“…In the absence of a scale with evidence of reliability and validity in Chile that assesses SDS, in this study the objective was to establish evidence of validity of the DSS for its use on Chilean university students, analyzing its factorial structure, internal consistency, evidence of convergent and discriminant validity, as well as exploring the differences in the SDS according to sex. First of all, and according to the hypothesis, our findings were consistent with the unidimensional structure of the scale in the original study (Caron et al, 1993), and studies on its psychometric properties for its use in the US (Greene & Faulkner, 2005), Spain Ubillos et al, 2016), El Salvador (Sierra & Gutiérrez-Quintanilla, 2007), Brazil (Sierra et al, 2009), and Peru , although we did not observe the unanimous difficulty identified on the low discriminative capacity of item 8, the only inverse item on the DSS, by studies in Spain in its version for adolescents, El Salvador, Brazil, and Peru, nor in any other item (see Table 1). On the other hand, although items 3 and 8 reached adequate skewness and kurtosis, and corrected item-total correlations and factor loadings over .5, we observed a slight improvement in the internal consistency of the scale with its elimination.…”
