The clinical effectiveness of guided self-help <i>versus</i> waiting-list control in the management of anxiety and depression: a randomized controlled trial

Abstract

The results demonstrate that this model of guided self-help did not provide additional benefit to patients on a waiting list for psychological therapy. The results are considered in the context of possible internal and external validity threats, and compared with previous trials of minimal interventions. The implications of the results for the design of future minimal interventions are considered.
