The best way to clarify a diagnosis is with psychological testing.
Psychological testing will require your child to attend 3-8 hours of one-on-one testing. Assessments will include computer-based measures, pencil-and-paper activities, a clinical interview, and questionnaires. Your evaluation also includes: medical/academic record review, online behavioral rating scales completed by parent(s) and teacher(s), clinical interviews with any other providers, and a clinical interview with parent(s).
When all data is gathered, the report of results of testing should be ready within a few weeks. This report will provide detailed explanation of scores, clinical interpretation, and recommendations for support at home, school, and in treatment. You will be emailed the report in advance of a one-hour remote meeting (via Zoom or phone) to review results.
