The Effect of the Number of Response Categories of Likert Anxiety Trait Scale on its Psychometric Characteristics

Abstract

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.
