In order to analyze the influencing factors of family capital on the family adaptation process among adolescents with school attendance problems, this study adopts qualitative research method, using in-depth interview method and physical collection method for data collection, and adopting situational analysis and analogical analysis method to analyze the case data. The subjects of the study were adolescents and their parents who voluntarily participated in the study from September 2021 to March 2023, having attendance problems for more than one semester. The results indicate a close relationship between the family adaptation process and their family capital, which includes social, cultural, economic, and psychological aspects. Economically affluent families can offer substantial financial support to facilitate the adaptation of teenagers facing attendance problems. Those with abundant social and psychological capital can assist these children in returning to school or finding alternative paths for their growth. However, families with significant cultural capital may impose excessively high expectations on their children, leading to a more complex impact on the family’s adaptation process.
