Key Takeaway
Consider resilience-building as a protective factor in adolescents with social networking addiction and self-injury risk.
This observational cohort study followed 2,628 Chinese high school students over a 12-month period to examine reciprocal relationships between social networking addiction (SNA) and non-suicidal self-injury (NSSI), and the moderating role of psychological resilience. The study did not report a comparator group or specific setting.
Main results showed significant, positive, and reciprocal cross-lagged effects between SNA and NSSI. SNA predicted NSSI with effect sizes (βs) of .19 and .17, while NSSI predicted SNA with effect sizes (βs) of .14 and .12. Resilience moderated the pathway from SNA to NSSI: the effect was strong and significant (β = .25) for low resilience, but rendered non-significant (β = .07) for high resilience.
No safety or tolerability data were reported, as adverse events, serious adverse events, and discontinuations were not reported. Key limitations include the observational design, which cannot establish causality, and the lack of reported p-values or confidence intervals for the effect sizes.
Practice relevance suggests integrated, dual-focus interventions addressing both online and offline maladaptive behaviors, with resilience-building as a primary prevention strategy. The findings indicate bidirectional effects between SNA and NSSI, with resilience acting as a protective buffer, but certainty is limited by the study design.

BackgroundThe reciprocal relationship between social networking addiction (SNA) and non-suicidal self-injury (NSSI) represents a critical, yet poorly understood, feedback loop in adolescent psychopathology. This study aimed to longitudinally test a “vicious cycle” model, examining the bidirectional effects between SNA and NSSI, and to investigate psychological resilience as a potential protective factor that could disrupt this harmful dynamic.MethodsA three-wave longitudinal study was conducted with a large cohort of 2,628 Chinese high school students (mean age = 16.1 years; 53.1% female) over a 12-month period. Participants completed measures of SNA, NSSI frequency, and psychological resilience at each wave. A cross-lagged panel model (CLPM) was used to examine the reciprocal, prospective relationships between SNA and NSSI. A multi-group CLPM was then employed to test the moderating role of resilience.ResultsThe CLPM revealed significant, positive, and reciprocal cross-lagged effects. SNA at T1 and T2 prospectively predicted increases in NSSI at T2 and T3, respectively (βs = .19 and.17). Conversely, NSSI at T1 and T2 prospectively predicted increases in SNA at T2 and T3 (βs = .14 and.12), providing robust evidence for a vicious cycle. Furthermore, resilience significantly moderated the pathway from SNA to NSSI. For adolescents with low resilience, the effect was strong and significant (β = .25), whereas for those with high resilience, the effect was rendered non-significant (β = .07).ConclusionsSocial networking addiction and non-suicidal self-injury are not merely comorbid but are locked in a mutually reinforcing developmental spiral over time. However, this dangerous cycle is not deterministic. Psychological resilience acts as a powerful protective buffer, effectively uncoupling the link from addictive social media use to self-harm. These findings underscore the urgent need for integrated, dual-focus interventions that address both online and offline maladaptive behaviors, while championing resilience-building as a primary strategy for prevention.
