“…The increased risk of violence has been reported in several longitudinal studies (Capaldi and Stoolmiller, 1999; Kofler et al , 2011; Fazel et al , 2015; Yu et al , 2017) including using sibling and twin designs (Fazel et al , 2015). In addition, other designs, including cross-sectional and prevalence studies in selected samples, are consistent with this link (Arseneault et al , 2000; Coid et al , 2006; Fairchild et al , 2008; Ferguson et al , 2009; Piko and Pinczés, 2014). However, inconsistent findings have been reported, as several studies found no clear associations between depression and violent outcomes (Chen et al , 2012; van Dorn et al , 2012; Marsh et al , 2016).…”
