About

Behavioural activation (BA) is widely accepted as an efficacious treatment for depression. It has been suggested that several depression treatments work via early changes in emotional processing (e.g. affective bias in the processing of facial expressions) and that these could help predict treatment success, but it has not yet been examined whether the same applies in behavioural interventions. The investigators will examine how BA affects early emotional information processing in participants who are currently experiencing low mood, to see whether this can predict eventual changes in mood and to gain a better understanding of the treatment mechanisms of BA. Participants will be in three groups undergoing either behavioural activation, or activity monitoring alone (active control) for 4 weeks, or they will be on a waiting list (passive control). The investigators will also examine whether other factors, such as anxiety, social support and environmental reward, can predict the success of BA. This could help us understand how BA works and who may be most suitable for this intervention.
