Background: Moderate to severe anxiety disorders such as obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), social phobia and panic disorder are common, and affect approximately 11-16% of women in pregnancy. Psychological treatments for anxiety disorders, primarily cognitive behaviour therapy (CBT), have a substantial evidence base and recently time-intensive versions have been found as effective as weekly treatments. However, this has not been trialled in women who are pregnant, where a shorter intervention may be desirable.
Methods: The ADEPT study is a feasibility randomised controlled trial with two parallel intervention groups. Time-intensive one-to-one CBT and standard weekly one-to-one CBT delivered during pregnancy will be compared. Feasibility outcomes including participation and follow-up rates will be assessed, alongside the acceptability of the interventions using qualitative methods.
Discussion: The study will provide preliminary data to inform the design of a full-scale randomised controlled trial of a time-intensive intervention for anxiety during pregnancy. This will include information on the acceptability of time-intensive interventions for pregnant women with anxiety disorders.
