Lifetime frequency of NSSI behaviors was created by rank transforming each of the 12 NSSI behaviors (so that each behavior had the same mean) and then summing the 12 rank-transformed behavior scores to obtain a total frequency score.
Follow-up NSSI frequency (between baseline and 1-year follow-up) was created by rank transforming each of the 12 NSSI behaviors (so that each behavior had the same mean) and then summing the 12 rank-transformed behavior scores to obtain a total frequency score.
Recency of NSSI indicates how many months it had been since an individual engaged in NSSI.
MSI-BPD features total score did not include the suicide/self-injury item.
