摘要:This research aimed to examine the association between life satisfaction and family climate indicators in 12-year-old European adolescents. Cross-sectional data from the second wave of the Children’s Worlds project—an international survey of children’s lives and well-being—were examined. Specifically, data from participating European countries were analyzed: i.e., Estonia, Spain, Germany, England, Romania, Norway, Poland, and Malta. This sample of 9281 adolescents (50.3% girls) filled in self-report measures of life satisfaction and some indicators of family climate. Descriptive statistics and regression analyses were performed by country. Furthermore, a confirmatory model was tested to examine the association between family climate and life satisfaction. The results pointed out that having a good time together with family and being treated fairly by parents/carers were the indicators with the greatest positive effects on life satisfaction. In general, a more positive family climate was associated with higher life satisfaction among 12-year-old adolescents in the participating eight European countries.
