Note . NSSI = nonsuicidal self-injuyr; DERS = Difficulties in Emotion Regulation Scale (i.e., emotion dysregulation). The topic proportions sum to one for participants with no history of NSSI and participants with a history of NSSI at each value of DERS. The Dirichlet regression curve estimates are shown for the four topic proportions with the estimated topic proportions and DERS scores for each participant overlaid as points.
