The independent and joint developmental trajectories of depression and self-injury were investigated in 859 junior middle school students by 3-year longitudinal measurements. Furthermore, the current study examined the role of three kinds of important interpersonal relationships (parent-child relationship, peer relationship, and teacher-student relationship) in the co-development of depression and self-injury. The results indicated that there were 4 and 3 heterogeneous developmental trajectories of depression and self-injury in early adolescence, respectively. The joint developmental trajectories of the two include “Low-depression low-self-injury stable,” “Low-depression low-self-injury increase,” and “Moderate-depression moderate-self-injury decrease.” Parental psychological control and peer acceptance were risk and protective factors for early adolescent depression and self-injury, respectively.
