OROZCO V., Luis C. et al. Dimensional anxiety: An analysis from the classical theory of the Zung self-rating anxiety scale. Rev. Univ. Ind. Santander. Salud [online]. 2011, vol.43, n.2, pp.159-166. ISSN 0121-0807.

Introduction: There is not a published report of the invariance of anxiety Zung test, although is widely used. Objective: To stablish gender invariance of the Zung self-rating anxiety scale using Classical Test Theory. Methods: A non random sample of 336 women and 205 men students from several colombian universities that answered the scale. Confirmatory factor analysis was performed. Dimensional, configurational and metric invariance were investigated. Results: Dimensional and configurational invariance are met because for both genders theres is one dimension, using Bayesian Information Crietria as the model selection strategy, and the loadings are generally high. The metric invariance was obtained after deleting 9 items. Conclusion: Eleven items of The Zung self-rating anxiety scale show dimensional, configurational and metric invariance.

Keywords : The Zung self-rating scale; invariance; factor analysis.
