Objective: Families in the United States experienced tremendous disruptions during the COVID-19 pandemic. This study evaluated the relationship of parental stress during the pandemic with interruptions in availability of services (childcare, after-school activities, and medical appointments) for children. Methods: We analyzed data from 2 waves of the Measuring the Impact of Violence Against Children and Women During a Pandemic survey to develop a multivariable logistic regression model of the association between caregivers' stress and pandemic-related disruptions in children's lives. Caregivers' past experiences of childhood abuse, recommended stress-relieving activities, and responses to the statement “helping my child(ren) with their education, including remote schoolwork, has been very stressful and/or has resulted in increased tension at home” were included as covariates. Demographic and socioeconomic variables were examined as potential confounders. Results: In total, 3479 (73.3%) of 4659 respondents reported feeling stressed since the start of the pandemic. For every one-item increase in the number of COVID disruptions in children's lives, the odds of feeling stressed increased by 20% (OR 1.20: p value < 0.0001, 95% confidence interval [CI], 1.14–1.27). Compared with men, women had 60% higher odds of feeling stressed (odds ratio [OR] 1.60: p value < 0.0001, 95% CI, 1.32–1.93). The covariates listed earlier were all statistically significant. Conclusion: Pandemic-related disruptions in children's lives were significantly associated with caregiver stress. Women were more likely to feel stressed than men. Sex, education, marital status, and family income were also associated with parental stress. These results suggest that childcare continuity and parental support should be part of disaster planning.
