|Short Description of Instrument||
The SDQ is a screening measure for detecting behavior problems. There are multiple versions of the SDQ, depending on the age of the child, and the specific person completing the form (e.g. teacher/ parent, self-completion).
May be completed by children 11-16, or by parents or teachers of children 4-16. It can be completed in about 5 minutes using paper and pencil.
Questions are answered on a 3-point Likert scale. The score for each scale is the sum of item scores, generating a scale score from 0-10. A total difficulties score (from scores for hyperactivity, emotional symptoms, conduct problems and peer problems) ranges from 0-40.
