Objective: To assess the psychometric properties of the Spanish King's Parkinson's Disease Pain Scale (KPPS). Design: A descriptive transversal study at a Spanish hospital. Methods: Fifty‐three Parkinson's disease (PD) patients suffering from otherwise explained pain (34 females, age = 63.42 ± 10.52 years, time with disease = 7.25 ± 4.65 years) were evaluated by the KPPS, Brief Pain Inventory (BPI), two Pain Pressure Thresholds (PPTs), Widespread Mechanical Hyperalgesia (WMH), and Conditioned Pain Modulation (CPM). A retest of the KPPS was performed 7–15 days later. Internal consistency, test–retest reliability (intraclass correlation coefficient (ICC)), measurement error, factor structure, and criterion/convergent validity were assessed. Results: Internal consistency of the Spanish KPPS was acceptable (Cronbach's alpha = 0.77). The mean test and retest total KPPS scores were similar (test = 34.83 ± 23.50 points, retest = 35.87 ± 26.23 points), and test–retest reliability was good (ICC = 0.85, 95% CI = 0.75–0.91). Standard error of measurement (SEM) was 9.1 points and smallest detectable change (SDC) was 25.22 points. The sampling adequacy was not sufficient to perform factor analysis. The total KPPS score was not correlated to the BPI intensity subscale (r = 0.18, p = 0.19), but it was moderately and positively correlated to the interference subscale (r = 0.43, p = 0.001). The total KPPS was moderately and negatively correlated to both the remote PPT (r = −0.4, p = 0.003) and WMH (r = −0.38, p = 0.005). No statistical correlations were found with local PPT or CPM. Conclusion: The present study provides evidence that the Spanish KPPS effectively measures pain in individuals with PD, with its total score demonstrating good reliability, minimal measurement error, and adequate criterion and convergent validity.

Introduction Movement quality screening in early-career military populations, like Army Reserve Officers' Training Corps (AROTC) cadets, could decrease the negative impact of musculoskeletal injury observed within the military. Movement quality screening techniques should be valid before being pursued in the field. Normative data describing movement quality of AROTC cadets are also needed. Therefore, the aims of this study were to determine criterion validity of several movement quality assessments and report normative jump-landing kinematics of AROTC cadets. Materials and Methods This cross-sectional research was approved by the Institutional Review Board. As part of a larger study, 20 AROTC cadets (21.3 ± 3.4 years; 1.7 ± 0.1 m; 73.8 ± 14.8 kg) had 3-dimensional (3D) and 2-dimensional (2D) kinematic data collected simultaneously while performing a jump-landing task. Variables of interest were 3D hip and knee sagittal, frontal, and transverse joint angles at maximum knee flexion. An experienced rater calculated sagittal and frontal 2D joint angles at maximum knee flexion. Averages of 2D and 3D angles were calculated to describe normative data and for further data analysis. Bivariate correlations between 3D and 2D variables were used to determine criterion validity. Results Moderate correlations were found between 2D and 3D hip frontal plane angles (P  = .05, r  =−0.33), 2D and 3D knee sagittal plane angles (P  = .04, r  = 0.35), and 2D and 3D knee frontal plane angles (P  = .03, r  = −0.36). Normative values of knee and hip kinematics demonstrated averages of 17.58° of knee adduction, 16.48° of knee external rotation, 11.57° of hip abduction, 10.76° of hip internal rotation, and 103.47° of knee flexion during landings. However, ranges demonstrated that landing patterns vary within AROTC cadets. Conclusions The normative values of 3D jump-landing kinematic data indicate that movement quality varies greatly within AROTC cadets, and some cadets display potentially injurious movements. Therefore, screening movement quality could be beneficial to determine musculoskeletal injury risk in AROTC cadets. Based on the correlations discovered in this study, we recommend the 2D techniques used in this study be researched further as they may serve as alternatives to expensive, timely 3D techniques that could be better utilized in military environments.

Standing pelvic tilt (PT) is related to biomechanics linked with increased risk of injury such as dynamic knee valgus. However, there is limited evidence on how standing PT relates to dynamic PT and whether the palpation meter (PALM), a tool to measure standing PT, is valid against 3-dimensional (3D) motion analysis. The purposes of this study were to (1) determine the criterion validity of the PALM for measuring standing PT and (2) identify the relationship between standing PT and dynamic PT during running. Participants (n = 25; 10 males and 15 females) had their standing PT measured by the PALM and 3D motion analysis. Dynamic PT variables were defined at initial contact and toe off. No relationship between the 2 tools was found. Significant large positive relationships between standing PT and PT at initial contact (r =.751, N = 25, P <.001) and PT at toe off (r =.761, N = 25, P <.001) were found. Since no relationship was found between standing PT measured by the PALM and 3D motion analysis, the PALM is not a valid alternative to 3D motion analysis. Clinicians may be able to measure standing PT and gain valuable information on dynamic PT, allowing clinicians to quickly assess whether further biomechanical testing is needed.

There is a need to investigate the diagnostic utility of autism diagnostic questionnaires in school-age children, who are increasingly being referred for autism assessment. Aside from the standardization sample, little research has been conducted on the Autism Spectrum Rating Scales, particularly regarding teacher reports. This study investigated the criterion validity of the Autism Spectrum Rating Scales-Teacher report for ages 6–18 (ASRS-T6-18) in a well-characterized community sample of 409 children (autism [AUT] n = 122; non-autism [NOT] n = 287; X ¯ age = 9.91) evaluated with the Autism Diagnostic Observation Schedule-2, a well-validated autism diagnostic measure. Significant mean differences with small to moderate effect sizes (d = 0.28–0.56) were observed for all scores except Self-Regulation, Adult interaction, and Attention. Logistic Regression and Receiver Operating Characteristic analyses conducted for the Summary, ASRS, and two Treatment scales (Peer and Social-Emotional Reciprocity) indicated low ORs (< |1.08|) and AUCs in the poor range (<.67). Total and Unusual Behavior emerged as comparatively stronger scales with covariates (age and IQ); other scales were generally similar with/without control variables. Sensitivity and specificity could not be optimized. The suggested 60 t -cutpoint had fair or good sensitivity (76.23–83.61) for all examined scales except Unusual Behavior (68.03). However, specificity was poor (46.93–54.36), with high false positive rates (45.64%–63.07%). In complex community samples, the ASRS-T6-18 behaves more like a screener as opposed to a diagnostic measure. [ABSTRACT FROM AUTHOR]

Objective: "Ecological validity" (EV) is classically defined as test's ability to predict real-world functioning, either alone or together with test's similarity to real-world tasks. In neuropsychological literature on assessment of executive functions (EF), EV is conceptualized inconsistently, leading to misconceptions about the utility of tests. The goal of this systematic review was to examine how EV is conceptualized in studies of EF tests described as ecologically valid. Method: MEDLINE and PsychINFO Databases were searched. PRISMA guidelines were observed. After applying inclusion and exclusion criteria, this search yielded 90 articles. Deductive content analysis was employed to determine how the term EV was used. Results: About 1/3 of the studies conceptualized EV as the test's ability to predict functional outcomes, 1/3 as both the ability to predict functional outcome and similarity to real-world tasks, and 1/3 were either unclear about the meaning of the term or relied on notions unrelated to classical definitions (e.g., similarity to real-world tasks alone, association with other tests, or the ability to discriminate between populations). Conclusions: Conceptualizations of the term EV in literature on EF assessment vary grossly, subsuming the notions of criterion, construct, and face validity, as well as sensitivity/specificity. Such inconsistency makes it difficult to interpret clinical utility of tests that are described as ecologically valid. We call on the field to require that, at minimum, the term EV be clearly defined in all publications, or replaced with more concrete terminology (e.g., criterion validity). [ABSTRACT FROM AUTHOR]

In recent years, some models for binary and graded format responses have been proposed to assess unipolar variables or "quasi-traits." These studies have mainly focused on clinical variables that have traditionally been treated as bipolar traits. In the present study, we have made a proposal for unipolar traits measured with continuous response items. The proposed log-logistic continuous unipolar model (LL-C) is remarkably simple and is more similar to the original binary formulation than the graded extensions, which is an advantage. Furthermore, considering that irrational, extreme, or polarizing beliefs could be another domain of unipolar variables, we have applied this proposal to an empirical example of superstitious beliefs. The results suggest that, in certain cases, the standard linear model can be a good approximation to the LL-C model in terms of parameter estimation and goodness of fit, but not trait estimates and their accuracy. The results also show the importance of considering the unipolar nature of this kind of trait when predicting criterion variables, since the validity results were clearly different.

Background and Purpose: This study aimed to develop and examine the psychometric properties of the "Preparedness for Transition to Survivorship Care Instrument" (PTSCI) for cancer survivors. Methods: A cross-sectional study of cancer survivors in Korea was conducted to test the reliability and validity of the PTSCI. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and concurrent validity tests were conducted. Results: The EFA showed that the 7-factor structure of a 34-item PTSCI accounted for 61.5% of the total observed variance. In CFA, three competing models were created and compared to a 7-factor solution model. A 6-factor 31-item model showed the best fit and was chosen as the final PTSCI model. PTSCI is significantly associated with quality of life, psychological distress, and health promotion. Conclusions: PTSCI can be helpful in preparing for diverse psychosocial and behavioral issues faced by cancer survivors in the survivorship phase. [ABSTRACT FROM AUTHOR]

Occupational Information Network (O*NET) is a comprehensive job analysis repository, developed and periodically updated in the U.S. The study aims to validate O*NET in the Australian context and illustrate the potential to use O*NET as a source of robust occupational research data internationally. We first link O*NET data at the occupational level with individual-level data in the Australian Workplace Barometer (AWB) database containing a sample of 3,829 individuals working in 209 occupations. We then conceptually replicate the primary hypothesized relationships from nine published studies that used O*NET ratings of four job characteristics (job hazards, emotional labour requirements, job autonomy, and task significance) to predict work-related outcomes. Specifically, we selected the same O*NET job descriptors used in the nine studies and linked them to similar but not identical employee outcomes obtained from the AWB database. Multi-level analyses showed that the hypothesized relationships were predominantly supported at the occupational level, demonstrating the criterion validity of the O*NET job characteristic profiles in the Australian context. Overall, our research highlights the potential to use O*NET in research and policy applications on a broader international scale, predicated on obtaining solid validation evidence.

BackgroundCommunities That Care (CTC) is an evidence-based community change strategy for supporting healthy youth development. One of its key elements is the development of a community profile to identify and prioritise risk factors for health and behavioural problems in adolescents based on the CTC Youth Survey. The strategy was originally developed and evaluated in the United States. An adapted version of the survey has been used in Germany since its first implementation in 2008. However, the dimensionality and validity of the adapted risk factor scales have not yet been evaluated. Therefore, this study aimed to confirm the assumed unidimensional structure and to establish the concurrent criterion validity of each risk factor.MethodsA sample of 1,911 adolescents attending grades six to eleven in Lower-Saxony, Germany, was used to evaluate 23 risk factor scales of the German CTC Youth Survey covering the domains peer/individual, family, school, and community. Confirmatory factor analysis was used to assess the dimensional structure of all risk factors with sufficient item numbers. Goodness of fit was determined using CFI, SRMR, and RMSEA. Latent regression analysis tested the concurrent criterion validity of all unidimensional risk factors. For this, violent and delinquent behaviour, substance use, and depressive symptomatology were regressed on each risk factor.ResultsAll evaluable risk factors demonstrated acceptable to good model fit regarding unidimensionality and predicted violent and delinquent behaviour, and substance use better than depressive symptomatology. Regarding the peer/individual risk factors, there are particularly high correlations with violent and delinquent behaviour, and substance use. In contrast, two risk factors were not correlated with substance use, whilst two other risk factors were not correlated with depressive symptomatology.ConclusionOverall, the results indicate that most risk factors demonstrate unidimensionality and are valid in terms of concurrent criterion validity. Although some risk factors were not correlated with every outcome, they still predicted most outcomes, suggesting that the CTC Youth Survey is a viable tool for communities to assess their community risk profile. Risk factors that did not demonstrate unidimensionality or concurrent criterion validity should be monitored in future surveys and interpreted with caution until further evidence is available.

The generalization of the results accumulated to date has shown that the implicit measures of attitudes (some even suggest defining them with a less pretentious term “indirect”) show a disappointingly weak predictive potential in relation to real behavior. Thus, the predictive validity of the Graphical Association Test of Attitude (GATA), which also claims to be an indirect method, has been questioned. To check this assumption, we analyzed the results obtained with GATA in 64 predictions provided that the predicted outcome could be verified by real action. Such forecasts cover the domains of electoral, consumer and communicative behavior. In some cases, the prediction based on the data from a representative sample was checked referring to the actual behavior of the group represented by the sample, e.g., the electorate, or the consumers of a certain category of goods, etc. In other cases, the accuracy of the forecast was checked for each respondent. This allows to avoid the effect of “mutual compensation” of erroneous forecasts with opposite valence. The test method consisted of a comparison of the prediction accuracy of pairs of “control” and “experimental” prediction models: the only difference identified was that the latter used the data from indirect measurements of GATA as an additional factor of action. In the article, all models are presented in their simplest and most transparent versions. The results of the conducted meta-analysis do not fully correspond to the general trend: the use of the GATA data significantly and continuously improves the accuracy of predicting behavior. In addition, the incremental effect on the accuracy of individual forecasts (for each respondent) turned out to be higher than that of the sample-based group forecasts.

Assessment centers (ACs) are one of the most common selection and recruitment methods in today's business world, with very high acceptance in practice. The AC research literature, however, has focused on managerial performance and neglected sales performance. Therefore, we assessed the features of ACs for sales positions. The results indicated that AC ratings designed for sales positions exhibited good interrater agreement and were distinct. The criterion-related validity of AC observer ratings was in the normal range of ACs designed for managerial jobs in terms of overall assessment rating scores. Additionally, we tested a new approach to ACs for salesperson selection based on the socioanalytic theory of personality. We hypothesized and found that motivation for sales success combined with social competence predicts field sales performance one year later. This interaction effect explained incremental variance in objective performance above and beyond exercises and overall assessment rating scores. Operational validity compared to the traditional approach increased by 25%. The true score criterion validity of the new approach was.49. We discuss implications and limitations.

The term "ecological validity" (EV) has traditionally referred to test scores' ability to predict real-world functioning. However, a test's similarity to real-world tasks is sometimes mistaken for evidence of its ability to predict daily life, sometimes bypassing rigorous validation research. The goal of this systematic review was to examine the type and quality of evidence used to support claims of EV of novel face-valid tests of executive functions (EF). MEDLINE and PsychINFO databases were searched using the following terms: ecologic* AND neuropsychol* AND (executive function* OR executive dysfunction OR executive abilit*). Thirty-two articles that explicitly stated that their results demonstrated EV of a novel face-valid test of EF were identified. Results showed that only 60% of studies based their claims about EV on test scores' ability to predict functional outcomes, with the remaining 40% relying on other evidence (e.g., correlations with other measures, participant feedback, group differences). Among the studies that did base their conclusions on test scores' ability to predict outcomes (n = 19), an overwhelming majority relied on behavioral rating scales, utilized small sample sizes and participant-to-variable ratios, and failed to control for covariates and multiple comparisons. Poor scientific rigor was particularly pronounced in studies of "naturalistic" tests. The present systematic review reveals significant conceptual, methodological, and statistical flaws among an overwhelming majority of studies that claim to have found support for the EV of a novel face-valid test of EF. We call upon authors, reviewers, and editors to safeguard the scientific rigor of research in this area. Public Significance Statement: This literature review reveals considerable inconsistency in the quality of evidence among neuropsychological studies that claim to have demonstrated "ecological validity" of tests designed to resemble real-world tasks and intended for use as predictors of patients' daily functioning. We call upon neuropsychologists to use clearer terminology and to avoid common pitfalls in this type of test development research to improve our field's ability to interpret results of neuropsychological evaluations.

This study explored the factor structure of the short form of the Teachers’ Sense of Efficacy Scale (TSES-Sf) using Confirmatory Factor Analysis (CFA), and Exploratory Structural Equation Modeling (ESEM), as well as bifactor models based on these two approaches. A total of 295 elementary level teachers (80% females) completed measures of interest for this research. The bifactor-ESEM model provided the best fit to the data. The data revealed that a strong general factor of teachers’ self-efficacy underpins responses to all TSES-Sf items, however, self-efficacy in student engagement and self-efficacy in classroom management had significant specificity after partialling out the general factor. On the other hand, self-efficacy in instructional strategies items loaded primarily on the general factor and showed low specificity over and above the general factor. This study reviews the previous conclusions about the criterion validity of TSES-Sf and proposes bifactor models as a useful framework for evaluating the structural validity of this scale.

Curriculum-based measures (CBMs), which allow educators to monitor progress over time and make instructional decisions based on student performance, represent a fixture of general approaches to reading and data-based instructional frameworks. However, evidence supporting the use of CBM for students with intellectual disabilities is limited. This study evaluated the criterion validity of a reading CBM battery. Multiple CBM and standardized criterion measures were administered to elementary-age children (N = 56) with intellectual disabilities. Inferential analyses identified numerous domain-specific correlations between CBM and criterion measures; however, no single CBM emerged as a more effective predictor of reading performance. Findings provide qualified support for the use of CBM with children who have intellectual disabilities. [ABSTRACT FROM AUTHOR]

Aim: The aim of this Swedish study was to evaluate the assessment of clinical signs of perceptual disorder in children with cerebral palsy (CP). Methods: Three experienced raters assessed 56 videos of 19 children from 1 to 18 years of age with bilateral spastic CP, which were recorded by colleagues at an Italian hospital. Six signs were evaluated for inter‐rater reliability and criterion validity. Clinical applicability was evaluated by assessing inter‐rater reliability between 47 Swedish clinicians, who examined 15 of the videos during face‐to‐face and online education seminars. There were 41 physiotherapists, two occupational therapists and four doctors, with 1–37 years of clinical experience and a median of 10 years. Results: The experienced raters demonstrated moderate to almost perfect inter‐rater reliability (kappa 0.54–0.81) and criterion validity (0.54–0.87) for startle reaction, upper limbs in startle position, averted eye gaze and eye blinking. The clinicians recognised these signs with at least moderate reliability (0.56–0.88). Grimacing and posture freezing were less reliable (0.22–0.35) and valid (0.09–0.50). Conclusion: Four of the six signs of perceptual disorder were reliably recognised by experienced raters and by clinicians after education seminars. Extended education and larger study samples are needed to recognise all the signs. [ABSTRACT FROM AUTHOR]

Objective: to develop and validate an abbreviated version of the EAT. Method: the sample consisted of 678 participants (318 from the control group and 360 from the clinical group). Results: adequate internal consistency of the instrument was observed (α=.89). The exploratory factorial analysis yielded three factors 1) Food restriction 2) Bulimic symptoms 3) Food and weight control. The structure was confirmed with the confirmatory analysis, presenting a good adjustment of the data: 1) significant Chi-square (X2(121)=699.05, p=.001), 2) GFI=.914 3) AGFI=.942 4) CFI=.953 5) RMSEA=.083 6) RMR=.043. The most suitable cut-off point value was 15. The convergent validity of the instrument was evaluated using the Eating Disorders Inventory (EDI), observing positive and significant correlations. Conclusion: this version of the instrument presents good validity and reliability properties. Clinical and theoretical implications are discussed. [ABSTRACT FROM AUTHOR]

Recent evidence suggests that personality could play just as important a role in the prediction of important work-related outcomes as cognitive ability. However, it might be meaningful to adjust the level at which personality is measured and reported, depending on the narrowness of the scope of the criteria of interest. This study firstly explored the inter-factor correlations of the 10 personality aspects of the Work Personality Index (WPI) from an archival dataset of 4759 South African employees. An oblique lower-order model was specified to investigate the inter-factor correlations between personality aspects. Secondly, a dominance analysis was performed using a sequentially collected cross-sectional sample of 197 South African employees, to determine the relative weight that each of the 10 aspects carries when predicting five narrower dimensions of performance. The 10 aspects exhibited unique patterns in predicting narrower performance dimensions. Scientists and practitioners might, therefore, benefit from modelling relationships between personality aspects and narrower performance areas. In accordance, more nuanced selection decisions or development recommendations can be made that are specific to the work behaviours of interest. Contribution: The present study is the first to explore the criterion validity of the 10 personality aspects against five performance areas in the South African context. The study underscores the importance of a more nuanced understanding of the work-related implications of narrower personality characteristics, which have practical implications for both selection decisions and developmental recommendations within organisational settings.

Abstract: Background: Motivation is critical for supporting persistence and achievement in science, technology, engineering, and mathematics (STEM) disciplines. In this study, we focus on the assessment of mathematics motivation among secondary school students. We provide validity and reliability evidence for the Mathematics Motivation Questionnaire (MMQ)—adapted from the Science Motivation Questionnaire designed for college students—using data from 2551 secondary students from seven states across the United States. Results: Exploratory and confirmatory factor analyses confirmed five latent factors of the MMQ indicated by 19 items: intrinsic value, self-regulation, self-efficacy, utility value, and test anxiety. The nonlinear SEM reliability coefficients of the five constructs ranged from 0.76 to 0.91. To assess criterion validity, analyses using a subset of the data that included students’ mathematics standardized scores (n = 536) indicated that intrinsic value, self-regulation, and self-efficacy were significantly positively correlated with mathematics achievement, whereas test anxiety was significantly negatively correlated with mathematics achievement. Conclusions: The MMQ provides a reliable, valid, and feasible measure of the specific factors underlying mathematics motivation among secondary students.

Purpose: The fatigue resistance of the finger flexors is known to be a key determinant of climbing performance. This study set out to establish the association between the single all-out assessment of finger flexor critical force (ff-CF) and the impulse above CF (W') on climbing performance (self-reported sport and boulder climbing ability). Methods: A total of 129 subjects completed an assessment of dominant arm ff-CF, comprised of a series of rhythmic isometric maximum voluntary contractions (CF defined as mean end-test force [in kilograms]; W' impulse above CF [in kilogram second]). Results: The ff-CF protocol resulted in the same force decay to a plateau seen in previous isometric critical torque and critical force tests. Linear regression analysis, adjusting for sex, revealed that CF percentage of body mass explained 61% of sport and 26% of bouldering performance and W' per kilogram body mass explained 7% sport and 34% bouldering performance. A combined model of CF as a percentage of body mass and W' per kilogram body mass, after adjustment for sex differences, was able to explain 66% of sport climbing and 44% of bouldering performance. Conclusions: The results illustrate the relevance of the CF threshold in describing the fatigue resistance of the finger flexors of rock climbers. Given ff-CF ability to describe a considerable proportion of variance in sport climbing and bouldering ability, the authors expect it to become a common test used by coaches for understanding exercise tolerance and for determining optimal training prescription.

Abstract Objective To assess the criterion validity of a dietary screener questionnaire adapted for Asian Americans (ADSQ) compared to Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA-24) food diary data amongst Chinese American Adults (CHAs). The ADSQ incorporated example ethnic foods from six Asian American groups. Lessons learned with respect to translating the ADSQ from English into Simplified Chinese were also documented. Design Agreement between a two-day food diary (one weekend day and one weekday) and the ADSQ was assessed for vegetable, fruit, dairy, added sugar, fiber, calcium, and whole grain intake using paired t-tests to compare means and Spearman correlations to assess agreement between intake of food components. Setting Data were collected online and via phone interviews. Participants Thirty-three CHAs aged 19–62 years (63.6% female). Results Mean differences were small for fruit, dairy, fiber, calcium, and whole grain intake, but were significantly different for vegetables and added sugar intake. Spearman correlations were 0.05) for all components. Both the ASA-24 and the ADSQ identified the same categories where CHAs intake is misaligned with dietary recommendations: whole grains, total fruit, and dairy. Difficulties were encountered in translating 13 out of 26 questions. Conclusions The ADSQ may be a useful tool to identify intervention targets for improving dietary quality, but caution is warranted when interpreting vegetable and added sugar estimates. Differences in the English and Chinese languages underscore the need to take into account both literal translations and semantics in translating the ADSQ into other languages.

Abstract Background The objective of this study was to establish the criterion-related validity of the session-rating of perceived exertion (s-RPE) method in adolescent athletes. Methods According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines, a meta-analysis (PROSPERO ID: CRD42022373126) was performed using Stata 15.1 software. Eight databases using the following terms: (‘s-RPE’ OR ‘Rating Perceived Exertion session’ OR ‘RPE session’ OR ‘RPE’ OR ‘Rate of Perceived Exertion’ OR ‘Rated of Perceived Exertion’) AND (‘Adolescen*’ OR ‘Youth*’ OR ‘Teen*’) AND (‘validity’ OR ‘correlation’ OR ‘concurrent validity’) were searched up to 2022. Articles meeting the inclusion criteria were screened and adopted the “Methodological Index for Non-Randomized Studies (MINORS)” to evaluate the risk of bias. Results An initial 1798 studies using the s-RPE method were identified and finally, a total of 16 studies were included for further analysis. The relationship between assessment instruments CR-10 or CR-100 modified methods of s-RPE and the heart rate measures of these selected studies were calculated using correlation coefficient (r values) and Fisher’s z-score. A strong to very strong correlation between s-RPE and HR was observed (overall: r = 0.74; CR-10: r = 0.69; CR-100: r = 0.80). CR-100 scale (Fisher’s z = 1.09) was shown to have a higher criterion validity than that of the CR-10 scale (Fisher’s z = 0.85). Conclusion Preliminary findings showed that s-RPE using either CR-10 or CR-100 scales can be used "stand-alone" for monitoring internal training load for children and adolescent athletes. Future studies should focus on whether CR-100 could better perform than CR-10 for junior and children athletes in different age groups and sports as well as the causes leading to potential scoring biases.

Abstract Objective Hospitals are frequently associated with poor working conditions that can lead to work stress and increase the risk for reduced employee well-being. Managers can shape and improve working conditions and thereby, the health of their teams. Thus, as a prerequisite, managers need to be aware of their employees’ stress levels. This study had two objectives: At first, it aimed to test the criterion validity of the Effort-Reward Imbalance (ERI) questionnaire measuring psychosocial workload in hospital employees. Secondly, mean scales of the ERI questionnaire filled in by employees were compared with mean scales of an adapted ERI questionnaire, in which managers assessed working conditions of their employees. Methods Managers (n = 141) from three hospitals located in Germany assessed working conditions of their employees with an adapted external, other-oriented questionnaire. Employees (n = 197) of the mentioned hospitals completed the short version of the ERI questionnaire to assess their working conditions. Confirmatory factor analyses (CFA) were applied to test factorial validity, using the ERI scales for the two study groups. Criterion validity was assessed with multiple linear regression analysis of associations between ERI scales and well-being among employees. Results The questionnaires demonstrated acceptable psychometric properties in terms of internal consistency of scales, although some indices of model fit resulting from CFA were of borderline significance. Concerning the first objective, effort, reward, and the ratio of effort-reward imbalance were significantly associated with well-being of employees. With regard to the second objective, first tentative findings showed that managers’ ratings of their employees’ effort at work was quite accurate, whereas their reward was overestimated. Conclusions With its documented criterion validity the ERI questionnaire can be used as a screening tool of workload among hospital employees. Moreover, in the context of work-related health promotion, managers’ perceptions of their employees’ workload deserve increased attention as first findings point to some discrepancies between their perceptions and those provided by employees.

The awareness of the importance of physical literacy (PL) is globally increasing; however, knowledge of the applicability of PL measurement tools in southeastern Europe is limited. The aim of this study was to evaluate the reliability and validity of translated versions of the CAPL-2 and PLAYself questionnaires in 9- to 11-year-old elementary school children from Croatia, Bosnia and Herzegovina, and Montenegro. The participants were 303 children (141 girls; all 9 to 11 years of age) from Croatia (n = 71), Bosnia and Herzegovina (n = 162), and Montenegro (n = 70), enrolled in regular elementary school. The participants were tested throughout a test–retest procedure using two PL evaluation tools, i.e., the Canadian Assessment of Physical Literacy (shorter version, CAPL-2) and the Physical Literacy Assessment of Youth (PLAYself) questionnaires. With an intraclass correlation (ICC) of 0.70–0.80 for specific questionnaire subscales and 0.84 for the total score, PLAYself was found to be reliable. With Kappa values of 0.11–0.23 and a percentage of absolute agreement of less than 62%, CAPL-2 appeared to be less reliable. Factors related to sport participation were significantly positively associated with the PLAYself score, indicating its proper validity. In conclusion, we suggest the usage of the PLAYself questionnaire in further studies examining PL in children of a similar age in the region.

Wireless wearable insoles are interesting tools to collect gait parameters during daily life activities. However, studies have to be performed specifically for each type of insoles on a big data set to validate the measurement in ecological situations. This study aims to assess the criterion validity and test-retest reliability of gait parameters from wearable insoles compared to motion capture system. Gait of 30 healthy participants was recorded using DSPro® insoles and a motion capture system during overground and treadmill walking at three different speeds. Criterion validity and test-retest reliability of spatio-temporal parameters were estimated with an intraclass correlation coefficient (ICC). For both systems, reliability was found higher than 0.70 for all variables (p < 0.001) except for minimum toe clearance (ICC < 0.50) with motion capture system during overground walking. Regardless of speed and condition of walking, Speed, Cadence, Stride Length, Stride Time and Stance Time variables were validated (ICC > 0.90; p < 0.001). During walking on treadmill, loading time was not validated during slow speed (ICC < 0.70). This study highlights good criterion validity and test-retest reliability of spatiotemporal gait parameters measurement using wearable insoles and opens a new possibility to improve care management of patients using clinical gait analysis in daily life activities.

Emotional dysregulation is related to a wide variety of psychological problems; therefore, it is important to have a quality instrument for an efficient assessment. The purpose of this study was to investigate the psychometric properties of the Difficulties in Emotional Regulation Scale in its brief version (DERSR-B) in a Mexican adult population. We worked with a non-probabilistic sample (N=209 Mean=31.16 and SD=8.5) with an age range of 15-50 years. Construct validity, criterion validity, internal consistency and invariance factor analysis were obtained. A 3-factor structure with 14 items was confirmed, with acceptable psychometric parameters (goodnessof-fit indices, Cronbach’s alpha and Omega values, and Pearson’s coefficient). The results are discussed with the findings reported in other populations. The achievements and limitations of the study are addressed. [ABSTRACT FROM AUTHOR]

Background: Balance, i.e., the ability not to fall, is often poor in neurological patients and this impairment increases their risk of falling. The Mini-Balance Evaluation System Test (Mini-BESTest), a rating scale, the Timed Up and Go (TUG) test, and gait measures are commonly used to quantify balance. This study assesses the criterion validity of these measures as balance measures. Methods: The probability of being a faller within nine months was used as the balance criterion. The Mini-BESTest, TUG (instrumented with inertial sensors), and walking test were administered before and after inpatient rehabilitation. Multiple and LASSO logistic regressions were used for the analysis. The diagnostic accuracy of the model was assessed with the area under the curve (AUC) of the receiver operating characteristic curve. Mobility measure validity was compared with the Akaike Information Criterion (AIC). Results: Two hundred and fourteen neurological patients (stroke, peripheral neuropathy, or parkinsonism) were recruited. In total, 82 patients fell at least once in the nine-month follow-up. The Mini-BESTest (AUC = 0.69; 95%CI: 0.62--0.76), the duration of the TUG turning phase (AUC = 0.69; 0.62-0.76), and other TUG measures were significant faller predictors in regression models. However, only the turning duration (AIC = 274.0) and Mini-BESTest (AIC = 276.1) substantially improved the prediction of a baseline model, which only included fall risk factors from the medical history (AIC = 281.7). The LASSO procedure selected gender, disease chronicity, urinary incontinence, the Mini-BESTest, and turning duration as optimal faller predictors. Conclusion: The TUG turning duration and the Mini-BESTest predict the chance of being a faller. Their criterion validity as balance measures in neurological patients is substantial.

Abstract Background The Externalizing Spectrum Inventory-Brief Form (ESI-BF) [1] is a 160-item self-report instrument designed for the assessment of externalizing psychopathology, yet few studies to date have evaluated its psychometric properties, structural fit, and criterion validity in forensic psychiatric settings. Methods Here, we investigated these aspects in a sample of forensic psychiatric inpatients (n = 77) from a maximum-security forensic psychiatric hospital in Sweden. We firstly investigated the reliability. Secondly, using confirmatory factor analysis, the structure of the ESI-BF. And thirdly, using a Bayesian approach, assessed how the three ESI-BF subfactors relate to criterion measures of antisocial behaviors, substance use, and lifetime externalizing spectrum diagnoses. Results The ESI-BF demonstrated good to adequate reliability and internal consistency, with all but four facet scales exhibiting α and ω values ≥ 0.80. Average inter-item correlations for the facet scales ranged from 0.31 to 0.74. However, all structural models exhibited poor to mediocre fit, with model fit values for the CFI being 0.66, 0.79 and 0.87 and RMSEA values of 0.14, 0.12 and 0.09. for the unidimensional correlated factors and bifactor model, respectively. Regarding criterion validity, all subscales of the item-based ESI-BF three-factor model exhibited robust correlations with the Life History of Aggression total, aggression and antisocial/consequences subscales, with correlations ranging from 0.29 to 0.55. All ESI-BF subfactors demonstrated robust associations, yet with different externalizing outcomes, lending tentative support to its criterion validity. Conclusion Despite remaining ambiguities regarding its structural fit, the ESI-BF may be promising for assessing externalizing psychopathology in forensic psychiatric populations. However, further investigation of the ESI-BF is needed before any firm conclusions can be drawn about its appropriateness in forensic psychiatric settings.

Background: The objective of this study was to establish the criterion-related validity of the session-rating of perceived exertion (s-RPE) method in adolescent athletes. Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines, a meta-analysis (PROSPERO ID: CRD42022373126) was performed using Stata 15.1 software. Eight databases using the following terms: ('s-RPE' OR 'Rating Perceived Exertion session' OR 'RPE session' OR 'RPE' OR 'Rate of Perceived Exertion' OR 'Rated of Perceived Exertion') AND ('Adolescen*' OR 'Youth*' OR 'Teen*') AND ('validity' OR 'correlation' OR 'concurrent validity') were searched up to 2022. Articles meeting the inclusion criteria were screened and adopted the "Methodological Index for Non-Randomized Studies (MINORS)" to evaluate the risk of bias. Results: An initial 1798 studies using the s-RPE method were identified and finally, a total of 16 studies were included for further analysis. The relationship between assessment instruments CR-10 or CR-100 modified methods of s-RPE and the heart rate measures of these selected studies were calculated using correlation coefficient (r values) and Fisher's z-score. A strong to very strong correlation between s-RPE and HR was observed (overall: r = 0.74; CR-10: r = 0.69; CR-100: r = 0.80). CR-100 scale (Fisher's z = 1.09) was shown to have a higher criterion validity than that of the CR-10 scale (Fisher's z = 0.85). Conclusion: Preliminary findings showed that s-RPE using either CR-10 or CR-100 scales can be used "stand-alone" for monitoring internal training load for children and adolescent athletes. Future studies should focus on whether CR-100 could better perform than CR-10 for junior and children athletes in different age groups and sports as well as the causes leading to potential scoring biases.

Objective: To assess the criterion validity of a dietary screener questionnaire adapted for Asian Americans (ADSQ) compared to Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA-24) food diary data amongst Chinese American Adults (CHAs). The ADSQ incorporated example ethnic foods from six Asian American groups. Lessons learned with respect to translating the ADSQ from English into Simplified Chinese were also documented. Design: Agreement between a two-day food diary (one weekend day and one weekday) and the ADSQ was assessed for vegetable, fruit, dairy, added sugar, fiber, calcium, and whole grain intake using paired t-tests to compare means and Spearman correlations to assess agreement between intake of food components. Setting: Data were collected online and via phone interviews. Participants: Thirty-three CHAs aged 19–62 years (63.6% female). Results: Mean differences were small for fruit, dairy, fiber, calcium, and whole grain intake, but were significantly different for vegetables and added sugar intake. Spearman correlations were < 0.5 and non-significant (p > 0.05) for all components. Both the ASA-24 and the ADSQ identified the same categories where CHAs intake is misaligned with dietary recommendations: whole grains, total fruit, and dairy. Difficulties were encountered in translating 13 out of 26 questions. Conclusions: The ADSQ may be a useful tool to identify intervention targets for improving dietary quality, but caution is warranted when interpreting vegetable and added sugar estimates. Differences in the English and Chinese languages underscore the need to take into account both literal translations and semantics in translating the ADSQ into other languages. [ABSTRACT FROM AUTHOR]

Background: This study aimed to evaluate the feasibility and validity of the Global Leadership Initiative on Malnutrition (GLIM) criteria in the intensive care unit (ICU). Methods: This was a cohort study involving critically ill patients. Diagnoses of malnutrition by the Subjective Global Assessment (SGA) and GLIM criteria within 24 h after ICU admission were prospectively performed. Patients were followed up until hospital discharge to assess the hospital/ICU length of stay (LOS), mechanical ventilation duration, ICU readmission, and hospital/ICU mortality. Three months after discharge, the patients were contacted to record outcomes (readmission and death). Agreement and accuracy tests and regression analyses were performed. Results: GLIM criteria could be applied to 377 (83.7%) of 450 patients (64 [54–71] years old, 52.2% men). Malnutrition prevalence was 47.8% (n = 180) by SGA and 65.5% (n = 247) by GLIM criteria, presenting an area under the curve equal to 0.835 (95% confidence interval [CI], 0.790–0.880), sensitivity of 96.6%, and specificity of 70.3%. Malnutrition by GLIM criteria increased the odds of prolonged ICU LOS by 1.75 times (95% CI, 1.08–2.82) and ICU readmission by 2.66 times (95% CI, 1.15–6.14). Malnutrition by SGA also increased the odds of ICU readmission and the risk of ICU and hospital death more than twice. Conclusion: The GLIM criteria were highly feasible and presented high sensitivity, moderate specificity, and substantial agreement with the SGA in critically ill patients. It was an independent predictor of prolonged ICU LOS and ICU readmission, but it was not associated with death such as malnutrition diagnosed by SGA. [ABSTRACT FROM AUTHOR]

The structure and measurement of occupational fraud rationalization as one of the motivations for fraudulent behavior has been a major obstacle in theoretical research and practical problems. In order to answer the fundamental question, “What does cognitive rationalization of occupational fraud involve?,” this paper explored the structure and scale development of the internal psychological factors of occupational fraud rationalization. Several research methods were used for this purpose, such as data collection, research interviews, review & verification, project purification, structural verification, and reliability & validity test. The results showed that, based on the internal structure, occupational fraud rationalization presented second-order three-dimensional and first-order eight-dimensional factors. Further, a formal scale containing 27 items related to the structure of the metric was constructed to measure the occupational fraud rationalization. In terms of variable correlations, this paper empirically tested the criterion validity of occupational fraud rationalization from the perspective of personality traits. The result revealed a significant positive (negative) correlation between Machiavellian traits (empathy traits) and occupational fraud rationalization, respectively. In conclusion, this paper provides an attempt to address the cognitive and measurement challenges of occupational fraud rationalization, expanding the application and development of moral disengagement theory in the field of occupational fraud and laying some groundwork for subsequent research and development.

It was aimed to develop a valid and reliable scale to determine the mathematical problem solving anxiety of 4th grade primary school students. Relational survey model was used in the study. The sample of the study consisted of 206 primary 4th students studying in2 public schools of Afyonkarahisar centre. The sample selected by cluster sampling. It was decided that the scale should consist of six factors according to literature review. These are arising from understanding based anxiety, planning and execution of the plan based anxiety, arising from controlling the solution based anxiety, arising from self-efficiency based anxiety, arising from person based anxiety, and arising from the structure of the problem based anxiety. The content validity of Primary Problem Solving Anxiety Scale (PPSAS) was determined by the Lawshe coefficient. Confirmatory factor analysis (CFA) was performed to test the 6-factor 43-item structure for construct validity analysis. Finding show that second-order CFA, the arising from person based anxiety was extracted from the scale due to its low fit with the general anxiety structure. The theoretical structure that emerged as a result of CFA was found to be highly fit with its 5-factor 27-item form. The Croncbach α reliability coefficient for the whole PPSAS was found to be .91. For the sub-factors, .77 for anxiety arising from the understanding process, .79 for anxiety arising from the solution process, .78 for anxiety arising from the control process, .82 for anxiety arising from self-efficiency and .80 for anxiety arising from the structure of the problem. For criterion validity, the relationship between PPSAS and the problem solving test by Ulu (2017) was investigated on 337 students. A moderate negative correlation were observed between both the whole scale and its sub-dimensions with the problem solving test. As a result, PPSAS was found to be valid and reliable with its 5-factor 27-item structure. [ABSTRACT FROM AUTHOR]

Ego resiliency has been considered to be a vital element for psychological health. The Revised Ego Resiliency Scale (ER89-R) is an efficient instrument of ego-resiliency with promising psychometrics. However, the psychometric properties of the scale in Chinese college students are still unclear. This study was to test the psychometric properties of the ER89-R in a sample of 678 university students in Mainland China (mean age = 20.16, SD =1.69, 68.30% female). Confirmatory factor analysis supported a first-order two-factor model of the Chinese version of the ER89-R and evidence of strong invariance across gender. Moreover, the internal consistency values of the Chinese version of the ER89-R were from marginal to acceptable, the stability coefficients over time were moderate. Finally, the criterion validity of the Chinese version of the ER89-R was supported by the expected relations with resilience, mental health, self-efficacy, and perceived stress. These findings suggest that the Chinese version of the ER89-R holds promise as an instrument for evaluating ego-resiliency among Chinese college students. [ABSTRACT FROM AUTHOR]

Objective: Hospitals are frequently associated with poor working conditions that can lead to work stress and increase the risk for reduced employee well-being. Managers can shape and improve working conditions and thereby, the health of their teams. Thus, as a prerequisite, managers need to be aware of their employees' stress levels. This study had two objectives: At first, it aimed to test the criterion validity of the Effort-Reward Imbalance (ERI) questionnaire measuring psychosocial workload in hospital employees. Secondly, mean scales of the ERI questionnaire filled in by employees were compared with mean scales of an adapted ERI questionnaire, in which managers assessed working conditions of their employees. Methods: Managers (n = 141) from three hospitals located in Germany assessed working conditions of their employees with an adapted external, other-oriented questionnaire. Employees (n = 197) of the mentioned hospitals completed the short version of the ERI questionnaire to assess their working conditions. Confirmatory factor analyses (CFA) were applied to test factorial validity, using the ERI scales for the two study groups. Criterion validity was assessed with multiple linear regression analysis of associations between ERI scales and well-being among employees. Results: The questionnaires demonstrated acceptable psychometric properties in terms of internal consistency of scales, although some indices of model fit resulting from CFA were of borderline significance. Concerning the first objective, effort, reward, and the ratio of effort-reward imbalance were significantly associated with well-being of employees. With regard to the second objective, first tentative findings showed that managers' ratings of their employees' effort at work was quite accurate, whereas their reward was overestimated. Conclusions: With its documented criterion validity the ERI questionnaire can be used as a screening tool of workload among hospital employees. Moreover, in the context of work-related health promotion, managers' perceptions of their employees' workload deserve increased attention as first findings point to some discrepancies between their perceptions and those provided by employees.

Aim: In our previous study, we proposed that the total score of the 12 frailty‐related items in the health assessment questionnaire for the national screening program for older adults could be used as an indicator of frailty. We aim to examine the criterion validity of the 12 frailty‐related items for frailty. Methods: The data used in this study were from older Japanese individuals aged 78–81 years (n = 461) who participated in the in‐venue (2019) and mailed questionnaire (2020) surveys of the Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians study. A receiver operator characteristic (ROC) curve analysis was used to evaluate the criterion validity of the 12 frailty‐related items for frailty defined based on the Japanese version of the Cardiovascular Health Study criteria. A multivariable logistic regression model was used to examine the independent association of the 12 frailty‐related items with frailty. Results: The area under the ROC curve of the scores of the 12 frailty‐related items for frailty was 0.79 (95% confidence interval [CI] = 0.73–0.85, P < 0.001). The cut‐off value for frailty was 3 and 4 points, and the sensitivity and specificity were 55.9% and 85.8%, respectively. The multivariable logistic regression model showed that four or more scores of the 12 frailty‐related items were significantly associated with frailty (adjusted odds ratio = 7.75, 95% CI = 4.10–14.65, P < 0.001). Conclusions: The results of this study suggest that the 12 frailty‐related items in the health assessment questionnaire for older adults may be useful for assessing frailty in community‐dwelling older adults in a simplified manner.

It discusses the differences between concurrent and predictive validity, their respective uses, and the challenges and pitfalls associated with criterion of validity.

Abstract Introduction Uveitis is the inflammation of the middle layer of the eye, the uvea, and is a major cause of blindness. None of the instruments used in clinical practice are, in themselves, sufficient to evaluate the course of uveitis. Therefore, it is necessary to develop instruments enabling standardized measurement of inflammatory activity. We developed a composite disease activity index for patients with uveitis known as UVEDAI, which considers the overall activity of the eye. The objective of this study was to validate the composite index of ocular inflammation, UVEDAI. Methods A multicenter cross-sectional study involving eight Spanish tertiary hospitals. Sixty-two patients aged ≥ 18 years with acute uveitis were recruited. Participants gave informed consent before participating in the study. A full ophthalmological examination was performed by two ophthalmologists to determine inflammatory activity: one used the UVEDAI score and the other used clinical judgment. The ophthalmologists did not share their findings with each other to avoid introducing bias into the analysis. Construct validity was established by means of factor analysis. The criterion validity of the index was determined using an ordinal multivariate regression model, in which the dependent variable was the degree of uveal inflammation (mild, moderate, or high/severe). Cut-off points were determined for the UVEDAI and for the receiver operating characteristic (ROC) curves. Results Sixty-two patients were included. Total variance with the three components accounted for 80.32% of the construct validity. Each of the three components identified one type of eye involvement. The discriminatory capacity of UVEDAI was 0.867 (95% CI 0.778; 0.955 p

Summary: This large cohort study investigated reliability and validity of heel ultrasound to estimate bone mineral density in adults. Reliability calculated between left and right heels was relatively poor and so was criterion validity assessed relative to dual-energy X-ray absorptiometry. Heel ultrasound should be used cautiously when estimating bone mineral density. Introduction: Calcaneal quantitative ultrasound (QUS) may be used as a safe, low cost, and portable means to estimate bone mineral density (BMD) in large cohorts. The purpose of this study was to quantify the reliability and validity of QUS in comparison to dual-energy X-ray absorptiometry (DXA), which is the reference method for BMD measurement and diagnoses of osteopenia and osteoporosis. Methods: Bone outcomes measured on the large UK Biobank cohort were used. The reliability of QUS estimated BMD was quantified by comparing values obtained from the left and right heel measured in the same session. Criterion validity was assessed through agreement between QUS and DXA, quantifying correlations, and sensitivity and specificity of osteopenia and osteoporosis diagnoses. Results: Reliability calculations were made using data from over 216,000 participants demonstrating similar QUS BMD values between left and right heels in the absolute scale (Sd of difference for men: 0.12 and 0.07 g·cm−2). However, when expressed in relative scales, including concordance of quartiles, reliability was poor. Agreement between QUS and DXA was quantified using data from 5042 participants. Low to modest correlations (r = 0.29 to 0.44) were obtained between multiple QUS variables and DXA BMD, with sensitivity identified as very poor (0.05 to 0.23) for osteoporosis, and poor (0.37 to 0.62) for osteopenia diagnoses. Conclusions: The findings of this large comparative analysis identify that whilst calcaneal QUS has the potential to produce reliable absolute BMD measurements and demonstrate modest associations with DXA BMD measures, use of that information to make relative statements about participants in the context of the larger population or to appropriately diagnose osteopenia or osteoporosis may be severely limited.

Muscle tissue is prone to changes in composition and architecture following stroke. Changes in muscle tissue of the extremities are thought to increase resistance to muscle elongation or joint torque under passive conditions. These effects likely compound neuromuscular impairments, exacerbating movement function. Unfortunately, conventional rehabilitation is devoid of precise measures and relies on subjective assessments of passive joint torques. Shear wave ultrasound elastography, a tool to measure muscle mechanical properties, may be readily available for use in the rehabilitation setting as a precise measure, albeit at the muscle‐tissue level. To support this postulation, we evaluated the criterion validity of shear wave ultrasound elastography of the biceps brachii; we investigated its relationship with a laboratory‐based criterion measure for quantifying elbow joint torque in individuals with moderate to severe chronic stroke. Additionally, we evaluated construct validity, with the specific sub‐type of hypothesis testing of known groups, by testing the difference between arms. Measurements were performed under passive conditions at seven positions spanning the arc of elbow joint flexion‐extension in both arms of nine individuals with hemiparetic stroke. Surface electromyography was utilized for threshold‐based confirmation of muscle quiescence. A moderate relationship between the shear wave velocity and elbow joint torque was identified, and both metrics were greater in the paretic arm. Data supports the progression toward a clinical application of shear wave ultrasound elastography in evaluating altered muscle mechanical properties in stroke, while acknowledging that undetectable muscle activation or hypertonicity may contribute to the measurement. Shear wave ultrasound elastography may augment the conventional method of manually testing joint mobility by providing a high‐resolution precise value. Tissue‐level measurement may also assist in identifying new therapeutic targets for patient‐specific impairment‐based interventions. [ABSTRACT FROM AUTHOR]

Rating of perceived exertion (RPE) is often used by coaches and athletes to indicate exercise intensity, which facilitates training load monitoring and prescription. Although RPE is typically measured using the Borg’s category-ratio 10-point scale (CR10), digital sports platforms have recently started to incorporate facial RPE scales, which potentially have a better user experience. The aim of this study was to evaluate the validity and reliability of a 5-point facial RPE scale (FCR5) and a 10-point facial RPE scale (FCR10), using the CR10 as a golden standard and to assess their use for training load monitoring. Forty-nine subjects were grouped into 17 untrained (UT), 19 recreationally trained (RT), and 13 trained (T) individuals Subjects completed 9 randomly ordered home-based workout sessions (3 intensities × 3 RPE scales) on the Fitchannel.com platform. Heart rate was monitored throughout the workouts. Subjects performed 3 additional workouts to assess reliability. Validity and reliability of both facial RPE scales were low in UT subjects (intraclass correlation [ICC] ≤ 0.44, p ≤ 0.06 and ICC ≤ 0.43, p ≥ 0.09). In RT and T subjects, validity was moderate for FCR5 (ICC ≥ 0.72, p < 0.001) and good for FCR10 (ICC ≥ 0.80, p < 0.001). Reliability for these groups was rather poor for FCR5 (ICC = 0.51, p = 0.006) and moderate for FCR10 (ICC = 0.74, p < 0.001), but it was excellent for CR10 (ICC = 0.92, p < 0.001). In RT and T subjects, session RPE scores were also strongly related to Edward's training impulse scores (r ≥ 0.70, p < 0.001). User experience was best supported by the FCR10 scale. In conclusion, researchers, coaches, strength and conditioning professionals, and digital sports platforms are encouraged to incorporate the valid and reliable FCR10 and not FCR5 to assess perceived exertion and internal training load of recreationally trained and trained individuals.

Conclusions: The variables included in UVEDAI enable ocular inflammatory activity to be described with a high degree of accuracy. The index may be used to evaluate and classify this activity with considerable discriminatory power. [ABSTRACT FROM AUTHOR]

The present study assessed LENA's suitability as a tool for monitoring future language interventions by evaluating its reliability, construct validity, and criterion validity in infants learning Hebrew and Arabic, across low and high levels of maternal education. Participants were 32 infants aged 3 to 11 months (16 in each language) and their mothers, whose socioeconomic status (SES) was determined based on their years of education (H-high or L-low ME-maternal education). The results showed (1) good reliability for the LENA's automatic count on adult word count (AWC), conversational turns (CTC), and infant vocalizations (CVC), based on the positive associations and fair to excellent agreement between the manual and automatic counts; (2) good construct validity based on significantly higher counts for HME vs. LME and positive associations between LENA's automatic vocal assessment (AVA) and developmental questionnaire (DA) and age; and (3) good concurrent criterion validity based on the positive associations between the LENA counts for CTC, CVC, AVA, and DA and the scores on the preverbal parent questionnaire (PRISE). The present study supports the use of LENA in early intervention programs for infants whose families speak Hebrew or Arabic. The LENA could be used to monitor the efficacy of these programs as well as to provide feedback to parents on the amount of language experience their infants are getting and their progress in vocal production. The results also indicate a potential utility of LENA in assessing linguistic environments and interactions in Hebrew- and Arabic-speaking infants with developmental disorders, such as hearing impairment and cerebral palsy.

Background: The Externalizing Spectrum Inventory-Brief Form (ESI-BF) [1] is a 160-item self-report instrument designed for the assessment of externalizing psychopathology, yet few studies to date have evaluated its psychometric properties, structural fit, and criterion validity in forensic psychiatric settings. Methods: Here, we investigated these aspects in a sample of forensic psychiatric inpatients (n = 77) from a maximum-security forensic psychiatric hospital in Sweden. We firstly investigated the reliability. Secondly, using confirmatory factor analysis, the structure of the ESI-BF. And thirdly, using a Bayesian approach, assessed how the three ESI-BF subfactors relate to criterion measures of antisocial behaviors, substance use, and lifetime externalizing spectrum diagnoses. Results: The ESI-BF demonstrated good to adequate reliability and internal consistency, with all but four facet scales exhibiting α and ω values ≥ 0.80. Average inter-item correlations for the facet scales ranged from 0.31 to 0.74. However, all structural models exhibited poor to mediocre fit, with model fit values for the CFI being 0.66, 0.79 and 0.87 and RMSEA values of 0.14, 0.12 and 0.09. for the unidimensional correlated factors and bifactor model, respectively. Regarding criterion validity, all subscales of the item-based ESI-BF three-factor model exhibited robust correlations with the Life History of Aggression total, aggression and antisocial/consequences subscales, with correlations ranging from 0.29 to 0.55. All ESI-BF subfactors demonstrated robust associations, yet with different externalizing outcomes, lending tentative support to its criterion validity. Conclusion: Despite remaining ambiguities regarding its structural fit, the ESI-BF may be promising for assessing externalizing psychopathology in forensic psychiatric populations. However, further investigation of the ESI-BF is needed before any firm conclusions can be drawn about its appropriateness in forensic psychiatric settings. [ABSTRACT FROM AUTHOR]

The Pandemic Anxiety Inventory (PAI) assesses anxiety symptoms individuals attribute to the presence of a pandemic. We conducted this study of 379 British adults during the COVID-19 pandemic and found that the PAI exhibited excellent reliability and solid criterion validity. Pandemic anxiety was associated with reduced social support, anticipated life changes, financial strain, job loss, economic insecurity, and the hospitalization or death of a close friend or relative. Using correlational and bifactor analyses, we found that the PAI demonstrated solid convergent and discriminant validity. The findings suggest that the PAI can be used in research and clinical practice. [ABSTRACT FROM AUTHOR]

Abstract Muscle tissue is prone to changes in composition and architecture following stroke. Changes in muscle tissue of the extremities are thought to increase resistance to muscle elongation or joint torque under passive conditions. These effects likely compound neuromuscular impairments, exacerbating movement function. Unfortunately, conventional rehabilitation is devoid of precise measures and relies on subjective assessments of passive joint torques. Shear wave ultrasound elastography, a tool to measure muscle mechanical properties, may be readily available for use in the rehabilitation setting as a precise measure, albeit at the muscle‐tissue level. To support this postulation, we evaluated the criterion validity of shear wave ultrasound elastography of the biceps brachii; we investigated its relationship with a laboratory‐based criterion measure for quantifying elbow joint torque in individuals with moderate to severe chronic stroke. Additionally, we evaluated construct validity, with the specific sub‐type of hypothesis testing of known groups, by testing the difference between arms. Measurements were performed under passive conditions at seven positions spanning the arc of elbow joint flexion‐extension in both arms of nine individuals with hemiparetic stroke. Surface electromyography was utilized for threshold‐based confirmation of muscle quiescence. A moderate relationship between the shear wave velocity and elbow joint torque was identified, and both metrics were greater in the paretic arm. Data supports the progression toward a clinical application of shear wave ultrasound elastography in evaluating altered muscle mechanical properties in stroke, while acknowledging that undetectable muscle activation or hypertonicity may contribute to the measurement. Shear wave ultrasound elastography may augment the conventional method of manually testing joint mobility by providing a high‐resolution precise value. Tissue‐level measurement may also assist in identifying new therapeutic targets for patient‐specific impairment‐based interventions.

The Roberts Apperception Test for Children (RATC) is a projective method developed by McArthur and Roberts (1982) to assess children and adolescents' behavioural, social and emotional functioning, concerns, conflicts and emotional management strategies through their perceptions of common interpersonal situations of everyday life. The aim of the present study is to contribute to the validation of the RATC in a forensic sample (N = 75) [constituted by a group of juvenile delinquents detained in educational centres (n = 40, 12–17 years old, 1–10 years of schooling) and a group of maltreated adolescents integrated in residential care (n = 35, 11–16 years old, 5–10 years of schooling)], studying its psychometric properties, such as reliability and criterion validity (convergent and discriminant validity), considering the results obtained in other instruments as external validation criteria: Wechsler Intelligence Scale for Children – Third Edition (WISC-III) and Youth Self-Report (YSR). It also aims to search for some indicators based on means and standard deviations to interpret the scores obtained in RATC for these forensic contexts, through the comparisons within forensic groups and the comparisons of the forensic groups with a community sample. The RATC showed minimally acceptable reliability and adequate validity indices, considering that this instrument is a projective method. This limitation is compensated by the clinical value of the data obtained from the projection of individuals' thoughts, concerns, conflicts and problem-solving styles, which are useful to assess their emotional and behavioural characteristics and psychological functioning. The results also show statistically significant differences between the two forensic groups on RATC scales, as well as between them and the community sample, as expected, underlining their different characteristics.
