“…Despite limited empirical research into the validity of the TTM as it applies to the offending population, the model has been commonly utilised within correctional practice (Casey et al, 2005). The TTM has been used to evaluate behavioural change for substance abuse (D'Sylva et al, 2012), sexual offending (Tierney & McCabe, 2001), intimate partner violence (Gilchrist et al, 2015), general violence (Howells & Day, 2006), forensic mental health treatment (McMurran et al, 1998), juvenile males (Levesque et al, 2012) and motivational programmes (Anstiss et al, 2011;Yong et al, 2015). However, the appropriateness of applying TTM to this population has been debated (Anstiss et al, 2011;Austin, Williams, & Kilgour, 2011;Burrowes & Needs, 2009;Casey et al, 2005;Polaschek, Anstiss, & Wilson, 2010).…”
