OCD in Childhood and Adolescence

Vocabulary flashcards covering the diagnostic criteria, developmental differences, cognitive theories, and treatment strategies for pediatric Obsessive-Compulsive Disorder.

Obsessions

Intrusive, unwanted, and persistent thoughts, images, or urges that lead to marked distress, anxiety, or disgust.

Compulsions

Repetitive behaviors or mental acts performed in response to an affect stimulated by an obsession or rigid rules, intended to reduce distress or prevent a dreaded situation, though they are often not connected realistically.

NJRE

Refers to "Not Just Right Experiences," which are feelings that prompt compulsions like tapping, touching, or arranging until a subjective sense of completeness is achieved.

Hoarding Disorder

An obsessive-compulsive related disorder defined as the excessive acquisition and inability to discard possessions of little value.

Insight

The degree to which an individual believes their OCD beliefs are true, ranging from good/fair insight to poor insight, or absent/delusional beliefs.

Family Accommodation

Behaviors by family members that facilitate rituals, support avoidance of triggers, provide reassurance, or modify family routines to meet the child's OCD demands.

Bimodal Age of Onset

The two peak periods for the onset of OCD: late childhood/early adolescence ($7.5-12.5$ years) and young adulthood (approximately $21$ years).

Thought-Action Fusion (TAF)

A cognitive theory where an individual believes that having a thought is as bad as performing the action or that it increases the likelihood of the event occurring.

Moral TAF

The belief that having an intrusive thought (e.g., about swearing in church) is morally equivalent to actually performing the act.

Likelihood TAF

The belief that thinking about a negative event (e.g., falling ill) makes it more likely that the event will actually happen.

Inflated Responsibility for Harm

The belief that one has pivotal power to bring about or prevent subjectively crucial negative outcomes.

Egodystonic

Thoughts or behaviors that are inconsistent with an individual's self-image or values, characteristic of OCD obsessions.

Egosyntonic

Thoughts or behaviors that are congruent with an individual's state of mind or self-image, often seen in depressive ruminations.

Rumination

Negative, repetitive, and persistent thoughts about negative events or past courses of action that are congruent with the person's state of mind.

Differential Reinforcement of Other Behaviors (RDO)

A behavioral strategy that involves teaching parents to identify and reinforce alternative or incompatible behaviours, rather than the compulsive symptoms associated with OCD. This approach aims to decrease the frequency of OCD behaviours by promoting positive actions that serve as healthier replacements. It can include rewarding a child for engaging in activities that do not trigger OCD symptoms or reinforcing their ability to tolerate anxiety without resorting to compulsions. RDO emphasizes the importance of consistently providing reinforcement to strengthen the desired behaviours, creating an environment that supports the child's progress towards managing their OCD.

Exposure and Response Prevention (ERP)

A treatment method involving exposing the patient to anxiety-generating situations while preventing the performance of rituals or avoidance behaviors.

Habituation

The process by which anxiety naturally decreases over time when an individual remains in contact with a feared stimulus without performing a compulsion.

The Thermometer

A communication tool used in therapy to help children identify and graduate their level of anxiety or discomfort during an exposure task.

The Battlefield

A metaphor used in psychoeducation to identify locations or situations (the Transition Zone) where OCD symptoms occur and where treatment tasks will take place.

Trichotillomania (TTM)

A related disorder involving repetitive hair-pulling, which shows increased prevalence in OCD cases that involve tics.

Reading OCD in Children and Adolescents

Front:
What are the key features, assessment issues, and treatments for OCD in children and adolescents?

Back:

Key Points

• OCD involves obsessions (intrusive thoughts) and compulsions (repetitive behaviours) that are distressing and time-consuming.

• Early identification is important because OCD can become chronic and impairing if untreated.

• In young people, OCD can be hard to recognise because it may look like normal childhood routines or rituals.

Assessment & Differential Diagnosis

• Careful assessment is needed to distinguish OCD from normal developmental behaviour.

• OCD can overlap with:

  • Autism Spectrum Disorder (rigid routines)

  • Tic disorders (repetitive movements/vocalisations)

  • Psychosis (unusual beliefs, but different underlying mechanisms)

Treatment

• CBT with Exposure and Response Prevention (ERP) is the main evidence-based treatment.

• ERP involves gradual exposure to fears while preventing compulsive behaviours.

• Medication (e.g. SSRIs) may be used in more severe cases or alongside therapy.

Evaluation

• Early treatment leads to significantly better outcomes.

• Misdiagnosis is possible due to overlap with other developmental conditions.

Reading Family-Based Treatment for Paediatric OCD

Key Points

• Family involvement is important in treating OCD in children and adolescents.

• Family members may unintentionally maintain OCD symptoms through family accommodation.

• Family accommodation includes helping with compulsions, reassurance, or avoiding triggers.

• Reducing accommodation is an important treatment target.

Treatment Approach

• CBT with Exposure and Response Prevention (ERP) remains the core evidence-based treatment.

• Family-based CBT includes educating parents and reducing reinforcing behaviours.

• Addressing family factors improves treatment effectiveness.

Key Research Findings (McGrath & Abbott, 2019)

• Family-based psychological treatments improve OCD symptoms in young people.

• They also reduce family accommodation behaviours.

• Greater improvement occurs when more family factors are directly targeted in treatment.

Evaluation

• Strong evidence that family involvement improves outcomes in paediatric OCD.

• Highlights that OCD is maintained within a family system, not just the individual.

• Treatment can be more effective when parents are actively included rather than excluded.

Why is OCD in children difficult to diagnose and what conditions does it overlap with?

Key Points

• OCD symptoms can resemble behaviours seen in other neurodevelopmental and psychiatric disorders.

• Key challenge is distinguishing compulsions from repetitive behaviours in other conditions.

• Accurate diagnosis is essential because treatments differ across conditions.

Key Studies Krebs & Heyman (2015)

• Highlighted overlap between OCD and autism-related rigid routines and restricted behaviours.

• Noted that children often present with poor insight, complicating diagnosis.

• Emphasised need for structured clinical assessment tools.

Mataix-Cols et al. (2005)

• Found significant comorbidity between OCD and tic disorders (e.g. Tourette’s).

• Suggested shared neural circuitry involving habit formation and motor control.

• Reported that tic-related OCD may present differently clinically (more sensory-driven compulsions).

Gillan et al. (2011)

• Used experimental tasks to show overlap between OCD and habit learning systems.

• Found OCD patients show impaired goal-directed control and increased habitual responding.

• Suggested compulsivity may reflect shared cognitive mechanisms across disorders.

Evaluation

• High comorbidity complicates diagnosis and treatment planning.

• However, cognitive and neurobiological research supports overlapping mechanisms.

• Structured assessment improves diagnostic accuracy but is time-consuming.

CBT with Exposure and Response Prevention (ERP)

Key Points

• ERP is the first-line psychological treatment for OCD.

• Exposure involves confronting feared thoughts/situations without avoidance.

• Response prevention blocks compulsive behaviours that maintain anxiety reduction.

• Treatment works by breaking the obsession–compulsion reinforcement cycle.

Key Studies Abramowitz (2006)

• Reviewed CBT mechanisms and outcomes in OCD.

• Found ERP produces large effect sizes in symptom reduction.

• Identified exposure as the key active ingredient in CBT for OCD.

Öst et al. (2015)

• Meta-analysis of psychological treatments for OCD.

• Found ERP-based CBT significantly outperformed non-exposure therapies.

• Reported durable improvements post-treatment compared to alternative approaches.

Foa et al. (2005)

• Compared CBT (ERP) with medication (clomipramine/SSRIs).

• Found CBT produced greater long-term symptom reduction than medication alone.

• Showed relapse rates were lower in CBT group at follow-up.

Evaluation

• Strongest evidence base of all OCD interventions.

• Highly effective and recommended in clinical guidelines.

• However, exposure can be highly distressing and may lead to dropout.

Family Accommodation in Paediatric OCD

Key Points

• Family accommodation refers to family members participating in or enabling OCD behaviours.

• Includes reassurance giving, assisting compulsions, or modifying routines.

• Accommodation reduces short-term distress but maintains OCD long-term.

• Reducing accommodation is a key treatment target in paediatric OCD.

Key Studies McGrath & Abbott (2019)

• Meta-analysis of family-based interventions in paediatric OCD.

• Found reductions in OCD severity when family factors were directly targeted.

• Showed that reducing accommodation improves treatment outcomes significantly.

Peris et al. (2008)

• Found strong correlation between family accommodation and OCD severity in children.

• High accommodation predicted poorer treatment response.

• Suggested accommodation reinforces compulsive behaviour through negative reinforcement.

Storch et al. (2007)

• Found family accommodation was associated with increased symptom severity and impairment.

• Identified accommodation as a predictor of poorer CBT outcomes.

• Highlighted bidirectional relationship between child symptoms and parental behaviour.

Evaluation

• Strong evidence that OCD is maintained within family systems.

• Family involvement improves treatment outcomes when properly targeted.

• However, changing entrenched family behaviours can be difficult and stressful.

Pharmacological and Combined Treatments for Paediatric OCD

Key Points

• CBT with ERP is first-line treatment.

• SSRIs (e.g. fluoxetine, sertraline) are used for moderate to severe cases.

• Combined treatment may be used in more severe or treatment-resistant OCD.

• Early intervention improves prognosis and reduces chronicity.

Key Studies Krebs & Heyman (2015)

• Recommended CBT with ERP as first-line treatment in children.

• Highlighted importance of early intervention in improving outcomes.

• Noted medication may be used when CBT is insufficient.

Geller et al. (2003)

• Found SSRIs significantly reduce OCD symptoms in children and adolescents.

• Reported moderate effect sizes compared to placebo.

• Noted relapse can occur when medication is discontinued.

Pediatric OCD Treatment Study (POTS) Team (2004)

• Compared CBT, SSRIs, combined treatment, and placebo.

• Found combined CBT + medication most effective for severe OCD.

• CBT alone was nearly as effective as combined treatment and superior to medication alone.

Evaluation

• CBT remains most effective long-term treatment.

• Medication is useful but often less durable alone.

• Combined treatment is beneficial for severe or complex presentations.
