Supporting Children with Oppositional Defiant Disorder: A Guide for NDIS Support Workers
This guide brings together current research and the practical experience we have gained supporting children with oppositional defiant disorder (ODD) and other disruptive behaviour problems across South East Queensland. Our hope is that by sharing what we have learned, more children, families and support workers can benefit from support that is respectful, person-centred and evidence-informed.

ODD is not "naughtiness" or a child being deliberately difficult. It is a pattern of persistent, developmentally inappropriate defiance, argumentativeness and irritability that sits on top of a child's existing neurodevelopmental profile and family context. Effective support is not about "getting the behaviour under control" or winning power struggles. It is about understanding how a child experiences their world, recognising that emotional regulation is genuinely hard work for them, working alongside families, and creating conditions where the child can practise new skills without shame.
At Hearts In Action, these principles guide the way we support children and families every day. This guide combines evidence from the research with practical insights from our work alongside children with ODD and their families. We hope it encourages thoughtful, compassionate support that helps children build skills, protects relationships and reduces the load parents are quietly carrying.
A note before you read on
Every child is unique, including every child with ODD. The patterns in this guide come from research, but no two children express oppositional behaviour in the same way, and no single strategy here will suit every family.
Use this guide as a way to build understanding while remaining open, curious and responsive to the child and family you are supporting. Their experiences, strengths, culture and goals should always guide the support they receive.
The Relationship Is Still the Intervention
Across ODD and other disruptive behaviour disorders, treatment reviews consistently find that outcomes depend as much on how adults relate to the child and family as on which specific program is used (Kaur et al., 2022). Qualitative research with parents of children diagnosed with ODD found that feeling judged by services and blamed for their child's behaviour made engagement harder, while non-judgemental, normalising support that acknowledged parents' own emotional needs made it easier to stay involved (Ljungström et al., 2020).
It's worth remembering
Be someone the child and family experience as on their side. You are working with them, not against them, and not "fixing" them. Calm, consistent presence and genuine respect do more for long-term change than any single behavioural technique.
Understand What ODD Actually Is
Oppositional defiant disorder is defined as a pattern of angry or irritable mood, argumentative or defiant behaviour, and vindictiveness lasting at least six months, beyond what is typical for the child's developmental stage and causing clear impact at home, school or in peer relationships (Mars et al., 2024). It sits within the broader group of disruptive behaviour disorders, alongside conduct disorder, and commonly co-occurs with ADHD, anxiety and autistic traits (Kaur et al., 2022). Critically, ODD involves difficulties in regulating emotions and behaviours rather than a lack of caring or a "bad attitude." Many children with ODD also meet criteria for ADHD, learning differences, or are children with disabilities who are navigating environments not designed for their sensory, cognitive or communication needs.
It's worth remembering
When a child refuses, argues or has an outburst, think "skills and stress" before "attitude." Emotional regulation, flexible thinking and problem-solving are developmental skills. For many children with ODD, those skills are still under construction.
See Behaviour as Communication, Not as a Moral Failing
Treatment guidelines and parent-training research emphasise that children's oppositional behaviour is often a signal that demands or expectations do not match their current skills or emotional state (Kaminski & Claussen, 2017). A child who argues about every instruction, melts down over transitions, or refuses work may be showing that tasks are too hard, instructions too vague, or that they are already overwhelmed by sensory or social stressors. Qualitative accounts from parents describe feeling "always on guard," constantly anticipating conflict, and noticing that difficult behaviours peak when everyone is tired, stressed or when routines break down (Ljungström et al., 2020). This pattern is particularly noticeable in families of children with disabilities, where day-to-day tasks (getting dressed, managing equipment, transitioning to appointments) already carry higher load.
It's worth remembering
Ask yourself "what might this behaviour be communicating?" before asking "how do I stop it?" Often the most effective support is reducing the mismatch between demands and skills rather than escalating consequences.
Support Families, Not Just Manage Behaviour
A qualitative study of parents of children diagnosed with ODD found three key domains of difficulty: parents' own vulnerability and mental health, the emotional strain of parent-child interactions, and challenges in everyday parenting practices (Ljungström et al., 2020). Parents described feeling isolated, ashamed and older than their years, with a sense of always being "on" and rarely getting genuine rest. These findings align with broader reviews noting that caregivers of children with disruptive behaviour problems carry high emotional and practical load and often lack supportive networks (Waddell et al., 2018).
It's worth remembering
Treat parental wellbeing as central, not peripheral. Ask how the parent is coping, what support they have, and what they need from you. A parent who feels believed, backed and less alone is more able to use any strategies you suggest.
Recognise the Neurodevelopmental and Disability Context
Children with ODD frequently have co-occurring ADHD, learning difficulties or are children with disabilities such as autism or intellectual disability, and their oppositional behaviour often arises in contexts where demands are not adjusted to their cognitive, sensory or communication profile. Systematic reviews of psychosocial treatments for disruptive behaviour identify a range of well-established, evidence-based programs for this broader population (McCart et al., 2022), and in general clinical practice these programs are often adapted when children have disabilities — for example by simplifying language, increasing visual supports, and involving schools and allied health teams.
It's worth remembering
Use person-first language ("children with ODD," "children with disabilities") and remember that oppositional behaviour is happening on top of an existing neurodevelopmental profile. Adjust expectations and strategies to that profile rather than pushing the child toward a neurotypical template.
Make Structure and Predictability Work for the Child, Not Against Them
Children with ODD benefit from clear, predictable routines and consistent limits, but research shows that the most effective structure is collaborative and tailored, not rigid or authoritarian. Parent Management Training and similar programs emphasise predictable schedules, clear rules and consistent follow-through, paired with high levels of labelled praise and positive attention for cooperation (Kaminski & Claussen, 2017). Qualitative parent data highlight that chaos in routines, shifting expectations between adults, and inconsistent follow-through intensify oppositional behaviour and leave parents feeling helpless (Ljungström et al., 2020). This is heightened for families of children with disabilities, where medical appointments, therapy and equipment changes already disrupt structure. This is the same consistency our personal care and daily living support is built around: routines delivered by the same people, the same way, so children and families aren't managing yet another unpredictable variable.
It's worth remembering
Help families build routines they can realistically maintain, not idealised schedules that collapse after three days. Check who sets rules, how they're communicated, and whether all adults around the child are on the same page.
Prioritise Co-Regulation Over Control
Contemporary models of ODD frame intense anger and defiance as emotion regulation problems as much as behaviour problems. Evidence-based programs such as Parent-Child Interaction Therapy (PCIT), Collaborative Problem Solving, and Coping Power explicitly teach adults to stay calm, validate feelings, and coach the child through problem-solving rather than escalating power struggles (Kaminski & Claussen, 2017). Parents in qualitative studies described feeling triggered by their child's aggression or defiance, and that their own emotional reactions, shouting, withdrawing, giving in, often made situations worse (Ljungström et al., 2020). Interventions that include parent emotion-regulation components, not just child behaviour plans, show better engagement and outcomes.
It's worth remembering
Your calm nervous system is part of the intervention. Support parents to slow down, recognise when they are getting flooded, and take short breaks before responding, especially during crises.
Use Evidence-Based Psychosocial Treatments as Your Map
Systematic reviews and evidence updates consistently highlight a core group of psychosocial interventions for ODD and related disruptive behaviour disorders (Kaminski & Claussen, 2017); (Waddell et al., 2018); (George & Laitano, 2023):
- Parent Management Training (PMT): coaching caregivers in consistent, positive parenting strategies.
- Parent-Child Interaction Therapy (PCIT): live coaching to build positive interactions and consistent discipline.
- Incredible Years and Triple P: group-based parent programs with strong evidence for reducing disruptive behaviour.
- Collaborative Problem Solving (CPS): emphasising skill-building and joint problem-solving over consequences.
- Coping Power and related child-focused CBT programs: targeting anger management, social skills and problem-solving.
Evidence base updates and systematic reviews have found that these programs, particularly those that are family-centred and skills-based, produce moderate to large reductions in disruptive behaviour and improvements in family functioning, including when children have co-occurring conditions (Kaminski & Claussen, 2017). Broader clinical literature reviewing counselling outcomes for youth with oppositional behaviour similarly suggests that psychotherapy is often effective at termination, though long-term maintenance of gains tends to depend heavily on ongoing family and system support. That ongoing, skills-based support in everyday settings is where our capacity building support fits in.
It's worth remembering
As an NDIS support worker you are not expected to deliver these programs, but you can align your day-to-day support with their principles: predictable routines, positive attention for cooperation, calm limit-setting, and collaborative problem-solving.
Engage Without Blame
Parents of children with disruptive behaviour consistently report feeling blamed, shamed and scrutinised by services, which makes engagement with support harder (Ljungström et al., 2020). In contrast, parents describe positive experiences as those where professionals were non-judgemental, took their emotional needs seriously, and understood behaviour in context, including trauma, loss and their own histories (Kaur et al., 2022).
It's worth remembering
Avoid language that implies the child or parent is at fault ("bad parenting," "manipulative child"). Speak in terms of stress, skills, and mismatches between demands and capacities. Normalising the difficulty of parenting a child with ODD is part of what makes support usable.
Families, Schools and Services Are Partners
Children with ODD move between home, school and community settings, and disruptive behaviour patterns are often maintained or reduced depending on how consistently adults respond across contexts. Reviews of prevention and treatment programs emphasise that the strongest outcomes occur when schools, families and services work from a shared understanding and use aligned strategies (Waddell et al., 2018). It's the same principle our community access support is built around: consistent people and consistent approaches across every setting a child moves through.
It's worth remembering
With the family's consent, coordinate with schools, therapists and other supports. Share what is working, and ask what is working elsewhere. Alignment reduces mixed messages for the child and lowers stress for everyone.
