“…We developed a draft version of the FAB intervention content and worksheets to guide specific focus group topics. The core FAB intervention content is based on the same core components (CBT, Attachment Theory) and modular structure as MB ( Jensen et al, 2018 ; Le et al, 2015; McFarlane et al, 2017 ; D.

Tandon et al, 2018 ).…”
