Study Notes

Dual Diagnosis

Definition: Co-morbidity/Co-occurrence of two or more health problems, often referring to alcohol and drug issues in combination with mental health
Key distinction: Heterotypic (different classes of mental disorders) vs Homotypic (disorders within the same class)
Types of dual diagnosis: Concurrent (two or more disorders present at the same time) and Successive (disorders occur at different times in a person's life)
Continuum: ranging from mild symptoms to severe disorders, with individuals displaying a number of symptoms but not meeting criteria for a diagnosis referred to as having a 'subsyndromal' or 'partial' disorder

Incidence of Dual Diagnosis

42.9% of the population will experience a mental health disorder in their lifetime
21.5% of people experience a mental health disorder in the prior 12 months, with anxiety being the most common (17.2%)
38.8% of 16-24-year-olds had a mental health disorder in the prior 12 months
Having a mental health disorder increases the likelihood of substance use issues and vice versa
Dual diagnosis prevalence estimates range from 30-90%, varying based on diagnostic criteria and settings
Higher prevalence in Alcohol & Drug settings, treatment settings, and among Indigenous Australians

Prevalence in A&D Settings

48% of females with alcohol use disorder also have anxiety, affective, or drug use disorder
34% of males with alcohol use disorder had another mental disorder
Compared to 9% of males that didn't have alcohol use disorder
Increased risk of getting a second comorbid disorder is related to age of onset, persisting 10, 15, or more years later
