OBJECTIVES This study sought to empirically examine the Emotional Cascade Model of nonsuicidal self-injury (NSSI), and to examine if body regard mitigates these variables' impact on NSSI in college students. We tested a three-way interaction between emotional reactivity, maladaptive cognitive regulation strategies, and body regard predicting NSSI frequency. METHODS Two thousand sixty-six undergraduate students (Mage  = 20.38; 72.4% identified as female; 91.7% White; 22.7% with NSSI) completed measures of emotion reactivity, maladaptive cognitive regulation strategies, body regard, and lifetime NSSI frequency. RESULTS The three-way interaction between emotion reactivity, maladaptive cognitive regulation strategies, and body regard was significant. The interaction effect of emotional reactivity and maladaptive cognitive regulation strategies on NSSI was significant when body regard was low but not significant at average and high levels of body regard. The highest NSSI frequency was reported by those high in emotion reactivity and maladaptive cognitive regulation strategies, and low in body regard. CONCLUSION These results support the emotional cascade theory of NSSI, and support assertions that body regard might act as a protective barrier against NSSI in the context of heightened emotion reactivity and maladaptive cognitive regulation strategies.
