Clinical Vignette
Patient: "Mr. D," 38-year-old engineer, presenting 3 weeks after being laid off from his job of 12 years.
Chief Concern: "I was laid off 3 weeks ago. Since then, I've been sad, can't concentrate, withdraw from people, and feel hopeless about my future. I've never felt like this before. Everything was fine before I lost my job."
History of Present Illness: Mr. D was unexpectedly laid off 3 weeks ago during corporate restructuring. He had no prior psychiatric history and describes his premorbid functioning as 'good — stable marriage, enjoyed hobbies, slept fine.' Since the layoff: (1) depressed mood (persistent sadness, tearfulness when thinking about the job), (2) difficulty concentrating (cannot focus on job applications), (3) social withdrawal (canceled plans with friends, stays home), (4) hopelessness about finding a new job (but NOT about life in general), (5) insomnia (initial insomnia, 30-45 minutes sleep onset latency — but NOT 2+ hours). He DOES NOT meet full MDD criteria: (1) appetite is normal, (2) no weight change, (3) no psychomotor changes, (4) no fatigue beyond normal, (5) no worthlessness/guilt, (6) no suicidal ideation, (7) insomnia is mild. His symptoms are DIRECTLY related to the layoff: he does not feel hopeless about life, only about employment. He retains interest in activities (watches sports, plays with his children) though at reduced intensity. His distress is proportional to the stressor but EXCEEDS what would be expected for a routine job loss.
Past Psychiatric History: No prior psychiatric history. No prior depressive episodes.
Mental Status Exam: Well-groomed. Speech normal. Mood 'sad about the job.' Affect mildly dysphoric but reactive (smiled when discussing his children). No psychomotor changes. Sleep: mild onset insomnia. Appetite normal. No SI. No guilt or worthlessness. Hopelessness is DOMAIN-SPECIFIC (employment only, not generalized).
Step 1: Adjustment Disorder DSM-5-TR Criteria
Criterion A: Development of emotional or behavioral symptoms in response to an identifiable stressor, occurring within 3 months of the onset of the stressor.
Symptoms began within days of layoff (3 weeks ago). Identifiable stressor: unexpected job termination. Within 3-month window. MET.
Criterion B: Symptoms are clinically significant as evidenced by: (1) marked distress out of proportion to the stressor, or (2) significant impairment in functioning.
Distress exceeds expected response to job loss (social withdrawal, concentration impairment, persistent sadness). Functional impairment: cannot focus on job applications, canceled social engagements. MET — both (1) AND (2).
Criterion C: Does not meet criteria for another mental disorder and is not an exacerbation of a preexisting condition.
Does NOT meet MDD criteria (missing 4 of 9 symptoms). No prior psychiatric condition. First episode of psychiatric symptoms. MET.
Criterion D: Not normal bereavement.
Stressor is job loss, not bereavement. MET.
Criterion E: Once the stressor has terminated, symptoms do not persist for >6 months.
Cannot yet assess (ongoing — stressor still present: unemployed). Expected to resolve with re-employment or adaptation. EXPECTED — monitoring required.
SUBTYPE: With depressed mood (predominant symptoms are sadness, tearfulness, hopelessness).
Primary symptoms are depressive: sadness, hopelessness about employment, tearfulness. SUBTYPE: DEPRESSED MOOD.
Step 2: Adjustment Disorder vs. MDD
| Feature | Adjustment Disorder | MDD | This Patient |
|---|---|---|---|
| Identifiable stressor | Required (within 3 months) | Not required (may or may not have stressor) | Adjustment Disorder: clear stressor (layoff) |
| Symptom count | Subsyndromal (does NOT meet full MDD criteria) | ≥5 of 9 symptoms for ≥2 weeks | Only 3 of 9 MDD symptoms |
| Symptom scope | Often domain-specific | Pervasive across all domains | Domain-specific: employment hopelessness only |
| Expected course | Resolves when stressor resolves (within 6 months) | May persist indefinitely without treatment | Expected to resolve with adaptation |
| Functional impairment | Present but proportional | Often disproportionate | Present, proportional |
Monitoring Priority
If Mr. D's symptoms progress to meet full MDD criteria (e.g., develops worthlessness, anhedonia generalizes, weight change, SI), the diagnosis should be changed to MDD. Adjustment Disorder is a WATCHFUL diagnosis that may evolve into a full depressive episode.
Diagnostic Formulation
Diagnostic Conclusion
Adjustment Disorder with Depressed Mood, Acute (F43.21): All DSM-5-TR criteria met. Subsyndromal depressive response to identifiable stressor (job loss). Does not meet MDD criteria. Specifier: acute (<6 months). Treatment: (1) Supportive psychotherapy (processing the loss, problem-solving for re-employment). (2) Cognitive restructuring (challenging catastrophic employment thoughts). (3) Behavioral activation (maintain social engagement, exercise, routine). (4) Monitor for progression to MDD (if symptoms worsen, broaden, or persist >6 months after stressor resolution, reassess diagnosis). Pharmacotherapy: generally NOT indicated for adjustment disorder. Reserved for cases that progress to MDD.
Teaching Points
- Adjustment Disorder is a 'subthreshold' diagnosis: it captures clinically significant distress related to a stressor that does NOT meet criteria for another specific disorder (MDD, PTSD, GAD). It is the most common psychiatric diagnosis in some clinical settings and serves as a clinical 'holding pattern' for stressor-related distress.
- The key distinguishing feature between Adjustment Disorder and MDD is SYMPTOM COUNT: Adjustment Disorder symptoms are subsyndromal (fewer than the 5 of 9 criteria required for MDD). Mr. D has 3 depressive symptoms (sadness, concentration difficulty, hopelessness), which is below the MDD threshold.
- Adjustment Disorder is inherently TIME-LIMITED: symptoms should resolve within 6 months of the stressor's termination (or adaptation to the stressor). If symptoms persist beyond 6 months after the stressor ends, the diagnosis should be reconsidered (possibly reclassified as persistent depressive disorder or MDD if criteria are met).
- Pharmacotherapy is generally NOT first-line for Adjustment Disorder. The evidence base supports supportive therapy, psychoeducation, and brief psychotherapy (cognitive-behavioral or problem-solving approaches). Prescribing antidepressants for subsyndromal, time-limited distress risks medicalization of normal stress responses.
- Adjustment Disorder is a MONITORING diagnosis: clinicians should reassess at regular intervals because a proportion of patients with initial Adjustment Disorder will progress to full MDD if the stressor persists or additional vulnerabilities emerge. Mr. D should be reassessed at 4-6 weeks for symptom progression.
