Anxiety in brief: Assessment of the five-item trait scale of the state-trait anxiety inventory in South Africa. International Journal of Environmental Research and Public Health, 20(9), 5697. https://doi.org/10.3390/ijerph200956971660-4601https://doi.org/10.3390/ijerph20095697http://hdl.handle.net/10566/8959The 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.enPsychologyAnxietySouth AfricaPsychometric propertiesPsychopathologyArticle
