Key result
Higher physical activity and psychological resilience linked to lower non-suicidal self-injury risk in adolescents.
Why the study?
Non-suicidal self-injury among adolescents is an important public health concern, prompting examination of its associations with physical activity and psychological resilience.

Do physical activity and psychological resilience reduce non-suicidal self-injury in Chinese adolescents?
Interventions promoting physical activity and psychological resilience may help reduce the risk of non-suicidal self-injury among adolescents.
Supports school-based programs targeting physical activity and resilience; leaves open causal effects on non-suicidal self-injury.
Non-suicidal self-injury (NSSI) among adolescents is an important public health concern. This study examined the associations among physical activity (PA), psychological resilience (PR), and NSSI among 2257 junior high school students aged 12–17 years in central China. Using both variable-centered and person-centered approaches, the study found that higher PA and higher PR were related to lower NSSI. PR also partly accounted for the association between PA and NSSI, suggesting that resilience may be one pathway linking physical activity to reduced self-injury risk. Latent profile analysis identified three PA–PR profiles: low, moderate, and high. Adolescents in the low PA–PR profile reported the highest NSSI risk, whereas those in the high PA–PR profile reported the lowest risk. These findings suggest that interventions promoting PA and resilience may help reduce adolescent NSSI risk.

Hu et al. (2026) conducted a cross-sectional in Non-suicidal self-injury (NSSI) (n=2,257). Physical activity and psychological resilience was evaluated on Non-suicidal self-injury (NSSI). Higher physical activity and psychological resilience were associated with lower risk of non-suicidal self-injury among adolescents, with the lowest risk observed in the high PA-PR profile.
