According to this risk assessment tool, this study produced an interview framework for teenagers living in the Youth Recovery Center and examined personal and environmental factors. Afterward, Mplus7 latent class layer analysis(LCA) is used to identify groups that are more likely to partake in delinquent behaviors and to estimate the factors that accelerate certain groups to delinquent behaviors. The research shows that adolescent families’ difficulties were most closely contributed to delinquency behavior. Furthermore, dropping out of school is another major factor that triggers adolescent delinquency. This study suggests delinquent behavior can be triggered by teenagers' environmental circumstances. Therefore, a need for attention and care was proposed along with the formation of attachment relationships in environments, such as homes and schools for these teenagers.
