Today Dr Simon E. Blackwell ended his 10-day study visit at our research lab by giving a much appreciated seminar. Here is the interesting abstract:
Depression is a major global health problem, and treatment innovation is required. “Cognitive Bias Modification” (CBM) paradigms offer the potential for novel treatment development via cognitive science. CBM aims to directly “re-train” cognitive biases via computer programs, rather than face-to-face therapy. We have developed a CBM paradigm, imagery CBM, which targets the deficit in positive future imagery observed in depression.
In this talk I will present the imagery CBM paradigm, and describe the process of its development from initial laboratory experiments with healthy volunteers (e.g. Holmes, Lang, & Shah, 2009), to a randomized controlled trial (RCT) currently in progress, via studies with analogue samples (Pictet, Coughtrey, Mathews, & Holmes, 2011), single case series (Blackwell & Holmes, 2010), and small initial clinical studies (Lang, Blackwell, Harmer, Davison, & Holmes, 2012). I will present recent work into understanding the basic mechanisms underlying the training (Clarke, Nanthakumar, Notebaert, Holmes, Blackwell, & MacLeod, in press), and combining imagery CBM with internet cognitive behaviour therapy (Williams, Blackwell, Mackenzie, Holmes, & Andrews, in press).
Finally, I will discuss a current ongoing RCT testing the efficacy of imagery CBM in depression when delivered via the internet, and how it forms part of a clinical translational process to develop novel cognitive interventions for depression, via an interweave of basic and translational research.
