COU-650: Diagnosis of Emotional and Mental Disorders

A study guide to SNHU's COU-650, the graduate counseling course on making DSM diagnoses while questioning the medical model behind them.

Updated October 2026 · 5 min read

COU-650 at Southern New Hampshire University teaches counseling students to make diagnoses using the DSM, while asking what a medical diagnostic system means for the counseling profession.

SNHU's catalog describes understanding the value of, and controversies involved in, using medically based systems of diagnosis in counseling.

Students learn to make diagnoses using the DSM and relevant standardized assessment methods, consider client issues from alternative perspectives, and weigh the legal, ethical and multicultural issues in diagnosing clients.

The course is demanding because accuracy and critique must sit side by side. You need to apply criteria precisely, then step back and ask what the label adds, what it misses and how it could affect the client.

Key Concepts Explained

Criteria, Not Impressions

A DSM diagnosis requires the specified number of symptoms, for the required duration, causing clinically significant distress or impairment, and not better explained by another condition, a substance or a medical cause. Each of those parts needs evidence from the case.

Example: A vignette describes six weeks of low mood, loss of interest, poor sleep, fatigue and difficulty concentrating, with the client missing work. Before concluding major depressive disorder, a careful analysis checks the symptom count against the criteria, rules out substance use and medical causes, and asks about any history of manic or hypomanic episodes, which would point towards a bipolar-related diagnosis instead.

Differential Diagnosis

Many presentations fit more than one category. A differential lists plausible alternatives and explains, with case evidence, why each is chosen or ruled out.

Culture and Context

The DSM includes guidance on cultural concepts of distress and a Cultural Formulation Interview. Counseling assignments often ask how culture, identity and social stressors shape both the symptoms and the diagnostic decision.

Example: A recently arrived refugee reports poor sleep and headaches rather than sadness. A culturally informed analysis considers that distress may be expressed physically, explores trauma and resettlement stressors, and avoids assuming that the absence of the word "depressed" means the absence of depression.

Typical Assignments and How to Approach Them

Assignment typeWhat it testsHow to approach it
Diagnostic case analysisAccurate criteria useMap each symptom to a criterion
Differential diagnosisReasoning between optionsRule in or out with case evidence
Critical reflectionMedical model critiqueBalance benefits and harms of labels
Multicultural analysisCultural humilityUse the cultural formulation approach

Legal and Ethical Issues in Diagnosis

SNHU names legal, ethical and multicultural issues as part of the course. Assignments often ask you to discuss them alongside a case.

Linking these points to the ACA Code of Ethics, especially its sections on assessment and diagnosis, strengthens a reflection paper.

No. SNHU describes the value and controversies of medical diagnosis, alternative perspectives, and legal, ethical and multicultural issues as part of the course.

What is a differential diagnosis?

It is a list of plausible diagnoses for a case, with evidence explaining why each is chosen or ruled out.

How do I write a critical reflection on diagnosis?

Show you can apply the system accurately, then weigh its benefits, such as shared language and access to services, against risks such as stigma and cultural bias.
