Objectives: Despite the well-documented negative effects of posttraumatic stress symptoms following childbirth (PTSS-FC), research on protective factors for PTSS-FC is still missing. Aiming to fill this gap, we proposed and examined a process model through which maternal-infant skin-to-skin contact after birth reduces PTSS-FC by decreasing negative emotions, especially for women who had operative births.Method: In this longitudinal study, pregnant women (N = 1833) were recruited at community and hospital medical centres in the center of Israel and through internet forums.
