  • Title: Alexithymia, Impulsivity, and Reward Sensitivity in Young Adult University Student Children of Alcoholics.
    Author: Lyvers M, Hayatbakhsh N, Stalewski J, Thorberg FA.
    Journal: Subst Use Misuse; 2019; 54(2):340-344. PubMed ID: 30321089.
    Abstract:
    BACKGROUND AND OBJECTIVES: Personality traits previously known as risk factors for alcohol use disorder (AUD) were assessed in 29 young adult children of alcoholics (COAs) and 68 young adult children of nonalcoholics (non-COAs). Male and female university students (Mage = 22.11 years) completed questions pertaining to demographics and alcohol use, and the Children of Alcoholics Screening Test; Toronto Alexithymia Scale; Barratt Impulsiveness Scale; Sensitivity to Punishment and Sensitivity to Reward Questionnaire; and Depression Anxiety Stress Scales. RESULTS: Results indicated that personality traits of alexithymia, reward sensitivity, and impulsivity, as well as negative moods, were significantly elevated in COAs compared to non-COAs, independent of current alcohol consumption and drinking history. CONCLUSIONS: Findings are consistent with familial transmission of AUD-associated personality traits in COAs, presumably via influences of genetics and/or familial environment.
