ADHD Assessment Checklist (CADDRA)
CADDRA's ADHD Assessment Checklist is a clinical tool for identifying attention-deficit/hyperactivity disorder (ADHD) and structuring its assessment. Used within the framework of the Canadian guidelines, it helps the psychologist or clinician review the core symptoms of ADHD according to current diagnostic criteria, as well as their functional impact in different life settings. The tool fits into a multimodal approach that includes the clinical interview, the developmental history, screening for comorbidities and, if possible, information from relatives, teachers or other professionals. It is particularly useful for standardizing the examination of inattention and hyperactivity-impulsivity symptoms, but it should not be interpreted as a stand-alone diagnostic instrument. In clinical practice, the CADDRA checklist is mainly used to support the initial assessment and the structured documentation of ADHD in children, adolescents and adults.

Scoring & interpretation
The checklist covers the 18 main ADHD symptoms, generally rated on a frequency or severity scale. In practice, responses corresponding to a frequent presence of the symptom are considered clinically significant. Interpretation is based on the number of inattention and/or hyperactivity-impulsivity symptoms present, with a usual threshold of 6 symptoms per domain in children and adolescents, and 5 symptoms per domain from age 17. Interpretation must also take into account functional impairment, the presence of difficulties in at least two settings, how long-standing they are over the course of development, and the differential diagnosis. The checklist alone is not sufficient to make a diagnosis.
