<p>Hajj Instrument (HAJI) was developed to determine hajj pilgrim’s wellness. This study used Rasch measurement to evaluate the psychometric properties including validity and reliability of the HAJI. The respondents involved in this study were 300 comprised of Malaysian hajj pilgrims. HAJI consists of eight constructs namely physical care, physical activity, healthy eating, knowledge, mental toughness, intrapersonal, interpersonal and relationship with Creator and natures. Validity of each construct and content was determined through dimensionality, item fit and item polarity while the reliability was achieved by administered person and item separation. The results showed that the reliability for both item and person were 0.99 and 0.96 respectively. Besides, there were no items need to be dropped based on PTMEA CORR and INFIT MNSQ results. The study revealed that the items of HAJI fit the Rasch model as well as able to measure hajj pilgrim’s wellness. </p>

Learner Profile

Background: The International Baccalaureate Middle Years Programme (IBMYP) aims to produce a holistic transformation with creative and critically minded students. However, very little attention has been paid to the development of an instrument to measure the IB learner profile with good psychometric properties. Purpose: This study aims to develop an instrument with good psychometric properties, based on the Rasch measurement model and confirmatory factor analysis. Methods: The study consists of two phases of pilot and field studies involving 597 year four students from IBWS MOE. Results: The findings from the Rasch measurement model analysis have shown that 54 items meet the criteria of the item fit, unidimensionality, and reliability index. Meanwhile, confirmatory factor analysis found that 44 items have shown a valid item fit index. Conclusions: The combination of both analyses has shown the strength of 10IBLP-I psychometric properties that cover the aspects of validity and reliability. The findings also provide an implication to the theory, with empirical evidence that the IB learner profile consists of 10 constructs. Besides, the evidenced 10IBLP-I comprises good psychometric properties, which can be used to measure the level of IB learner profile among IBWS MOE students to assess the effectiveness of the implementation of IBMYP in Malaysia.

Special Case

Rasch model is a method that has a long history in its application in the fields of social and behavioral sciences including educational measurement. Under certain circumstances, Rasch models are known as a special case of Item response theory (IRT), while IRT is equivalent to the Item Factor Analysis (IFA) models as a special case of Structural Equation Models (SEM), although there are other ‘tradition’ that consider Rasch measurement models not part of both. In this study, a simulation study was conducted to using simulated data to explain how the interrelationships between the Rasch model as a constraint version of 2-parameter logistic (2-PL) IRT, Rasch model as an item factor analysis were compared with the Rasch measurement model using Mplus, IRTPRO and WINSTEPS program, each of which came from its own 'tradition'. The results of this study indicate that Rasch models and IFA as a special case of SEM are mathematically equal, as well as the Rasch measurement model, but due to different philosophical perspectives people might vary in their understanding about this concept. Given the findings of this study, it is expected that confusion and misunderstanding between the three can be overcome.

This research is part of the standardization of the Students' Coping Strategy Scale (SCSS). This study aims to reveal the content validity, empirical validity, and reliability of the SCSS. The non-test instrument consisting of 42 statements from three dimensions: problem-focused coping, emotion-focused coping, and seeking social support. Content validity analysis was carried out by experts to obtain Gregory's content validity coefficient, while the empirical validity and reliability analysis by empirically testing the instrument on 211 respondents and analyzed using the Rasch model approach. The results show that Gregory's content validity coefficient is 0.714, so it needs improvement on some items that are considered unsuitable. Empirical validity analysis using WINSTEPS software shows that three items do not fit the model. The reliability coefficient of the SCSS is 0.99. Thus, the remaining 39 items are appropriate to be used to measure students' coping strategies.

Unambiguously, nowadays healthy eating patterns have attracted the interest of researchers, society and media. Mainly four key widespread messages “eat less fat”, “eat less sugar”, “eat less salt” and “eat more fibre”, are among those widely perceived as healthy eating behavior. All those messages could support a healthy eating lifestyle, and consequently, avoid several chronic diseases and health problems. This research aimed to examine consumers' attitudes towards healthy eating, their difficulty to adopt a permanent healthy eating style and to assess which items consumers find more or less difficult to follow. The Rasch model was applied to assess the obstacles consumers are facing to adopt and follow healthy eating patterns and to relate them with a range of attitudinal and socio-economic factors faced by individuals. Results highlight significant differences among consumers in adopting healthy eating patterns, depending on the level of several key factors (gender, age and education).

The Rasch measurement principles espoused in the Bond & Fox (2001) volume reviewed elsewhere in this journal are routinely adopted by Australia's major educational measurement projects (e.g., by Australian Council for Educational Research, Educational Testing Centre). Yet those ideas are yet to have their full impact in smaller research projects in educational and developmental psychology. A number of quantitative analytical techniques used in our disciplines are able to help us to draw conclusions like “Betty is better than or more developed than Bob”, but Rasch measurement is uniquely placed to help us conclude that “Betty is this much better than or more developed than Bob.” In educational and psychological statistics, we regularly presume the “interval” nature of our research data, but only the Rasch model sets about to ensure that the units of measurement maintain their unit value across the whole achievement or development scale.

Purpose Psychometric analyses of self-administered questionnaire data tend to focus on items and instruments as a whole. The purpose of this paper is to investigate the functioning of the response scale and its impact on measurement precision. In terms of the response scale direction, existing evidence is mixed and inconclusive. Design/methodology/approach Three experiments are conducted to examine the functioning of response scales of different direction, ranging from agree to disagree versus from disagree to agree. The response scale direction effect is exemplified by two different latent constructs by applying the Rasch model for measurement. Findings The agree-to-disagree format generally performs better than the disagree-to-agree variant with spatial proximity between the statement and the agree-pole of the scale appearing to drive the effect. The difference is essentially related to the unit of measurement. Research limitations/implications A careful investigation of the functioning of the response scale should be part of every psychometric assessment. The framework of Rasch measurement theory offers unique opportunities in this regard. Practical implications Besides content, validity and reliability, academics and practitioners utilising published measurement instruments are advised to consider any evidence on the response scale functioning that is available. Originality/value The study exemplifies the application of the Rasch model to assess measurement precision as a function of the design of the response scale. The methodology raises the awareness for the unit of measurement, which typically remains hidden.

The Rasch Model

The Test of Early Mathematics Ability–Third Edition (TEMA-3) is a commonly used measure of early mathematics knowledge for children aged 3 years to 8 years 11 months. In spite of its wide use, research on the psychometric properties of TEMA-3 remains limited. This study applied the Rasch model to investigate the psychometric properties of TEMA-3 from three aspects: technical qualities, internal structure, and convergent evidence. Data were collected from 971 K1 children in Singapore. Item fit statistics suggested a reasonable model-data fit. The TEMA-3 items were found to demonstrate generally good technical qualities, interpretable internal structure, and reasonable convergent evidence. Implications for test development, test use, and future research are further discussed.

The Rasch Model

Any high-stakes assessment that leads to an important decision requires careful consideration in determining whether a student passes or fails. Despite the implementation of many standard-setting methods in clinical examinations, concerns remain about the reliability of pass/fail decisions in high stakes assessment, especially clinical assessment. This observational study proposes a defensible pass/fail decision based on the number of failed competencies. In the study conducted in Erbil, Iraq, in June 2018, results were obtained for 150 medical students on their final objective structured clinical examination. Cutoff scores and pass/fail decisions were calculated using the modified Angoff, borderline, borderline-regression, and holistic methods. The results were compared with each other and with a new competency method using Cohen’s kappa. Rasch analysis was used to compare the consistency of competency data with Rasch model estimates. The competency method resulted in 40 (26.7%) students failing, compared with 76 (50.6%), 37 (24.6%), 35 (23.3%), and 13 (8%) for the modified Angoff, borderline, borderline regression, and holistic methods, respectively. The competency method demonstrated a sufficient degree of fit to the Rasch model (mean outfit and infit statistics of 0.961 and 0.960, respectively). In conclusion, the competency method was more stringent in determining pass/fail, compared with other standard-setting methods, except for the modified Angoff method. The fit of competency data to the Rasch model provides evidence for the validity and reliability of pass/fail decisions.

This study aims to explore a set of items measuring the lecturers’ teaching practice for developing a true scale of teaching practice. Rasch Model is applied to produce specific measurements on the lecturers’ teaching practice in order to generalize results and inferential studies. The items proved to measure a single dimension of lecturers’ teaching practice. The developed instrument termed LTP covers five dimensions. Construct validity was achieved through the Rasch Model Analysis using the dimensionality, item fit, and item polarity parameters. The reliability of the instrument was achieved by conducting person and item separation analysis, Cronbach alpha, and calculated person and item reliability estimates. The results of Rasch Model Analysis show that the items of LTP fit the model appropriately.
