WGU D573: Understanding Substance Abuse & Addiction

Why D573 Lands on Health and Psychology Degree Plans

Understanding Substance Abuse & Addiction (course code D573) is a Leavitt School of Health course. WGU describes it as an overview of the causes, impact, prevention, and treatment of substance abuse, covering the signs and symptoms of addiction and its effect on individuals, groups, and the community, and asking students to describe evidence-based strategies for prevention, intervention, and treatment. It appears on the course lists for programs including the B.S. Health and Human Services and the B.S. Psychology, and WGU's institutional catalog lists it at 3 competency units.

Direct answer: D573 is passed by submitting written performance assessment work, not by sitting a proctored multiple-choice test. Read the task prompt and its rubric before you read a single chapter, then write directly to each rubric point using the course materials as your evidence base. Submissions usually come back not because the student misunderstood addiction, but because a required element of the prompt went unanswered.

Students in this course are usually headed toward community health, case management, human services, behavioral health support, or a graduate path in counseling or psychology — which shapes how you should study it. The skills D573 asks for (describing a substance use disorder accurately, thinking about a specific population, and proposing prevention or intervention grounded in evidence rather than opinion) are the same skills you will use on the job and in later coursework such as D402 Community and Public Health and D396 Evidence-Based Practice for Health and Human Services.

One more reason to take it seriously: the subject is personal for a lot of people in the class. If you have watched addiction move through your own family, expect some readings to land harder than a typical course. That is normal, and it does not mean you are the wrong person for this work.

What the D573 Assessment Actually Asks You to Do

D573 is assessed through written performance assessment tasks that you submit through your course of study, where an evaluator scores them against a rubric. There is no proctored sitting and no trick questions — but there is also no partial credit for a well-written paper that leaves a required element out. Task wording and course codes are revised from time to time, so treat the prompt inside your own course of study as the authority over anything you read online, including this guide.

Working from WGU's published course description and from what students consistently describe writing about, plan to be comfortable with these areas:

• How substance use, misuse, dependence, and substance use disorder are defined and distinguished from one another
• Major substance categories and their effects — alcohol, cannabis, opioids, stimulants, sedatives, and tobacco or nicotine
• Short-term versus long-term physical, cognitive, and behavioral effects of a given substance
• Contributing factors across the biological, psychological, and social domains, including risk and protective factors
• Signs, symptoms, and behavioral indicators that suggest a substance use problem
• Impact of substance use on families, workplaces, and communities, not just on the individual
• Prevention concepts, including universal, selective, and indicated approaches, and what makes a prevention program evidence-based
• Treatment and recovery supports, including how detoxification, treatment, harm reduction, and long-term recovery support differ
• Considerations for specific populations — adolescents, older adults, pregnant women, veterans, and culturally distinct communities
• Ethical, legal, and stigma-related issues in how substance use is discussed and treated

How Hard D573 Is, and How Long It Really Takes

Students generally describe D573 as moderate: conceptually dense but not mathematically or technically hard. The reading volume is the usual complaint. Anecdotally, students report finishing in roughly two to four weeks at a normal working-adult pace, with strong writers who already have a health or psychology background sometimes moving faster and students newer to academic writing taking longer. Treat that as a rough planning figure, not a promise.

What drives the timeline is almost never the content — it is the revision cycle. Every submission that comes back for revision adds evaluator turnaround time on top of your rewriting time. Budget for one revision even if you expect to pass on the first attempt, and start early enough in your term that a returned task is an inconvenience rather than a crisis. If academic writing itself is the sticking point, brushing up with the habits from C455 English Composition I pays off here more than extra reading does.

A Practical Study Plan for a Writing-Assessed Course

Because D573 is graded on submitted work, "studying" means building a small, accurate body of knowledge you can cite, then writing tightly to the rubric. Try this sequence:

1. Days 1-2: reverse-engineer the rubric. Open the task prompt and copy every required element into a document as its own heading. That document becomes the skeleton of your submission. If the prompt asks for a set number of considerations, you now have that many headings staring at you.
2. Days 3-6: read with a purpose. Read the course materials only to fill your skeleton. Take notes in your own words, and record the source and location for anything you may cite. Copy-pasting into notes is how accidental plagiarism happens weeks later.
3. Ongoing: active recall on the vocabulary. Make a short flashcard set for the distinctions that get confused under pressure — dependence versus tolerance versus withdrawal, misuse versus disorder, prevention versus treatment versus harm reduction. Test yourself from memory rather than rereading; rereading feels productive and teaches almost nothing.
4. Ongoing: spaced review. Revisit that card set for ten minutes every other day rather than an hour once. The terms need to be automatic by the time you are writing.
5. Days 7-9: choose narrow and specific. When the task lets you choose a substance and a population, pick a pairing you can support with real sources — for example, opioid use disorder among rural older adults rather than "drugs among people." Specificity is what makes the rest of the writing easy.
6. Days 10-12: draft, then self-evaluate as if you were the grader. Read your draft with the rubric beside it and mark where each required element is satisfied. Any element you cannot point to is a revision waiting to happen.
7. Before submitting: run it past the WGU Writing Center or a course instructor session. A twenty-minute review is cheaper than a returned task.

If you are pairing D573 with other Leavitt courses this term, the same rubric-first method transfers directly to D568 Health Equity and Social Determinants of Health, which shares a lot of the population-level thinking D573 rewards.

Where D573 Submissions Go Wrong

• Writing an essay instead of answering the prompt. Beautiful prose that wanders past a required element still comes back. Use headings that mirror the rubric language.
• Choosing a population that is too broad. "Teenagers" is a demographic; "high school students in a low-income urban district" is something you can actually plan a prevention program for.
• Proposing a prevention approach with no evidence behind it. If you cannot name a source or an established approach supporting your plan, the evaluator has nothing to score as evidence-based.
• Describing a substance instead of applying it. Pharmacology detail is not the point. The point is what that substance does to your chosen population and what should be done about it.
• Thin or missing citations. Attribute course materials and outside sources in the required format. This is the single easiest thing to fix and one of the most common reasons for a return.
• Moralizing instead of assessing. Language that treats substance use as a character failure reads as unprofessional in a health course. Use person-first, clinical framing.
• Reusing your own or someone else's work. Performance assessments are checked for originality. Purchased or shared "example" tasks are an academic integrity violation, not a shortcut.

D573 Readiness Checklist

• Can you explain, in plain language, the difference between substance misuse, dependence, and a diagnosable substance use disorder?
• Can you list the short-term and long-term effects of your chosen substance without looking at your notes?
• Can you name biological, psychological, and social risk factors — and at least two protective factors — for substance use?
• Can you describe the signs and symptoms someone might notice in a person developing a substance use problem?
• Can you name a specific population and state three concrete considerations that make prevention or treatment different for that group?
• Can you outline a prevention or intervention approach and point to the evidence supporting it?
• Can you explain the difference between treatment, harm reduction, and long-term recovery support?
• Have you matched every required element of the task prompt to a specific section of your draft?
• Has someone other than you — the Writing Center, an instructor, or a peer — read your draft before you submit it?

D573 FAQ

Is D573 an objective assessment or a performance assessment?

Students consistently report that D573 is assessed through written performance assessment tasks rather than a proctored objective assessment. Confirm the format inside your own course of study, since WGU periodically updates how courses are assessed.

How many competency units is D573 worth?

WGU's institutional catalog lists the course at 3 competency units.

How long does D573 usually take?

Students commonly describe finishing in roughly two to four weeks alongside work and family obligations. The variable that most often stretches that timeline is a returned task and the evaluator turnaround that comes with it, so start earlier than you think you need to.

Is D573 a hard course?

Most students call it moderate. The content is readable but dense, and the challenge is disciplined writing rather than difficult concepts. If you are comfortable following a rubric closely and citing sources, you are most of the way there.

Do I need a psychology or healthcare background first?

No. WGU lists no prerequisites for the course and writes it as an overview that assumes no clinical training. If the behavioral science vocabulary feels unfamiliar, a quick refresher from an introductory course like C180 Introduction to Psychology makes the readings go faster.

What should I do if my task comes back for revision?

Read the evaluator's comments literally and fix only what they flagged, element by element. A returned task is a routine part of how performance assessments work — it is feedback on specific gaps, not a verdict on you. Address each point directly and resubmit.
