Under the same roof: Parents’ COVID-related stress mediates the associations between household crowdedness and young children's problem behaviors during social distancing

During the COVID-19 pandemic, families worldwide are confined in their homes for an extended period of time due to social distancing. Conducted between April and July of 2021, the current study examined the impact of household crowdedness during school closure on parents’ COVID-related stress and young children's problem behaviors in Hong Kong, one of the world's most densely populated cities. Parents of 228 young children between 3- to 5-year-old reported their household living condition, parents’ COVID-related stress, and their children's externalizing and internalizing behaviors through an online survey. The result revealed that household crowdedness was predictive of parents’ COVID-related. Furthermore, parents’ COVID-related stress significantly mediated the associations between household crowdedness and children's internalizing and externalizing behaviors, controlling for family socioeconomic status. The study contributed to the growing research on the impact of the physical living environment as part of the ecological systems on family and child functioning. In time of crisis, young children rely on schools to support their development and wellbeing. The current findings caution the decision of school closure.
