Low Estradiol May Not Impede Cognitive Restructuring in Women With Anxiety Disorders.

Prior research suggests that estradiol may moderate fear extinction in animal models and humans. Based on these findings, estradiol may also moderate cognitive reappraisal, which is theorized to be an important mechanism of change in extinction-based therapy (exposure therapy). We compared cognitive restructuring (CR) skills acquisition and outcome between women with primary anxiety disorders who had high versus low estradiol using a standardized CR task that closely resembles clinical practice. As a proxy of CR outcome, we assessed subjective distress ratings before and after the task and psychophysiological arousal (heart rate and electrodermal activity) throughout the task. Contrary to predictions, results showed that CR skills acquisition and outcome did not differ between the high and low estradiol groups. Although both groups demonstrated reductions in negative affect and skin conductance responses during the CR task, suggesting that participants were able to acquire CR skills and use them effectively to regulate distress, the groups did not differ with respect to CR ability or outcome. The findings suggest that estradiol may not moderate cognitive reappraisal, and may have more of an effect on basic habituation and extinction processes instead.
