| Summary: | 碩士 === 高雄醫學大學 === 心理學研究所 === 97 === Panic disorder has a higher prevalence rate among anxiety disorders. Threat-related processing bias has been considered a prominent role in etiology and maintenance of anxiety disorders, however, the result had inconsistent data. This study aimed to investigate the attentional bias for pictorial and word information in patients with panic disorder.
27 patients with panic disorder and 27 healthy adults were evaluated in this study. All subjects were asked to complete questionnaires including Anxiety Sensitivity Index, Beck’s Depressive Index 2nd Edition, and Trait Anxiety Index and to assess the dot probe task. The results showed none of the patients had attentional bias to either pictorial or word stimuli. There was no significant difference of bias scores between healthy adults and patients.
Time course with the first and second block was then added as another variable in the analysis. Our data showed that the patients revealed attentional bias for threatening pictorial stimuli in the first block rather than in the second block and had higher bias scores than healthy adults. Moreover, bias scores in pictorial stimuli could be predicted by anxiety sensitivity scores. Both scores could be moderated by depressive scores only in the first block.
Our study suggests that patients with panic disorder only reveal attentional bias for threatening pictorial stimuli in the first block. Attentional bias in patients with panic disorder will be attenuated over time and repetition of stimuli.
