Introduction:

Considering the current controversy regarding the factorial structure of the SDQ, this paper aimed to analyse the dimensionality and reliability of the parents’ version for children from 4 to 16 years of age, and to present descriptive data according to sociodemographic variables.

Method:

The factor structure of the original five- and three-factor models, and the reliability of the SDQ were examined among a sample of 621 parents of Uruguayan children between 7 and 12 years of age (52% girls) from different socioeconomic levels.

Results:

Confirmatory factor analyses did not provide support for the five- and three-factor models. Data adjusted to three factors (prosociality, externalising symptoms, internalising symptoms) in an exploratory analysis with adequate reliability indices.

Conclusions:

The results of this study show the relevance of continued investigation of the SDQ internal structure, and further analysis of the behaviour of several of its items.
