LAGOS-SAN MARTIN, Nelly et al. Self-Description Questionnaire II (short version): evidence of reliability and validity in a sample of chilean adolescents. rev.latinoam.psicol. [online]. 2016, vol.48, n.1, pp.69-79. ISSN 0120-0534.  https://doi.org/10.1016/j.rlp.2015.04.001.

This study sought to analyse the reliability and validity of the scores from the Short Version of the Self-Description Questionnaire II (SDQ-II-S). The sample consisted of 1255 Chilean adolescents with an age range of 13-17 years (M=15.10; SD = 1.30). Confirmatory factor analyses verified the original correlated 11-factor structure of the SDQ-II-S. The multidimensionality of the questionnaire was also supported by small magnitude of correlations among factors (M = 0.26). Cronbach's alpha coefficients ranged from 0.70 to 0.84, showing adequate reliability. For further analyses of the construct validity of SDQ-II-S, scores of the different scales were related to scores on anxiety (State Anxiety Inventory-Trait) and self-efficacy measurements (Academic Situations Specific Perceived Self-Efficacy Scale). The results revealed that those questionnaires assess different -yet related - constructs. The data presented indicate that the SDQ-II-S shows adequate psychometric properties in the Chilean population, thereby countering the current scarcity of appropriate self-concept assessment measurements, and displaying interesting applications both in the applied and research areas.
