<p style="text-align: justify;">This study was conducted to corroborate in understanding the teachers’ beliefs about assessment practices. The prior studies related to teachers’ assessment beliefs in mathematics have been done to assess teachers’ beliefs in the general context of mathematics teaching. This study developed an instrument to assess teachers’ assessment beliefs of mathematical thinking. The research aimed to develop and validate a scale of assessment beliefs of mathematical thinking by using the confirmatory factor analysis. The first draft of the scale contained 25 items. The sample of the study consisted of 537 mathematics teachers from public schools in Oman. The instrument was a questionnaire with a 5-point Likert scale. The scale was validated by asking a number of experts in mathematics educational measurement and evaluation. Exploratory and confirmatory factor analysis was applied to test the model of assessment beliefs of mathematical thinking scale using AMOS 25.0. All constructs had acceptable reliability. The model had a good model fit for the assessment beliefs of mathematical thinking scale which obtainable from the fit indices tests. The findings revealed that all fit criteria indices were realized. The results also showed acceptable validity and construct reliability for the scale.</p>

Abstract The objective of this study is to investigate the evidence of construct validity of a phonological awareness instrument. Exploratory factor analysis was carried out on data collected from 510 elementary and middle school students in 2nd and 6th grades attending two different public schools in the city of São Paulo, Brazil; most were males with mean age of 8.4 years. Confirmatory factor analysis was carried out on data collected from 427 students from other four Brazilian states in the same grades; most were females with mean age of 9.3 years. The instrument used was the Roteiro de Avaliação da Consciência Fonológica, a phonological awareness test. The exploratory factor analysis showed a three-factor solution. As for the confirmatory factor analysis, of the two models tested, the one that indicated better model fit indices was composed of three factors. The model found is adequate for the task carried out in this study. However, more studies should be carried out to further refine the instrument.

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.

The aim of this research is confirmatory factor analysis of Aurora-a Battery on Iranian children. Aurora-a Battery is a cognitive assessment according to Robert J. Sternberg’s theory of Successful Intelligence. 400 children 9-12 years old were selected through multi-steps sampling method and were tested with Aurora-a test. These children were from geographically diverse schools in Isfahan city, Iran. The factor analysis of data was performed through Amos software. Fit indices show that data fit with model. Moreover, the correlation between test total score and the analytical, creative and practical intelligences were 0.91, 0.94 and 0.84, respectively. Alpha for Aurora’s total score was equal to 0.92 as well. Aurora-a test can be an appropriate and valid instrument for identification gifted children aged 9-12 according to Sternberg’s theory of successful intelligence. This test allows many children to be identified as gifted which in turn provides the opportunity of further development of their potential.

The presence of dysfunctional cognitions about how individuals see themselves and others is a hallmark of psychopathology. The Brief Core Schemas Scale (BCSS) was developed to evaluate adaptive and dysfunctional beliefs about the self and others. This study describes the first psychometric analysis of the BCSS in the Portuguese population. Participants were recruited from community ( N = 320, Mage=27.31, DP = 12.75). Confirmatory factor analysis (CFA) was used to confirm the BCSS factorial structure. Four-factor model revealed moderate to adequate goodness-of-fit indices (χ2/df = 717.1, (246) p = .01; SRMR = .044; RMSEA = .077; CFI/TLI < .90). Negative views of the self and others correlated positively with early maladaptive schemas, distress, and symptomatology and correlated negatively with psychological well-being. An inversed correlational pattern was found with the positive views of the self and others. Despite the model's moderate adherence to the data, results suggest that the BCSS may be an asset in the assessment of dysfunctional and adaptive cognitions about the self and others. Further analysis is required to deepen the psychometric properties of the BCSS in the Portuguese population.

Context The Disablement in the Physically Active (DPA) scale is a patient-reported outcome instrument recommended for use in clinical practice and research. Analysis of the scale has indicated a need for further psychometric testing. Objective To assess the model fit of the original DPA scale using a larger and more diverse sample and explore the potential for a short-form (SF) version. Design Observational study. Setting Twenty-four clinical settings. Patients or Other Participants Responses were randomly split into 2 samples: sample 1 (n = 690: 353 males, 330 females, and 7 not reported; mean age = 23.1 ± 9.3 years, age range = 11–75 years) and sample 2 (n = 690: 351 males, 337 females, and 2 not reported; mean age = 22.9 ± 9.3 years, age range = 8–74 years). Participants were physically active individuals who were healthy or experiencing acute, subacute, or persistent musculoskeletal injury. Main Outcome Measure(s) Confirmatory factor analysis was conducted to assess the factor structure of the original DPA scale. Exploratory factor, internal consistency, covariance modeling, correlational, and confirmatory factor analyses were conducted to assess potential DPA scale SFs. Results The subdimensions of the disablement construct were highly correlated (≥0.89). The fit indices for the DPA scale approached recommended levels, but the first-order correlational values and second-order path coefficients provided evidence for multicollinearity, suggesting that clear distinctions between the disablement subdimensions cannot be made. An 8-item, 2-dimensional solution and a 10-item, 3-dimensional solution were extracted to produce SF versions. The DPA SF-8 was highly correlated (r = 0.94, P ≤ .001, R2 = 0.88) with the DPA scale, and the fit indices exceeded all of the strictest recommendations. The DPA SF-10 was highly correlated (r = 0.97, P ≤ .001, R2 = 0.94) with the DPA scale, and its fit indices values also exceeded the strictest recommendations. Conclusions The DPA SF-8 and SF-10 are psychometrically sound alternatives to the DPA scale.

A good theory-based tool for measuring ethical sensitivity, which is usable in different contexts, is scarce. In this study, we examined the Ethical Sensitivity Scale Questionnaire (ESSQ) in line with its seven-dimension structure. The scale was presented to a sample of 556 Iranian Kurdish teachers in primary, middle, and high schools. A confirmatory factor analysis was conducted to scrutinize the original factor structure of the ESSQ. The results confirmed that the ESSQ supports a reasonable model fit to study the seven dimensions of ethical sensitivity as it was developed in the original study. However, some modifications were conducted to free high error covariance between four pairs of items in the scale. This modification increased the fit indices and thus resulted in a good model fit. In addition to examining the satiability of the ESSQ, a further analysis showed that the level of ethical sensitivity in the targeted sample was high.

Literatures in the field of psychometrics recommend researchers to employvarious of methods on measuring individual attributes. Ideally,each methods are complementary and measuresthe construct designed to be measured. However, some problems arise when among the methods is unique and unrelated to the construct being measured. The uniqueness of method can lead what is called the method effect. In testing construct validity using confirmatory factor analysis, the emergence of this effect tend to reducing the goodness of fit indices of the model. There are many ways to solve these problem, one of themis controling the method effects and accommodate it to the model. This paper introduces how to accommodate method effecton the confirmatory factor analysis using structural equation modeling. In the application section, author identify the emergence of method effects due to the differences item writing direction (favorable-unfavorable). The analysis showed that method effectemerge from different writing direction.

Abstract Background: The Salzburg Emotional Eating Scale (SEES) and the Emotional Eater Questionnaire (EEQ) are self-reported measures developed to evaluate emotional eating in adults in Western countries. To date, the psychometric properties of the SEES and the EEQ have not been studied among Iranian adults. The aim of the current study is to translate the SEES and the EEQ from English to Persian and examine the psychometric properties of the SEES and EEQ.Method: The sample of this study comprised of 489 Iranian adults who completed the SEES and the EEQ questionnaires online. Results: Findings of face, content, and construct validity tests confirmed that the SEES and the EEQ had acceptable validity and appropriate reliability. The results from confirmatory factor analysis showed acceptable goodness-of-fit indices for two measures. Conclusion: Results of Average Variance Extracted, Construct Reliability, and goodness-of-fit indices showed that the SEES was better for evaluating emotional eating among Iranian adults than the EEQ.
