Imagery rescripting versus in vivo exposure in the treatment of snake fear

This study compared imagery rescripting, in vivo exposure therapy and their combination in the treatment of snake fear. Imaginal ability was assessed pre-treatment, and was correlated with baseline avoidance. Snake fearful individuals were randomly assigned to cognitive therapy involving imagery rescripting, in vivo exposure, a combination of the two, or a relaxation control. All active treatment groups improved significantly more than the control group in both fearfulness and behavioral approach. There were no significant differences between the active treatment groups, although the combined treatment tended to be slightly more efficacious.
