Behavioural management of defiance and oppositional behaviours — branching viva

Stem

The examiner starts with a 7-year-old referred for defiance at home and school, then adds ADHD features, a waitlist for parent training, and a safeguarding concern. [4]

Branch 1 — Definition and banding

Examiner: What is oppositional defiant disorder, and how do you separate it from normal noncompliance and from conduct disorder? [4]

Strong answer: ODD is a persistent pattern of angry/irritable mood, argumentative/defiant behaviour and vindictiveness with impairment, typically lasting months rather than days. Normative noncompliance is age-expected, limited and less impairing. Conduct disorder adds aggression to people or animals, property destruction, deceit/theft or serious rule violations. ODD can precede CD but is not the same. [4]

Examiner: Name Stringaris’s dimensions and why they matter. [2]

Strong answer: Irritable, headstrong and hurtful. They have different longitudinal predictions — irritability more toward internalising pathways; headstrong/hurtful more toward externalising/conduct risk — so follow-up targets differ. [2]

Branch 2 — Mechanism

Examiner: Explain the coercive family cycle in plain registrar language. [9]

Strong answer: Parent gives a demand; child refuses or escalates; parent withdraws the demand or explodes. The child escapes the demand in the short term, so noncompliance is reinforced. The parent feels defeated and becomes harsher or more avoidant. Parent training targets those contingencies. [9]

Branch 3 — First-line treatment

Examiner: What is first-line treatment and what evidence do you cite? [5] [11]

Strong answer: Behavioural parent training with active practice. Scott’s multicentre BMJ trial showed parenting groups work in real clinical practice. Kaminski’s meta-analysis highlights positive parent–child interaction, consistent discipline, emotional communication and practice with the child. Programme families include Oregon-model lineage, Incredible Years-type groups and PCIT for younger children. [5] [11]

Examiner: The parent training waitlist is six months. What do you do this month? [5]

Strong answer: Interim coached skills in clinic/telehealth, written simple plan, school consistency, safety plan, and advocacy for earlier access. Do not default to antipsychotic for mild defiance because of a waitlist. [5] [6]

Branch 4 — ADHD comorbidity

Examiner: School describes impulsivity, incomplete work and motor restlessness as well as talking back. How does that change care? [18]

Strong answer: Assess for ADHD properly and treat if confirmed using paediatric ADHD guidance (Wolraich). Treating ADHD often reduces secondary oppositional symptoms. Continue parent training for residual coercive patterns. [18] [6]

Branch 5 — Medication limits

Examiner: When, if ever, would you consider medication for disruptive/aggressive behaviour? [6]

Strong answer: After psychosocial measures, for severe aggression in specialist pathways, often after ADHD is treated. Canadian Gorman guidance emphasises selective use and monitoring. Risperidone has RCT evidence in specific disruptive populations under specialist care. Avoid benzodiazepines as behaviour management. Mild ODD arguing alone is not an antipsychotic indication. [6]

Branch 6 — Trajectory and intensity

Examiner: What is Moffitt’s dual taxonomy and when do you escalate intensity? [8] [12]

Strong answer: Life-course-persistent versus adolescence-limited antisocial pathways. Early multi-problem onset with ADHD and adversity needs earlier multi-system intensity. Severe complex CD may need MST-type ecological interventions (Henggeler). [8] [12]

Branch 7 — Safeguarding

Examiner: During history the mother discloses partner violence and the child is hit “when he won’t listen.” What now? [4]

Strong answer: Protect first. Follow mandatory reporting and safety planning. Do not run a pure compliance curriculum that increases risk. Behaviour formulation continues only inside a safety frame. [4]

Closing pearl

Examiner: One sentence for the notes. [4]

Strong answer: Multi-informant ODD-range formulation with coercive-cycle maintainers; parent training and school plan first-line; ADHD screen/treat; no antipsychotic for mild defiance; safety net for escalation and safeguarding. [4] [5] [18]
