Table 2 Correlations between perceived social support (by the Multidimensional Scale of Perceived Social Support), depression (the Self-rating Depression Scale), anxiety (the Self-rating Anxiety Scale), impulsivity (the Barratt Impulsiveness Scale), and self-injury addiction (the addiction subscale of the Revised Chinese Version of Ottawa Self-injury Inventory) in adolescents with non-suicidal self-injury behaviors (n = 102)
