The Perceived Stress Scale (PSS) is a self-report measure of global stress. The psychometric properties of the PSS have been studied extensively with diverse samples, including counselors, but only limitedly using item response theory and in longitudinal samples. We will discuss findings from a recent longitudinal study (three timepoints over a one-year period) of the psychometric properties of the PSS-4, a four-item version of the PSS, in a sample of 374 counselors.
