In order to test the efficacy of a self-help anxiety management package, 62anxiety disorder patients were randomly allocated to one of three conditions.“Stress-pac” patients were given a self-help package,“Advice Only” patients were offered verbal advice onways of coping. Patients in both conditions were seen on one occasion shortlyafter referral for assessment and management advice. They were then placedback on the waiting list for a three-month period. Patients in the“No Intervention” condition also completed measuresduring this time. They were formally assessed at the end of this period. Allpatients were then followed through therapy. Results from a previous paperclearly indicated the superiority of the Stresspac condition at all data pointsup to one year follow-up. This paper looks at three-year follow-up and, whilefinding generally good outcome across conditions, finds further evidence ofthe superiority of the Stresspac condition on a range of measures.
