  1. DERS Difficulties in Emotion Regulation Scale, CTQ Childhood Trauma Questionnaire, BIS Barratt Impulsiveness Scale, SCARE Screen for Child Anxiety Related Emotional Disorders, PHQ-9 Patient Health Questionnaire
  2. #OR evaluated on the standardized variables. The reference group is NO-NSSI-BE
  3. Unadjusted ORs refer to univariate logistic models results (first step of Baron and Kenny); adjusted ORs were carried out by multiple logistic models and refer to ORs of the personality traits adjusted for the clinical scale. The column of Spearman ρ coefficients represents the association between the traits and clinical scales (second step of Baron and Kenny); the column of adjusted ORs represents the association between personality traits and the group variable adjusted for the corresponding clinical scale (last step of Baron and Kenny)
  4. * Highlights a mediation effect of clinical scale on the relation trait-group: i.e. when the clinical scale is introduced in the multiple logistic model, the ORs associated to traits (column Adjusted# OR) become non-significant and the relative AIC decreases markedly
