 The purpose of this pilot study is to explore whether there is a differential impact of verbal versus imagery-based cognitive behavioural therapy CBT as a treatment augmentation strategy for individuals with social anxiety disorder SAD. Clients who have not demonstrated clinically significant change following group CBT for SAD will receive four additional sessions of either verbal-based CBT or imagery-based CBT. We hypothesize that that individuals who receive imagery-based CBT will experience even stronger improvements and be more satisfied with their treatment than individuals who received traditional verbal-linguistic CBT.
