This study developed a video intervention using natural images for the anxiety clinical sample group, and it examined its effectiveness, focusing on psychophysiological indicators. After selecting the anxiety clinical sample group, it assigned them into an experimental group(n=15) and a control group(n=15). In the experimental group, it conducted 12 sessions of video programs using natural images. Before and after the program and even at a follow up time, it measured anxiety(General Anxiety Disorder, Trait and State Anxiety), mental well-being, positive affect, negative affect, and baseline EEG. As a result, this study cannot identify significance of its interaction effect between time interval and conditions from every variable. However, anxiety decreased after intervention than before, and it did not increase at follow-up than after, only in the experimental group. In addition, negative affect in the experimental group significantly decreased before and after the intervention. In the experimental group, participants showed decreased beta, high beta and alpha waves while gamma and theta waves increased compared to the control group. Accordingly, this study suggested that the video program can be used as relaxation method to help control anxiety and negative affect.
