Foundations of Counseling: Assessment and Diagnosis - Substance Abuse Assessment, CAGE, AUDIT, Stages of Change

Substance Abuse Assessment (CAGE, AUDIT, Stages of Change) – Exam?Ready Study Guide

What This Is

Substance?abuse assessment is the systematic process of gathering information to determine a client’s pattern of alcohol or drug use, the severity of the problem, and readiness for change. It combines brief screening tools (CAGE, AUDIT) with a motivational framework (Stages of Change) so counselors can quickly identify risk, diagnose a use disorder per DSM?5?TR, and tailor interventions. Example: A 28?year?old client, “Mike,” presents for anxiety counseling. During the intake, the counselor asks the CAGE questions, discovers a “yes” on “Cut down,” and then uses the Stages of Change model to see that Mike is in the “Preparation” stage, prompting a brief motivational?interviewing (MI) intervention before any formal treatment plan is written.

Key Terms & Theories

• CAGE Questionnaire: Four?item screen (Cut down, Annoyed, Guilty, Eye?opener) for hazardous alcohol use; a score ?2 suggests a possible disorder.
• AUDIT (Alcohol Use Disorders Identification Test): 10?item WHO instrument; scores 0?7 low risk, 8?15 hazardous, 16?19 harmful, 20+ probable dependence.
• Stages of Change (Transtheoretical Model): Prochaska & DiClemente’s five (later six) phases—Precontemplation, Contemplation, Preparation, Action, Maintenance, (Termination). Guides motivational interviewing.
• Motivational Interviewing (MI): Rogers?influenced, client?centered technique that elicits change talk; core skills: open questions, affirmations, reflections, summaries (OARS).
• DSM?5?TR Substance?Use Disorder (SUD) Criteria: 11 criteria (e.g., tolerance, withdrawal, loss of control); 2–3 = mild, 4–5 = moderate, ?6 = severe.
• Screening, Brief Intervention, and Referral to Treatment (SBIRT): Public?health model that pairs CAGE/AUDIT screening with brief counseling and, when needed, referral.
• Harm?Reduction: A philosophy that accepts continued use while reducing negative consequences; often used when clients are not ready for abstinence.
• Relapse Prevention (RP): Marlatt & Gordon’s cognitive?behavioral strategy focusing on high?risk situations, coping skills, and self?efficacy.
• Confidentiality (ACA Code A.2.a): Counselors must protect client information unless a legal exception (e.g., Tarasoff duty) applies.
• Cultural Competence in Substance Use: Recognizing how cultural norms, stigma, and access to care influence patterns of use and willingness to disclose.

Step?by?Step / Process Flow

1. Build Rapport & Set the Frame – Use unconditional positive regard and open?ended questions (“Tell me about your drinking habits”).
2. Administer a Brief Screen – Give the CAGE (or AUDIT if you need a more detailed picture). Record answers verbatim.
3. Score & Interpret – Calculate the total; if ?2 on CAGE or ?8 on AUDIT, flag for possible SUD.
4. Assess Readiness – Ask “Where do you see yourself in terms of changing your drinking?” and map the response onto the Stages of Change.
5. Deliver a Targeted Intervention –
6. Precontemplation/Contemplation: Use reflective listening and explore ambivalence (MI).
7. Preparation/Action: Collaborate on a SMART goal (e.g., “Reduce drinks to ?2 per week for the next 30 days”).
8. Maintenance: Teach coping skills, relapse?prevention plans, and schedule follow?up.
9. Document & Plan Referral – Note screen scores, stage, and agreed?upon next steps; if severe (AUDIT?20 or DSM?5?TR ?6), arrange referral to specialized addiction services.

Common Mistakes

• Mistake: Skipping the screen because the client “looks fine.”
  Correction: Always administer CAGE/AUDIT; substance use can be hidden. Ethical duty (ACA A.2.b) requires thorough assessment.

• Mistake: Treating a “yes” on one CAGE item as a definitive diagnosis.
  Correction: Use the screen as a flag, then conduct a full DSM?5?TR interview to confirm SUD severity.

• Mistake: Assuming the client is in the “Action” stage because they say they want to quit.
  Correction: Probe for concrete plans and past attempts; many clients are still in “Preparation” or “Contemplation.”

• Mistake: Providing advice (“You should stop drinking”) instead of using MI.
  Correction: Use OARS to elicit change talk; directive advice can increase resistance and breach client autonomy (ACA B.2.c).

• Mistake: Neglecting confidentiality when documenting screen results.
  Correction: Store screening data securely, share only with consented parties, and follow ACA A.2.a.

NCE / Clinical Insights

1. Screen vs. Diagnosis: The NCE often asks you to differentiate a CAGE “screening tool” from a DSM?5?TR diagnosis. Remember: CAGE-flag; DSM?5?TR-11 criteria.
2. Stage Identification: Expect a vignette where a client says, “I’m not sure I have a problem, but my wife says I drink too much.” The correct answer is Contemplation (recognizing ambivalence).
3. Scoring Traps: On the AUDIT, a score of 8 is the cut?off for hazardous use; many test?takers mistakenly choose 7.
4. Ethical Duty to Warn vs. Confidentiality: The NCMHCE may present a scenario where a client discloses intent to drive intoxicated. The correct action is to break confidentiality (Tarasoff duty) because there is an imminent risk to identifiable others.

Quick Check Questions

1. Vignette: Jenna, 35, scores a 9 on the AUDIT and says, “I’m ready to cut back.” Which stage of change is she most likely in?
   Answer: Preparation* – she has decided to change and is planning concrete steps.

2. Vignette: During intake, a client answers “yes” to the CAGE “Eye?opener” question but denies any problems. What is the next best step?
   Answer:* Conduct a full DSM?5?TR substance?use interview to assess severity and explore readiness for change.

3. Vignette: A counselor uses the statement, “It sounds like you’re feeling stuck about your drinking.” Which MI skill is demonstrated?
   Answer: Reflection* – paraphrasing the client’s feeling to deepen self?exploration.

Last?Minute Cram Sheet (10 One?Liners)

1. CAGE = Cut, Annoyed, Guilty, Eye?opener; ?2 = possible AUD.
2. AUDIT cut?off = 8 for hazardous use; 20+ = probable dependence.
3. Stages of Change: Precontemplation-Contemplation-Preparation-Action-Maintenance? (Termination).
4. MI Core Skills = OARS (Open?ended, Affirm, Reflect, Summarize).
5. DSM?5?TR SUD: 11 criteria; 2?3 mild, 4?5 moderate, ?6 severe.
6. SBIRT = Screening, Brief Intervention, Referral to Treatment.
7. Tarasoff (1976)-Duty to Warn/protect identifiable third parties. Not a blanket breach of confidentiality.
8. ACA Code A.2.a = Confidentiality; B.2.c = Respect for client autonomy.
9. Harm?Reduction accepts continued use while minimizing harm; not “treatment failure.”
10. Relapse Prevention focuses on high?risk situations, coping self?efficacy, and “urge surfing.”

Use this guide to drill the core concepts, practice the screening tools, and master the decision?making logic the NCE/NCMHCE love to test. Good luck!
