Severity and symptoms: Study links alcohol use disorder to other psychiatric conditions

Alcohol use disorder (AUD) is more common among people who have another, co-occuring psychiatric condition (e.g., depression or ADHD), and vice versa. These links are well established, and are based on meeting diagnostic criteria for one or other disorder. However, investigating associations based on strict ‘yes/no’ diagnoses does not account for people who may have a range of psychiatric symptoms and yet do not meet the threshold for a diagnosis of any single disorder.
