The strengths and difficulties questionnaire: The self-report version in American urban and suburban youth.

This study examined the factor structure of the Strengths and Difficulties Questionnaire (SDQ) in urban inner-city and suburban general population samples of American youth. The SDQ was administered to 4,661 predominantly minority urban youth (mean age = 13.0 years, SD = 2.02) and 937 predominantly Caucasian suburban youth (mean age = 14.0 years, SD = 1.56). The authors examined SDQ factor structure using structural equation modeling techniques. The fit for the 5-factor models in both samples was very good (comparative fit index = .96-.97). However, the factor loadings and, correspondingly, the scale reliabilities for most of the SDQ scales (except for Emotional Problems) were low, which suggests poor specificity of the items. Subsequent exploratory and confirmatory factor analyses suggested that a 3-factor structure had a comparable model fit and better internal consistency of the scales. The study concluded that, although the SDQ scales do conform reasonably well to a 5-factor model, the scales are unsatisfactory in other respects and that, in its present form, the instrument has inadequate psychometric characteristics. Future research is needed for further scale development. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

The Strengths and Difficulties Questionnaire in the Bergen Child Study: A conceptually and methodically motivated structural analysis.

Objective: To test Goodman’s theoretical 5-factor model of the Strengths and Difficulties Questionnaire (SDQ) in an analysis of the Norwegian parent (P) and teacher (T) versions of the questionnaire. Method: The T-SDQ was analyzed for 8,999 (95.4% of all) children in primary school grades 2–4 in Bergen, Norway, whereas the P-SDQ was examined for 6,430 children (68.2%). Main analyses were exploratory and confirmatory factor analyses. Results: The analyses supported a modestly modified version of Goodman’s 5-factor model for both the P-SDQ and the T-SDQ. The correlations between latent factors were high, particularly when the conduct problem factor was involved, reflecting a high level of overlap between the problem areas. Cross-informant correlation between parents and teachers was moderate to high for the problem subscales and considerably higher than the corresponding correlation between subscales that has been found in earlier studies. Conclusions: None of the alternative models derived from the exploratory factor analysis fitted the data better than a slightly modified version of Goodman’s 5-factor model, which showed acceptable goodness of fit.
