Samenvatting	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.	The Vanderbilt Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale, developed by Mark Wolraich and colleagues in 2003, is a validated screening instrument for identifying ADHD symptoms and comorbid behavioral/emotional problems in children aged 6–12 years. Available in parent and teacher versions, it is widely used in primary care, pediatrics, and developmental clinics for initial ADHD screening and symptom tracking during treatment.
