Physical activity moderates the association between parenting stress and quality of life in working mothers during the COVID-19 pandemic

STATEMENT OF PROBLEM: Working mothers are a population experiencing heightened levels of parenting stress during the COVID-19 pandemic. The purpose of the current study was to evaluate the associations between parenting stress, quality of life, and physical activity in a national sample of working mothers who endorsed having been forced to work from home full-time due to the COVID-19 pandemic and examine if physical activity moderates the association between parenting stress and quality of life in this sample of working mothers. METHODS: Participants in this cross-sectional study were 200 full-time working mothers from the United States (mean age = 33.50 years; SD = 6.25; 70.0% White). Participants were recruited from a Qualtrics research panel and completed the International Physical Activity Questionnaire Short-Form, the World Health Organization Quality of Life Scale-Brief Version, the Parental Stress Scale, and a demographic questionnaire. RESULTS: After controlling for socio-demographic variables (i.e., maternal marital status, annual income, maternal highest level of education), greater parenting stress was associated with poorer maternal quality of life across domains (standardized beta coefficients ranged from −0.26 to −0.47; p < .001). The interaction between parenting stress and moderate intensity physical activity was associated with social relationships quality of life and environment quality of life (standardized beta coefficients ranged from 0.15 to 0.17; p < .05) in our sample of working mothers. The negative effect of parenting stress on maternal social relationships and environmental quality of life was weaker for working mothers who engaged in higher levels of moderate intensity physical activity. CONCLUSIONS: Our findings suggest that moderate intensity physical activity may attenuate the negative impact of parenting stress on social relationships and satisfaction with one's environment in working mothers during the COVID-19 pandemic.
