“…disorder severity, sociodemographic characteristics) in order to allow for conclusions to be drawn across multiple anxiety disorders. Based on these criteria, we excluded papers that measured variables after baseline (Burton, Schmertz, Price, Masuda, & Anderson, 2013;Rodebaugh, Heimberg, Schultz, & Blackmore, 2010) or only conducted withingroup analyses (Andersson, Carlbring, & Grimlund, 2008;Brody et al, 1998;Cottraux et al, 1990;De Kleine, Hendriks, Kusters, Broekman, & van Minnen, 2012;Hoexter et al, 2013;Nordgreen et al, 2012;Taylor, 2003). We also set out to exclude studies that solely investigated disorder-specific moderators and to report only the transdiagnostic (relevant to multiple anxiety disorders) moderators in studies that examined both disorder-specific (e.g., type of social anxiety disorder, Hedman et al, 2012;dominance of obsessions vs. compulsions, Hohagen et al, 1998;presence of hoarding, Maher et al, 2010) and transdiagnostic moderators.…”
