A Shortened Stress Measure in Military Nursing Personnel
Abstract
Stress is a psychological construct with important consequences for human health. A substantial number of stress measures are available that vary in length and dimensionality. The purpose of this study was to determine whether one of these measures, the Perceived Stress Questionnaire (PSQ), could be shortened in a psychometrically sound fashion to enhance its usability. The original PSQ has 30 items, and, more recently, a 20-itemversion was proposed. We used existing data from Air Force nursing personnel (n = 250) to shorten the PSQ through a combination of classical test theory and item response theory techniques. The resulting six-item measure, the PSQ6, had scale scores that correlated highly with PSQ30 andPSQ20 scale scores (intraclass correlation coefficient= .92), strong internal consistency (Cronbach's a= .85), and associations with stigma, perceived barriers, and resilience scale scores that were similar in strength to longer versions of the PSQ.
