Objective: To explore the relationship between self-identity and family factors、parental attachment、sense of security of the migrant laborers’ children. Methods:A battery of questionnaire, including self-identity questionnaire, parental attachment questionnaire and security questionnaire, are performed among 329 students from four elementary or secondary schools for children of migrant works in Chengdu, Sichuan Province. Results: Urban migrant children's sense of security and intimate parental attachment have positive correlation with their self-identity, while anxious, avoidant and dependent parental attachment have negative correlation with their self-identity. The present study shows that father's education level (? =- 0.123), parental emotional relationships (? = 0.107), avoidant (? =- 0.137) and dependent attachment (? = 0.102), sense of interpersonal security (? = 0.338) and sense of determinate security (? = 0.202) can explain 35% of variance in self-identity of these children. Conclusions: Insecure parental attachment relationship and the sense of insecurity will to a large degree influence self- identity of migrant laborers’ children.
