Gör man en testsökning på ncbi på 'addiction personality traits' får man exempelvis upp
en sån här studie (bara som exempel), citat ur dess abstract "
The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes // Notable personality distinctions were found // Whereas impulsivity and neuroticism were higher across all addiction populations ... people with alcohol use disorders also scored significantly lower on the traits of extraversion, agreeableness, and openness to experience. People with drug use disorders and those with compulsive sexual behavior were surprisingly similar, scoring lowest on the traits of agreeableness and conscientiousness. Finally, people with gambling disorder demonstrated a personality profile similar to that of the control group // These findings may provide a useful framework for understanding why different people develop different addictions". Det var väl en bra start för vidare diskussion.
