A study by Mannuzza et al. (2002) found that adults with ADHD have difficulty accurately recalling their ADHD symptoms. Adults with ADHD (N=176) who had all received a previous diagnosis of ADHD in childhood were then interviewed by clinicians who were not aware of the subjects’ ADHD diagnosis. When the adults with ADHD were interviewed regarding their childhood symptoms, the clinicians were able to accurately diagnose ADHD in only 27% of the subjects. It was concluded that clinicians need to use additional information to evaluate childhood ADHD symptoms than primarily self-report.
