Comparison of Outcomes Between Matched Respondents with Diagnosed ADHD and With Symptomatic ADHD (Unadjusted).

Note. p values are derived from two-sample t-tests. WPAI:GH = Work Productivity and Activity Impairment questionnaire: General Health; SDS = Sheehan Disability Scale; EQ-5D-5L = EuroQoL five-dimensional, five-level questionnaire; EQ VAS = EuroQoL visual analog scale.

^aFor employed respondents only (ADHD-diagnosed respondents, n = 172; symptomatic respondents, n = 232). WPAI:GH outcomes are expressed as impairment percentages; higher numbers indicate greater impairment and less productivity.

^bSDS total scores range from 0 (unimpaired) to 30 (highly impaired). Subscale scores range from 0 to 10; scores of ≥ 5 are associated with significant functional impairment.

^cEQ-5D Index (Utility) value summarizes EQ-5D-5L questionnaire responses as a single number on a scale anchored at 1 (full health) and 0 (dead).

^dPatients score their health state between 0 (the worst imaginable health state) and 100 (the best imaginable health state) on a 20 cm vertical graduated scale.

^eTotal scores range from 0 to 30 with high scores reflecting strong self-esteem; a score <15 may indicate problematic low self-esteem.
