Background: Temperament and character traits of adolescents with nonsuicidal self-injury disorder (NSSI) might differentiate those- with and without comorbid borderline personality disorder (BPD).
Results: Adolescents with NSSI disorder scored significantly higher on novelty seeking and harm avoidance and lower on persistence, self-directedness, and cooperativeness than CC. The NSSI + BPD group scored even higher than the NSSI − BPD group on novelty seeking and harm avoidance and lower on persistence and cooperativeness (d ≥ 0.72). Adolescents with NSSI reported higher levels of impulsivity than the CC and NC group. However, this difference was not found in a Go/NoGo task.
Conclusions: The results provide further evidence for a distinct diagnostic entity of NSSI disorder.
