How effective are psychological therapies, such as CBT, psychodynamic therapy and supportive therapy, compared with treatment as usual/waiting list (TAU/WL) and compared to one another, for patients with GAD?
Patients who attend for group CBT and older patients are more likely to drop out of therapy. None of the studies looked at the long-term effectiveness of CBT (the mean length of trial was 8 months), or reported on the possible side-effects or acceptability of psychological therapies.
GAD is a common disorder, characterised by excessive worry or anxiety about everyday events and problems. It is estimated to have a lifetime prevalence of 5.1% with a 12 month prevalence measurement of 3.1%.
