Personality differences related to smoking and adult attention deficit hyperactivity disorder.

Tridimensional Personality Questionnaire (TPQ) scores are compared for three groups of adults: (a) current smokers with Attention Deficit Hyperactivity Disorder (ADHDSmk, n = 14); (b) current smokers without ADHD (NonADHDSmk, n = 21); and (c) ADHD never smokers (ADHDNevSmk, n = 17). The ADHASmk participants started smoking at a significantly younger age than NonADHDSmk participants. On the TPQ Novelty Seeking (NS) scale, all groups scored more than a standard deviation above the norm, and ADHDSmk participants scored significantly higher than NonADHDSmk participants. The earlier onset of smoking in ADHD adults suggests that smoking prevention efforts may be particularly important for ADHD children. Previous studies have reported that both smokers and ADHD patients have elevated NS scores; this study suggests an additive effect for smokers with ADHD. This exaggerated tendency towards thrill seeking in ADHDSmk participants may complicate smoking-cessation treatment in this population, because the health consequences of smoking may be of less concern to ADHD smokers.
