Study Arms:
- Sertraline (Type: ACTIVE_COMPARATOR): The pharmacological arm of the trial is the Selective Serotonin Reuptake Inhibitor (SSRI) Sertraline, prescribed at a daily dose of between 25 and 150mg by the patient's general practitioner (GP). If the medication is well tolerated and associated with reported clinical improvement we are asking the patients in this arm to continue taking it for 12 months.
- Cognitive Behavioural Therapy (CBT) (Type: ACTIVE_COMPARATOR): The psychological therapy arm of the trial is Cognitive Behavioural Therapy (CBT) delivered by high intensity psychological therapists from local IAPT services. They will provide 14 to 16 sessions of a manualised treatment developed specifically for use in GAD and will be trained in its delivery.

Based on this trial design, predict the completion outcome and termination type (if applicable).
