Dissertation/Thesis Abstract

Single item versus multiple items: An examination of validity and the impact of mood in measuring constructs
by Kuls, Michaela, M.A., California State University, Long Beach, 2012, 69; 1522237
Abstract (Summary)

The study explored the effect of mood moderation and the equivalence between single-item and multiple-item scales. It examined how mood affects validity and stability differently between the scales. Mood was induced in the form of brownies, fresh fruit, and drinks. The study utilized the personality measure positive affectivity and job attitude scales, including turnover intention and job satisfaction, to assess differences. The job satisfaction single-item scale was correlated with positive affectivity and turnover intentions and compared with the job satisfaction multiple-item scale in measures of neutral and positive mood conditions. A total of 180 working students participated. Contrary to predictions, a Fisher's z test showed that mood moderated the multiple-item scales for positive affectivity and job satisfaction more than the single-item scale. The multiple-item scales appeared to be more susceptible to mood moderation, demonstrating more fluctuation and variability than the single-item scale.
