Group Rumination-focused Cognitive-Behavioral Therapy versus traditional Group Cognitive-Behavioral Therapy for Major Depression: a randomised controlled trial
The objective of this PhD project is to contribute to the development of evidence-based psychotherapy for depression. It does so by comparing the efficacy of Rumination-focused cognitive behaviour therapy (RFCBT) with standard cognitive behaviour therapy (CBT) for depression. Furthermore, the thesis also aims to investigate the association between depressive rumination and attentional processes in depression. The thesis consists of three papers and a frame. Paper 1 is a study protocol for a randomised clinical trial (RCT) comparing the efficacy of RFCBT with that of (CBT) for depression. Paper 2 presents the results from the randomized control trial described in paper 1. Paper 3 investigates the relationship between depressive rumination and attentional processes in patients suffering from depression. The RCT study (N = 131) described in paper 1 and paper 2 found group based Rumination-focused CBT to be superior to group standard CBT in reducing symptoms of depression for patients treated in a psychiatric outpatient clinic. The experimental study described in paper 3 found no association between depressive rumination and emotional bias in selective attention. Clinical and theoretical implications of these findings will be discussed at the public defence.
