Evaluation of the Effectiveness of Eye-tracking Assisted Attentional Bias Reduction Therapy on Reducing Symptoms of Post-traumatic Stress Disorder
Evaluation of the Effectiveness of Eye-tracking Assisted Attentional Bias Reduction Therapy on Reducing Symptoms of Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is associated with an attentional bias towards negative stimuli, which is supposed to contribute to the development and the maintenance of the disorder. We recently showed using eye-tracking evidenced two types of AB towards negative stimuli: a "physiological AB" found both in healthy and individual with PTSD, characterized by a stronger initial attentional engagement towards negative stimuli compared to neutral stimuli, as revealed by longer first fixation duration dwell time on negative pictures than on neutral pictures; a "pathological bias" observed only in individuals with PTSD and characterized by an heightened sustained attention towards negative stimuli once detected, which further increases with prolonged exposure. The present study aimed at assessing the effectiveness of an eye-tracking assisted attentional bias reduction therapy, targeting specifically the pathological bias on the reduction of PTSD symptoms
