| Methods |
Design: three group parallel trial
Purpose: examine the effect of cognitive‐behaviour therapy on psycho‐social problems and seizure control in epileptic patients |
| Participants |
Patients: epileptic out‐patients with psycho‐social problems (anxiety, depression) and inadequate seizure control
Baseline comparability: yes |
| Interventions |
Placebo: sessions of supportive group counselling or discussion with no specific cognitive‐behaviour therapy
Untreated: no sessions
Experimental: sessions of behavioural‐cognitive therapy
(Co‐intervention:
‐'professional counselling or psychiatric treatment' to all but 6 patients
‐anticonvulsant medication. The difference in serum‐level between the groups was not significant.) |
| Outcomes |
Number of patients with improvement in seizure frequency (frequency diary)
Seizure rating by blinded observer
Global rating of psycho‐social adjustment |
