CAS Co-Occurring Disorders & Dual Diagnosis 2 — Questions and Answers
Question 1: Which mental health disorder most frequently co-occurs with alcohol use disorder?
- Major depressive disorder (Correct answer)
- Schizophrenia
- Borderline personality disorder
- Obsessive-compulsive disorder
Correct answer: Major depressive disorder
Major depressive disorder is the most prevalent co-occurring mental health condition among individuals with alcohol use disorder, with depression and alcohol misuse each worsening the other.
Question 2: A counselor is treating a client with PTSD and opioid use disorder. Which therapeutic approach has the strongest evidence base for treating both conditions simultaneously?
- Seeking Safety (Correct answer)
- Motivational Interviewing alone
- 12-Step facilitation only
- Psychoeducation without trauma processing
Correct answer: Seeking Safety
Seeking Safety is an evidence-based, present-focused therapy specifically designed to treat co-occurring PTSD and substance use disorders concurrently.
Question 3: When distinguishing between a substance-induced mood disorder and an independent major depressive episode, the CAS should evaluate symptoms:
- During a period of sustained abstinence of at least 4 weeks (Correct answer)
- Only while the client is actively using
- Immediately upon intake before any detox
- Using only self-report instruments
Correct answer: During a period of sustained abstinence of at least 4 weeks
Evaluating depressive symptoms after at least 4 weeks of abstinence helps determine whether the mood disorder persists independently of substance use.
Question 4: Integrated Dual Disorder Treatment (IDDT) is characterized by which core feature?
- One treatment team addresses both mental health and substance use in a coordinated manner (Correct answer)
- Mental health and substance use are treated in separate, specialized programs
- Medication management is the primary intervention for both disorders
- Clients must achieve sobriety before mental health treatment begins
Correct answer: One treatment team addresses both mental health and substance use in a coordinated manner
IDDT integrates mental health and substance use treatment within a single program and treatment team, eliminating the need for clients to navigate separate systems.
Question 5: Clients with co-occurring bipolar disorder and stimulant use disorder are at elevated risk for:
- Manic episode precipitation and cycle acceleration (Correct answer)
- Reduced impulsivity during manic phases
- Lower rates of psychosis compared to stimulant users without bipolar
- Spontaneous remission without intervention
Correct answer: Manic episode precipitation and cycle acceleration
Stimulant use can trigger or worsen manic episodes and accelerate mood cycling in individuals with bipolar disorder, significantly complicating clinical management.
Question 6: In a co-occurring disorder context, 'diagnostic overshadowing' refers to:
- Attributing mental health symptoms solely to substance use, thereby missing an independent psychiatric diagnosis (Correct answer)
- Over-prescribing psychiatric medication to substance-involved clients
- Using substance use history to overshadow family system factors
- Prioritizing diagnostic labeling over client-centered care
Correct answer: Attributing mental health symptoms solely to substance use, thereby missing an independent psychiatric diagnosis
Diagnostic overshadowing occurs when clinicians attribute all presenting symptoms to the substance use disorder, causing them to miss or delay identifying an independent mental health diagnosis.
Question 7: Which stage of the IDDT model focuses on helping clients who are not yet acknowledging their co-occurring disorder engage with treatment?
- Engagement stage
- Active treatment stage
- Relapse prevention stage
- Persuasion stage (Correct answer)
Correct answer: Persuasion stage
The persuasion stage of IDDT targets clients who are engaged in services but not yet motivated to work on their co-occurring disorders, building readiness for change.
