The main premise of the process model of parenting by Jay Belsky (1984) is that parenting is determined by multiple factors of the parent, the child and sources of stress and support from the social context. It has been established that stressful circumstances such as armed conflicts can affect parenting, so it is interesting to examine the determinants of parenting in the context of the stress caused by the COVID-19 disease pandemic. The aim of this research was to examine the contributions of the characteristics of parents, children and family and wider contextual factors to the explanation of three dimensions of parenting - parental support, restrictive control and permissiveness measured by the URP-29 questionnaire (Keresteš et al., 2019). In order to measure parental contextual stressors, we constructed two questionnaires (Questionnaire of personal stressors related to the COVID-19 pandemic and Questionnaire of stressors related to the child) and their metric characteristics were examined. In total, 538 parents participated in the research (440 mothers and 98 fathers) who answered an online questionnaire posted on social networks. The obtained results show that each of the examined dimensions of parental behavior can be explained by one or more predictors from the groups of determinants of parental behavior according to Belsky's model. Greater parental support is predicted by the female gender of the parents, higher parental self-efficacy, younger age of the child and fewer number of children. Greater restrictive control is predicted by the younger age of the parents and their lower parental self-efficacy and greater externality, male gender of the child and unemployment. In the end, higher parental age and their greater parental externality and lower parental self-efficacy, a greater number of stressors related to the child's general difficulties, a fewer number of children and a smaller number of stressors related to the risks and difficulties caused by the COVID-19 disease pandemic are predicted to be more permissive. Parents' education and marital satisfaction did not contribute to explaining parental behavior. The results of this research suggest that the context of the pandemic may be related to parental behavior and that it is important to provide support to parents in order to ensure quality forms of parental behavior.
