What traits define an addictive personality?

The addictive personality refers to a proposed set of traits, such as impulsivity, sensation-seeking, and emotional dysregulation, that may increase a person's risk for various forms of addiction. While studies link specific personality profiles to addictive behaviors like gambling, shopping, or substance use, the concept remains controversial and lacks formal recognition in the DSM-5. Furthermore, genetic factors play a massive role in addiction vulnerability, accounting for an estimated 40% to 70% of individual risk variation.

What we know

• The proposed addictive personality construct includes traits like impulsivity, sensation-seeking, and emotional dysregulation. [2]
• Behaviors associated with the addictive personality hypothesis extend beyond substance use to include gambling, internet use, compulsive eating, and shopping. [2]
• Genetic factors contribute significantly to addiction vulnerability, with heritability estimates ranging from 40% to 70% of individual variation. [2]
• Trait theory defines personality aspects as habitual patterns of behavior, thought, and emotion that are relatively stable over time. [3]

Still open

• It remains debated whether personality traits serve as predictors of addiction or emerge as a consequence of addictive behaviors, and the term itself lacks a consistent definition.
