WHAT THE TEST MEASURES

About This Assessment

Strengths and Difficulties Questionnaire (SDQ) Test

adaptation deviations

This brief questionnaire is used to screen for behavioral and emotional concerns and to document strengths in children and adolescents. The Strengths and Difficulties Questionnaire (SDQ) is commonly used in clinical, educational, and research settings to support early identification and triage.

The measure includes 25 items and typically takes about 5 minutes to complete. Versions are available for caregiver and teacher report, and a youth self-report format is used in older children/adolescents; results are interpreted as screening indicators rather than diagnostic findings. The Strengths and Difficulties Questionnaire (SDQ) is attributed to Robert N. Goodman and is intended to provide a structured snapshot across key domains of functioning (e.g., emotional symptoms, conduct problems, hyperactivity/inattention, peer problems, and prosocial behavior) to inform follow-up assessment and monitoring over time.
