“…Crosssectionally, NSSI is associated with poorer psychosocial wellbeing (Giletta, Scholte, Engels, Ciairano, & Prinstein, 2012;Muehlenkamp, Brausch, Quigley, & Whitlock, 2013;Rotolone & Martin, 2012), and greater psychopathology (Nock, Joiner, Gordon, Lloyd-Richardson, & Prinstein, 2006). Longitudinally, NSSI is a risk factor for poorer psychological wellbeing (Andrews, Martin, Hasking, & Page, 2014;Robinson et al, 2019), the onset of new psychiatric disorders (Wilkinson, Qiu, Neufeld, Jones, & Goodyer, 2018), and suicidality (Ribeiro et al, 2016). Given the important associations and corollaries of NSSI, research into the onset, development, recovery, and prevention of the behavior is critical.…”
