The objectives of the present longitudinal study were to (i) understand the potential impacts of concern about the COVID-19 epidemic and containment measures (e.g. lockdown) on the psychological and emotional status of women during pregnancy and after childbirth, (ii) identify factors associated with these impacts, and (iii) to study the mothers’ coping strategies and protective factors.

Data were collected during pregnancy (timepoint 1, during France's first period of lockdown from April 6th to May 11th, 2020) and then one month after childbirth (timepoint 2). At timepoint 1, 90 women completed a sociodemographic questionnaire, the Spielberger Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, and the Multidimensional Scale of Perceived Social Support. At timepoint 2, 26 women completed the City Birth Trauma Scale, the Interpersonal Emotional Regulation Questionnaire, and the Posttraumatic Growth Inventory. The relationship between social support and worry about the fetus/baby during the COVID-19 pandemic was statistically significant (Rho=- 0.21; p<0.05). Worry about the fetus/baby was also significantly correlated with the anxiety score (Rho=0.60; p<0.01) and the depression score (Rho= 0.37, p<0.01). When the study population was compared with a control sample of new mothers having given birth outside the lockdown period, we observed differences in the prevalence of anxiety but not in the prevalence of postpartum PTSD. Lastly, the relationship between posttraumatic growth and emotion regulation was not significant (Rho=0.29, p = 0.16 for soothing; Rho=0.26, p = 0.20 for social modeling; Rho=0.28; p = 0.17 for perspective-taking; Rho=0.35; p = 0.08 for enhancing positive affect). In view of the sample size and the statistical tests, this study should be considered as exploratory. Our present results open up opportunities for further research and suggest that a possible impact of COVID-19 must be considered when evaluating potential psychological disorders in the perinatal period.
