“…Recently, Chan and Heide (2016) and Stefanska, Beech, and Carter (2016) published respectively a literature review and a systematic review of the differences and similarities between the two groups of offenders. In the systematic review by Stefanska et al (2016), which examined 10 studies, the authors found some differences between SHOs and NHSOs as to their characteristics: namely, SHOs were more likely to have reported loneliness problems (see Grubin, 1994;Higgs, Carter, & Stefanska, 2015;Marshall, 1989;Milsom, Beech, & Webster, 2003;Nicole & Proulx, 2007;Palermo, 2008) as well as anger issues (see Chene & Cusson, 2007;Grubin, 1994). However, the two groups shared the presence of mental disorders (see Grubin, 1994;Oliver, Beech, Fisher, & Beckett, 2007;Proulx & Sauvêtre, 2007), a criminal history of sexual and violent offense (Grubin, 1994;Nicole & Proulx, 2007;Oliver et al, 2007;Vettor & Beech, 2014), dysfunctional family structure (see Nicole & Proulx, 2007;Oliver et al, 2007), and sexual victimization (Grubin, 1994;Nicole & Proulx, 2007;Oliver et al, 2007).…”
