Psychological distress and non-suicidal self-injury: The mediating roles of rumination, cognitive reappraisal and expressive suppression

Résumé

textbfObjectives: This study sought to explore the relationships between depression, anxiety, stress and non-suicidal self-injury (NSSI), and the mediating roles of rumination and emotion regulation in this relationship. textbfMethods: The sample comprised 1,586 Australian university students who completed a self-report questionnaire assessing the relevant variables. textbfResults: Of the sample, 8.9% engaged in NSSI in the four weeks prior to the survey. Depression, anxiety and stress each exerted a direct effect on NSSI, and each relationship was mediated by cognitive reappraisal. The relationship between stress and NSSI was also mediated by expressive suppression. textbfConclusion: The results imply intervention efforts aimed at teaching adaptive emotion regulation strategies for students experiencing high levels of psychological distress may reduce the frequency of NSSI.
