Extended Data Fig. 1: Psychosocial characteristics of SIT and SIB transition group.

a–c: Psychological characteristics (NControl = 6743, NSIT = 282, NSIB = 241) measured by Behavioral Inhibition/Activation Scales (BIS/BAS), including behavioral inhibition (BIS, motivation to avoid aversive outcomes), reward responsiveness (that is, sensitivity to reward), and drive (that is, intensity of goal-directed behavior). d–g: Psychopathological characteristics (NControl = 6747, NSIT = 282, NSIB = 241), including general psychopathology (that is, p-factor) and dimensional psychopathology (that is, conduct problems, internalizing, and ADHD). h, i: Social characteristics (NControl = 6732, NSIT = 282, NSIB = 240), including family support and school support. Center lines in the boxplots represent median values, box limits represent the 25th and 75th percentiles, respectively. The whiskers extend to the most extreme data points not considered outliers. Abbreviations: Control = no-transition control group; SIT = self-injurious thoughts transition group; SIB = self-injurious behaviors transition group.
