterized by a wide range of symptoms, including affective symptoms. Our aim was to (1) examine the dimensional structure of affective symptoms in EOP, (2) evaluate the predominance of the clinical dimensions and (3) assess the progression of the clinical dimensions over a 2-year period. STROBE-compliant prospective principal component factor analysis of Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale-21 (HDRS-21) at baseline, 6-months, 1-year and 2-year follow-up. We included 108 EOP individuals (mean age = 15.5 ± 1.8years, 68.5% male). The factor analysis produced a four-factor model including the following dimensions: mania, depression/anxiety, sleep and psychosis. It explained 47.4% of the total variance at baseline, 60.6% of the total variance at 6-months follow-up, 54.5% of the total variance at 1-year follow-up and 49.5% of the total variance at 2-year follow-up. According to the variance explained, the mania factor was predominant at baseline (17.4%), 6-month follow-up (23.5%) and 2-year follow-up (26.1%), while the depression/anxiety factor was predominant at 1-year follow-up (23.1%). The mania factor was the most stable; 58.3% items that appeared in this factor (with a load > 0.4) at any time point appeared in the same factor at ≥ 3/4 time points. Affective symptoms are frequent and persistent in EOP. Mania seems to be the most predominant and stable affective dimension. However, depression and anxiety may gain predominance with time. A comprehensive evaluation of the dimensional structure and the progression of affective symptoms may offer clinical and therapeutic advantages.

Analysis of Concordance Between Parent Proxy and Child Self-report of KIDSCREEN-10 Health-related Quality of Life Questionnaire in an Elementary School-based Wellness Program: A Pilot Focus Group Study

Background: Researchers have previously commenced examining the degree of concordance between parent proxy and child self-reports on health-related quality of life (HRQOL) of many disease and impairment populations. Objects: To explore the differences between parent proxy and child self-reports on the HRQOL using Korean version of KIDSCREEN-10 questionnaires for applying to elementary school children and their parents who participated for a school-based wellness program. Methods: The focus groups were recruited for a school-based wellness program by implementing the following wellness services: 1) referring to a screening session for detecting potential posture-related musculoskeletal problems and 2) recommending home exercise programs. Before a primary field testing for the program, two focus groups were formed with a group of 9 parents and their 9 elementary school children aged 8-10 years of age. The parent proxy and child self-report versions of KIDSCREEN-10 questionnaires were administered to both groups after completion of the wellness program. Item level Rasch rating scale analysis was applied to compute logit scales of KIDSCREEN-10 questionnaire. Intraclass correlation coefficients (ICCs) and scatterplot of item difficulty between two reports were analyzed. Results: For fit statistics of parent proxy report, all items except 4 items (i.e., psychological well-being, mood/emotions, self-perception, parent relation) were found to be acceptable. For fit statistics of child self-report, all items except 3 items (i.e., psychological well-being, autonomy and home life) were acceptable. The relationship between two reports using ICCs were ranging from weak to very strong at p = 0.05 (i.e, ICCs = 0.011 to 0.905). Scatterplot analysis between two reports showed a major disparity on self-perception item at 95% confidence intervals. Conclusion: Both item level analyses and ICC comparisons provided a disparity between parent proxy and child self-reports of the HRQOL on self-perception item after competing a school-based wellness program. Therapist should consider the item as part of the HRQOL assessment.

Ultrasound pattern of anterolateral leg muscles in facioscapulohumeral muscular dystrophy.

To evaluate the degree of tibialis anterior (TA) and peroneus longus (PL) muscle involvement in facioscapulohumeral muscular dystrophy (FSHD) patients using ultrasound. We performed qualitative and quantitative assessments of muscle echogenicity, using Heckmatt's rating scale and gray scale analysis, respectively, in eight patients (five males, mean age 36.9±8.4years) with genetically confirmed FSHD 1. Both methods demonstrated a distinct pattern of preferential TA involvement and PL sparing in all FSHD patients, irrespective of the degree of muscle involvement. More specifically, echogenicity was higher in TA compared to PL according to Heckmatt score in the patient group (TA 3.43±0.49/PL 1.43±0.49, p<.001). In the gray-scale histogram, ranging from 0 (black) to 255 (white), the mean measurements of TA were significantly increased in patients compared to healthy (71.60±10.28 vs. 53.70±10.05, p=.012) and significantly higher than PL measurements in the patient group, but not in healthy subjects (p-values .012 and .779, respectively). A strong correlation between TA hyperechogenicity and muscle weakness was demonstrated in patients with mild-to-moderate weakness, but not in patients with severe weakness (r=-.949 and r=.644, respectively). This study shows a consistent US pattern of proximal anterolateral leg muscle involvement in FSHD, in agreement with findings of MRI studies and suggests that anterolateral leg muscle US may be a practical, fast and low-cost alternative to MRI.

Global versus task-specific postoperative feedback in surgical procedure learning

BackgroundTask-specific checklists and global rating scales are both recommended assessment tools to provide constructive feedback on surgical performance. This study evaluated the most effective feedback tool by comparing the effects of the Observational Clinical Human Reliability Analysis (OCHRA) and the Objective Structured Assessment of Technical Skills (OSATS) on surgical performance in relation to the visual-spatial ability of the learners. MethodsIn a randomized controlled trial, medical students were allocated to either the OCHRA (n = 25) or OSATS (n = 25) feedback group. Visual-spatial ability was measured by a Mental Rotation Test. Participants performed an open inguinal hernia repair procedure on a simulation model twice. Feedback was provided after the first procedure. Improvement in performance was evaluated blindly using a global rating scale (performance score) and hand-motion analysis (time and path length). ResultsMean improvement in performance score was not significantly different between the OCHRA and OSATS feedback groups (P = .100). However, mean improvement in time (371.0 ± 223.4 vs 274.6 ± 341.6; P = .027) and path length (53.5 ± 42.4 vs 34.7 ± 39.0; P = .046) was significantly greater in the OCHRA feedback group. When stratified by mental rotation test scores, the greater improvement in time (P = .032) and path length (P = .053) was observed only among individuals with low visual-spatial abilities. ConclusionA task-specific (OCHRA) feedback is more effective in improving surgical skills in terms of time and path length in novices compared to a global rating scale (OSATS). The effects of a task-specific feedback are present mostly in individuals with lower visual-spatial abilities.

Development and validation of the prenatal activity restriction stress questionnaire: a Rasch rating scale analysis

BackgroundAntepartum activity restriction (AAR) is a common recommendation given to women at risk for preterm delivery. However, such treatment has been shown to cause heavy emotional burdens on the women receiving it since it requires them to face many challenges derived from the intervention. Nevertheless, current existing scales lack effective items that can reflect the distress of these women. The aim of this study was to develop a reliable instrument to assess the distress of women experiencing AAR.MethodThe Prenatal Activity Restriction Stress Questionnaire (PARSQ) was developed according to comprehensive literature review, women’s interviews, and existing pregnancy-special stress scales from August 2016 to July 2017 in southern Taiwan. Six experts evaluated its content validity; the Rasch rating scale model (RSM) was used to examine its item-fit, dimensionality, and reliability with 200 women with AAR experience. Furthermore, the concurrent validity was assessed through computing the correlation of AAR women’s scores on the PARSQ and Perceived Stress Scale (PSS), and discriminant validity of the PARSQ was assessed to compare the scores’ differences between the AAR women and the healthy pregnant women.ResultsThe PARSQ was constructed with 23 items in the 4-dimensional scale: Role function changes (8 items), Fetal safety and health (5 items), Physical and psychological care issues (5 items), and Socioeconomic and medical issues (5 items). It was confirmed to have satisfactory content vitality (CVI = 0.78 to 1.0), reasonable item-fit (0.77 to 1.51), and good reliability in RSM model, as well as adequate concurrent validity (p = 0.005) and discriminant validity (p < 0.001).ConclusionsUnderstanding the distress of women undergoing AAR is necessary for developing appropriate prenatal care to assist women in coping with their situation to alleviate their emotional burdens. The developed PARSQ with satisfied psychometric properties can be an informative instrument for clinicians/researchers to assess the specific stress of pregnant women with AAR.

A psychometric evaluation of the Ethical Leadership Scale using Rasch analysis and confirmatory factor analysis

The purpose of the study was to psychometrically characterize the Ethical Leadership Scale (ELS) through confirmatory factor analysis (CFA) and Rasch analysis. Data were collected from 469 teachers across several countries. The one-factor structure of the ELS was confirmed in CFA. Rating scale diagnosis, item fit assessment, reliability analysis, unidimensionality, local independence, and differential item functioning (DIF) analyses were conducted using the Rasch Rating Scale Model. Item and rating scale analyses indicated that the ten items and five-category scale performed as intended. High person separation and reliability statistics supported the consistency of the ELS scores. Only one item (Item 4) demonstrated misfit in the Rasch model and two items (i.e., Items 2 and 10) showed DIF across Turkish and European respondents. None of the items showed DIF across gender. Overall CFA and Rasch models provided evidence for the psychometric quality of the 10-item ELS. However, reassessment of the scale after removing Item 4 showed improvement in the psychometric properties of the scale.

The unidimensionality of evil: A rating scale analysis of the short dark triad

Although only moderately correlated, Psychopathy, Machiavellianism, and subclinical narcissism can overlap to a higher degree in the case of brief measures. To reconcile shortness and unidimensionality, such inventories might emphasize less specific and more general components in their trait scale compositions. In the current study, we combined confirmatory factor analysis and the unidimensional Rating Scale model to investigate the salience of a general factor in the Short Dark Triad (SD3; Jones & Paulhus, 2014). Participants were 1965 community adults, with ages ranging from 18 to 72 years (M = 25.50, SD = 9.04). The results revealed that the true score variance contained in the SD3 scales is mostly due to a common dark triad component, whereas the coverage of content that is unique to each factor is relatively small. Although a substantive interpretation is presented regarding this single latent continuum underlying the SD3 items, future studies should attempt to test how sound this general factor is once the variation due to social desirability is controlled for. The issues of personality “nuances” and multidimensionality are also discussed.

Multidimensional PROMIS Self-Efficacy Measure for Managing Chronic Conditions

This study used a multidimensional categorical model to concurrently estimate individual’s self-efficacy for managing their chronic conditions across five related domains measured with the Patient-Reported Outcomes Measurement Information System Self-Efficacy Measure for managing chronic conditions (PROMIS-SE). A total of 1087 individuals with chronic conditions was analyzed in this study. A Diagnostic Classification Model (DCM) was applied to PROMIS-SE’s 4-item short forms measuring five behavioral domains (daily activities, emotions, medications and treatments, social interactions, and symptoms) to provide patient multidimensional categorical outcomes (high, transition, or low self-efficacy). Psychometric properties were examined using classification consistency, model fit, entropy value, domain and item-level information, and patient profiles. DCM PROMIS-SE showed adequate classification consistency, fit, and high entropy values. Five domains demonstrated different average probabilities of having high self-efficacy for patients with chronic conditions from 42.0% (emotions) to 70% (medications and treatments). Rating scale analysis indicated the rating 5 (very confident) most critically discriminated patients with high or low self-efficacy for managing chronic conditions across all domains. Only four common patient profile groups contained more than 5% of the sample. Acceptable psychometric properties indicate that DCM PROMIS-SE satisfactorily classified patients with chronic conditions. This study demonstrates a feasible approach for other existing multidimensional measures to classify patients’ conditions and support clinical judgment.

초등학교 교사의 형성적 피드백 실행 척도 개발 및 타당화

The purpose of this study was to develop the formative feedback practice scale for elementary school teachers and to test its reliability and validity. Semi-structured questionnaire surveys, interviews and discussions yielded 50 pilot items. These items were administered elementary school teachers and the data from 409 teachers were analyzed through Rasch rating scale analyses, confirmatory factor analyses, correlation analyses. The Rasch model was applied to each of the 6 formative feedback practice factors(i.e., planning, process, questioning, improvement, encouragement, and self-regulation). The results from confirmatory factor analyses indicated that the first-order five-factor model showed reasonable fit. Thus, the formative feedback practice scale for elementary school teachers consisted of planning scaffolding(4 items), process scaffolding(6 items), improvement monitoring(4 items), encouragement monitoring(4 items), and self-regulation monitoring(4 items). Internal consistency reliabilities of the sub-scales were high, and positive correlations among the sub-scales were statistically significant. The 5 sub-scales of the formative feedback practice scale for elementary school teachers were positively correlated with the sub-scales of the assessment for learning questionnaire(short-form) and the conceptions of assessment scale. The formative feedback practice scale for elementary school teachers may be useful for measuring and assessing elementary school teachers’ feedback practice in the classroom.
