The main goal of the research was to explore the connection between the consequences of the COVID-19 pandemic and the daily life of mothers of elementary school children. Self-assessment of deterioration in mothers' daily life due to the COVID-19 pandemic was predicted based on socio-demographic data, concerns about the COVID-19 pandemic, marital/relationship satisfaction, and perceived social support from family, friends, and significant others. Additionally, the life events of mothers of elementary school children related to the COVID-19 pandemic were examined. The data were collected as part of the project of Croatian Science Foundation Child welfare in the context of the family (CHILD-WELL). A total of 1,206 mothers of elementary school children from Varaždin and Osijek-Baranja counties participated in the research. The average age of the participants is 41.14 years (sd=4,770), and the age range is from 28 to 56 years. In order to achieve the stated objectives, the following questionnaires were used: Questionnaire of life events during the past year, Self-assessment of deterioration of life due to the COVID-19 pandemic, Scale of concern about the COVID-19 pandemic, Scale satisfaction with marriage/relationship, Multidimensional scale of perceived social support (MSPSS). The results showed that a high percentage of mothers were in self-isolation due to the COVID-19 pandemic, got over the virus, reported a decrease in financial income and experienced the death of a loved one. Also, hierarchical regression analysis found that socio-demographic data, concern about the COVID-19 pandemic, satisfaction with marriage/relationship, and perceived social support significantly predict the self-assessment of deterioration of daily life due to the COVID-19 pandemic. Mothers' level of education, satisfaction with marriage/relationship, and worry about the pandemic proved to be significant predictors in predicting the deterioration of life due to the pandemic, in such a way that the less educated, less satisfied with marriage/relationship and more worried about the pandemic, estimate a greater deterioration of life.
