“…However, the degree of confidence one can place in these findings is questionable because of pervasive limitations within the literature. For example, to date most studies have involved fewer than 50 FSOs (see Beech et al, 2009; Deering & Mellor, 2011; Faller, 1987; Gannon, Rose, & Williams, 2009; Gannon et al, 2013; Johansson-Love & Fremouw, 2009; Kaplan & Green, 1995; Miccio-Fonseca, 2000; West et al, 2011) and several have fewer than a dozen cases (see Peter, 2008; Travin, Cullen, & Protter, 1990; Vandiver, Dial, & Worley, 2008). Furthermore, most samples are drawn from clinical (e.g., Faller, 1987; Hickey, McCrory, Farmer, & Vizard, 2008; McCartan, Law, Murphy, & Bailey, 2011; Miccio-Fonseca, 2000; Muskens et al, 2011; Travin et al, 1990) or correctional settings (e.g., Ferguson & Meehan, 2005; Gannon et al, 2009; Gannon et al, 2013; Johansson-Love & Fremouw, 2009; Miller, Turner, & Henderson, 2009; Pfugradt & Allen, 2010; Turner, Miller, & Henderson, 2008; Vandiver & Kercher, 2004; Whelan, Farr, & Hammond, 2010).…”
