Research summary
Generalised anxiety disorder (GAD) is a highly prevalent and severe psychiatric condition. Cognitive theories and information processing models of anxiety posit that negative biases in interpretation represent one mechanism that helps develop and maintain symptoms of GAD. Cognitive Bias Modification (CBM-I) training is a computer text based paradigm that has proven successful in decreasing negative interpretation biases and, most importantly, reducing levels of anxiety. The majority of research thus far has used non-clinical samples. The present study proposes to extend such research using patients presenting with clinical levels of GAD (n =9) adopting a multiple baseline single case series design. Participants will be randomised to length of baseline assessment period (1 – 3 weeks) and subsequently complete daily sessions of CBM-I at home for 1 week; measures will be repeated and follow up assessment completed. At the end of the study, participants will take part in semi-structured interviews to explore their beliefs surrounding CBM-I as part of a separate qualitative piece of research. It is predicted that CBM-I will modify interpretation biases to a more benign or positive level and reduce levels of anxiety both post-treatment and at 1- week follow up. The proposed study represents early stages of clinical testing to assess the effectiveness of CBM-I as a therapeutic tool for patients experiencing clinical levels of GAD.
