A PsychInfo search (8/05) of “Strengths and Difficulties Questionnaire” or SDQ” anywhere revealed that the measure has been referenced in 329 peer-reviewed journal articles. Note: Because it was not possible to conduct a search that identified which specific version of the SDQ (Parent, Teacher, Child Self-Report) was used, this number represents the total for all SDQ versions. However, the articles cited below (for the most part) included the Parent version. The number is most likely an underestimate, given that the SDQ is internationally used and citations in foreign journals may not all be included in PsychInfo. 1. Achenbach, T. M., McConaughy, S.
