The current study examined the psychometric properties of a short form of the trait scale of the Spielberger State-Trait Anxiety Inventory. Participants consisted of a convenience sample of students ( n = 322) who completed the five-item version of the trait scale of the State-Trait Anxiety Inventory, the Perceived Stress Scale, the nine-item version of the Beck Hopelessness Scale, the 10-item version of the Center for Epidemiological Studies Depression Scale, and the Post-Traumatic Stress Disorder Checklist. We used classical test theory and item response theory (Rasch and Mokken analyses) to examine the psychometric properties of a previously proposed five-item version of this scale. These approaches confirmed that the five-item measure of anxiety had satisfactory reliability and validity, and also confirmed that the five items comprised a unidimensional scale.
