From prematurity to parenting stress : the mediating role of perinatal post-traumatic stress disorder

Preterm delivery may lead to the emergence of symptoms of Post-Traumatic Stress disorder (PTSD), which may, in turn, affect the quality of the mother-child relationship. The aim of this study is to shed light on the development of parenting stress in mothers of preterm and full-term children. It is hypothesized that PTSD symptoms mediate the relationship between preterm/full-term birth and the levels of parenting stress. Perinatal PTSD, parenting stress and social support were assessed in 156 mothers of full-term children and 87 mothers of preterm children. Mothers of preterm children experienced more post-traumatic stress and parenting stress than mothers of full-term children. However, the relationship between preterm delivery and subsequent levels of parenting stress was mediated by PTSD symptoms. These findings suggest that the maternal perception of childbirth as a traumatic experience and the subsequent development of PTSD symptoms are pivotal in the emergence of parenting stress
