“…Particularly, according to the current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; American Psychiatric Association, 2000), worry is the cardinal feature of the generalized anxiety disorder (GAD) (Decker, Turk, Hess, & Murray, 2008;Dupuy & Ladouceur, 2008;Fisher & Wells, 2009) and it is also present in 40-60% of all anxiety disorders (Barlow, 2002), mood disorders (Starcevic, 1995;Starcevic et al, 2007), somatoform disorders (Robbins & Kirmayer, 1996), and schizophrenia spectrum disorders (Foster, Startup, Potts, & Freeman, 2010;Morrison & Wells, 2007;Startup, Freeman, & Garety, 2007). At present, it is not surprising to note the relatively systematic investigation of the factors that produce and sustain worry (Davey, Eldridge, Drost, & MacDonald, 2007;Gosselin et al, 2007;Hirsch, Hayes, & Mathews, 2009;Ladouceur, Gosselin, & Dugas, 2000;Pratt, Tallis, & Eysenck, 1997;Stöber, Tepperwien, & Staak, 2000;Verkuil, Brosschot, Borkovec, & Thayer, 2009). …”
