The Indirect Effect of Parental Intolerance of Uncertainty on Perinatal Mental Health via Mindfulness During COVID-19

Abstract

Objectives The COVID-19 pandemic is associated with mental health difficulties, especially during pregnancy and early postpartum. Intolerance of uncertainty (IU) and reduced capacity for mindfulness—a protective factor for child-bearers—may be particularly relevant factors driving mental health problems given the unpredictable nature of the pandemic. The current study aims to shed light on modifiable paths to perinatal psychological distress by testing whether there is an indirect effect of IU on psychological symptoms through a perceived reduction in mindfulness during the pandemic. Methods Pregnant individuals (67%, n = 133) and new mothers within 6 months postpartum (33%, n = 66) participated in a cross-sectional online survey assessing IU, current and retrospective pre-pandemic mindfulness (FFMQ), and psychological symptoms (anxiety, depression, somatization; BSI). Perceived change in mindfulness was captured by including retrospective mindfulness as a covariate in the PROCESS macro used for analyses. Results Tests of the direct association between mindfulness, IU, and psychological symptoms showed significant effects of IU ( b = 0.46, SE = 0.064; p < .001) and perceived decrease in mindfulness during the pandemic ( b = − 0.72, SE = 0.08, p < .001) on psychological symptoms ( R 2 = .21–.34; F [2, 197] = 51.13–52.81, p < .001). The indirect effect of IU on symptoms via perceived decrease in mindfulness during the pandemic ( b = 0.13, SE = 0.043, 95%CI [.060, .226]) was significant ( R 2 = .41, F [3, 195] = 45.08, p < .001). Conclusions Results suggest that mothers who are less able to tolerate uncertainty experience more psychological symptoms, in part due to perceived reduction in mindfulness during the pandemic. Future research should examine whether IU is a screening risk marker and target for mindfulness-based interventions to improve maternal well-being and family outcomes.

The Psychological Impact of COVID-19 among Women Accessing Family Care Centers during Pregnancy and the Postnatal Period in Italy

“…The Brief Symptom Inventory-18 (BSI-18), omitting suicidality, was used to evaluate psychological distress in the last week, accordingly to previous pre-pandemic and pandemic studies involving pregnant women and new mothers [ 16 , 17 ]. The BSI-18 [ 18 ], which covers 18 of the 90 items in the SCL-90-R [ 19 ], is a self-report questionnaire including a summary scale of overall distress, the Global Severity Index (GSI), and three subscales: depression, anxiety and somatization.…”

Social and Cognitive Vulnerability to COVID-19-Related Stress in Pregnancy: A Case-Matched-Control Study of Antenatal Mental Health

“…Worry has also been associated with greater distress in pregnant women during COVID-19 15 . In addition to worry, individual differences in intolerance of uncertainty have been associated with mental health problems in pregnant women 16 . The continuously changing information regarding the effects of the virus on the health of women and their babies 17 may be particularly stressful for these women.…”
