This is a clinician-written, evidence-based summary aligned to the 2026 MLA Content Map. It is intended for medical students and junior doctors preparing for the UKMLA. Always cross-reference with NICE guidance, local protocols, and clinical judgement.
Key points
- Emotional/behavioural symptoms developing within 3 months of an identifiable stressor
- Symptoms are out of proportion to the stressor (accounting for cultural norms) and cause functional impairment
- Diagnosis of exclusion — must NOT meet criteria for depression, PTSD, GAD, or bereavement disorder
- Usually self-limiting — resolves within 6 months of the stressor or its consequences ceasing
- Management: supportive counselling, brief psychological intervention, problem-solving therapy
- Risk assessment is important — suicide risk is elevated in adjustment disorder despite its "mild" reputation
Overview
Adjustment disorder is a maladaptive response to an identifiable psychosocial stressor or life change, developing within 3 months of the stressor onset. Symptoms can include low mood, anxiety, worry, irritability, difficulty coping, and behavioural disturbance, but they do not meet the full diagnostic criteria for a specific mental health disorder such as depression, GAD, or PTSD. The stressor can be any life event: relationship breakdown, bereavement, redundancy, illness diagnosis, moving house, financial difficulties, or interpersonal conflict. Adjustment disorder is classified in ICD-11 under disorders specifically associated with stress. It is typically self-limiting, resolving within 6 months once the stressor ceases or adaptation occurs.
Epidemiology
Adjustment disorder is one of the most commonly diagnosed psychiatric conditions in liaison psychiatry and primary care, though its prevalence is difficult to quantify precisely due to variable diagnostic thresholds. Estimates suggest it accounts for 5–20% of outpatient psychiatric consultations. It can affect any age group but is commonly seen after major life transitions (adolescence, retirement, bereavement). Risk factors include limited social support, poor coping skills, pre-existing personality traits, concurrent stressors, and previous mental health history. Importantly, adjustment disorder carries a meaningful suicide risk — it should not be dismissed as trivial.
Clinical Features
Symptoms
Low mood, tearfulness, feelings of hopelessness — but not meeting full criteria for depression
Anxiety, worry, nervousness — but not pervasive enough for GAD
Difficulty concentrating, feeling overwhelmed, unable to plan ahead
Irritability, angry outbursts, behavioural disturbance (especially in adolescents)
Sleep disturbance, appetite change
Social withdrawal and reduced functional capacity
Suicidal ideation — risk is genuinely elevated
Signs
Tearfulness, distress when discussing the stressor
Normal mental state examination apart from emotional reactivity related to the stressor
No psychotic features, no pervasive anhedonia (cf. depression)
Investigations
First-line
Clinical assessmentIdentify the stressor, timeline, symptom profile, and functional impairment. Determine whether criteria for another disorder (depression, PTSD, GAD) are met
Risk assessmentSuicide risk is elevated — always assess ideation, intent, plan, protective factors
Second-line
PHQ-9 and GAD-7To help distinguish from depression and GAD. Scores typically subthreshold for full diagnosis
Specialist
Psychiatric reviewIf symptoms persist >6 months, escalate in severity, or diagnostic uncertainty (rule out emerging depression, PTSD, personality disorder)
1
Supportive care
- Validation and normalisation of emotional response to the stressor
- Brief supportive counselling: problem-solving focus, enhancing coping strategies
- Social prescribing: signposting to relevant support services (bereavement support, financial advice, relationship counselling)
2
Psychological intervention
- Brief psychological intervention: 4–6 sessions of problem-solving therapy, brief CBT, or interpersonal therapy
- Group support if stressor is shared (e.g. bereavement groups, redundancy support)
- Crisis intervention if acute risk identified
3
Pharmacotherapy (limited role)
- Antidepressants NOT routinely recommended — symptoms are subthreshold
- Short-term anxiolytic or hypnotic may be considered (e.g. zopiclone for acute insomnia) — very short course only
- If symptoms evolve to meet criteria for depression or GAD → treat per respective guidelines
4
Follow-up and safety-netting
- Review at 2–4 weeks — most cases resolve within 6 months
- If symptoms persist, escalate, or new criteria are met → reassess diagnosis
- Clear safety-netting for worsening symptoms, suicidal thoughts, or functional decline
Complications
- Progression to depression: If stressor persists or coping fails, may evolve into major depressive episode
- Suicide: Risk is genuinely elevated — do not underestimate. Assessment is essential
- Substance misuse: Coping with alcohol or drugs
- Occupational and social dysfunction: May lose employment, strain relationships
- Chronic adjustment: If poorly managed, maladaptive patterns may become entrenched
UKMLA Exam Tips
- 1Adjustment disorder is a DIAGNOSIS OF EXCLUSION — must not meet criteria for depression, GAD, or PTSD
- 2Key distinction from PTSD: the stressor in adjustment disorder is NOT a qualifying trauma (life-threatening, sexual violence)
- 3Key distinction from depression: symptoms do not meet full criteria (e.g. <5 symptoms, or <2 weeks)
- 4Develops within 3 MONTHS of the stressor. Resolves within 6 MONTHS of the stressor or its consequences ending
- 5Suicide risk is elevated — always assess even though the label sounds "mild"
- 6In exams: patient presents with distress after a life event but symptoms do not fit a specific disorder → adjustment disorder
