Network analysis of adolescent non-suicidal self-injury subgroups identified through latent profile analysis

Figure 1 Regularized partial correlation influence factor-resilience network across three subgroups: Edge thickness represents the strength of association. Blue (solid) lines indicate positive relationships, whereas red (dashed) lines indicate negative relationships. Only edges with weights greater than 0.05 are displayed. Edge weights are scaled according to the maximum edge weight across all points (0.65). A: Subgroup designations: Non-suicidal self-injury (NSSI)-without depression (ND); B: Subgroup designations: NSSI-with depression; C: Subgroup designations: No NSSI-ND.

Figure 2 Standardized node strength centrality and bridge strength of influence factors across three non-suicidal self-injury datasets. A: Node strength; B: Bridge strength. The networks are labeled as follows: Network 1 = Non-suicidal self-injury (NSSI)-without depression (ND), Network 2 = NSSI-with depression, Network 3 = No NSSI-ND. Refer to Table 2 for the complete names of influence risk factors.

Figure 3 Estimated correlation stability coefficient (cs-coefficient) with bootstrapped 95%CI: The CS-coefficient ranges from 0 to 1, where values above 025 indicate moderate stability, and values above 05 indicate strong stability. Edge-weight difference tests and centrality difference tests were conducted for each network. A: Non-suicidal self-injury (NSSI)-without depression (ND); B: NSSI-with depression; C: No NSSI-ND. AB: Bullying Attitudes; BL: Bullied; EA: Emotional abuse; EC: Emotional control; EN: Emotional neglect; FP: Father's overprotective parenting style; FR: Father's reject parenting style; FS: Family support; FW: Father's Warm Parenting Style; Il: Interpersonal interactions; MP: Mother's overprotective parenting style; MR: Mother's reject parenting style; MW: Mother's warm parenting style; PA: Physical abuse; PB: Bullying; PC: Positive cognition; PN: Physical neglect; SA: Sexual abuse; SI: Smartphone addiction-inefficiency; SO: Smartphone addiction-out control; SV: Smartphone addiction-avoidance; SW: Smartphone addiction-withdrawal; TF: Targeted focus.
