Objective: Dysregulated emotional behavior occurs often in adults with ADHD. Analysis of clinical trials may guide clinical intervention and future research. Method: Controlled trials of adult ADHD measuring emotional behavior were included if another study offered a comparable analysis of the same treatment method. Standardized Mean Difference (SMD) of effects were calculated, and the size of effects for emotional and non-emotional ADHD behavior were compared. Results: 13 out of 14 studies of methylphenidate, atomoxetine, and lisdexamfetamine demonstrated significant improvement in emotional behavior measures, with small to high SMDs. The proportional effect on emotional versus non-emotional behavior ranged from 46% to 110% for methylphenidate, 56% to 129% for atomoxetine, and 36% to 96% for lisdexamfetamine. Conclusion: Psychopharmacological treatments for ADHD are likely to improve emotional behavior, and available scales are sensitive to these effects. Studies dedicated to treatment of this domain of function can further refine clinical approaches.
