CADC Co-Occurring Disorders 2 — Questions and Answers
Question 1: Which screening tool is specifically designed to identify co-occurring mental health disorders in individuals presenting for substance use treatment?
- AUDIT-C
- MAST
- MINI International Neuropsychiatric Interview (Correct answer)
- CAGE
Correct answer: MINI International Neuropsychiatric Interview
The MINI International Neuropsychiatric Interview is a structured diagnostic tool that screens for a broad range of DSM/ICD psychiatric disorders alongside substance use.
Question 2: A client with PTSD and alcohol use disorder reports using alcohol to manage nightmares. This pattern best illustrates which concept?
- Dual diagnosis escalation
- Self-medication hypothesis (Correct answer)
- Substance-induced anxiety disorder
- Tolerance transfer
Correct answer: Self-medication hypothesis
The self-medication hypothesis proposes that individuals use substances to alleviate symptoms of underlying psychiatric conditions like PTSD.
Question 3: When is it most appropriate to use a 'watch and wait' approach before diagnosing a co-occurring psychiatric disorder?
- When a client has a history of trauma
- When psychiatric symptoms emerged before substance use began
- When symptoms may be substance-induced and could resolve with abstinence (Correct answer)
- When the client refuses psychiatric medication
Correct answer: When symptoms may be substance-induced and could resolve with abstinence
Substance-induced disorders can mimic primary psychiatric conditions, so monitoring symptoms during early abstinence helps clarify a true co-occurring diagnosis.
Question 4: In integrated dual diagnosis treatment, services for substance use and mental health are best described as:
- Sequential and separate
- Parallel but uncoordinated
- Provided simultaneously by the same treatment team (Correct answer)
- Alternated based on which disorder is currently active
Correct answer: Provided simultaneously by the same treatment team
Integrated treatment combines substance use and mental health interventions within a single team, improving outcomes compared to sequential or parallel models.
Question 5: A counselor notices a client's depressive symptoms persist after 6 weeks of abstinence. The most likely clinical implication is:
- The depression is definitively substance-induced
- The client is not truly abstinent
- The depression is likely an independent co-occurring disorder requiring treatment (Correct answer)
- Antidepressants are contraindicated at this stage
Correct answer: The depression is likely an independent co-occurring disorder requiring treatment
Depressive symptoms lasting beyond 4–6 weeks of abstinence suggest an independent major depressive disorder rather than a substance-induced condition.
Question 6: Which of the following is a core feature of Dialectical Behavior Therapy (DBT) that makes it particularly useful for clients with co-occurring borderline personality disorder and substance use disorder?
- It focuses exclusively on relapse prevention
- It teaches distress tolerance and emotion regulation skills (Correct answer)
- It uses 12-step principles as its foundation
- It requires medication compliance as a prerequisite
Correct answer: It teaches distress tolerance and emotion regulation skills
DBT's distress tolerance and emotion regulation modules directly target the emotional dysregulation central to BPD and the impulsivity driving substance use.
Question 7: Which term describes the clinical situation where substance use and a psychiatric disorder each independently worsen the other?
- Comorbid tolerance
- Bidirectional exacerbation (Correct answer)
- Syndromal convergence
- Cross-sensitization
Correct answer: Bidirectional exacerbation
Bidirectional exacerbation occurs when each disorder independently amplifies symptoms and severity of the other, creating a cycle that complicates treatment.
