Abstract

Aims: To estimate Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist normative total scores among the US adult general population and to evaluate overall attention-deficit hyperactivity disorder (ADHD) symptom burden among US adults with ADHD.

Methods: Prior 2012 and 2013 US National Health and Wellness Survey respondents were re-contacted. Demographics, comorbidities, and ASRS-v1.1 data were collected. ASRS-v1.1 scores were compared by sex, age, ADHD diagnosis, and ADHD medication use. Group differences were evaluated using chi-square tests and independent samples t-tests for categorical and continuous variables, respectively.

Results: Of 22 397 respondents, 465 self-reported being diagnosed with ADHD by a physician; of these, 174 self-reported using ADHD medication. The mean ASRS-v1.1 total score was 2.0 (SD = 3.2); scores differed by age and sex (all, P < 0.001). ADHD (vs no ADHD) was associated with depression (58.1% vs 18.0%), anxiety (53.1% vs 16.0%), and sleep difficulties (37.0% vs 14.0%) (all, P < 0.001). ADHD medication use (vs no use) was associated with depression (68.4% vs 51.9%), anxiety (67.2% vs 44.7%), panic disorder (25.9% vs 17.2%), and insomnia (27.6% vs 19.6%) (all, P < 0.05). ADHD (vs no ADHD) respondents scored higher on all 18 ASRS-v1.1 items (all, P < 0.05). Medication users (vs non-users) scored higher on six items (all, P < 0.05).

Discussion: Adult ADHD may be undertreated or sub-optimally treated, despite a high symptom burden. Normative data will allow comparisons with individuals' scores to support the assessment of ADHD symptom burden among adults.

Conclusion: Findings highlight the importance of assessing ADHD symptom burden, especially among adults presenting with comorbidities.
