CAMPO-ARIAS, Adalberto; HERAZO, Edwin e CABALLERO-DOMINGUEZ, Carmen Cecilia. Dimensionality, nomological validity and internal consistency of the brief Davidson scale for post-traumatic stress in students from Santa Marta, Colombia. Rev. Fac. Nac. Salud Pública [online]. 2020, vol.38, n.3, e339851. Epub 01-Dez-2020. ISSN 0120-386X. https://doi.org/10.17533/udea.rfnsp.e339851.
Objective:
To determine the dimensionality, nomological validity and internal consistency of the brief Davidson scale for post-traumatic stress in average vocational students from Santa Marta, Colombia.
Methodology:
In the second semester of 2018, a total of 1,462 tenth and eleventh grade students aged between 13 and 17 years old (M = 16.0; DE = 0.8), 60.3% female, filled out the brief Davidson scale for post-traumatic stress. Exploratory and confirmatory factor analyses were performed. The internal consistency of the dimension was calculated with Cronbach’s alpha and McDonald’s omega coefficients.
Results:
In the exploratory factor analysis, the brief Davidson scale for post-traumatic stress showed Kaiser-Meier-Olkin = 0.714, Barttlet’s chi square = 783.3 (gl = 6; p = 0.001), and an eigenvalue of 1.99, which explained 49.7% of the variance. In the confirmatory factor analysis, chi square = 5.921; gl = 2; p = 0.052; root of the mean square of the error of approximation = 0.037 (CI 90% 0.000-0.072); comparative adjustment index = 0.955; Tucker-Lewis index = 0.985 standardized mean square residual = 0.011. Cronbach’s alpha was 0.66, and McDonald’s omega was 0.69.
Conclusions:
The brief Davidson scale for post-traumatic stress is one-dimensional, with acceptable internal consistency.
