Developmental Dyspraxia

The purpose of this study was to examine the construct validity of the praxis tests of the Sensory Integration and Praxis Tests (SIPT) and to determine whether the practic component of sensory integration-based developmental dyspraxia is a unitary or a multidimensional disorder. Developmental dyspraxia is an impaired ability to plan and execute skilled or nonhabitual motor tasks; however, its underlying cause, or even whether praxis is a unitary or multidimensional function, is not yet clarified. In this study, the Rasch model of measurement (Linacre, 1989; Wright & Masters, 1982; Wright & Stone, 1979) was used to explore the underlying construct of developmental dyspraxia. The Rasch model was chosen because its use enabled us to (a) confirm goodness-of-fit of individual items within SIPT praxis tests and (b) examine the hierarchical structure of item difficulties. The data included the raw scores of the SIPT praxis tests of 210 subjects from Canada and the United States. The results of the Rasch analyses revealed that each of these five SIPT praxis tests measures a single, unidimensional construct. When the items from the five tests were combined to create a single 117-item test, the items continued to define a single practic function. This indicates that a unitary practic component underlies both bilateral integration and sequencing deficits and somatodyspraxia. Finally, examination of the hierarchy of item difficulties resulted in recommendations for the development of a single screening test for developmental dyspraxia. The implications of these results for clinical practice and future research are discussed.

To test the applicability of item response theory (IRT) to the Korean Nurses' Licensing Examination (KNLE), item analysis was performed after testing the unidimensionality and goodness-of-fit. The results were compared with those based on classical test theory. The results of the 330-item KNLE administered to 12,024 examinees in January 2004 were analyzed. Unidimensionality was tested using DETECT and the goodness-of-fit was tested using WINSTEPS for the Rasch model and Bilog-MG for the two-parameter logistic model. Item analysis and ability estimation were done using WINSTEPS. Using DETECT, Dmax ranged from 0.1 to 0.23 for each subject. The mean square value of the infit and outfit values of all items using WINSTEPS ranged from 0.1 to 1.5, except for one item in pediatric nursing, which scored 1.53. Of the 330 items, 218 (42.7%) were misfit using the two-parameter logistic model of Bilog-MG. The correlation coefficients between the difficulty parameter using the Rasch model and the difficulty index from classical test theory ranged from 0.9039 to 0.9699. The correlation between the ability parameter using the Rasch model and the total score from classical test theory ranged from 0.9776 to 0.9984. Therefore, the results of the KNLE fit unidimensionality and goodness-of-fit for the Rasch model. The KNLE should be a good sample for analysis according to the IRT Rasch model, so further research using IRT is possible.

The condition of Indonesia is currently being faced by the corona virus (COVID-19) pandemic 2019. The importance of solutions related to the existence of the role of teachers or educators to provide references such as social support to students in learning and teaching activities from home, this study conducted to provide research tools or instruments that can be used by educators or researchers by testing the validity of a social support construct (Social Provision Scale) measuring instrument using the Rasch Model. Although much has been done to test the validity of the Social Provision Scale, no one has examined it by involving social support in the context of Education. Likewise, the majority of research on social support uses confirmatory factor analysis, and no one has used the Rasch Model in validating the Social Provision Scale instrument, especially in Indonesia. The data used are secondary data from Putra of 326 people in SMA Negeri 29 South Jakarta using cluster sampling. The results of the application of the Rasch Rating Scale model show that the psychometric characteristics of the Social Provision Scale are very good and precise, as well as the compatibility of the items to the model. Implications and suggestions for future research are also discussed.

The Rasch Model

Background: The BETA nursing measure has been introduced as a tool to routinely measure and monitor the outcomes of patients' activities of daily living in a restorative nursing care context.Objectives: To investigate the BETA's construct validity using the Rasch model with specific reference to the BETA's potential to be used as an interval scale providing metric or interval data.Method: A quantitative analytical design was followed using Rasch analyses whereby BETA raw data was collected from patients (n = 4235) receiving nursing care in 28 South African sub-acute and non-acute nursing facilities. The data was prepared for Rasch analyses and imported into WINSTEP® Software version 3.70.1.1 (2010). Final results were shown by means of figures and graphs.Results: A successful outcome was achieved by dividing the BETA into four subscales. In this process one of the original BETA items was omitted and seven other items required collapsing of their categories before the four subscales achieved a satisfactory fit to the Rasch model.Conclusion: The four BETA subscales achieved “very well” to “excellent” levels of fit to the Rasch model. This finding thus creates an opportunity to convert the BETA's Likert qualities into an interval measure to calculate change in patients' activities of daily living metric allyas a direct result of effective restorative nursing.

The Rasch Model

The aim of the study was to conduct a first validation of three field practice experience scales intended to measure students’ opportunities to learn through observation of other teachers, own practice and feedback on own practice of 12 key teaching activities while in field practice placement as part of teacher education programs. The scales were translated and adapted from the elementary teaching candidate survey from the Development of Ambitious Instruction project. Items were adapted to refer to the teaching subject students were training in, and the response scale was modified. A four-step translation-back-translation strategy was used, and subsequently the Danish and a Norwegian and Icelandic translations were mutually adjusted for meaning to facilitate later cross-Nordic studies. Participants were 345 Danish students in the teacher education program from one university college, who had been in at least one field practice placement. Data were collected using a targeted online survey during one month immediately following field placement. Data was analysed using the Rasch model. Each of the three field experience scales fitted a Rasch model, with no evidence against overall homogeneity of scores for low versus high scoring students, local dependence between items, or DIF in relation to level of field practice, campus, type of teacher education program, gender or age. Reliability of each scale was excellent for most subgroups, while the targeting of the scales to the study sample was not very good, as there were too few teaching activities occurring rarely during field practice (i.e. too few difficult items). For all three scales there were significant differences in mean scores dependent on level of field practice placement. Thus, while the scales should be expanded to get better coverage of students’ opportunities to learn in relation to all the core teaching activities present in that are to be trained in the field practice placement, the very good psychometric properties of the three scales, shows promise for future research.
