Question 3: When assessing a new client with suspected co-occurring disorders, what is the recommended sequencing approach under integrated treatment models?
- Assess and treat both disorders concurrently (Correct answer)
- Treat the substance use disorder first, then address mental health
- Treat the mental health disorder first, then address substance use
- Refer out to separate specialists for each disorder
Correct answer: Assess and treat both disorders concurrently
Integrated treatment models recommend concurrent assessment and treatment of both disorders because they mutually influence each other.

- MINI International Neuropsychiatric Interview (MINI) (Correct answer)
- CAGE Questionnaire

Correct answer: MINI International Neuropsychiatric Interview (MINI)
The MINI is a structured diagnostic interview widely used to screen for a range of DSM-defined mental health disorders in co-occurring disorder settings.
Question 6: Substance-induced disorders differ from independent mental health disorders primarily because symptoms of substance-induced disorders:
- Resolve within a predictable period after cessation of substance use (Correct answer)
- Are always more severe than independent disorders
- Only occur during active intoxication
- Cannot be treated with medication
Correct answer: Resolve within a predictable period after cessation of substance use
Substance-induced disorders are expected to remit once the substance is discontinued, distinguishing them from independent mental health diagnoses that persist beyond the pharmacological effects.
Question 7: The 'quadrant model' for co-occurring disorders classifies clients based on which two dimensions?
- Severity of mental illness and severity of substance use disorder (Correct answer)
- Age of onset and type of substance used
- Level of motivation and treatment history
- Insurance status and diagnostic category
Correct answer: Severity of mental illness and severity of substance use disorder
The quadrant model, developed by NASMHPD and NASADAD, categorizes clients by the severity of their mental illness and the severity of their substance use disorder to guide service system placement.
