Dual diagnosis (DD) is the co-occurrence, in the same person, of a mentaldisorder (MD) and a substance use disorder (SUD). Nowadays, the study ofthe personality with DD is realized mainly from a categorical view, focusingon the detection of personality disorders and not on the traits associated to DD and the possible differential profile compared to those patients with only MD or SUD. Studies analyzing personality traits of patients with DD and their possible differential profile are very limited. However, existing data indicates that DD patients show higher levels of Sensation Seeking, Impulsivity, Harm Avoidance and Neuroticism; and lower levels of Persistence, Self-Direction, Self-Transcendence and Cooperation. Therefore,DD is associated to personality characteristics that suggest more disruptivebehaviors, fewer resources for recovering and keeping abstinent and worseprognosis compared to those with only one disorder. Progress in thecharacterization of personality traits in DD, taking into consideration themethodological aspects to be improved could allow better adaptation of theintegrated treatment of these patients in the future.References
