“…Cognitive theory of anxiety disorders such as OCD (e.g., Salkovskis, 1999; Taylor, 2002) and panic disorder with agoraphobia (e.g., Austin & Richards, 2001; Beck, 1988; Clark, 1986, 1988, 1996; Taylor, 2000), attributes the cause of these disorders to irrational thinking, whereby patients catastrophically misinterpret harmless stimuli, such as bodily sensations in panic disorder and dirt in OCD. CBT treats these disorders by confronting patients with evidence that is inconsistent with their belief, either through in vivo exposure or cognitive information, which supposedly educates patients to interpret the stimuli rationally (e.g., Beck, 1988; Clark, 1988; Gelder, Clark, & Salkovskis, 1993; Hoffart, 1993; Salkovskis, Hackmann, Wells, Gelder, & Clark, 2006; Taylor, 2000).…”
