Whether NSSI Occurs (Reference: No)		Model 1	Model 2	Model 3
Negative life events		.038***	.039***	.035*
Social support			−.036***	−.033**
Age (reference: 17 and below)	18 and above			−.449
Segment (reference: junior middle school)	Senior middle school			−.671+
−2 log likelihood		549.287***	519.478***	351.625***
