Child/adolescent mental health screening. 25 items, 5 subscales.

The Strengths and Difficulties Questionnaire (SDQ), developed by Robert Goodman (1997), is a 25-item behavioral screening questionnaire for children and adolescents aged 4-17. It assesses five subscales: Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Peer Relationship Problems, and Prosocial Behavior. The SDQ is translated into over 80 languages and provides both total difficulties scores and subscale scores with established cut-off points.
