Supplemental Material for Assessment of Nonsuicidal Self-Injury: Development and Initial Validation of the Non-Suicidal Self-Injury–Assessment Tool (NSSI-AT)

Background: Historically, the field of self-injury has distinguished between the behaviors exhibited among individuals with a developmental disability (self-injurious behaviors; SIB) and those present within a normative population (nonsuicidal self-injury; NSSI),which typically result as a response to perceived stress. More recently, however, conclusions about NSSI have been drawn from lines of animal research aimed at examining the neurobiological mechanisms of SIB. Despite some functional similarity between SIB and NSSI, no empirical investigation has provided precedent for the application of SIB-targeted animal research as justification for pharmacological interventions in populations demonstrating NSSI. Aims: The present study examined this question directly, by simulating an animal model of SIB in rodents injected with pemoline and systematically manipulating stress conditions in order to monitor rates of self-injury. Methods: Sham controls and experimental animals injected with pemoline (200 mg/kg) were assigned to either a low stress (discriminated positive reinforcement) or high stress (discriminated avoidance) group and compared on the dependent measures of self-inflicted injury prevalence and severity. Results: The manipulation of stress conditions did not impact the rate of self-injury demonstrated by the rats. The results do not support a model of stress-induced SIB in rodents. Conclusions: Current findings provide evidence for caution in the development of pharmacotherapies of NSSI in human populations based on CNS stimulant models. Theoretical implications are discussed with respect to antecedent factors such as preinjury arousal level and environmental stress.

Nonsuicidal Self Injury

Abstract. Background: Nonsuicidal self-injury (NSSI) has been found to be associated with poor emotion regulation. Aims: The goal of this study was to examine the association of multidimensional cognitive emotion regulation strategies with NSSI among adolescents and compare the different patterns of NSSI. Method: A sample of 594 high-school students (54.4% boys; mean age = 14.96 years), from five regional schools across Israel, were assessed for five facets of cognitive emotion regulation strategies (acceptance, refocus on planning, positive refocusing, putting into perspective, and positive reappraisal) and NSSI behaviors using validated scales. Participants were allocated into three groups: repetitive NSSI (more than six occasions of NSSI; 7.1%), occasional NSSI (at least one incident but less than six; 8.3%), and no NSSI (84.6%). Results: Analysis of covariance, controlling for gender and depression symptoms, revealed that students with NSSI reported higher levels of acceptance, but lower levels of refocus on planning and putting into perspective. Limitations: The study used a cross-sectional design, which was a limitation. Conclusion: These findings demonstrate that particular cognitive emotion regulation strategies differ substantially in their relationship with NSSI. Adolescents who focus on planning and putting stressful situations into perspective may have increased resilience, whereas adolescents who are accepting of negative events that have happened may be more prone to maladaptive coping behaviors.
