“…International studies on (medium security) forensic psychiatric treatment have presented a mixed picture of recidivism rates that seems to vary from 7.1% to 63% for general recidivism and from 1.8% to 46% for violent recidivism over different follow-up periods of 1 to 10.8 years in NGRI populations (for an overview, see Hayes, Kemp, Large, & Nielssen, 2014) (studies not reported in Hayes et al, 2014;Edwards, Steed, & Murray, 2002;Friendship, McClintock, Rutter, & Maden, 1999;Harris, Rice, & Cormier, 2002;Lund, Hofvander, Forsman, Anckarsater, & Nilsson, 2013;Maden, Scott, Burnett, Lewis, & Skapinakis, 2004;Müller-Isberner, Freese, Jockel, & Gonzalez Cabeza, 2000;Nilsson, Wallinius, Gustavson, Anckarsäter, & Kerekes, 2011;Nowak & Nugter, 2014;Seifert & Moller-Mussavi, 2005;Tabita, de Santi, & Kjellin, 2012). To the best of our knowledge, no meta-analysis of recidivism rates in NGRI patients is currently available.…”
