anxiety. After ethical clearance was obtained for the study, individuals with maladaptive
levels of health anxiety were recruited in the city of Regina, Saskatchewan. Individuals
completed telephone or online screening followed by an assessment interview and
random assignment to one of two groups. Some were randomly assigned to the SHB
group where they received CBT in book-form (It’s Not All in Your Head, Asmundson &
Taylor; 2005) and weekly in-person or telephone check-ins with a trained facilitator or
the Head Researcher (n = 10; 7 females and 2 males). The SHB treatment was a guided
self-help MC because facilitators or the Head Researcher introduced the self-help book
and helped participants to use it effectively (Mead et al., 2005; Newman et al., 2003).
Other participants were assigned to the WLC group waiting for the SHB treatment (n = 4;
3 females and 1 male). Both conditions had a duration of 8 weeks and all participants
completed questionnaires pre-, mid-, and post-treatment to assess symptoms of health
anxiety, general anxiety, depression, and self-reported physical and mental functioning.
It was hypothesized that using a CBT self-help book would be a more efficacious
treatment than WLC. It was expected that relative to WLC, SHB would be more
efficacious in reducing health anxiety as evidenced by reductions in scores on measures
of health anxiety and related constructs. ITT analysis (LOCF procedure; Hollis &
Campbell, 1999) was used for all participants who were randomly assigned, and
remained in the study until T2 including 4 participants who dropped out of the SHB
group. Paired samples t tests were used to analyze within-group differences. Analyses
