“…Other methods traditionally considered highly dangerous are poisoning with gases (Elnour & Harrison, 2008), jumping from heights (Abrams, Marzuk, Tardiff, & Leon, 2005), drowning (Miller et al, 2004) and motor vehicle exhaust (Spittal et al, 2012), while poisoning with drugs, pill overdose and other poisons are usually more common in suicide attempts than in complete suicide (Elnour & Harrison, 2008;Fox & Weissman, 1975;Miller et al, 2004;Spicer & Miller, 2000). With regard to gender differences, men usually use more lethal means than women (Cibis et al, 2009): in fact, men tend to use, above all, firearms (Cattell, 2000;Kaplan et al, 2009), while women most often employ self-poisoning (Cattell, 2000;Chen, Park, & Lu, 2009). In addition, elderly people tend to adopt more violent methods as impulsive and aggressive subjects (Dumais et al, 2005).…”
