Matching alternatives of the Prioritizing Positivity scale among university students according to the Andrich rating scale model

Abstract

The current research aims to measure the accuracy of matching alternatives to the Prioritizing Positivity scale among university students according to the Andrich rating scale model. In order to achieve this goal, the researcher chose a sample of (378) male and female students extracted using the Thomson equation and then distributed using the proportional random stratified method. The researchers used statistical procedures specific to the item response theory, as the researchers chose the Andrich rating scale model and used statistical programs (Jomavi & Jmetrik). The model's assumptions were achieved, as the measurement paragraphs' alternatives enjoyed good matching and high psychometric properties for the paragraphs and the measurement tool as a whole. Based on these results, the researchers developed a set of conclusions, recommendations and proposals.
