Infant neurodevelopment during the COVID-19 pandemic: Associations with maternal pandemic-related experiences, parenting stress, and self-efficacy.

BACKGROUND: Although pandemic-related experiences have been linked to the psychological well-being of mothers, the effects of the COVID-19 pandemic on infant neurodevelopmental outcomes have not been sufficiently studied.

AIMS: To assess whether maternal COVID-19-related experiences (i.e., COVID-19-related health, risk, resource worries, and feelings of grief), parenting stress, and maternal self-efficacy are associated with infant neurodevelopment as measured by the Ages and Stages Questionnaire, Third Edition (ASQ-3) maternal report when infants were between 8 to 10 months of age. Furthermore, this study examined the moderating effect of maternal self-efficacy between maternal COVID-19-related experiences and infant neurodevelopment.

METHODS: This cross-sectional study included 122 women who were drawn from the Perinatal Experiences and COVID-19 Effects (PEACE) Study, with online surveys administered between November 2020 and August 2022.

RESULTS: After controlling for maternal anxiety and depression symptoms and demographic factors, hierarchical regression analysis indicated that parenting stress showed no effect on ASQ-3 scores. However, more adverse COVID-19-related experiences and higher levels of maternal self-efficacy were associated with better infant neurodevelopment. Moreover, there was a significant interaction effect between maternal self-efficacy and COVID-19-related experiences on infant neurodevelopment. For mothers with moderate to high levels of self-efficacy, more adverse COVID-19-related experiences were associated with better infant neurodevelopment. For mothers with low levels of self-efficacy, more adverse COVID-19-related experiences were associated with poorer developmental outcomes in infants.

CONCLUSIONS: Under adverse conditions, confidence in caregiving may afford more optimal infant neurodevelopment. Interventions aimed at fostering maternal self-efficacy and addressing specific stressors can be valuable in promoting positive developmental trajectories for infants born during the pandemic.
