Abstract Details

2020, Master of Science (MS), Ohio University, Clinical Psychology (Arts and Sciences).
Research suggests that anxiety can be conceptualized as a two-dimensional construct comprising anxious apprehension (worry, negative expectations, fears, and rumination about the future) and anxious arousal (hyperarousal related to current events, accompanied by panic-like symptoms such as heart pounding, dizziness, shortness of breath, and sweating). A potential biomarker of these dimensions of anxiety is asymmetrical brain activity based on the alpha EEG band. Prior research shows that anxious apprehension is associated with left frontal asymmetry and anxious arousal is associated with right frontal asymmetry. However, there are limitations of prior studies such as using an extreme group approach, conflating state and trait variability, and using a cross-sectional design. In the present study, ecological momentary assessment (EMA) was used to separate state and trait variability of anxious apprehension and anxious arousal in community members and graduate students. Contrary to prediction, there were no significant relations between baseline frontal asymmetry with baseline or EMA-collected trait anxious apprehension and anxious arousal, controlling for state levels of these constructs. However, baseline depression, a control variable in this study, was associated with RFA. Findings suggest that frontal asymmetry may be a more robust indicator of depression than of anxious apprehension or anxious arousal during the resting state task. Future research is needed to test the association of asymmetry with anxious apprehension and anxious arousal during experimental manipulation of anxious apprehension and anxious arousal.
