The development of digital technology provides a significant role in the learning process. However, its utilization is very closely related to skills possessed by teacher. These can be identified with literacy instruments. This study aims measure accuracy and feasibility instruments for teachers. type research used descriptive quantitative non-experimental/survey design. sample consisted 96 tea...

BACKGROUND Despite the widespread use of patient-reported Outcomes (PRO) in clinical studies, their design remains a challenge. Justification of study size is hardly provided, especially when a Rasch model is planned for analysing the data in a 2-group comparison study. The classical sample size formula (CLASSIC) for comparing normally distributed endpoints between two groups has shown to be in...

OBJECTIVE To describe item and person parameters obtained with the Rasch model, one of the item response theory models, in the assessment of personality disorders based on Millon's theory. METHOD A total of 350 people participated in the study. Age ranged from 18 to 67 years (mean ± standard deviation = 27.02±10.13), and 71.7% of the participants (n = 251) were female. Of the 350 individuals,...

BACKGROUND Our objective was to evaluate the measurement properties of the Pain Stages of Change Questionnaire (PSOCQ) and its four subscales Precontemplation, Contemplation, Action and Maintenance. METHODS A total of 231 patients, median age 42 years, with chronic musculoskeletal pain responded to the 30 items in PSOCQ. Thresholds for item scores, and unidimensionality and invariance of the ...

BACKGROUND The Educational Needs Assessment Tool (the ENAT) is a 39-item patient questionnaire originally developed in the UK to assess educational needs of patients with rheumatoid arthritis (RA). The objective of this study was to assess the cross-cultural validity of the ENAT in 7 European countries. METHODS The ENAT was translated into Dutch, Finnish, Norwegian, Portuguese, Spanish and Sw...

OBJECTIVE Advances in health measurement have led to the application of Rasch Item Response Theory (IRT) analysis (Rasch analysis) to evaluate instruments measuring health status and quality of life of patients, including the Health Assessment Questionnaire and SF-36. This study investigated the extent to which the Western Ontario MacMaster osteoarthritis questionnaire (WOMAC) satisfies the Ras...

BACKGROUND There is a growing awareness of the need for easily administered, psychometrically sound screening tools to identify individuals with elevated levels of psychological distress. Although support has been found for the psychometric properties of the Depression, Anxiety and Stress Scales (DASS) using classical test theory approaches it has not been subjected to Rasch analysis. The aim o...

The main purpose of this research is to computerize GSP chart and Rasch GSP methods. GSP chart and Rasch GSP are effective and useful methods which used for analyzing and evaluating academic achievement. GSP chart provides information for diagnosing the learning status of students and the quality of questions while Rasch GSP provides information for assessing the quality of classes and test qua...
