ABSTRACT

Objective:

To explore the chain mediating effect of depression and rumination between negative life events and non-suicidal self-injury(NSSI).

Methods:

Adolescents self-harm scale was used to investigate 1 000 students in a vocational school of Guizhou Province. A total of 333 vocational students with NSSI were screened through, and further investigated by adolescent self-rating life events check list (ASLEC), the center for epidemiological studies depression scale (CES-D), and ruminative Response Scale (RRS). SPSS 25.0 and Mplus 8.1 software were used for data analysis, and the bias corrected percentile Bootstrap method was used to test the mediating effect.

Results:

(1)The scores for negative life events, depression, rumination and NSSI were 67.00 (54.00, 79.00), 47.00 (39.00, 53.50), 64.00 (54.00, 76.00) and 7.00 (2.00, 10.00) respectively.(2)Negative life events were positively correlated with depression ( r=0.29, P<0.01), rumination ( r=0.40, P<0.01), and NSSI ( r=0.18, P<0.01). (3)The mediating effect size of depression between negative life events and NSSI was 0.07, accounting for 38.89% of the total indirect effect.The mediating effect size of rumination between negative life events and NSSI was 0.06, accounting for 33.33% of the total indirect effect.The chain mediating effect of depression and rumination between negative life events and NSSI was 0.05, accounting for 27.78% of the total indirect effect.

Conclusion:

Negative life events can indirectly affect NSSI of vocational education students through depression and rumination, as well as the chain mediating path.
