“…The results were often inconsistent and few moderators have been identified. Variables that were shown in some studies to be associated with less favorable treatment response included- demographic variables such as male sex (Blain, Galovski, & Robinson, 2010), younger age (Rizvi et al., 2009; Taylor, Fedoroff, & Koch, 1999), higher level of education (Ehlers et al., 2005) or ethnic minority (Walling, Suvak, Howard, Taft, & Murphy, 2012);
- comorbidity with other anxiety disorders or high symptoms of anxiety and arousal (Rosenkranz & Muller, 2011; Tarrier et al., 2000; but see van Minnen et al., 2002; Richardson et al., 2011; for negative findings); with depression or suicidal ideation (Duffy et al., 2007; Tarrier et al., 2000; but see van Minnen et al., 2002; Richardson et al., 2011; for negative findings); substance abuse (van Minnen et al., 2002; but see Richardson et al., 2011; for negative findings); personality disorders (Clarke, Rizvi, & Resick, 2008; Feeny et al., 2002); use of psychotropic medication (van Minnen et al., 2002), and permanent physical disability resulting from the trauma (Gillespie et al., 2002; but see Duffy et al., 2007; for negative findings);
- trauma characteristics such as multiple trauma (van Minnen et al., 2002), childhood trauma (van Minnen et al., 2002; but also see Jaycox, Foa, & Morral, 1998; for negative findings), interpersonal trauma committed by a perpetrator (van Minnen et al., 2002), longer time since the trauma (Duffy et al., 2007; but see Ehlers et al., 2005; Rizvi et al., 2009; for negative findings).
