title: Rumination and emotions in nonsuicidal self-injury and eating disorder behaviors: a preliminary test of the emotional cascade model.
abstract: OBJECTIVE
  This study examined relations between repeated rumination trials and emotions in nonsuicidal self-injury (NSSI) and eating disorder behaviors (EDBs) within the context of the emotional cascade model (Selby, Anestis, & Joiner, 2008).
  
  
  METHODS
  Rumination was repeatedly induced in 342 university students (79.2% female, Mage = 18.61, standard error = .08); negative and positive emotions were reported after each rumination trial. Repeated measures analyses of variance were used to examine the relations between NSSI and EDB history and changes in emotions.
  
  
  RESULTS
  NSSI history associated with greater initial increases in negative emotions, whereas EDB history associated with greater initial decreases in positive emotions. Baseline negative emotional states and trait emotion regulation mediated the relation between NSSI/EDB history and emotional states after rumination.
  
  
  CONCLUSIONS
  Although NSSI and EDBs share similarities in emotion dysregulation, differences also exist. Both emotion dysregulation and maladaptive cognitive processes should be targeted in treatment for NSSI and EDBs.
