These ADHD screening tools focus on attention, organization, hyperactivity, impulsivity, and related functional impact. They can support reflection or a structured discussion with a clinician, teacher, or caregiver, while diagnosis still requires a full professional assessment.
The first distinction is who the questionnaire describes and who answers it. ASRS asks adults about their own attention, organisation and activity. Vanderbilt gathers an observer's account of a child's behaviour and functioning.
Look beyond a single setting. Attention during homework, routine work, social activities and highly engaging tasks can differ. A description of where difficulties appear, how long they have existed and what they disrupt adds information to either form.
Sleep, worry, mood and changing demands are also relevant when discussing concentration. Select the age-appropriate questionnaire first, then bring examples from daily life rather than treating adult and child scores as comparable.
Use administration method, audience, and purpose to choose an appropriate educational or screening resource.
The adult ASRS questionnaire asks about attention, organisation, restlessness and impulsive behaviour in everyday situations.
The Vanderbilt questionnaire organises an observer's account of a child's attention, activity and behaviour.
