RIVERA I, Blanca M; CORRALES R, Andrés E; CACERES R, Óscar  y  PINA L, Julio A. Validation Of The Zung Depression Scale In Persons With HIV. Ter Psicol [online]. 2007, vol.25, n.2, pp.135-140. ISSN 0718-4808.  http://dx.doi.org/10.4067/S0718-48082007000200004.

We describe the psychometric properties of the Zung's depression scale, which was administered to 62 persons with HIV who were being treated in the Ambulatory Center of Prevention and Attention at HIV/AIDS and STI in Hermosillo, Mexico. Participants mean age was 37.02 year old, 59.7%> were male and 40.3%> females. Three consecutive statistical testing procedures were applied for data analysis: the Student t test for comparison of means and for assesing the comprehensibility of the questions; an exploratory factorial analysis with varimax rotation for determining construct validity; Cronbach's a coefficient for determining reliability. In 19 out of a total of 20 questions, the Student t test for comparison of means gave statistically significant values. A three-factors structure was found with the factorial analysis, with values above 1 that, taken as a whole, explain 56.13%> of the variance. An overall a coefficient of 0.887 was obtained with the test of reliability. According with the results obtained, the Zung' depression scale has optimal psychometric properties of construct validity and reliability for people with HIV
