The purpose of the current study was to investigate the manifestation of ADHD in adults using a combination of structured clinical interview, behavioral self-report, and a range of neuropsychological measures. Symptom criteria that are endorsed by adults with ADHD as compared to non-diagnosed adults and an adult sample with other clinical disorders tend to reflect problems with follow-through, forgetting, organization, and losing things. Notably, adults in the No Diagnosis group endorsed a higher frequency of symptoms than base rates reported elsewhere. Related to sense of time, adults with ADHD endorsed problems with meeting deadlines, not completing tasks, not planning ahead, and having a poorer sense of time significantly more frequently than adults in either the No-Diagnosis or Other Clinical Disorder group. Results highlighted the need for further research specific to the manifestation of ADHD in adulthood and the development of diagnostic criteria that take into account the differences in development as well as age-related differences in contextual demands.
