Since the onset of the COVID-19 pandemic, many parents have felt anxious, overwhelmed, and stressed out due to the changes in education and family and working routines. This work aimed to describe three dimensions of perceived parenting in the COVID-19 pandemic context, describe possible changes perceived by mothers in their children’s behavior during the social isolation phase, analyze if behavioral changes vary according to the dimension of perceived parenting, and analyze whether the characteristics of perceived parenting dimensions vary with mother’s (...) age, number of children and number of work hours. The purposive sample consisted of 646 mothers of school-aged children in Argentina. Questionnaires on sociodemographic and work-related data, and on children’s behavior were administered, as well as an instrument that assessed the three parenting dimensions. The sociodemographic and work-related variables of the study were described using descriptive statistics: measures of central tendency, frequencies, and percentages. The changes perceived in children’s behavior according to the reports given by the mothers regarding positive parenting, parenting stress, and school support were compared using the Mann Whitney’s U test, respecting the qualitative nature of the evaluated indicators. A factorial MANOVA was conducted to analyze the effect of mother’s age, ä number of children, and the number of work hours on parenting perceived by mothers. Parenting dimensions influenced the perceived children’s behavior. Mothers with higher positive parenting perceived more changes in their children’s behavior. In addition, those mothers who were more stressed out perceived more problems in almost all the measured behaviors than less stressed mothers. The mothers who reported to have provided more school support to their children perceived that they adapted better to online classes. Finally, mothers’ age and the number of children I parenting, particularly on parenting stress and school support, whereas work hours did not. A number of children affected stress and school support, and age only affected parenting stress. The only significant interaction regarding parenting was observed between the number of children and the number of work hours, which specifically affected parenting stress. Although social isolation due to COVID-19 affected children’s behavior, according to mothers, this might be partially linked to the number of children, mothers’ age, and the mothers’ parenting style. These initial findings may allow the identification of some protective factors and some risk factors of parenting in the Argentine context of a pandemic, and the design of preventive psychoeducational interventions to optimize the psychological wellbeing of families.
