NCT05691140

Brief Summary

The primary aim of this study is to evaluate whether a CBT group designed to target IU (CBT-IU) in pregnant women with heightened levels of IU, prevents postpartum anxiety. The investigators hypothesize that women with clinically significant IU during pregnancy will exhibit both significant reductions in IU, as well as a decrease in anxiety symptoms postpartum, compared to a treatment as usual control group. The secondary aim of this study is to evaluate whether CBT-IU significantly improves and/or prevents depression symptoms, worry symptom severity, and difficulties with emotion regulation. The investigators hypothesize that CBT-IU will lead to significant improvements in symptom severity compared to the treatment as usual control group.
