摘要:Family complexity is increasing in Europe, experienced by a significant proportion of children. More evidence is needed in Europe how children’s family type influences their well-being, especially their family-related subjective well-being, and to what extent parenting practices are playing a role in these relationships. The aim of the paper is to study perceptions of children who live with two biological parents, with a biological and a stepparent, or with a single parent about the parenting practices of their (step)parents and their satisfaction with the people they live with. The analysis is based on the third wave of the “Children’s Worlds” harmonized dataset of 12-year-old children in Estonia, Finland, Hungary, Norway, Poland, and Romania. The findings reveal a ‘cascade of children’s appraisals’ by the family types—overall, living with two biological parents is the least and in a stepparent family the most complex family environment for children, reflected in their highest and lowest evaluations of parenting practices and family-related subjective well-being, respectively. The analyses showed that simple and complex family type differences in children’s family-related subjective well-being are entirely explained by parenting practices in Norway, Estonia, and Poland, but not or almost not at all in Finland, Hungary, and Romania. To conclude, in a caring, safe, and participation-enhancing family atmosphere, children can be inclusively flexible and adapt to new parent-figures.
