Substance Use Disorders on the LCSW Exam: Assessment and Treatment

Substance Use Disorders on the LCSW Exam

Substance use disorders are a major area of focus on the ASWB Clinical exam. Questions cover the full spectrum of clinical practice, from screening and assessment to treatment and relapse prevention. Given the high prevalence of substance use issues among clinical social work clients, you must be well-versed in current best practices for assessment and intervention.

DSM-5-TR Substance Use Disorder Criteria

The DSM-5-TR combines the previously separate categories of substance abuse and substance dependence into a single diagnosis of substance use disorder, with severity specified based on the number of criteria met:

• Mild: Two to three criteria met
• Moderate: Four to five criteria met
• Severe: Six or more criteria met

The 11 criteria for substance use disorder include impaired control (using more than intended, inability to cut down, cravings, excessive time spent using), social impairment (failure to fulfill obligations, continued use despite social problems, giving up activities), risky use (physically hazardous use, continued use despite physical or psychological problems), and pharmacological indicators (tolerance and withdrawal).

Screening and Assessment

Screening Tools

The exam may reference commonly used screening instruments. Know the following:

• CAGE questionnaire: Four questions about cutting down, annoyance at criticism, guilt, and eye-opener drinking
• AUDIT (Alcohol Use Disorders Identification Test): A 10-item screening tool developed by the WHO for identifying hazardous alcohol use
• DAST (Drug Abuse Screening Test): A screening tool for drug use problems
• SBIRT (Screening, Brief Intervention, and Referral to Treatment): A comprehensive approach to identifying and addressing substance use in healthcare settings

Comprehensive Assessment

A thorough substance use assessment includes the client's history of use (substances, frequency, quantity, route of administration), consequences of use, previous treatment attempts, family history of substance use, co-occurring mental health conditions, and current motivation for change. On the exam, remember that assessment should be conducted in a non-judgmental, empathic manner consistent with motivational interviewing principles.

Evidence-Based Treatments

Motivational Interviewing

Motivational interviewing is a first-line intervention for substance use disorders, particularly for clients in the precontemplation or contemplation stages of change. It focuses on exploring and resolving ambivalence about change through empathic, non-confrontational dialogue. On the exam, MI is almost always the correct approach when a client is resistant to change or unsure about stopping substance use.

Cognitive Behavioral Therapy

CBT for substance use disorders focuses on identifying and modifying the thoughts and behaviors that maintain substance use. Key components include functional analysis of substance use, development of coping skills, and relapse prevention strategies. CBT is effective for a wide range of substance use disorders and is well-supported by research.

Contingency Management

Contingency management uses tangible reinforcers (such as vouchers or prizes) to reward abstinence and treatment compliance. While it may seem simple, contingency management has strong empirical support for treating substance use disorders, particularly stimulant use disorders for which no medication-assisted treatment is available.

Medication-Assisted Treatment

While social workers do not prescribe medications, you should know the major medication-assisted treatments for the exam:

• Alcohol use disorder: Naltrexone (reduces cravings), acamprosate (reduces withdrawal symptoms), disulfiram (causes unpleasant reaction to alcohol)
• Opioid use disorder: Methadone (full agonist, administered through licensed clinics), buprenorphine (partial agonist, can be prescribed in office settings), naltrexone (antagonist that blocks opioid effects)

Co-occurring Disorders

Many clients with substance use disorders also have co-occurring mental health conditions such as depression, anxiety, PTSD, or personality disorders. The exam tests your knowledge of integrated treatment approaches that address both conditions simultaneously rather than treating them sequentially. Integrated treatment is considered the best practice for co-occurring disorders.

Relapse Prevention

Relapse prevention is a key component of substance use disorder treatment. Developed by G. Alan Marlatt, the relapse prevention model teaches clients to identify high-risk situations, develop coping strategies, and understand the abstinence violation effect (the tendency to give up completely after a single lapse). On the exam, remember that relapse is often part of the recovery process and should be addressed therapeutically rather than punitively.
