Psychological treatment of depression: a review

The available empirical evidence on the efficacy of psychological intervention in depressive disorders is reviewed. No fully adequate study has yet appeared; but there seems sufficient consensus to justify the conclusion that psychological treatment can be effective in alleviating current depressive states and that more complex therapies involving both behavioural and cognitive elements appear the most promising. However, it remains to be seen whether the success of these techniques depends upon the type of depressive disorder manifested; and whether they are applicable across a full range of verbal reasoning ability and socio-economic class.
