A Test Score Answers a Particular Question
Psychological tests provide structured information about the abilities or symptoms they measure. The meaning of a score depends on the measure, the referral question, and the rest of the evaluation. No single test diagnoses ADHD.
The Evaluator Looks Across Sources
ADHD assessment may include clinical interviews, developmental history, symptom ratings, records, and information about functioning in different settings. Cognitive measures can help describe strengths and challenges. A diagnosis should not be made solely from a rating scale or an observation.
Neither Scores nor Symptoms Stand Alone
Typical cognitive scores do not automatically settle an ADHD question. Reported difficulties do not establish ADHD on their own either. The evaluator must determine whether the overall evidence supports diagnostic criteria, meaningful impairment, and the timing and pattern of symptoms.
Use Feedback to Understand the Reasoning
Ask what the tests measured, which findings support the conclusions, what remains uncertain, and which other explanations were considered. Sleep difficulties, anxiety, depression, and learning concerns can also affect attention. Even when a hoped-for diagnosis is not supported, feedback can identify next steps for addressing your concerns.
