more efficacious than wait-list control with effect sizes <strong>of</strong> d = 0.83 – 2.05 for treatments<br />
<strong>and</strong> an average d = 0.29 for wait-list controls. CBT appears to be the superior treatment<br />
because <strong>of</strong> the greater acceptability, strength, breadth, <strong>and</strong> durability <strong>of</strong> the treatment<br />
effects (d = 0.83 – 2.05 <strong>and</strong> average d = 1.74 at follow-up; Clark et al., 1998; Speckens et<br />
al., 1995; Stern & Fern<strong>and</strong>ez, 1991; Visser & Bouman, 2001; Warwick et al., 1996).<br />
Psychoeducation alone (average d = 1.05) may be a sufficient treatment for <strong>in</strong>dividuals<br />
with mild health anxiety without depression (Avia et al., 1996; Bouman, 2002; Lidbeck,<br />
1997). CBT may be the superior treatment for <strong>in</strong>dividuals with health anxiety <strong>and</strong><br />
comorbid depression or generalized anxiety (average depression d = 1.36; average<br />
generalized anxiety d = 1.90; Clark et al., 1998; Speckens et al., 1995; Stern &<br />
Fern<strong>and</strong>ez, 1991; Visser & Bouman, 2001; Warwick et al., 1996). Based on the results <strong>of</strong><br />
the CBT studies above <strong>and</strong> more recent studies reviewed below (e.g., Barsky & Ahern,<br />
2004; Bleichhardt et al., 2005; Bouman, 2002; Buwalda, Bouman, & Van Duijn, 2008;<br />
Martínez & Botella, 2005; Seivewright, Green, Salkovskis, Barrett, Nur, & Tyrer, 2008;<br />
Sorensen, Birket-Smith, Wattar, Buemann, & Salkovskis, 2010; Wattar et. al., 2005),<br />
CBT was chosen as the focus <strong>of</strong> the current research as it appears to be more efficacious<br />
than other psychosocial treatments <strong>and</strong> acceptable to <strong>in</strong>dividuals with health anxiety.<br />
Recent studies have exam<strong>in</strong>ed <strong>in</strong>dividual CBT sessions (e.g., Barsky & Ahern,<br />
2004; Seivewright et al., 2008; Sorensen et al., 2010), group CBT sessions (e.g., Bouman<br />
2002; Martínez & Botella, 2005), comb<strong>in</strong>ed <strong>in</strong>dividual <strong>and</strong> group sessions (e.g.,<br />
