  • Adjusted for age and gender (N=9203 for alcohol consumption and N=9056 for frequency of intoxication).

  • Significant associations in comparison to ‘Never consumed alcohol’ category in italic.

  • ASRS: Adult attention-deficit-hyperactivity disorder (ADHD) Self-report Scale, screening inventory for ADHD. ASRS inattention: the inattention subscale of the ASRS (9 items). ASRS hyperactivity: the hyperactivity-impulsivity subscale of the ASRS (nine items).

  • SMFQ: the short version of the Mood and Feelings Questionnaire, screening inventory for symptoms of depression and depressive disorders.

  • SCARED: five-item screening inventory for symptoms of anxiety and anxiety disorders.
