简要总结
The purpose of this trial is to study how teens with and without an anxiety disorder make decisions.
This is a brain imaging study using functional magnetic resonance imaging (fMRI) in adolescents between the ages of 13 and 17.
详细描述
Preliminary analyses of behavioral data showed no group differences in response times during the decision-making games. However, behavioral ratings of certainty during the task showed differences between groups. Anxiety-disordered participants indicated lower levels of certainty during the most uncertain conditions of the task (p < .05). This difference was consistent with the study hypothesis. Within-subjects analyses of the decision-making tasks showed that subjects responded as expected. Reaction times (RT) during uncertain conditions of the HiLo-Game were significantly longer than during more certain conditions (p = .001). Diary Task RTs for rating ambiguous situations were significantly longer than ratings of unambiguous situations (p = .019). Preliminary Analyses showed a significant correlation between Intolerance of Uncertainty (IU) and RT during the Marble Task (r = -0.54, p < .05). Preliminary analysis also showed significant correlation between ratings of level of anxiety during the diary task and IU, IS, MASC and the child version of the SCARED. These preliminary results were not submitted for publication.
