Anxiety Disorders (ICD-10) Phobias – agoraphobia, social, specific Panic Disorder Generalised Anxiety Disorder GAD Obsessive Compulsive disorder OCD Post-Traumatic Stress Disorder PTSD Adjustment Disorders Conversion Disorders Somatoform Disorders

General principles People experience anxiety when they think situations are more dangerous than they really are Goals of treatment are to help person consider alternative, less frightening explanations Needs to be individualised, based on jointly derived alternative explanation (i.e. formulation)

Safety behaviours Behaviours which the patient engages in to try to avoid a feared outcome Safety Behaviours: –Increase self-consciousness/self-focus –Can increase feared symptoms (sweating, s etc –May draw unwanted attention to self –May contaminate the social situation –Increase the belief that they are effective –Prevent disconfirmation of this belief

Social Phobia (Clark & Wells) Social Situation Processing of self as social object Activates assumptions Perceived social danger Safety Behaviours Somatic & cognitive symptoms

Social Phobia: step by step (Clark) 1.Develop personalised model 2.Experiential learning exercise 3.Live feedback using audio/video 4.Attention training exercises 5.Interrogate the social environment using behavioural experiments 6.Deal with anticipatory anxiety & post mortem 7.Re-script early memories associated with mental imagery 8.Construct a more realistic social self-image 9.Tackle remaining assumptions

Model of OCD (Wells & Matthews, 1994) Trigger Activates meta-beliefs Appraisal of intrusion Beliefs about rituals Emotion Behavioural response

OCD: step by step (Salkovskis) Engage in assessment – make patient feel understood Reach shared understanding of problems through formulation Discuss alternative explanations Engage in treatment – help patient choose to change Help patient actively test alternative hypothesis and explore implications Generalise change Relapse prevention

Meta-beliefs Thoughts about the nature of intrusions Thought-Action Fusion (TAF) –Thoughts are as bad as actions –Thoughts of an event mean I have probably done it –If I think something, then I will do it Thoughts can cause events (Thought-Event Fusion) Attentional strategy consequences

Beliefs about Rituals Positive beliefs concerning neutralisation –Checking is the only way to feel better –If I don’t stop this feeling, I’ll go mad –If I complete _____ without thinking _____, everything will be OK Negative beliefs concerning neutralisation –I have no control over ______ –Rituals can damage my body

Targets for Treatment 1.Meta-beliefs –Via appraisal of intrusion –Is this my OCD or an important thought? –e.g. sparrows on the way to work….. 2.Beliefs about rituals 3.Behavioural responses –As a route to challenging 1 & 2.

Normalising Unacceptable intrusions are a normal occurrence (Rachman & Da Silva work in 1970s) –Problem lies in interpretation or appraisal of them Useful to worry about some things to some extent –Problem lies in belief that harm may arise if worries not controlled or counteracted in some way Some precautionary measures can be useful in some situations –Problem arises when person tries too hard (to get rid of thought, prevent harm, become certain, be clean etc) so……THE SOLUTION BECOMES THE PROBLEM…….

Behavioural Experiments How can we test the validity of this belief? If you changed (behaviour), what would be the outcome if (belief) was true? Describe in detail (time course, severity) the predicted outcome

Behavioural experiment record sheet SituationPredictionExperimentOutcomeWhat I learned Describe situation in detail What exactly did you think would happen? How would you know? Rate belief What did you do to test the prediction? What actually happened? Was your prediction correct? Balanced view Re-rate belief How likely is what you predicted to happen in the future?

Exposure & Response Prevention ERP Define belief to be tested Decide on exposure - ? graded hierarchy –May need to go beyond non-obsessional to anti-obsessional –Therapist modelling in early experiments –Maintain balance of responsibility with patient Identify typical/likely response to feared stimulus Rate anxiety/discomfort/fear before, during and after exposure Record outcome Repeat & review

Overcoming Resistance Pros and cons of existing behaviour vs new behaviour Guarantees…….. Goal setting to aid motivation Involve significant others Be aware of your own behaviour as a therapist – are you inadvertently facilitating the patient’s avoidance?

Relapse Prevention ‘Discharge’ = final big experiment ‘Setback’ vs relapse Utilise setbacks in course of therapy for learning Discuss the future and anticipate problems Keep long term goals in focus Therapy ‘blueprint’ and action plan Consider holding back one appointment for review after longer period
