Case formulation and Acceptance and Commitment Therapy (ACT) represent two powerful approaches in treating Obsessive-Compulsive Disorder (OCD). This guide explores the UCL approach to case formulation and how ACT complements traditional CBT for OCD treatment, drawing on research from University College London and NICE guidelines.
Understanding OCD
OCD affects approximately 1-2% of the population, according to the NHS. It involves:
- Obsessions: Intrusive, unwanted thoughts, images, or urges
- Compulsions: Repetitive behaviours or mental acts performed to reduce anxiety
Common OCD themes include contamination, checking, intrusive violent or sexual thoughts, and symmetry/ordering.
What is Case Formulation?
Case formulation is a collaborative process that helps therapist and client understand:
- How OCD developed and is maintained
- The specific triggers and maintaining factors
- Individual strengths and resources
- Targets for intervention
The UCL approach emphasises evidence-based formulation that integrates cognitive, behavioural, emotional, and environmental factors.
The UCL Case Formulation Approach
Key Components
- Presenting problems: Specific OCD symptoms and their severity
- Predisposing factors: Genetic vulnerability, early experiences, personality
- Precipitating factors: Events that triggered OCD onset
- Perpetuating factors: What keeps OCD going (compulsions, avoidance, beliefs)
- Protective factors: Strengths and resources
The Formulation Process
A collaborative, ongoing process that:
- Engages the client as an active participant
- Uses diagrams to make patterns visible
- Is revised as therapy progresses
- Guides treatment planning
Introduction to ACT for OCD
Acceptance and Commitment Therapy (ACT) offers a unique approach to OCD treatment, recommended by NICE as an evidence-based intervention.
Unlike traditional CBT which focuses on challenging thoughts, ACT helps clients:
- Accept intrusive thoughts without fighting them
- Reduce experiential avoidance
- Commit to valued life directions
- Develop psychological flexibility
The Six Core Processes of ACT
1. Acceptance
Learning to allow intrusive thoughts to exist without trying to control or eliminate them.
2. Cognitive Defusion
Changing the relationship with thoughts rather than their content. Thoughts are just thoughts, not facts or commands.
3. Present Moment Awareness
Mindfulness skills to stay grounded in the present rather than caught in OCD cycles.
4. Self-as-Context
Developing a sense of self that is separate from OCD thoughts and symptoms.
5. Values
Clarifying what matters most in life – what OCD is preventing the client from doing.
6. Committed Action
Taking steps toward valued living, even when OCD is present.
Integrating Case Formulation with ACT
The UCL approach combines detailed case formulation with ACT interventions:
- Formulation reveals the function of obsessions and compulsions
- ACT targets the experiential avoidance maintaining OCD
- Values work provides motivation for change
- Psychological flexibility reduces OCD’s impact
