One hundred and nine patients with a primary diagnosis of GAD were allocated to either cognitive, behavioural, cognitive-behavioural or placebo versions of “Stress Control” large group didactic therapy or to a waiting list condition. Each group was run by two therapists and, with the exception of the placebo, contained between 20 and 24 patients. A wide range of measures were administered at pre-, mid- and post-therapy and at six month follow-up. At post-therapy, all therapy conditions showed highly significant change on almost all measures, with the active therapies, and to a slightly lesser degree, the placebo, being significantly different to the waiting list on most measures. At follow-up, the active treatment conditions enhanced post-therapy improvements, while the placebo condition maintained progress. No significant differences existed between the four treatment conditions at post-therapy and, with the exception of one measure, at follow-up. However, a trend at both points favours the cognitive and behavioural conditions.
