Scientific title
Cognitive behaviour therapy for epilepsy: improving seizure control and quality of life - a pilot randomised controlled trial
Acronym
Study hypothesis
This is a pilot/feasibility study investigating the use of cognitive behaviour therapy (CBT) plus standard medical care vs standard medical care alone in improving seizure control and quality of life in adults with refractory epilepsy. Specifically this feasibility study will enable us to:
1. Evaluate the applicability of our CBT techniques to a broader sample of patients than in our previous work
2. Determine the acceptability of this randomisation and treatment approach in a sample of patients attending specialist epilepsy clinics, thereby informing recruitment rates when designing a later, larger randomised controlled trial (RCT)
3. Obtain information on treatment effect sizes to undertake power calculations for a larger RCT

Condition
Epilepsy
Intervention
Following baseline recording of seizure frequency participants will be randomly assigned to one of two arms:
CBT (plus standard medical care):
CBT will comprise 12 weekly/fortnightly individual therapy sessions with the CBT therapist, over 4 months. Treatment will follow our prepared treatment manual, with homework tasks and seizure recordings reviewed at each session. In addition to seizure-specific interventions (e.g. development of countermeasures), more general cognitive behavioural therapeutic techniques will be employed to address the management of times of increased vulnerability to seizures and to improve patients overall physical and emotional well-being, with a view to relapse prevention. Handouts will be given to participants.
Standard medical care:
Participants will be seen by their epilepsy specialist in their regular clinic, depending on clinical need. As with the CBT group, we will monitor the number of appointments that participants have with their epilepsy specialist over the 4-month period and whether any medication changes are implemented during that time.
