Abstract Background: Dimensional models of personality disorders, as outlined in the ICD-11 and AMPD, may offer insights in how maladaptive personality traits, such as negative affectivity, detachment, anankastia, psychoticism, and disinhibition may be associated with substance use behaviors.

Aim: In this talk we will present preliminary data from the EARY project regarding maladaptive personality traits and substance use in adolescence.

Methods: 196 participants (mean age: 13.95 years; 47.34% female) from community-based and clinical samples were analyzed. Maladaptive personality traits were assessed using the Personality Inventory for DSM-5 - Brief Form Modified Children and Adolescents (PID-5BF+ MA). Substance use was measured using the WHO Alcohol, Smoking and Substance Involvement Screening Test (WHO ASSIST). Linear regression models were conducted.

Results: A linear regression model explained 11.35 % of the variance in overall substance use (R2 = 0.1135, p = 0.0001). Regarding maladaptive personality trait domains, disinhibition was found to be the only significant predictor (β = 2.013, p = 0.014), with higher disinhibition scores being associated with higher substance use.

Conclusion: The findings highlight disinhibition as a key factor associated with substance use in adolescents. However, most of the variance remains unexplained, indicating that substance use is a complex behavior influenced by multiple factors. The findings emphasize the need to address impulsivity and risk-taking behavior in prevention and intervention programs targeting adolescent substance use.
