Strengths and Difficulties Questionnaire

The SDQ can be administered by parents, teachers, or healthcare professionals who have been trained in its administration. The questionnaire can be completed either online or on paper. The person completing the questionnaire should read each question and check the appropriate box indicating how much they agree or disagree with each statement.

The SDQ assesses children's abilities and challenges across five subscales: Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Peer Relationship Problems, and Prosocial Behavior.

The SDQ results can be interpreted by adding the subscale and overall scores. Normal, borderline, and abnormal/high-risk scores are available. Higher Emotional Symptoms, Conduct Problems, and Hyperactivity/Inattention subscale scores indicate more difficulties, whereas higher Peer Relationship Problems and Prosocial Behavior subscale scores indicate more strengths.
