Risk factors

  • Recent identifiable life stressor — job loss, divorce, illness diagnosis, bereavement, financial strain, immigration
  • Limited social support
  • Prior psychiatric illness
  • Concurrent medical illness

Pathophysiology

Maladaptive response to psychosocial stress reflecting interplay of stressor severity, coping resources, and pre-existing vulnerability.

Clinical presentation

Symptoms

  • Depressed mood, anxiety, mixed emotional features
  • Disturbance of conduct (more in adolescents)
  • Mixed disturbance of emotions and conduct
  • Functional decline, withdrawal, sleep changes, somatic complaints

Signs / physical exam

  • Distress evident on examination
  • No specific exam findings; rule out medical contributors

Differential diagnosis

  • Major depressive disorder — Meets full MDE criteria regardless of stressor
  • Generalized anxiety disorder / panic disorder — Meets full criteria for anxiety disorder
  • Acute stress disorder / PTSD — Stressor meets trauma criterion + symptom clusters
  • Bereavement — Normative grief; if persistent and impairing >=12 months, consider prolonged grief disorder
  • Other specified trauma- and stressor-related disorders — Symptoms do not fit any specific category

Diagnostic workup

Diagnostic criteria

DSM-5-TR: (A) Emotional/behavioral symptoms in response to identifiable stressor occurring within 3 months; (B) Symptoms are out of proportion to severity of stressor (considering cultural context) OR cause significant impairment; (C) Does not meet criteria for another mental disorder and is not exacerbation of pre-existing disorder; (D) Symptoms do not represent normative bereavement; (E) Once stressor (or its consequences) ends, symptoms resolve within additional 6 months. Specify: with depressed mood, anxiety, mixed, disturbance of conduct, mixed emotions/conduct, or unspecified.

Labs

  • TSH and basic labs to exclude medical contributors
  • Screening: PHQ-9, GAD-7, suicide risk assessment

Imaging

  • Not routinely indicated

Treatment

First-line

  • Brief supportive psychotherapy, problem-solving therapy, CBT
  • Behavioral activation, stress management, sleep hygiene
  • Social work and resource navigation for stressor (housing, finances, family)
  • Active monitoring and follow-up; many cases self-limit

Second-line / adjunct

  • Short-course pharmacotherapy targeting prominent symptom: SSRI/SNRI if symptoms persist or worsen; hypnotic for transient insomnia
  • Avoid chronic benzodiazepines
  • Reassess diagnosis if symptoms persist beyond 6 months — likely MDD, GAD, or persistent depressive disorder

Complications

  • Progression to MDD, anxiety disorder, or substance use
  • Suicide — elevated risk particularly in adolescents and oncology patients
  • Functional and occupational decline if untreated

PANCE pearls

  • Adjustment disorder is a diagnosis of exclusion — confirm symptoms do not meet criteria for MDD, GAD, PTSD, etc.
  • If symptoms persist >6 months after stressor resolution, the diagnosis no longer applies — reassess.
  • Even though adjustment disorder is 'less severe' by definition, suicide risk can be substantial — always assess.
  • Treat the stressor when possible (social work, financial counseling) — directly improves outcomes.
