Strengths and Difficulties Questionnaire

The Strengths and Difficulties Questionnaire (SDQ), developed by Robert Goodman in 1997 and validated by 2001, is a brief 25-item behavioral screening instrument for children aged 2–17 years. Available in parent, teacher, and youth self-report versions, it assesses both emotional/behavioral difficulties and personal strengths, making it unique among screening tools. It is widely used in community, clinical, and research settings for rapid screening and population surveillance.
