Lockdowns put in place in response to the COVID-19 health crisis have changed daily functioning for families and potentially the emotional experience of individuals in their parenting role. Our study aimed to highlight the importance of the environmental consequences associated with lockdowns on parental burnout. We compared data on parental burnout levels from two French samples: the first collected in 2018 (N = 1332) and the second collected during the last month of lockdown (N = 522). Our results show that parents included during the lockdown period reported significantly, but slightly, higher saturation (a dimension of the parental burnout construct) than parents included 2 years earlier. However, the number of children per age group, maintaining employment, and having to provide schooling at home are not variables that explain differences in the level of parental burnout between our two samples. Our results are discussed with regard to the risk factors identified and the French context.
