Updated October 2026 · 5 min read

CNSL 631 is UMGC's foundation course in addiction counseling, covering how addiction develops and what counselors do from first screening to a written treatment plan.

UMGC describes it as an overview of the addictive process and the practice of addiction counseling. It aims to build conceptual knowledge, practical skills and self-awareness about the etiology of substance abuse and addiction and their impact across the lifespan.

Workforce skills, such as writing required reports and keeping records, are part of the course.

The prerequisites are CNSL 621 and CNSL 622, with CNSL 606 and CNSL 624 as prerequisites or corequisites. It is a required core course and the gateway to the addiction electives.

What CNSL 631 Covers

Key Concepts Explained

Screening Versus Assessment

Screening is brief and asks whether a problem may be present; assessment is fuller and establishes the nature, severity and context of the problem. Short validated screening tools exist for alcohol and other drug use, and a positive screen leads to fuller assessment.

Example: A client at a community clinic completes a short alcohol screening questionnaire at intake and scores above the cut-off. That does not establish a diagnosis. The counselor follows up with a structured interview covering amount, frequency, loss of control, consequences, withdrawal and prior treatment before considering an alcohol use disorder diagnosis and its severity.

Severity in Diagnosis

Under the current DSM, substance use disorders are rated mild, moderate or severe by how many of the listed criteria are met. Assignments often ask you to count criteria explicitly from case facts.

Family Dynamics

Families can unintentionally maintain substance use, for example by covering consequences, and they can also be powerful supports for recovery. The course asks you to consider both.

Reports and Record-Keeping

UMGC names report writing and record-keeping as workforce applications, which reflects real practice: addiction services rely on clear intake summaries, treatment plans and progress notes for continuity, funding and legal reasons.

Good documentation is factual, dated, written in behavioral terms and free of judgment. Progress notes commonly follow a structured format such as SOAP (subjective, objective, assessment, plan). Confidentiality rules for substance use treatment records are strict in the United States, so expect to discuss what can be shared and with whose consent.

Typical Assignments and How to Approach Them

Treatment planLinking needs to servicesAddress substance use, health, family and co-occurring issues
Instrument reviewKnowledge of toolsCompare purpose, population and limits of two or three tools
Reflection on self-awarenessAttitudes towards addictionName your assumptions honestly and how you will manage them

Addiction Across the Lifespan

The course looks at substance use and its impact across the lifespan, and assignments often contrast age groups. Adolescents may present through school or family problems rather than asking for help, and early use is a concern because the brain is still developing.

Older adults may be overlooked because symptoms resemble other health problems, and interactions with prescribed medicines raise particular risks. Adults in mid-life often present with work, relationship or legal consequences.

Tailoring screening questions, settings and family involvement to the client's life stage shows the kind of practical judgment the course is building.
