Attention-Deficit/Hyperactivity Disorder (ADHD) Checklist

This checklist is designed as a measure of disorder symptomatology. It must be interpreted in the context of individual client circumstances and as such should be used only in combination with a comprehensive medical and clinical assessment. It is NOT a stand-alone diagnostic tool.

ADHD is characterised by symptoms from one or both of the following categories:

Inattention Symptoms

  • Poor attention to detail

  • Difficulty sustaining attention

  • Does not seem to listen when spoken to

  • Difficulties remaining on-task and completing tasks

  • Poor organisation skills

  • Reluctance to engage in tasks involving¬†sustained mental effort

  • Often losing things

  • Forgetfulness

  • Distractibility

Hyperactivity and Impulsivity

  • Fidgeting often

  • Unable to sit still

  • Unable to play quietly

  • Often running around and climbing in inappropriate situations

  • Restlessness

  • Excessive talking

  • Impatience

  • Often interrupts people

If a child, adolescent or adult has experienced 6 or more symptoms from one or both of these categories consistently for at least 6 months, they may meet criteria for an ADHD diagnosis. In this case, it is recommended that they be referred to a psychologist for a more comprehensive assessment.
