Abstract

The purpose of this study was to establish Australian norms for the Strengths and Difficulties Questionnaire (SDQ), a recently developed screening instrument for child and adolescent mental health problems. A random sample consisting of 910 children aged 7–17 years recruited through government schools across Victoria, their parents and their teachers completed the appropriate version of the SDQ. The sample contained the expected spread of normal and abnormal scores according to the UK norms for the SDQ. As previous analyses have suggested that scores on the five subscales and the total difficulties scale of the SDQ may very with age and gender, separate norms for each of the three informant versions, by age and gender are presented in tabular form for children aged 7–17 years.
