الملخص EN

This study aims at identifying the number effect of response scaling categories of anxiety trait scale on its psychometric characteristics The study is applied on a sample of (352) male and female undergraduate students of Yarmouk University who are registered in the first semester 2017/2018 and selected randomly and hierarchically.

Results concerning discriminated coefficients have also highlighted the existence of statistically significant differences at the function level (α=0.05) in discriminated coefficients between the triple scaling and the quatrain scaling in favor of the quatrain, and between the triple scaling and the quinary scaling in favor if the quinary.

The quinary scaling shows high reliability in comparison with the triple scaling and the quatrain scaling
