Children of parents with mental illness or substance use — OSCE · Paeds Cases

Prompt

Liam is an eight-year-old boy brought to the general paediatric clinic by his mother, Sarah, who has treatment-resistant depression. Liam has started missing school, complains of recurrent tummy aches, and has begun "looking after Mum" — reminding her to take her tablets and making his own lunch. Sarah is tearful and asks whether Liam is "going to get depressed too, because it runs in the family," and whether he should "see someone on his own." During the assessment Liam confides quietly that sometimes Mummy "doesn't wake up properly" and he has to get his little sister ready, and that last week Mummy drove them to school after taking her "calm-down tablets" that made her sleepy.

Candidate information (2 minutes reading, 12 minutes station)

You are the general paediatric registrar in an outpatient clinic. Liam, aged eight, is brought by his mother Sarah, who has treatment-resistant depression. Read the presentation, then conduct the assessment and counselling. The examiner will role-play Sarah. [1] [14]

Candidate tasks

Frame Liam's risk for Sarah without labelling him — explain the heightened-but-probabilistic nature of offspring risk and that this is a risk-and-need picture, not a diagnosis. [1] [6]
Identify the young-carer role and explain to Sarah why it is hidden need rather than good coping, and how it will be supported. [14]
Outline the two-generational plan, naming the evidence that treating the parent helps the child and the family-focused-prevention options. [7] [9]
Convert to safeguarding when Liam discloses that Sarah drove them to school after sedating medication. [1]

Model answer in one breath

Liam carries a heightened but probabilistic risk of emotional and behavioural disturbance — this is a risk-and-need picture, not a diagnosis, and I will not label a well child. His "looking after Mum" is a young-carer role — hidden need that erodes development and schooling — and I will arrange young-carer support. The plan is two-generational: optimise Sarah's depression treatment because a mother's remission measurably reduces her child's psychopathology, and deliver an evidence-based family-focused intervention such as the Beardslee or Solantaus programme with the family rather than Liam alone. The disclosure that Sarah drove the children after sedating medication is an acute child-safety concern — I convert to a safeguarding pathway, confirm who can look after the children safely today, and involve child protection where thresholds are met, before any family therapy proceeds.

Marking anchors

Distinction (PASS)

Frames offspring risk as heightened but probabilistic, explicitly states this is not a diagnosis and most exposed children remain well, and refuses to label Liam from his mother's history. [1] [6]
Names the young-carer role as hidden need, not resilience, and offers dedicated support while protecting schooling. [14]
Cites the Weissman STAR*D-child evidence that maternal remission reduces child psychopathology, and names family-focused prevention (Beardslee, Solantaus) delivered to the family. [7] [9] [10]
Converts to safeguarding the moment Liam discloses the sedated driving — confirms a safe carer today, makes a safety plan, and involves child protection, while maintaining a non-blaming stance toward Sarah's illness. [1]

Borderline

Names the risk but frames it deterministically ("he will probably get depressed"), or recommends child-only therapy as first-line, or recognises the safeguarding concern but defers it to "review in clinic." [6]

Fail

Labels Liam with a diagnosis from his mother's history, blames Sarah, prescribes or implies medication for Liam's "risk," endorses child-only therapy as the whole plan, or proceeds to "refer for counselling and review" despite the disclosed sedated driving. [1] [14]

Examiner prompt sequence

Opening (the mother): "Doctor, is he going to get depressed too, because it runs in the family?" — Candidate must frame the risk as heightened but probabilistic and avoid labelling. [1] [6]
The coping child: "But he's so good — he makes his own lunch and reminds me about my tablets." — Candidate must identify the young-carer role as hidden need. [14]
Treatment request: "Shouldn't he see someone on his own?" — Candidate must explain two-generational, family-focused care and that the active ingredient is the family. [9] [10]
The disclosure: Liam confides the sedated drive to school — candidate must convert to safeguarding. [1]
