条目反应理论MG-Bilog软件在量表研究中的应用
Application of item response theory MG-Bilog software in the analysis of instrument
摘要
Abstract
BACKGROUND:Item response theory is gradual y used in the scale and questionnaire. However, the principles are profound and complicated, which makes it difficult to popularize. Therefore, the researchers have developed a series of softwares such as Bilog-MG software to deal with two-category data through writing program or clicking on the page. <br> OBJECTIVE:To introduce the Bilog-MG software using an example. <br> METHODS:Four items of physical role in the SF-36 scale were selected, and a total of 532 patients with nasopharyngeal carcinoma were enrol ed for analysis. The main steps of Bilog-MG software included:basic definition and analysis model, definition of item analysis and estimation methods, definition of test score, definition of the data, definition of the correct answer, saving the data, and generating grammar. <br> RESULTS AND CONCLUSION:(1) The steps of Bilog-MG software focused on the definition of the model (the number of test, grouping, items of test), definition of the analysis model (single parameter, double parameters, three parameters model), and definition of data and format. (2) The results of analysis included:item statistics, item parameter estimation values and the reliability coefficient. It also included the fol owing graphics:item characteristic curves, item information curve and overal information curve. (3) In conclusion, the Bilog-MG software is easy to learn, and can accurately estimate the item and ability parameters. We hope Bilog-MG software can be widely used in medical research.关键词
