Emotional or behavioral symptoms within 3 months of an identifiable stressor, resolving within 6 months of stressor end.
Also known as: adjustment disorder, situational reaction
Overview
Development of emotional or behavioral symptoms in response to an identifiable stressor occurring within 3 months of the stressor onset, with marked distress out of proportion to the stressor or significant impairment, that do not meet criteria for another mental disorder. Symptoms resolve within 6 months of stressor termination.
Epidemiology
Common — point prevalence in primary care ~5%, higher in oncology and acute medical settings. All ages affected.

Question 1PsychiatryMedium
A 45-year-old man presents 3 weeks after losing his job with depressed mood, difficulty sleeping, and reduced motivation that he attributes directly to the job loss. He still enjoys time with his children, his appetite is unchanged, and he denies worthlessness, guilt, or thoughts of self-harm. He has no prior psychiatric history. Which of the following is the most likely diagnosis?

Why Adjustment disorder is correct
Emotional symptoms (depressed mood, insomnia, reduced motivation) developed within 3 months of an identifiable stressor (job loss) and are causing distress
The reaction does not meet criteria for another mental disorder — he has only three depressive symptoms with preserved enjoyment, appetite, and self-worth
Symptoms typically resolve within 6 months of the stressor or its consequences ending; treatment is supportive psychotherapy, problem-solving therapy, or cognitive behavioral therapy (CBT)
Why the others are wrong
Major depressive disorder — requires at least 5 of 9 symptoms for 2 or more weeks; this patient has only three, with preserved interest and appetite and no worthlessness or suicidal ideation (premature closure on 'depressed after a loss')
Persistent depressive disorder — requires depressed mood on most days for at least 2 years; 3 weeks of symptoms cannot qualify (buzzword-matching chronic-sounding low mood)
Acute stress disorder — requires exposure to actual or threatened death, serious injury, or sexual violence plus intrusion, dissociative, or arousal symptoms; job loss is not a qualifying traumatic event and none of those symptoms are present (the 3-day-to-1-month window is the tempting hook)
Question 2PsychiatryMedium
A 34-year-old man presents 6 weeks after being laid off from his job. He reports low mood, frequent worry about finances, and trouble falling asleep, and he has withdrawn from his usual social activities. He feels overwhelmed and says the distress is interfering with his ability to look for new work. He denies anhedonia, weight change, psychomotor changes, worthlessness, or thoughts of death, and he describes good days when he is distracted by friends. There is no history of prior psychiatric illness or substance use. PHQ-9 is 8, and physical examination and TSH are normal. Which of the following is the most likely diagnosis?
AAdjustment disorder
BMajor depressive disorder
CGeneralized anxiety disorder
DPersistent depressive disorder

Why Adjustment disorder is correct
Emotional symptoms (depressed mood, anxiety, sleep disturbance, withdrawal) began within 3 months of an identifiable stressor (job loss), are out of proportion and cause functional impairment, yet do not meet full criteria for another disorder — the DSM-5-TR definition of adjustment disorder.
It is a diagnosis of exclusion: the absence of a full major depressive episode, a chronic depressive course, or a discrete anxiety disorder is what makes adjustment disorder (with mixed anxiety and depressed mood) the best fit.
First-line management is brief supportive or problem-solving psychotherapy and addressing the stressor (e.g., social-work/financial resources); many cases self-limit, with reassessment if symptoms persist beyond 6 months after the stressor resolves.
Why the others are wrong
Major depressive disorder — requires 5 or more SIGECAPS symptoms for at least 2 weeks; he denies anhedonia, weight/appetite change, psychomotor changes, worthlessness, and death thoughts (PHQ-9 only 8), so full MDE criteria are not met.
Generalized anxiety disorder — needs excessive, difficult-to-control worry about multiple domains for at least 6 months; his worry is recent, tied to one stressor, and far short of that duration.
Persistent depressive disorder — requires depressed mood on most days for at least 2 years; his symptoms began 6 weeks ago after a discrete stressor and he has no prior psychiatric history, so the duration criterion is not met.
