“…Less broad physical factors, such as fear of respiratory symptoms (Deacon & Abramowitz, 2006;Muris, 2002;Taylor & Cox, 1998) or fear of cardiovascular symptoms (Muris, 2002;Taylor & Cox, 1998), have also been found. Additionally, previous studies have extracted a number of other cognitive factors, for example an emotional factor (Khawaja & Oei, 1992, 1998Wenzel et al, 2006), a mental or cognitive functioning factor (Deacon & Abramowitz, 2006;Hicks et al, 2005;Khawaja & Oei, 1992, 1998Muris, 2002), a social factor (Deacon & Abramowitz, 2006;Hicks et al, 2005;Khawaja and Oei, 1992;Lovibond & Rapee, 1993;Muris, 2002;Wenzel et al, 2006), or combinations of these, such as socialcognitive concerns (Zvolensky et al, 2003), fear of psychosocial consequences (Marks et al, 1991), or fear of psychological symptoms (Cox et al, 1995). As results of prior studies do not provide a clear hypothesis about the structure of cognitive symptoms, further studies with an explorative approach to data collection and analysis are needed.…”
