The psychometric properties of the Self-Description Ques tionnaire-II (SDQ-II) were assessed with an American middle school sample comprising 291 students. Results revealed acceptable internal consistency and four-week stability coefficients for all domain scores and the Total score of the instrument. The results of confirmatory factor analyses supported the convergent validity of the SDQ-II. Although the hypothesized factor structure provided a reasonable fit to the data, the relatively high intercorrelations among some of the SDQ-II scales raised issues related to discriminant validity. Implications of the findings for future research with American children are discussed.
