Strengths and Difficulties Questionnaire (SDQ)

The SDQ is a brief behavioral screener for 4-17 year olds created by Goodman in 1997. This measure can be used as a screener for risk for psychiatric disorders. The SDQ focuses on positive attributes as well as risk symptoms regarding the child or adolescent’s behavior in the past six months. There are multiple versions of the measure: teacher report for ages 4-11 and 11-17, parent report for ages 4-17, and child self-report for 11-17 year olds. Additionally, there is an early childhood SDQ for 2-4 year olds. Each questionnaire includes 25 items. An overall Total Difficulties Score is produced, along with five subscale scores: Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Relationship Problems, and Prosocial Behavior. Optional Internalizing and Externalizing scales may also be produced. An optional impact supplement is also included on the longer form version which provides further information about chronicity, distress, social impairment, and burden to others. There are also follow-up versions of the questionnaire, which include additional questions along with a shorter time period to detect change after intervention. The SDQ has been translated into over ninety languages.
