Bleichhardt et al., 2005; Wattar et. al., 2005), and psychoeducational groups (e.g.,
Buwalda et al., 2008). Some studies provided participants with psychoeducational
booklets and other media (e.g., Buwalda et al., 2008; Seivewright et al., 2008). Study
designs included randomized controlled trials with wait-list control groups (e.g., Barsky
& Ahern, 2004; Buwalda et al., 2008; Seivewright et al., 2008), comparison of CBT to
another treatment (e.g., Sorensen et al., 2010), CBT for health anxiety and a comorbid
disorder (e.g., Bleichhardt et al., 2005), or a single-group design (e.g., Bouman, 2002;
Martínez & Botella, 2005; Wattar et. al., 2005). Most of these studies did not provide
effect sizes and when possible, they were calculated using the Effect Size Calculator
(Becker 1999) and presented below.
The latest individual CBT for health anxiety studies included many of the
previously explained components (e.g., cognitive and behaviour therapy, ERP, BSM,
psychoeducation) while some also included mindfulness training (a form of cognitive
therapy; e.g., Sorensen et al., 2010; Wattar et al., 2005) and assertiveness training
(Bleichhardt et al., 2005). Sorensen and colleagues (2010) evaluated the relative efficacy
of CBT (n = 20) and short-term psychodynamic psychotherapy (STPP; n = 20) compared
to a wait-list control (n = 40). The CBT component involved eight individual sessions (45
minutes each) followed by eight group sessions (5-9 participants per group; 90 minutes
each). STPP involved 16 weekly sessions (50 minutes each) focusing on the influence of
the unconscious, the therapeutic relationship, interpersonal interactions, and themes in
