Comparison of Quality of Life, Productivity, Functioning and Self-Esteem in Adults Diagnosed With ADHD and With Symptomatic ADHD.

Objective

Investigate the association between diagnosis and outcomes in adults with symptoms of ADHD. Method: The Validate Attitudes and Lifestyle Issues in Depression, ADHD and Troubles with Eating (VALIDATE) study collected sociodemographic and clinical characteristics data, and responses from validated questionnaires on health-related quality of life (HRQoL), work productivity, functioning, and self-esteem. ADHD-diagnosed respondents (n = 444) were matched with respondents with symptomatic ADHD (n = 1,055) within the same sex-by-age group using propensity score matching. Effects of ADHD diagnosis on each outcome were adjusted for covariates that remained imbalanced after matching, using generalized mixed models.

Results

After matching, symptomatic respondents (n = 867) had worse outcomes than ADHD-diagnosed respondents (n = 436), as measured by the Work Productivity and Activity Impairment: General Health questionnaire and Sheehan Disability Scale (p < .001). ADHD-diagnosed respondents had better mean EuroQol five-dimensional five-level (EQ-5D-5L) scores and Rosenberg Self-Esteem Scale scores than symptomatic respondents (p < .001).

Conclusion

ADHD-diagnosed individuals are more likely to experience better functional performance, work-related productivity, HRQoL, and self-esteem than individuals with symptomatic ADHD.
