ADHD Assessments


If you are experiencing difficulties with concentration, inattention, impulsivity, and/or hyperactivity, then an ADHD assessment may be recommended. An ADHD assessment may be beneficial in assisting you with your ADHD treatment. 

ADHD Criteria

As per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), several criteria must be met for an individual to qualify for an ADHD diagnosis. In particular:

  • Symptoms need to be excessive for the developmental age of the individual
  • Symptoms must be present before the age of 12
  • Symptoms must persist for more than 6 months 
  • Symptoms are present in more than one setting
  • Symptoms interfere with social, academic, and/or occupational functioning
Assessment Process
  • Initial Consultation: This is a 1-hour ADHD interview (with the adult client) that is focused on gathering relevant background information including but not limited to, personal background, family history, medical and mental health background, performance during school as well as during employment, and any symptoms pertaining to inattention and/or hyperactivity and impulsivity (both during childhood and currently). The ADHD interview is completed in conjunction with the DSM-V ADHD criteria, as well as other screener tools.
  • Cognitive Assessment: The WAIS-IV is administered during a 2-hour appointment to assess for general intelligence. The WAIS-IV is helpful in understanding an individual’s cognitive ability and factors such as working memory and processing speed which may be limited in adults with ADHD.
  • Psychologist Report: The treating psychologist will prepare a report based on the aforementioned interview, cognitive assessment, as well as other standardised tests and reports to provide a clinical judgment of ADHD. This is based on 3-4 hours of service.
